Mozi (Mo Di, c. 470–391 BCE) was a seminal Chinese philosopher and founder of Mohism, a major intellectual movement of the Warring States period. Born into modest circumstances, probably in the State of Lu, he is thought to have had training in crafts or engineering, which informed his down‑to‑earth, practical orientation. In contrast to the ritual and lineage‑centered outlook of early Confucianism, Mozi advocated jian’ai—often translated as “impartial concern” or “universal love”—arguing that social disorder arises from partiality and that people should care for others’ families as their own. Mozi organized a disciplined community of followers who combined ethical teaching with technical expertise in defensive warfare. He traveled among competing states, advising rulers to elevate the worthy, govern frugally, practice simple funerals, and renounce aggressive war. The composite text Mozi preserves his speeches, policy essays, and, in later layers, sophisticated discussions of language, inference, and standards of knowledge. Though Mohism eventually declined as an institutional school, Mozi’s critiques of hereditary privilege, luxury, fatalism, and offensive war, along with his insistence on benefiting “the world under Heaven,” make him one of the most striking voices of early Chinese philosophy and an important reference point for contemporary discussions of consequentialism and political ethics.

Central Thesis

Mozi’s core thesis is that social order and “benefit to the world” (利天下) are best achieved when rulers and common people alike adopt impartial concern (兼爱)—caring for others as they care for themselves—guided by objective standards (法) derived from Heaven’s will and the observed consequences of actions, thereby rejecting partiality, luxury, fatalism, and aggressive warfare in favor of meritocratic, frugal, and peace‑oriented governance.

Key Quotes
The way of universal love is to regard the states of others as one’s own state, the families of others as one’s own family, the persons of others as one’s own person.
Mozi, “Jian’ai Zhong” (Impartial Concern, Middle)

Mozi defines the practical content of jian’ai, urging people to extend their concern beyond their own kin and polity to all under Heaven.

Partiality is the great harm of the world. When everyone regards their own state alone, there is disorder among states; when everyone regards their own family alone, there is disorder among families; when everyone regards their own person alone, there is danger to their own person.
Mozi, “Jian’ai Shang” (Impartial Concern, Upper)

Mozi diagnoses partiality—caring only for oneself and one’s immediate circle—as the root of warfare and social conflict.

What the sage‑kings took as the basis of order was this: elevate the worthy and employ the capable—this is the foundation of governing the state.
Mozi, “Shangxian Shang” (Elevating the Worthy, Upper)

Mozi contrasts merit-based appointment of officials with hereditary privilege, arguing that political stability depends on promoting the morally and technically competent.

Now to kill one person is called unrighteous and is punished with death, but to attack a state and kill many is called righteous and rewarded. This is to confuse the standards of righteousness.
Mozi, “Fei Gong Shang” (Against Offensive War, Upper)

In condemning aggressive warfare, Mozi exposes what he sees as a moral double standard that glorifies mass killing when done by states.

Heaven desires righteousness and hates unrighteousness. Therefore it blesses the righteous and brings calamity upon the unrighteous.
Mozi, “Tianzhi” (The Will of Heaven)

Mozi appeals to Heaven as a moral authority whose will aligns with socially beneficial actions, grounding his consequentialist ethics in a religious framework.

Intellectual Development

Formative and Technical Apprenticeship

In his early life, Mozi is traditionally said to have come from a lower social stratum, possibly working as an artisan or technician. Exposure to practical crafts, measurement, and defensive engineering likely contributed to his suspicion of costly ritual, his focus on concrete benefits, and his comfort with technical, almost proto‑scientific reasoning. This phase set him apart from elite, ritualist Confucian lineages.

Founding of the Mohist Community

As Mozi began teaching, he attracted followers who formed a tightly organized group, sometimes described as having quasi‑military discipline. In this period he shaped the core Mohist doctrines: impartial concern (兼爱), condemnation of offensive war (非攻), elevation of the worthy (尚贤), frugality in use (节用) and funerals (节葬), and opposition to fatalism (非命). His group offered rulers not only advice but also practical expertise in fortification and defense.

Political Engagement and Ethical Polemics

During his mature years, Mozi traveled among Warring States polities to counsel rulers. He engaged in debates with Confucians, proponents of lavish ritual and music, and with advocates of fatalistic doctrines. Many early chapters of the Mozi likely stem from this period: direct argumentative essays targeted at concrete policies such as war, taxation, burial customs, and appointment of officials.

Systematization and Proto‑Mohist Logic (early legacy phase)

While probably dating slightly after Mozi’s own lifetime, the so‑called ‘later Mohist’ chapters on definitions, standards, and disputation (辩, bian) grow out of his school’s intellectual trajectory. They refine his concern for objective standards (法, fa) and for aligning names with realities (名实, ming‑shi) into a more systematic treatment of semantics, methodology, and criteria for knowledge, extending the technical spirit of his thought.

1. Introduction

Mozi (Mo Di, c. 470–391 BCE) is widely regarded as the founder of Mohism (墨家), one of the major intellectual movements of early China during the late Spring and Autumn and Warring States periods. Active roughly a generation after Confucius, he developed a systematic critique of hereditary hierarchy, extravagant ritual, and aggressive warfare, proposing instead a vision of society ordered by impartial concern (兼爱, jian’ai), benefit to the world (利天下, li tianxia), and objective standards (法, fa) for policy and moral judgment.

The composite text Mozi preserves a wide range of materials: political essays, moral treatises, religious and cosmological discussions, and, in later layers, some of the most technically sophisticated reflections on language and argumentation in pre-Qin China. These writings depict Mozi as both a moral teacher and a practical adviser, leading a disciplined community that combined ethical teaching with expertise in defensive warfare and engineering.

Modern scholarship commonly highlights several distinctive themes:

  • An ethic of impartial concern that challenges kin-centered partiality
  • A strongly consequentialist orientation, measuring doctrines by their social benefits and harms
  • Advocacy of meritocratic government, frugality, and opposition to offensive war
  • Reliance on a moralized conception of Heaven (天, tian) as a source of normative authority
  • A concern for precise terminology, clear reasoning, and publicly checkable standards

There is significant debate about how unified the Mozi text is, how far it reflects Mozi’s own views as opposed to later Mohists, and how to situate Mohism relative to Confucianism, Legalism, and other schools. Despite the eventual decline of Mohism as an organized movement, Mozi’s ideas remain central to the study of Chinese philosophy and are increasingly discussed in comparative ethics, political theory, and philosophy of religion.

2. Life and Historical Context

2.1 Biographical Outline and Uncertainties

Reliable biographical data about Mozi are sparse. Traditional sources and internal evidence in Mozi suggest:

  • Birth and background: He was likely born around 470 BCE, probably in the State of Lu. Many accounts portray him as coming from modest or artisan origins, possibly trained in crafts or engineering. Some scholars see this as a later construct to explain his practical orientation; others regard it as historically plausible.
  • Career and travels: Mozi appears as an itinerant teacher and adviser, moving among states such as Song and Chu. The text’s narrative portions describe him advising rulers, intervening in military crises, and organizing defensive efforts.
  • Death: His death is usually placed around 391 BCE, but classical sources give few details. Later stories about his final years are often regarded as legendary.

Because early Chinese texts freely mix history and didactic storytelling, historians tend to treat detailed anecdotes—such as his ten-day march to Chu to prevent an attack on Song—as illustrative of Mohist values rather than strictly verifiable events.

2.2 Political and Social Setting

Mozi’s lifetime coincided with the transition from the late Spring and Autumn period to the early Warring States era, marked by:

FeatureRelevance to Mozi
Fragmented feudal orderMultiple states competing for hegemony created a demand for persuasive advisers and practical doctrines.
Intensifying warfareRepeated conflicts provided the backdrop for Mohist opposition to aggressive war and development of defensive techniques.
Social mobilityErosion of aristocratic monopoly on office opened space for “masters” (子) like Mozi to influence rulers through teaching.
Intellectual pluralismThe so‑called Hundred Schools of Thought provided a context of intense debate among Ru (Confucians), Daoists, Legalists, and others.

2.3 Position in the Early Chinese Intellectual Field

Mozi is generally seen as:

  • Chronologically later than Confucius but earlier than Mencius and Xunzi.
  • A major rival to early Confucians, as indicated by sustained Mohist–Ru polemics.
  • A precursor to later, more technical Mohists, whose logical and epistemic work developed out of the movement he founded.

Some historians emphasize continuities between Mohist and emerging Legalist ideas (e.g., stress on standards, merit, and order), while others stress Mozi’s distinct religious and egalitarian elements. There is no consensus on whether Mohism should be viewed primarily as a “philosophical school,” a socio-religious movement, or a quasi-military brotherhood; many scholars see it as combining all three aspects.

3. Sources and Textual History of the Mozi

3.1 Structure of the Surviving Text

The received Mozi consists of 53 chapters (pian), often grouped into clusters:

Cluster (conventional)Content focus
Ethical–political essays (e.g., Jian’ai, Fei Gong, Shangxian)Impartial concern, anti-war doctrine, meritocracy, frugality
Religious and cosmological chapters (e.g., Tianzhi, Ming gui)Will of Heaven, ghosts and spirits, reward and punishment
“Dialectical” or “Canonical” chapters (Jing, Jing shuo, Daqu)Definitions, logical and semantic analysis, standards of knowledge
Narrative and exemplary materialsAnecdotes about Mozi and Mohist followers, model stories of sage-kings

Many chapters appear in triplicate (upper, middle, lower), with overlapping but not identical content, suggesting successive layers of composition and redaction.

3.2 Authorship and Redaction

Scholars generally agree that:

  • The Mozi is a composite work, likely compiled over several generations of Mohists.
  • Some core chapters (often those on impartial concern, elevating the worthy, and condemning offensive war) are probably closest to Mozi’s own teaching, though their exact wording may have been edited.
  • The “later Mohist” Canons (Jing) and Explanations (Jing shuo) represent the work of successors, not Mozi himself.

Debate continues over which passages should be dated early or late. Stylistic analysis, doctrinal development, and intertextual references are all used as criteria, with no fully agreed chronology.

3.3 Manuscript Transmission and Loss

The textual history includes:

  • Early references: Other Warring States and Han texts (such as Han Feizi and Xunzi) cite Mohist ideas, confirming the school’s prominence.
  • Han dynasty catalogues: Bibliographies describe a longer Mozi than the received text, implying that some material has been lost.
  • Medieval redactions: Commentators such as Sun Yirang (Qing dynasty) and others have noted corrupt or repetitive passages, proposing reconstructions or excisions.

The received text appears to have undergone substantial condensation and rearrangement, with some chapters lost entirely and others partially duplicated.

3.4 Commentarial Traditions and Modern Editions

Pre-modern commentary on Mozi is relatively sparse compared with the Confucian classics, contributing to interpretive difficulties. Important modern editions and studies—by scholars such as Sun Yirang, Mei Yibao, Liang Qichao, and later Western and Japanese sinologists—have:

  • Proposed emendations of corrupt graphs and reorganizations of chapter order.
  • Debated the division between “early” and “later” Mohist materials.
  • Offered differing translations of key terms (e.g., 兼爱, 法, 天), reflecting broader interpretive disagreements.

There is no single standard edition or interpretation; researchers typically consult multiple critical editions and commentaries when working with the Mozi text.

4. Intellectual Development and the Mohist Community

4.1 Phases of Mohist Intellectual Development

Drawing on internal evidence and comparative dating, scholars often distinguish several stages:

Phase (approximate)Characteristics
Early or “Foundational” MohismFocus on ethical–political doctrines: impartial concern, anti-war, frugality, meritocracy, and opposition to fatalism. Style is exhortatory and polemical.
Middle MohismExpansion of religious and cosmological themes, more systematic grounding of ethics in Heaven’s will and ghostly sanctions.
Later MohismDevelopment of technical discussions of names, standards, and disputation in the Canons and Explanations; intense interest in semantics and epistemology.

This periodization is widely used but remains contested. Some scholars argue that “early” and “later” Mohism should not be sharply separated, emphasizing continuities in concern for fa (standards) and practical reasoning.

4.2 Social Organization of the Mohist Community

The Mozi and later traditions depict Mohists as a tightly knit community:

  • Quasi-military discipline: The school is portrayed as having ranks, internal leaders, and strict rules of obedience. Followers were expected to risk their lives for defensive missions.
  • Ethical vows: Mohists committed to doctrines such as impartial concern, frugality, and opposition to offensive war, treating them as binding norms.
  • Itinerant service: Groups of Mohists traveled to assist states in fortification and defense, lobbying rulers to adopt Mohist policies.

Historians differ on how literally to take the quasi-military descriptions. Some see the community more as an “ethical fellowship” or “religious order,” while others stress its practical function in military engineering and diplomacy.

4.3 Relation Between Master and School

The link between Mozi himself and “Mohism” is both central and problematic:

  • Many early chapters refer to “Master Mo” in the third person, suggesting they were compiled by disciples.
  • Doctrinal elaborations in later layers indicate active reinterpretation, not just preservation, of his teachings.

Some scholars interpret Mohism as a living tradition that revised Mozi’s ideas to meet new intellectual challenges, particularly those posed by rival schools and evolving statecraft. Others seek to reconstruct a more “original Mozi” by peeling away later accretions. The lack of independent biographical sources makes it difficult to decide which doctrines should be attributed directly to Mozi and which belong to later Mohists, and current scholarship typically presents “Mohist” positions with explicit attention to these stratification issues.

5. Major Works and Doctrinal Clusters

5.1 The Mozi as the Core Corpus

All major knowledge of Mozi’s thought comes from the composite work Mozi, which incorporates both early and later Mohist materials. Unlike the Confucian tradition, there is no parallel corpus such as “sayings” versus “commentary”; instead, the single text contains:

  • Systematic argumentative essays
  • Narrative exempla
  • Religious treatises
  • Technical “canons” and explanations

5.2 Principal Doctrinal Clusters

Scholars often organize the Mozi around recurrent doctrinal clusters, corresponding to named chapter groups:

ClusterKey chaptersCentral themes
Impartial Concern (兼爱, Jian’ai)Jian’ai shang, zhong, xiaAdvocacy of impartial concern/universal love; diagnosis of partiality as source of disorder; consequentialist justification.
Anti-War Doctrine (非攻, Fei Gong)Fei gong shang, zhong, xiaCondemnation of offensive warfare; critique of double standards about killing; permissibility of defensive war.
Meritocracy (尚贤, Shangxian; 尚同, Shangtong)Shangxian shang, xia; Shangtong shang, xiaElevating the worthy, appointing capable officials, political unity through alignment with superior models (Heaven, sage-kings).
Frugality (节用, Jie Yong; 节葬, Jie Zang)Jie yong shang, xia; Jie zang shang, xiaModeration in expenditure and funerals; critique of luxury, elaborate ritual, and waste.
Against Fatalism (非命, Fei Ming)Fei ming shang, zhong, xiaRejection of fate as fixed; emphasis on effort and good governance in determining outcomes.
Heaven, Ghosts, and SpiritsTianzhi; Ming gui; Gui shiWill of Heaven, existence and role of spirits, supernatural rewards and punishments.
Later Mohist Canons and ExplanationsJing shang, xia; Jing shuo shang, xia; DaquDefinitions, logical distinctions, criteria of correct inference, analysis of names and objects.

5.3 External References and Lost Materials

Other early texts attribute sayings or policies to Mozi and Mohists, sometimes not fully reflected in the received Mozi. Han bibliographic records list more chapters than now survive, including materials on music and ritual that may have been lost or heavily condensed. Some scholars infer additional doctrinal concerns (for example, more detailed economic proposals) from these notices, but such reconstructions remain speculative.

Overall, the Mozi is treated as both a single canonical work and a collection of doctrinal dossiers, each reflecting particular aspects and phases of Mohist activity.

6. Core Philosophy: Impartial Concern and Benefit to the World

6.1 Impartial Concern (兼爱, Jian’ai)

The doctrine of jian’ai lies at the heart of Mohist ethics. The key idea is that people should extend their concern beyond themselves and their kin to all others, regarding “others’ states as one’s own state, others’ families as one’s own family.”

“The way of universal love is to regard the states of others as one’s own state, the families of others as one’s own family, the persons of others as one’s own person.”
Mozi, “Jian’ai Zhong”

Proponents of reading Mozi as advocating universal love emphasize this language of equivalence and argue that he calls for dramatically reducing the moral privilege of one’s own kin or state. Others prefer “impartial concern,” stressing that Mozi is primarily attacking harmful partiality, not necessarily erasing all role-specific obligations. On this view, Mohist ethics requires that rulers, ministers, and commoners adopt policies and attitudes that take everyone’s welfare comparably into account.

6.2 Diagnosis of Partiality and Social Disorder

Mozi links social chaos to partiality (偏):

“Partiality is the great harm of the world. When everyone regards their own state alone, there is disorder among states; when everyone regards their own family alone, there is disorder among families.”
Mozi, “Jian’ai Shang”

He argues that wars, theft, and interpersonal conflicts arise when individuals and rulers prioritize their own interests over those of others. Impartial concern is presented as the remedy: if all enlarged their circle of concern, mutual attacks would cease and cooperative benefit would flourish.

6.3 Benefit to the World (利天下, Li Tianxia)

A distinctive feature of Mohist thought is its explicitly consequentialist orientation. Mozi repeatedly assesses doctrines and policies by their impact on “the world under Heaven”:

Evaluative questionMohist criterion
Does a practice increase wealth and basic livelihood?Then it counts as beneficial (利).
Does it produce order and reduce crime?It is aligned with righteousness and Heaven’s will.
Does it waste resources or cause suffering (e.g., offensive war, extravagant funerals)?It is condemned as harmful and unrighteous.

Many scholars interpret this as a form of impartial, welfarist consequentialism, in which right actions are those that maximally promote the collective benefit of all. Others caution that Mohist reasoning also appeals to tradition (the sage-kings) and Heaven’s commands, and thus should not be assimilated straightforwardly to modern utilitarianism. Debate continues over whether Mozi’s consequentialism is primarily rule-based, act-based, or a hybrid grounded in cosmological assumptions.

6.4 Integration of Impartial Concern and Benefit

In Mohist argumentation, impartial concern is justified by its beneficial consequences: it brings about wealth, population growth, and social order, aligning human behavior with Heaven’s will. Conversely, benefit is defined against the backdrop of impartial concern: benefits that accrue only to a few at the expense of many are rejected. This mutual reinforcement between jian’ai and li tianxia shapes the structure of Mohist moral and political reasoning throughout the text.

7. Political Thought: Meritocracy, Government, and Law

7.1 Elevating the Worthy (尚贤) and Political Recruitment

Mozi’s political theory centers on meritocratic appointment and reward, summarized in the doctrine of shangxian (“elevating the worthy”):

“What the sage-kings took as the basis of order was this: elevate the worthy and employ the capable—this is the foundation of governing the state.”
Mozi, “Shangxian Shang”

He argues that offices and emoluments should go to those with moral integrity and technical competence, regardless of birth. Supporters of a strongly egalitarian reading highlight passages where low-born but capable individuals are preferred over noble but incompetent candidates. Others suggest that Mohist meritocracy still presupposes hierarchical rule; it simply aims to rationalize and moralize the selection of elites.

7.2 Political Unity and Conformity (尚同)

The chapters on shangtong (“exalting unity”) propose a hierarchical system in which each level of society aligns its judgments with those above it, ultimately converging on the standard of Heaven and the sage-king. This is presented as a remedy for disorder caused by competing private norms. Critics have seen in this a proto-authoritarian impulse, emphasizing obedience and uniformity; defenders point out that Mohist hierarchy is constrained by the requirement that rulers themselves align with impartial benefit and Heaven’s will.

7.3 Government, Law, and Standards (法)

Mohists stress the need for clear models or standards (fa) in governance:

Political functionMohist emphasis
Legislation and punishmentLaws should be publicly known and consistently applied; rewards and punishments should track actual merit and harm.
Policy evaluationRulers should test doctrines by checking whether they benefited past sage-kings, accord with present sensory evidence, and produce hoped-for outcomes.
Administrative practiceWritten regulations, measurement, and objective criteria are favored over custom or personal favoritism.

Later Mohist materials elaborate how fa function as public benchmarks for correct naming and decision, influencing both legal and administrative rationality.

7.4 Relation to Other Political Currents

Comparisons with Confucian and Legalist views are frequent in scholarship:

  • With Confucians, Mohists share concern for moral cultivation of rulers, but diverge in their skepticism about aristocratic privilege and ritual refinement.
  • With Legalists, they share emphasis on standards, rewards, and punishments, yet differ in grounding: Mohists insist standards must embody impartial concern and Heaven’s moral will, not just the ruler’s interest.

Some interpreters see Mohism as an early attempt to articulate a technocratic, welfare-oriented state, balancing moral and institutional considerations, while others stress its more religious and communitarian features over purely administrative rationality.

8. Ethics: Frugality, Anti-War Doctrine, and Social Responsibility

8.1 Frugality in Expenditure and Funerals (节用, 节葬)

Mozi’s ethical program prominently includes economic restraint:

  • Jie Yong (Moderation in Expenditure): Advocates limiting public and private spending on luxuries, entertainment, and non-essential projects, arguing that resources should first secure people’s basic livelihood.
  • Jie Zang (Moderation in Funerals): Criticizes elaborate burials and prolonged mourning as wasteful and socially disruptive, calling instead for simple rites that respect the dead without harming the living.

Proponents view these doctrines as early reflections on opportunity cost: spending on display and ritual reduces what is available for food, shelter, and defense. Critics in the classical period, especially Ru thinkers, accused Mohists of undermining cultural refinement and human feeling; modern interpreters debate whether Mohist frugality is compatible with a rich conception of the good life or is narrowly material.

8.2 Anti-War Doctrine and Defensive Warfare (非攻)

The Fei Gong chapters condemn offensive war as both morally wrong and socially ruinous:

“Now to kill one person is called unrighteous and is punished with death, but to attack a state and kill many is called righteous and rewarded. This is to confuse the standards of righteousness.”
Mozi, “Fei Gong Shang”

Mozi denounces aggressive campaigns for glory or territory, emphasizing the massive loss of life and wealth. At the same time, Mohists distinguish offensive from defensive war: they actively assist states in fortification and defense. Scholars interpret this as an early form of just war thinking, permitting war only to repel aggression. Some note tensions between the school’s ethical critique of violence and its practical involvement in military technology; others see this as consistent with a duty to protect the innocent.

8.3 Social Responsibility and Mutual Aid

Mohist ethics extends beyond rulers to ordinary people:

  • Individuals are urged to practice mutual aid, assisting neighbors and strangers in need.
  • Filial piety and loyalty are retained but reframed within a broader commitment to impartial concern.
  • Work, thrift, and reliability are celebrated as everyday virtues that contribute to collective benefit.

The movement’s expectation that members risk their lives for defensive missions is often cited as evidence of a strong ethic of collective responsibility. Debate persists over how far Mohism envisions transforming emotional attachments (for instance, love for one’s family) versus redirecting practical behavior toward broader social outcomes.

Overall, Mohist ethics combines stringent standards of frugality and anti-aggression with an affirmative ideal of a cooperative society in which each person’s basic needs are secured through mutually beneficial practices.

9. Metaphysics and the Will of Heaven

9.1 Heaven as a Moral Agent (天)

In Mohist thought, Heaven (tian) is portrayed not merely as the sky or impersonal order, but as an intentional, morally concerned power:

“Heaven desires righteousness and hates unrighteousness. Therefore it blesses the righteous and brings calamity upon the unrighteous.”
Mozi, “Tianzhi”

Mozi attributes to Heaven will, preferences, and the capacity to reward and punish. This anthropomorphic depiction is used to ground ethical and political norms: what benefits the world is said to be what Heaven wants.

9.2 Metaphysical Structure and Causality

Mohist metaphysics is relatively austere compared with some later traditions. Key features include:

AspectMohist orientation
OntologyEmphasis on concrete, observable things (shi, “actualities”) over abstract metaphysical entities.
CausalityEvents are explained through a mix of human agency, Heaven’s will, and, in some chapters, the actions of ghosts and spirits.
NormativityThe moral order is tied to the structure of the cosmos: Heaven’s will and the patterns set by sage-kings.

Some interpreters describe this as a form of moralized natural order, where the same Heaven that controls seasons and harvests also legislates ethical norms. Others are cautious, noting that Mozi does not offer an explicit theory of substance or universal law comparable to later metaphysical systems.

9.3 The Will of Heaven as Normative Standard

The Tianzhi chapters articulate a threefold test for doctrines: conformity to the deeds of ancient sage-kings, agreement with the testimony of common people, and consistency with observed outcomes. Heaven serves as the ultimate reference point:

  • Rulers must model their policies on what Heaven rewards (e.g., care for the people, impartial concern).
  • Disasters and blessings are interpreted as signs of Heaven’s approval or displeasure.

Modern scholars diverge on how literally to take these claims. Some treat Mohism as a theistic or proto-natural law view, in which Heaven’s will is both descriptively and normatively central. Others argue that appeals to Heaven function didactically—to mobilize belief in order to support socially beneficial norms—while the underlying justification remains fundamentally consequentialist.

9.4 Fate and Human Agency

The Fei Ming (“Against Fate”) chapters attack the notion that outcomes are fixed independently of human effort. Mozi insists that Heaven rewards diligence and good governance; poverty and disorder arise from misrule, not immutable destiny. This reinforces a metaphysical picture in which:

  • The world is responsive to human action.
  • Heaven’s order is compatible with, and indeed demands, active human agency.

Interpretations vary as to whether this yields a consistent metaphysical system or a pragmatic amalgam of religious and ethical claims tailored to combat fatalistic doctrines prevalent in Mozi’s time.

10. Epistemology, Standards (Fa), and Later Mohist Logic

10.1 Epistemic Standards and Methods

Mohists develop an explicit concern with criteria of knowledge. Key early formulations propose that claims be tested by:

  1. Historical precedent: Do they accord with the practices of the sage-kings?
  2. Empirical evidence: Are they supported by direct observation and shared experience?
  3. Practical consequences: Do they, when implemented, produce the expected benefits?

This tripartite method is often cited as an early Chinese analogue to evidence-based reasoning, integrating tradition, observation, and outcome evaluation.

10.2 Fa (Standards) as Epistemic and Practical Guides

Fa (法) are models, rules, or standards used to guide both belief and action:

DimensionFunction of fa
CognitiveProvide benchmarks for judging whether a term is applied correctly to things.
Moral–politicalServe as publicly accessible criteria for evaluating policies and officials.
Practical–technicalFunction as measuring tools and procedural rules in crafts and governance.

Mohists liken fa to carpenter’s tools: just as squares and compasses ensure straight lines and true circles, so standards ensure correctness in names and judgments.

10.3 Later Mohist Canons and Logical Analysis

The Later Mohist chapters—the Jing (Canons) and Jing shuo (Explanations)—contain some of the most sophisticated pre-Qin analyses of language and reasoning. Topics include:

  • Distinctions between names (ming) and actualities (shi).
  • Classification of statements, including conditionals and generalizations.
  • Discussion of analogical reasoning, inference patterns, and error sources.
  • Treatment of part–whole relations, identity, and change.

Scholars disagree on how closely these materials relate to Mozi himself. Some see them as a natural development of his emphasis on standards and correct naming; others argue they represent a distinct intellectual project, perhaps influenced by rival “dialecticians.”

10.4 Interpretive Debates about Mohist Logic

Modern commentators have offered divergent characterizations:

ViewpointMain claim
Proto-logicistThe Later Mohists developed an indigenous logic comparable in rigor to early Greek traditions, though framed differently.
Semantic–pragmatic focusTheir primary concern was correct use of language and practical reasoning, not formal logic.
SkepticalThe “logical” content is fragmentary and opaque; reconstructing a systematic theory risks projecting modern categories onto ancient texts.

There is also discussion of whether Mohist epistemology is fundamentally fallibilist, given its reliance on experience and outcome, or whether appeals to Heaven and sage-kings introduce elements of dogmatism. The overall consensus is that Mohist work on fa, ming–shi, and bian (disputation) represents a major strand of early Chinese reflection on knowledge and argument, even if its exact structure remains contested.

11. Critique of Confucianism and Other Rival Schools

11.1 Critique of Confucian Ritual and Music

Mozi’s most sustained polemics target Ru (Confucians). He accuses them of:

  • Promoting elaborate ritual and music that consume resources without sufficient benefit.
  • Defending lavish funerals and prolonged mourning, which burden the living and hinder economic productivity.
  • Emphasizing kin-based partiality, which Mozi sees as a root cause of disorder.

Confucian responses (seen especially in Mencius and Xunzi) defend ritual and music as essential to moral cultivation and social harmony, and portray Mohist frugality as crude and inhumane. Modern scholars debate whether Mozi misrepresents Ru practices or offers a legitimate critique of their social costs.

11.2 Disagreement over Love and Partiality

A central issue is the Mohist doctrine of impartial concern versus Confucian endorsement of graded love. Confucians contend that affection is naturally structured (strongest toward parents, weaker toward strangers) and that moral life should refine, not flatten, this ordering. Mohists reply that such partiality, when enacted politically, leads to favoritism, war, and neglect of the many. Some interpreters frame this as an early Chinese debate over egalitarian vs. hierarchical ethics, though both sides accept some hierarchical structures.

11.3 Critique of Fatalists and Hedonists

Mozi also attacks:

  • Fatalists (ming jia or proponents of ming): Those who claim that outcomes are predetermined and effort is futile. He argues such views discourage good governance and hard work.
  • Hedonistic or music-loving schools: Sometimes associated with Yang Zhu or other figures, who are portrayed as prioritizing personal pleasure over collective benefit.

These critiques reinforce the Mohist emphasis on responsibility, industry, and socially oriented ethics.

11.4 Relation to Legalism and Other Currents

Mohists share certain concerns with Legalists (Fajia)—notably, the use of standards, rewards, and punishments to secure order. However, Mohists insist that such mechanisms must be guided by impartial concern and Heaven’s will, while Legalist texts often focus on state power and stability. Some scholars posit intellectual cross-influences, arguing that Legalists adapted Mohist ideas about fa and performance-based evaluation but stripped them of religious and egalitarian elements.

Relations with other schools (such as Daoists or the “School of Names”) are less explicitly polemical in the Mozi. Later commentators nonetheless identify overlaps and contrasts—for example, between Mohist activism and Daoist non-action, or between Mohist and “dialectician” interest in names and disputation. Overall, Mohist critiques helped shape the contours of early Chinese philosophical debate, forcing rivals to clarify their positions on war, ritual, and social obligation.

12. Religion, Ghosts, and Ritual in Mohist Thought

12.1 Belief in Ghosts and Spirits

The Mozi treats ghosts and spirits (gui shen) as real and morally significant. Chapters such as Ming gui recount stories of supernatural retribution, arguing that spirits punish wrongdoers and reward the righteous. These narratives are presented as empirically attested, citing reports from multiple states and historical periods.

Interpreters divide on how to understand this:

InterpretationEmphasis
Literal-religiousMohists sincerely affirm a spirit-populated cosmos; ghostly sanctions are a core part of their worldview.
Pragmatic-pedagogicalAppeals to ghosts function mainly to reinforce moral behavior among the populace, regardless of metaphysical truth.
MixedMohists both believe in spirits and recognize their usefulness for governance and ethics.

12.2 Ritual Practice and Its Evaluation

Mozi does not reject ritual as such; rather, he assesses specific practices by their costs and benefits:

  • Approved rituals: Simple sacrifices, respectful but modest funerals, and ceremonies that foster social cohesion without heavy expense.
  • Disapproved rituals: Elaborate burials, prolonged mourning, and costly ceremonies, especially those defended by Confucians as expressions of refinement and emotion.

Rituals are thus evaluated using the same li tianxia criterion as other practices: do they benefit or harm the world? This instrumental evaluation contrasts with Ru views that see certain rites as intrinsically valuable or constitutive of moral life.

12.3 Heaven, Spirits, and Political Order

Mohist religious claims have a pronounced political dimension:

  • Heaven is depicted as appointing rulers and expecting them to care for the people.
  • Ghosts and spirits are portrayed as Heaven’s agents, enforcing moral norms beyond human institutions.
  • Public rituals honoring Heaven and spirits are said to secure blessings and avert calamities, provided they are conducted with sincerity and frugality.

Some scholars view this as an early form of state theology, legitimizing political authority while subordinating it to cosmic moral standards. Others stress continuity with broader Zhou religious traditions, noting that Mohists radicalize rather than invent the idea of Heaven’s moral governance.

12.4 Comparison with Other Religious Outlooks

Compared with Confucianism, Mohism:

  • Places more explicit weight on supernatural sanctions.
  • Tends to simplify ritual rather than elaborate it.
  • Emphasizes reward and punishment rather than self-cultivation through rites.

Compared with later Daoist and Buddhist religiosity, Mohist religion is relatively this-worldly, focusing on prosperity, order, and ethical behavior in the present life. Whether Mohism should be characterized primarily as a religious movement or an ethical-political philosophy with religious elements remains a topic of ongoing debate.

13. Interpretation, Translation Issues, and Modern Scholarship

13.1 Key Translation Controversies

Several Mohist terms have generated substantial debate among translators:

TermMain renderingsIssues
兼爱 (jian’ai)“Universal love,” “impartial concern,” “inclusive care”“Love” may overstate emotional content; “impartial concern” stresses practical treatment but may underplay affect.
利 (li) / 利天下 (li tianxia)“Benefit,” “profit,” “welfare”“Profit” suggests narrow economic gain; “benefit” or “welfare” better capture broad social improvement.
法 (fa)“Law,” “model,” “standard,” “criterion”“Law” risks legalist connotations; “standard” or “model” highlight its broader cognitive and practical role.
天 (tian)“Heaven,” “Sky,” “God”“God” may imply monotheistic theology; “Heaven” preserves Chinese context but can be vague.

Different translations reflect different interpretive stances—for instance, whether one emphasizes Mohism’s religiosity or its rational, consequentialist aspects.

13.2 Interpretive Schools in Modern Scholarship

Modern scholarship on Mozi and Mohism can be broadly grouped into several tendencies:

  • Consequentialist/Proto-utilitarian readings: Emphasize impartial benefit and outcome-based evaluation, aligning Mozi with modern utilitarian ethics.
  • Religious–theological readings: Highlight the centrality of Heaven, ghosts, and divine sanctions, treating Mohism as a moral theology.
  • Communitarian or rule-based views: Stress social coordination, shared standards, and rites, seeing Mohism as a project of establishing binding norms rather than maximizing utility alone.
  • Skeptical or contextual approaches: Warn against mapping modern categories (like “utilitarianism” or “theism”) too directly onto Mohism, advocating close attention to textual and historical context.

No single interpretation has become dominant; instead, these perspectives often coexist and cross-fertilize.

13.3 Textual Criticism and Layering

Scholars continue to debate:

  • The boundaries between early and later Mohist layers.
  • The authenticity of specific chapters and passages.
  • The extent of interpolation and corruption in the text’s transmission.

Some use linguistic and stylistic analysis to propose stratifications; others rely on doctrinal development (e.g., increasing technicality in the Canons). There is disagreement over how far such reconstructions can be pressed without over-interpreting limited data.

13.4 Global Reception and Comparative Work

In the 20th and 21st centuries, Mozi has attracted attention from philosophers, political theorists, and ethicists worldwide. Comparative work explores parallels and contrasts between Mohism and:

  • Western utilitarianism and contractualism
  • Christian and Islamic notions of universal love and divine law
  • Theories of just war and humanitarian intervention
  • Development ethics and global justice

Some scholars celebrate Mohism as an overlooked resource for global ethics; others caution against using it primarily as a mirror for modern concerns. The growing body of translations and secondary literature continues to expand the range of interpretations and applications.

14. Comparative Perspectives: Mozi and Global Ethics

14.1 Mohism and Utilitarianism

Comparisons between Mohism and utilitarianism focus on shared emphases:

  • Impartial consideration of everyone’s welfare.
  • Evaluation of actions and institutions by their consequences.
  • Advocacy of policies that increase overall benefit and reduce harm.

Differences include:

AspectMohismUtilitarianism (typical forms)
Metaphysical groundingHeaven’s will, sage-kings, and tradition.Often secular, rooted in rational or empirical arguments.
Scope of concernAll people under Heaven, sometimes including spirits.All sentient beings or persons, depending on theory.
StyleMixture of religious, historical, and practical appeals.Primarily philosophical or analytical.

Some scholars describe Mohism as a form of religiously grounded, rule-sensitive consequentialism, while others resist assimilating it to any single Western category.

14.2 Universalism and Partiality in Cross-Cultural Perspective

Mohist impartial concern is often discussed alongside:

  • Christian agape and the command to love one’s neighbor as oneself.
  • Buddhist and Jain ideals of compassion for all sentient beings.
  • Stoic cosmopolitanism and Kantian impartial respect.

Similarities include the attempt to transcend narrow loyalty to kin or tribe. Yet Mohism situates impartiality primarily in social policy and practical treatment, rather than inner spiritual transformation or metaphysical equality of persons. Comparative studies highlight both convergences in ethical impulse and divergences in underlying motivations and methods.

14.3 War, Peace, and Just War Theory

Mozi’s condemnation of offensive war invites comparison with:

  • Christian and Islamic just war traditions.
  • Modern international law’s restrictions on aggressive warfare.
  • Pacifist movements that reject violence entirely.

Mohism resembles just war theory in distinguishing offensive from defensive war and in emphasizing proportionality of harms. However, its rationale is grounded in benefit to the world and Heaven’s will rather than rights discourse. Some authors treat Mozi as an early advocate of humanitarian limits on state violence; others note that Mohists do not reject all uses of force and actively develop defensive technologies.

14.4 Global Justice, Development, and Environmental Ethics

Contemporary ethicists have connected Mohist ideas with debates on global justice and development:

  • Focus on securing basic material needs for all aligns with concerns about global poverty.
  • Critiques of luxury and waste resonate with discussions of inequality and sustainable consumption.
  • Emphasis on public standards and accountability parallels calls for transparent global governance.

Applications to environmental ethics are more speculative: some argue that Mohist concern for long-term, collective benefit could justify environmental stewardship; others caution that the text is primarily anthropocentric and does not explicitly address non-human nature.

Overall, comparative work uses Mozi to broaden the range of ethical models considered in global philosophy, while also exposing the limits of straightforward equivalences between classical Chinese and modern Western categories.

15. Legacy and Historical Significance

15.1 Decline as a School and Later Reception in China

By the early Han dynasty, Mohism had declined as an organized movement. Explanations include:

  • Competition from Confucianism, which gained state backing and presented a more elaborate ritual culture.
  • Overlap with emerging Legalist techniques, which may have absorbed some Mohist institutional ideas while discarding their religious and egalitarian elements.
  • Possible difficulties sustaining a quasi-military, rigorously ascetic community.

Despite institutional decline, Mohist ideas persisted:

  • Legalist and Confucian texts engage with Mohist arguments, indicating continued influence.
  • Later thinkers occasionally appeal to impartial concern and meritocratic appointment, even when not identifying as Mohists.
  • The Mozi text continued to circulate, though with less commentary and prestige than Confucian classics.

15.2 Modern Revival and Intellectual Impact

From the late 19th century onward, Chinese reformers and scholars rediscovered Mozi as a resource for modernization:

  • Reformers such as Liang Qichao praised Mohism’s egalitarianism, utilitarian orientation, and critique of hereditary privilege.
  • May Fourth intellectuals sometimes contrasted “scientific,” practical Mohism with what they saw as ritualistic Confucianism.
  • Marxist interpretations highlighted Mohism’s concern for common people and critique of aristocratic luxury, though assessments varied on its class character.

In the later 20th and 21st centuries, both Chinese and international philosophers have drawn on Mohist themes in discussions of consequentialism, humanitarianism, and welfare-oriented governance.

15.3 Place in the History of Philosophy

Mozi and Mohism are now widely recognized as:

  • A major alternative to the Confucian mainstream in classical Chinese thought.
  • A central source for the development of Chinese reflection on standards, argumentation, and semantics, especially through the Later Mohist Canons.
  • One of the earliest recorded attempts to systematize a broadly impartial, outcome-oriented ethic at the level of both personal conduct and state policy.

Historians of philosophy frequently include Mozi in comparative narratives alongside Plato, Aristotle, and early Indian thinkers, noting that:

DimensionMohist significance
EthicsEarly articulation of impartial, welfare-focused morality.
Political theoryAdvocacy of meritocratic, frugal, and peace-oriented governance.
Philosophy of religionIntegration of a moral Heaven and spiritual sanctions with social ethics.
Logic and epistemologyDevelopment of standards, definitions, and analyses of disputation.

While debate continues about how best to interpret and apply Mohist ideas, there is broad agreement that Mozi represents one of the most distinctive and systematic voices in early Chinese philosophy, with enduring relevance for contemporary discussions of ethics, politics, and religion.

Study Guide

The biography assumes some familiarity with basic philosophical and historical concepts and introduces technical Mohist terms (fa, jian’ai, ming–shi, bian). It is accessible to motivated beginners but will be most comfortable for readers who have already encountered at least one other classical Chinese thinker.

Prerequisites
Required Knowledge
  • Basic outline of ancient Chinese history (Zhou, Spring and Autumn, Warring States)Mozi’s life and ideas are responses to the political fragmentation and warfare of the Warring States period; knowing the basic chronology and main states clarifies his anti-war and meritocratic proposals.
  • General idea of what a philosophical “school” isUnderstanding that Mohism, Confucianism, and Legalism function as competing schools of thought helps make sense of the polemics and comparisons throughout the article.
  • Introductory ethics concepts (e.g., consequentialism vs. rule/role-based ethics)Many interpretations of Mozi frame him as a consequentialist; knowing this basic vocabulary helps you follow debates about ‘benefit to the world’ and impartial concern.
  • Very basic religious studies concepts (heaven, divine command, ritual)Mozi grounds norms in Heaven’s will and discusses ghosts, spirits, and ritual; basic familiarity with how religions use divine authority and ritual will help you see what is distinctive in Mohist religion.
Recommended Prior Reading
  • ConfuciusMozi is portrayed as a critic and rival of early Confucianism; knowing Confucius’s emphasis on ritual, graded love, and hierarchy makes Mohist critiques of ritual, music, and partiality much clearer.

Key Concepts to Master

Mohism (墨家, Mòjiā)

A classical Chinese philosophical movement founded by Mozi that advocates impartial concern, meritocratic government, frugality, opposition to offensive war, and reliance on objective standards (fa).

Why essential: The biography describes not only Mozi as an individual but also the community, doctrines, and later developments of Mohism; understanding Mohism as a school prevents you from reducing everything to a single person’s views.

Jian’ai (兼爱, impartial concern / universal love)

Mozi’s ethical doctrine that one should care for others’ families and states as one’s own, rejecting harmful partiality and extending concern to all under Heaven.

Why essential: This is the core of Mohist ethics and underpins Mozi’s critiques of war, nepotism, and kin-centered morality; many interpretive debates (e.g., with Confucian graded love, with utilitarianism) turn on how you understand jian’ai.

Li tianxia (利天下, benefit the world under Heaven)

A Mohist evaluative standard that judges doctrines, policies, and practices by whether they bring overall benefit—wealth, order, and security—to all people under Heaven.

Why essential: This concept anchors interpretations of Mozi as a consequentialist; it links ethics, politics, and even religious claims to a single measure of overall social welfare.

Fa (法, standards / models)

Publicly accessible rules, models, or criteria used to test claims and guide action, likened to tools such as a carpenter’s square or compass.

Why essential: Fa connects Mohist epistemology, political administration, and logic; it explains how Mohists think we can move from vague values like ‘benefit’ to concrete, checkable policies and judgments.

Ming–shi (名实, names and actualities)

The relation between linguistic labels (names) and the things or facts they refer to (actualities), a central topic in Later Mohist analyses of correct naming and argument.

Why essential: Appreciating Mohist concern for ming–shi helps you see why the school invests so much in precise terminology, disputation, and standards, and why they are significant in the history of Chinese logic and semantics.

Fei Gong (非攻, against offensive war)

Mozi’s doctrine that aggressive warfare is morally wrong and socially disastrous, though defensive war aimed at protecting the innocent is permissible and even obligatory.

Why essential: Fei Gong shows how Mohist impartial concern translates into concrete political stances; it connects Mozi to just war theory and makes sense of the quasi-military organization of the Mohist community.

Tian (天, Heaven) and the Will of Heaven

An intentional, morally concerned cosmic power that desires righteousness, hates unrighteousness, and rewards or punishes human actions accordingly.

Why essential: Heaven’s will is one of Mozi’s main justifications for his ethical and political program; debates over whether Mohism is primarily religious, consequentialist, or both hinge on how you read references to tian.

Bian (辩, disputation) and Later Mohist logic

Structured argument and analysis developed especially by Later Mohists, including distinctions about names, inference, and standards, preserved in the Canons and Explanations.

Why essential: Recognizing the role of bian and the Later Mohist Canons prevents you from viewing Mohism as only ‘practical ethics’; it highlights their contribution to early Chinese philosophy of language and reasoning.

Common Misconceptions
Misconception 1

Mozi taught a purely emotional ‘love everyone equally’ that abolishes family ties.

Correction

Mozi attacks harmful partiality in practice, not the existence of special relationships. Jian’ai is primarily about extending concern and fair treatment in policy and behavior, not erasing all role-based obligations or emotions.

Source of confusion: The phrase ‘universal love’ and Confucian critiques make it easy to assume Mozi wanted to flatten all affection; the article clarifies that many scholars prefer ‘impartial concern’ to avoid this overstatement.

Misconception 2

Mohism is simply an ancient version of modern utilitarianism.

Correction

Mohism is strongly consequentialist but also grounds norms in Heaven’s will, sage-kings, and tradition; it combines outcome-based reasoning with religious and historical appeals rather than being a purely secular, utility-maximizing theory.

Source of confusion: Shared themes like impartiality and benefit encourage equating Mohism with utilitarianism, but the article stresses important differences in metaphysics, justification, and style of argument.

Misconception 3

The Mozi text reflects a single authorial voice and can be read as Mozi’s own words throughout.

Correction

The received Mozi is a composite compiled over generations, with early doctrinal essays, middle religious chapters, and later technical Canons; many chapters were likely written or edited by disciples and successors.

Source of confusion: The text’s traditional attribution to ‘Mozi’ and limited biographical data can obscure the extensive internal evidence for layering and redaction discussed in Sections 3 and 4.

Misconception 4

Mohists were straightforward pacifists who rejected all forms of warfare.

Correction

Mohists condemn offensive war but actively support and even staff defensive warfare, including fortification and military engineering, viewing defense of the innocent as ethically required.

Source of confusion: The strong rhetoric ‘against offensive war’ can be mistaken for a rejection of all violence; the biography emphasizes their involvement in justifiable defense.

Misconception 5

Mohism is entirely rationalistic and dismisses religious belief as superstition.

Correction

Mohism makes extensive use of Heaven, ghosts, and spirits as real or at least normatively significant; these religious elements are integrated into its ethical and political program, not rejected.

Source of confusion: Modern praise for Mohism’s ‘practical’ or ‘scientific’ spirit can lead readers to downplay the religious chapters on Heaven’s will and ghostly sanctions that the article highlights.

Discussion Questions
Q1beginner

How does Mozi’s doctrine of jian’ai (impartial concern) aim to solve the social and political problems of the Warring States period?

Hints: Look at Section 6.1–6.3 and the quote about ‘regarding others’ states as one’s own.’ Ask: Which problems does Mozi attribute to partiality? How would extending concern change rulers’ and commoners’ behavior?

Q2intermediate

In what ways is Mozi’s appeal to ‘benefit the world under Heaven’ (li tianxia) similar to and different from modern consequentialist ethics?

Hints: Use the table in Section 6.3 and the comparative discussion in Sections 13 and 14. Consider: What counts as ‘benefit’? How does Heaven’s will, tradition, and the sage-kings factor into justification alongside consequences?

Q3intermediate

Is Mohist meritocracy (shangxian) compatible with the strong hierarchical obedience emphasized in the shangtong (‘exalting unity’) chapters?

Hints: Read Section 7.1–7.3. Ask: Who chooses the ‘worthy,’ and by what standards? Does shangtong risk empowering bad rulers, or are rulers constrained by Heaven’s will and fa? How might Mohists respond to the charge of proto-authoritarianism?

Q4advanced

How do Mozi’s religious claims about Heaven, ghosts, and spirits interact with his empirical and outcome-based tests for doctrines?

Hints: Consult Sections 9 and 12, plus 10.1. Consider whether appeals to Heaven and spirits are independent sources of normativity or are justified by their social effects. Is Mohist epistemology best read as theistic, pragmatic, or both?

Q5advanced

Compare Mohist critiques of Confucian ritual, music, and funerals with Confucian defenses of these practices. What fundamental disagreements about the role of culture and emotion in ethics emerge?

Hints: Use Section 11.1–11.2 and bring in what you know about Confucianism. Think about opportunity cost vs. cultivation of feeling, and about whether some practices have value beyond measurable ‘benefit.’

Q6advanced

Do the Later Mohist Canons and discussions of ming–shi (names and actualities) represent a natural development of Mozi’s original concerns, or a shift toward a different kind of philosophical project?

Hints: See Sections 4.1, 5.2, and 10.3–10.4. Identify continuities (fa, standards, correct naming) and possible discontinuities (technicality, abstraction). How might institutional changes in the Mohist community have driven this evolution?

Q7intermediate

To what extent can Mozi’s anti-war doctrine (Fei Gong) be understood as an early version of just war theory?

Hints: Use Section 8.2 and 14.3. Ask: How does Mozi distinguish offensive from defensive war? What criteria does he implicitly set for legitimate warfare? Compare these to typical just war conditions like just cause and proportionality.
