John Martin Fischer
John Martin Fischer (b. 1952) is a prominent American analytic philosopher best known for reshaping contemporary debates about free will, moral responsibility, and the meaning of life. Educated at Stanford University and Cornell University, and long based at the University of California, Riverside, Fischer argues that moral responsibility does not require the sort of open alternatives traditionally demanded by libertarian theories of free will. His position, known as semi-compatibilism, holds that even if determinism is true and metaphysical freedom in the robust, alternative-possibilities sense fails, agents can still be morally responsible so long as they exhibit the right kind of guidance control over their actions. This framework has deeply influenced ethics, legal theory, and philosophical theology by providing a sophisticated compatibilist-friendly account of blame and praise. Beyond free will, Fischer has significantly contributed to the philosophy of death and the afterlife. He has investigated why death is bad, how fear of death might be rational or irrational, and whether immortality would be desirable. Through both scholarly monographs and public-facing projects like the Templeton-funded ‘Immortality Project’, Fischer has helped connect abstract metaphysical questions to widely shared human concerns about responsibility, punishment, death, and meaning.

John Martin Fischer’s central thesis is that moral responsibility is compatible with causal determinism even if determinism rules out robust alternative possibilities; what matters for responsibility is not an agent’s freedom to do otherwise, but the kind of guidance control the agent exercises over her actions—specifically, whether her conduct issues from a moderately reasons-responsive mechanism that she owns, within an appropriate actual causal sequence. This semi-compatibilist framework decouples responsibility from metaphysical libertarian freedom while preserving the intelligibility of moral praise, blame, and reactive attitudes, and it is complemented by a nuanced view of death and the afterlife that treats mortality as typically a serious harm but not necessarily an irrational object of fear, and that questions both the desirability and coherence of many conceptions of immortality. Overall, Fischer’s system integrates metaphysics, moral psychology, and existential reflection to defend a compatibilist-friendly understanding of agency and a sober, humane approach to the fact of death.

Semi-compatibilism is the view that moral responsibility is compatible with causal determinism, regardless of whether free will is compatible with determinism.— John Martin Fischer, The Metaphysics of Free Will: An Essay on Control (Oxford University Press, 1994).
Fischer introduces and defines semi-compatibilism, marking his distinctive position in the free will debate by separating questions about responsibility from questions about freedom to do otherwise.
It is guidance control, not regulative control, that is crucial for moral responsibility.— John Martin Fischer and Mark Ravizza, Responsibility and Control: A Theory of Moral Responsibility (Cambridge University Press, 1998).
In collaboration with Mark Ravizza, Fischer emphasizes that what matters for responsibility is the agent’s control over the actual causal sequence, not access to alternative possibilities.
An agent acts freely and is morally responsible when her behavior issues from a moderately reasons-responsive mechanism that she owns.— John Martin Fischer and Mark Ravizza, Responsibility and Control: A Theory of Moral Responsibility (Cambridge University Press, 1998).
Fischer and Ravizza summarize their reasons-responsive account of guidance control, which has become a standard compatibilist model of responsible agency.
Death is typically a very serious misfortune because of the good things it deprives us of, even if we do not experience it as such.— John Martin Fischer, Our Stories: Essays on Life, Death, and Free Will (Oxford University Press, 2009).
Fischer articulates a deprivationist view of the badness of death, aligning with but also refining Epicurean and post-Epicurean discussions about whether and how death can harm us.
Immortality might not be an unalloyed good; an endlessly extended life could become intolerably boring or alienating from our deepest projects and values.— John Martin Fischer, Death, Immortality, and Meaning in Life (Oxford University Press, 2019).
Here Fischer engages with the Makropulos-style argument about immortality, suggesting that some forms of eternal life could undermine, rather than enhance, meaning in life.
Formative Education and Early Analytic Training (1970–1978)
During his undergraduate years at Stanford and graduate work at Cornell, Fischer absorbed the methods of analytic philosophy, focusing on metaphysics and philosophy of action. Exposure to debates about determinism, agency, and moral responsibility during this period oriented him toward questions of control, alternative possibilities, and the structure of responsible agency.
Development of Semi-Compatibilism (late 1970s–mid 1990s)
In the early decades of his career, Fischer deepened and defended what would become known as semi-compatibilism. Influenced by Frankfurt-style counterexamples to the Principle of Alternate Possibilities, he argued that moral responsibility hinges on the quality of the actual causal sequence leading to an action, rather than on the presence of robust alternative possibilities.
Refinement of Guidance Control and Responsibility (mid 1990s–2000s)
With works like *The Metaphysics of Free Will* and *Responsibility and Control* (with Mark Ravizza), Fischer refined the concepts of regulative and guidance control, distinguishing between freedom to do otherwise and the capacities for reasons-responsiveness. He developed detailed accounts of how agents can be responsible under determinism, responding to libertarian and skeptic critics.
Engagement with Death, Immortality, and Meaning (2000s–2010s)
Fischer extended his focus to the philosophy of death and meaning in life, examining whether death harms us, how we should regard our mortality, and whether an afterlife or immortality would be meaningful or tedious. His leadership of ‘The Immortality Project’ integrated philosophical analysis with empirical research on near-death experiences and religious conceptions of the afterlife.
Public Philosophy and Interdisciplinary Influence (2010s–present)
In recent years, Fischer has become a central figure not only in technical debates among philosophers but also in public discussions about punishment, legal responsibility, and existential anxiety about death. By framing complex issues in accessible terms, he has influenced legal theorists, theologians, psychologists, and broader cultural conversations about agency and mortality.
1. Introduction
John Martin Fischer (b. 1952) is a leading figure in contemporary analytic philosophy, best known for his work on free will, moral responsibility, and the philosophy of death. He is especially associated with semi-compatibilism, the view that moral responsibility is compatible with causal determinism even if the sort of free will involving robust alternative possibilities is not.
Fischer’s contributions center on two clusters of issues. First, in the philosophy of action and moral psychology, he offers a detailed account of the kind of control required for responsibility, developing concepts such as guidance control, reasons-responsiveness, and actual-sequence theories of agency. Second, in the philosophy of death and the meaning of life, he explores why death may be a harm, when fear of death might be rational, and whether various forms of immortality or afterlife would be meaningful or desirable.
His work is situated within late 20th– and early 21st‑century Anglophone analytic philosophy, drawing on and responding to figures such as Harry Frankfurt, Peter van Inwagen, P. F. Strawson, and Bernard Williams. It has influenced debates in ethics, criminal law, and philosophical theology, and has been disseminated both through single‑authored monographs and through widely used edited collections that map the landscape of positions on free will and responsibility.
Fischer’s writings combine detailed argument with an emphasis on ordinary moral practices, such as blame, resentment, and forgiveness, and on common existential concerns about mortality. This dual focus makes his work central to technical philosophical discussion while also being frequently cited in more interdisciplinary and public-facing conversations about agency, punishment, and the significance of death.
2. Life and Historical Context
John Martin Fischer was born on 26 December 1952 in Cleveland, Ohio, and received his undergraduate degree in philosophy from Stanford University in 1974, followed by a Ph.D. from Cornell University in 1978. After short early appointments, he joined the faculty at the University of California, Riverside in 1981, which has remained his primary academic base and where he helped build a prominent center for the study of free will and moral responsibility.
His formative years coincided with a period in analytic philosophy when debates about determinism, agency, and moral responsibility were reshaped by Harry Frankfurt’s challenge to the Principle of Alternate Possibilities and by renewed interest in P. F. Strawson’s account of the “reactive attitudes.” These developments provided much of the background against which Fischer formulated his own semi-compatibilist view.
The broader intellectual environment of the 1980s–2000s also included the rise of naturalistic approaches in metaphysics and moral psychology, increased attention to legal responsibility and punishment, and a revival of systematic work on death and meaning in life. Fischer’s later engagement with death and immortality emerged partly within this renewed interest and partly in dialogue with work by philosophers such as Thomas Nagel, Derek Parfit, and Bernard Williams.
A simplified timeline situating Fischer within these currents is:
| Year/Period | Context |
|---|---|
| 1960s–1970s | Frankfurt-style cases and critiques of PAP gain prominence. |
| 1970s–1980s | Fischer’s education at Stanford and Cornell; early career during the consolidation of analytic metaphysics and action theory. |
| 1990s | Publication of The Metaphysics of Free Will amid intense compatibilism–libertarianism debates. |
| 2000s–2010s | Expansion into death, immortality, and meaning; growth of interdisciplinary work on responsibility and law. |
| 2012–2015 | Leadership of The Immortality Project, reflecting wider interest in empirically informed philosophy of religion and death. |
3. Intellectual Development
Fischer’s intellectual development can be understood as unfolding through several overlapping phases, each shaped by evolving debates in analytic philosophy.
Early Formation and Focus on Free Will
During his studies at Stanford and Cornell in the 1970s, Fischer engaged with contemporary work on determinism, agency, and moral responsibility. Influenced by the emerging literature on Frankfurt-style counterexamples, he became concerned with whether responsibility truly requires the ability to do otherwise. His early articles (1980s–early 1990s) scrutinize the Principle of Alternate Possibilities (PAP) and explore how agents might be responsible even when alternatives are constrained.
Articulation of Semi-Compatibilism
By the time of The Metaphysics of Free Will (1994), Fischer had developed semi-compatibilism, explicitly separating questions about the compatibility of determinism with free will from questions about its compatibility with moral responsibility. Here he introduces and refines the distinction between regulative control (tied to alternatives) and guidance control (tied to the actual sequence), moving the debate toward actual-sequence accounts.
Reasons-Responsiveness and Mechanism Ownership
In collaboration with Mark Ravizza in the 1990s, Fischer elaborated a systematic theory of moral responsibility centered on moderate reasons-responsiveness and mechanism ownership, culminating in Responsibility and Control (1998). This phase involved careful engagement with compatibilist and libertarian critics, neuroscientific challenges, and skeptical positions, and solidified his reputation as a principal architect of contemporary responsibility theory.
Expansion to Death and Meaning
From the 2000s onward, Fischer extended his focus to death, immortality, and meaning in life, initially through essays later collected in Our Stories (2009) and then in the monograph Death, Immortality, and Meaning in Life (2019). His leadership of The Immortality Project further integrated empirical research and religious studies into his thinking, marking an interdisciplinary turn while retaining the analytic style of argument that characterizes his work on free will.
4. Major Works and Editorial Projects
Fischer’s major works can be grouped into single-authored monographs and influential edited or co-authored volumes that have structured contemporary debates.
Single-Authored Monographs

| Various edited collections on free will and responsibility | Editor/co-editor | Curate key articles that define the modern discussion, including works by Frankfurt, van Inwagen, Strawson, and others. |
These works collectively articulate Fischer’s positions and also institutionalize the central questions and fault lines in contemporary discussions of free will, responsibility, and death.
5. Core Ideas on Free Will and Moral Responsibility
Fischer’s core ideas on free will and moral responsibility revolve around semi-compatibilism and his account of guidance control.
Semi-Compatibilism and Control
Semi-compatibilism maintains that even if determinism is incompatible with robust free will (understood as the ability to do otherwise), it can still be compatible with moral responsibility. The key notion is control rather than metaphysical openness of alternatives. Fischer distinguishes:
| Type of Control | Rough Characterization | Status for Responsibility |
|---|---|---|
| Regulative control | Ability to choose among genuinely open alternatives; “could have done otherwise.” | Not required, on Fischer’s view. |
| Guidance control | Control over the actual causal sequence leading to action. | Sufficient and necessary for responsibility. |
He argues that what matters is that the agent’s action issues from an appropriate mechanism in the actual world, rather than that there exist robustly accessible alternative possibilities.
Reasons-Responsiveness and Mechanism Ownership
With Mark Ravizza, Fischer analyzes guidance control as involving:
- A moderately reasons-responsive mechanism: the mechanism that issues in action must be disposed to recognize and react to sufficient reasons across a range of possible scenarios, though not perfectly.
- Mechanism ownership: the agent must have come to see that mechanism as her own through a history involving moral education, reflection, and uptake of responsibility.
“An agent acts freely and is morally responsible when her behavior issues from a moderately reasons-responsive mechanism that she owns.”
— John Martin Fischer and Mark Ravizza, Responsibility and Control
This framework supports an actual-sequence view of responsibility: assessments focus on the actual causal history, including whether the agent’s mechanism was reasons-responsive and owned, rather than on counterfactual abilities.
Fischer applies this model to cases involving manipulation, coercion, and moral luck, arguing that responsibility can persist under determinism and even when agents lack traditional alternative possibilities, provided guidance control is intact.
6. Death, Immortality, and the Meaning of Life
Fischer’s work on death and meaning examines three main questions: whether death is bad for the one who dies, whether fear of death can be rational, and whether immortality or an afterlife would enhance or undermine meaning.
The Badness of Death
Fischer develops a deprivation account: death is typically a serious misfortune because it deprives a person of future goods they would otherwise have enjoyed.
“Death is typically a very serious misfortune because of the good things it deprives us of, even if we do not experience it as such.”
— John Martin Fischer, Our Stories
He engages with Epicurean arguments that “death is nothing to us,” arguing that while we do not experience our own being dead, the loss of future goods can still ground a prudential harm. He also considers timing problems (when death harms) and comparative cases (longer vs. shorter lives).
Fear of Death
Fischer analyzes whether fear of death is irrational given its inevitability and our lack of experience of being dead. He contends that fear may be rational when it tracks the deprivation of valued projects and relationships, while also noting that excessive or misdirected fear can be problematic. He compares different attitudes—resignation, defiance, acceptance—without endorsing a single ideal.
Immortality and Afterlife
Addressing Bernard Williams’s “Makropulos case,” Fischer examines whether endless life would be intolerably boring or alienating. He suggests that under some conditions—e.g., with appropriate capacities for renewal of interests—certain forms of immortality might be meaningful, though he also emphasizes possible risks of tedium and loss of identity.
In The Immortality Project, Fischer oversaw interdisciplinary work on near-death experiences, religious conceptions of the afterlife, and psychological responses to mortality, aiming to clarify how beliefs about survival bear on ethical outlooks and life’s meaning without presupposing any particular religious doctrine.
7. Methodology and Style of Argument
Fischer’s methodology is characteristically analytic, combining careful conceptual analysis, fine-grained case construction, and close engagement with opponents’ arguments.
Use of Thought Experiments and Cases
He relies heavily on thought experiments—especially variants of Frankfurt-style cases—to probe intuitions about responsibility and alternative possibilities. These cases are often modified in detail to isolate specific features (e.g., counterfactual intervener timing, mechanism structure) and to test how robust judgments of responsibility are under variation.
Actual-Sequence Focus
Methodologically, Fischer emphasizes the actual sequence of events leading to an action. Rather than exploring a wide array of metaphysically possible alternatives, he asks what it is about the actual causal history—reasons, mechanisms, ownership conditions—that grounds responsibility. This focus informs his systematic use of counterfactual analysis of reasons-responsiveness (how mechanisms would behave under different reasons) while still treating responsibility as tied to the actual world.
Engagement with Opposing Views
Fischer’s writings carefully reconstruct rival positions—libertarian, hard incompatibilist, and skepticism about free will—and often present them in their strongest form. In works like Four Views on Free Will, he participates in structured debate formats that include replies and counter-replies, showcasing a dialogical style.
Interdisciplinary Sensitivity
While primarily a philosopher of a traditional analytic kind, Fischer incorporates findings and questions from law, psychology, neuroscience, and religious studies, especially in discussions of criminal responsibility and death. He tends to treat empirical results as constraints or prompts for conceptual clarification rather than as decisive on their own.
Expositional Style
His prose is relatively non-technical, with frequent use of everyday examples (driving, addiction, parenting) and narrative elements (“our stories”). This style is intended to connect abstract theorizing about control and death with familiar moral practices and lived experiences.
8. Influence on Law, Theology, and Public Discourse
Fischer’s theories of responsibility and death have had notable impact beyond academic philosophy, especially in law, theology, and broader public discourse.
Law and Criminal Responsibility
Legal theorists and philosophers of law have drawn on Fischer’s account of guidance control and reasons-responsiveness to analyze criminal culpability, insanity defenses, and diminished responsibility. His focus on whether an agent’s mechanism is capable of responding to reasons, and whether the agent “owns” that mechanism, has been used to clarify:
- how mental disorders or coercive environments might undermine responsibility;
- the distinction between excusing conditions and full culpability under determinism;
- the justification of blame and punishment even if alternative possibilities are absent.
His work is frequently cited in discussions of whether neuroscientific findings about brain processes threaten traditional notions of responsibility.
Theology and Philosophy of Religion
In the philosophy of religion, Fischer’s semi-compatibilism informs debates about divine foreknowledge, predestination, and moral responsibility. Some theologians use his framework to argue that responsibility can coexist with exhaustive divine foreknowledge or providence, focusing on actual-sequence control rather than libertarian free will. His writings on death and immortality also intersect with doctrinal discussions about the afterlife, resurrection, and the value of eternal life.
Public and Interdisciplinary Discourse
Through The Immortality Project and related outreach, Fischer has engaged psychologists, cognitive scientists, and religious scholars in examining attitudes toward death and belief in an afterlife. Public lectures, interviews, and popular essays have brought his ideas about fear of death, narrative identity, and meaningful immortality to wider audiences.
In policy-oriented and cultural debates, his work is sometimes invoked in discussions of:
- the fairness of retributive punishment;
- the moral status of life-extending technologies;
- how societies should address existential anxiety about mortality.
In these contexts, Fischer’s influence is primarily conceptual, providing vocabularies—such as “guidance control” or “deprivation harm”—that shape how questions are framed rather than dictating specific normative conclusions.
9. Critical Reception and Debates
Fischer’s work has generated extensive discussion, with both strong endorsements and sustained criticism across several fronts.
Semi-Compatibilism and Guidance Control
Compatibilist philosophers often treat Fischer’s semi-compatibilism and the reasons-responsiveness model as a leading version of contemporary compatibilism about responsibility. Critics, however, raise several objections:
| Issue | Critical Concerns |
|---|---|
| Dependence on Frankfurt-style cases | Some argue that Frankfurt-style counterexamples to PAP are unsuccessful or rely on illicit assumptions about counterfactuals, which would weaken the case for divorcing responsibility from alternatives. |
| Depth of control | Incompatibilists and free-will skeptics contend that reasons-responsiveness under determinism is merely “surface-level” and fails to provide the kind of deep control required for genuine desert. |
| Manipulation and history | Critics question whether Fischer’s mechanism-ownership conditions can adequately distinguish ordinary upbringing from problematic manipulation or brainwashing. |
Moral Luck and Actual-Sequence Views
Fischer’s actual-sequence focus has been praised for illuminating how causal histories matter, but it also faces worries about moral luck: if responsibility hinges on actual sequences, then differences in outcomes due to luck may threaten fairness. Some philosophers argue that Fischer’s framework either accommodates more luck than is acceptable or must be supplemented by alternative-possibilities considerations.
Death, Deprivation, and Immortality
In the philosophy of death, Fischer’s deprivation account aligns with influential views by Thomas Nagel and others, but is contested by:
- Epicurean-inspired critics, who maintain that non-experienced states cannot harm us;
- theorists who emphasize relational or narrative accounts of harm that differ from Fischer’s mainly prudential focus.
Regarding immortality, some commentators view Fischer as overly optimistic about the potential meaningfulness of endless life, arguing that even with renewed interests, problems of identity, value saturation, or alienation may remain. Others think he grants too much to Williams-style pessimism and underestimates religious or transhumanist conceptions of transformed, ever-meaningful existence.
Overall Assessment
Despite disagreements, Fischer’s work is widely seen as a central reference point. Many subsequent accounts of responsibility, punishment, and death are framed partly in response to his positions, either by refining his concepts (e.g., alternative models of reasons-responsiveness) or by developing rival theories that challenge semi-compatibilism and deprivationism directly.
10. Legacy and Historical Significance
Fischer’s legacy within contemporary philosophy is closely tied to how debates about free will, moral responsibility, and death are now structured.
Reframing the Free Will Debate
Historically, Fischer is often credited with helping to shift attention from the question “Is free will compatible with determinism?” to the more fine-grained question “Is moral responsibility compatible with determinism, regardless of free will?” This reframing, embodied in semi-compatibilism, has become a standard way of carving the conceptual terrain, influencing textbooks, anthologies, and introductory discussions.
His distinction between regulative and guidance control and his detailed model of moderate reasons-responsiveness have provided a widely discussed template for analyzing responsible agency. Later compatibilists, revisionists, and skeptics often define their own positions partly in contrast to or in refinement of Fischer’s framework.
Consolidation of Responsibility Studies
At an institutional level, Fischer’s long tenure at UC Riverside contributed to the development of that department as a major center for research on free will and responsibility. His editorial work in collections and debate volumes has played a role in canonizing key texts and organizing the main positions in the literature.
Contributions to the Philosophy of Death
In the philosophy of death and mortality, Fischer’s articulation of a nuanced deprivation view, his engagement with the rationality of fear, and his exploration of immortality have become part of the core contemporary conversation. The Immortality Project marks a historically significant moment in the interdisciplinary study of death, integrating analytic philosophy with empirical research and religious studies on an unprecedented scale.
Broader Cultural and Interdisciplinary Impact
Although primarily an academic philosopher, Fischer’s ideas have influenced discussions in law, theology, and public ethics, particularly concerning punishment, life-extending technologies, and responses to mortality. His work contributes to a broader late 20th– and early 21st‑century movement that treats questions of agency and death as areas where analytic methods can illuminate pervasive human concerns.
Within the historical narrative of analytic philosophy, Fischer is frequently classified among the most influential late‑20th‑century theorists of responsibility and among the leading contemporary voices in the philosophy of death and immortality.
