Contents

Freedom of the Will is the problem of whether agents possess the capacity to choose among alternative courses of action in a manner that is not wholly determined by antecedent causes. It intersects debates in Plato, Aristotle, Saint Augustine, Thomas Aquinas and modern thinkers about moral responsibility, legal accountability, and religious doctrine. Discussions involve metaphysical claims about causation as treated by Isaac Newton, Gottfried Wilhelm Leibniz, Baruch Spinoza and Pierre-Simon Laplace and emerging empirical findings from investigators affiliated with University of Cambridge, Massachusetts Institute of Technology, Stanford University, Harvard University.

Definitions and Concepts

Philosophical definitions invoke distinctions such as compatibilism versus incompatibilism articulated by David Hume, Thomas Hobbes, and John Locke, and libertarianism defended by Roderick Chisholm and Robert Kane. Key concepts include moral responsibility discussed by Immanuel Kant and John Stuart Mill, causal determinism explored by Pierre-Simon Laplace and Arthur Schopenhauer, and agent causation advanced by Edmund Gettier--adjacent to debates from Galen Strawson. Related notions of freedom appear in the writings of Jean-Jacques Rousseau, John Rawls, and Isaiah Berlin; operational distinctions echo in work by Herbert Feigl and W. V. O. Quine.

Ancient and medieval strands trace from Plato and Aristotle to theological synthesis in Augustine of Hippo and Thomas Aquinas with scholastic debates at University of Paris. Reformation-era disputes involved Martin Luther, John Calvin, and the Council of Trent. Early modern treatments arose in correspondence among René Descartes, Blaise Pascal, Baruch Spinoza, and Gottfried Wilhelm Leibniz; empiricists such as John Locke, George Berkeley, and David Hume reframed the problem. Nineteenth-century figures including Georg Wilhelm Friedrich Hegel, Arthur Schopenhauer, Friedrich Nietzsche, and Søren Kierkegaard redirected questions toward will, agency, and existential meaning. Twentieth-century analytic and continental debates featured G. E. Moore, Ludwig Wittgenstein, Jean-Paul Sartre, Hannah Arendt, Gilbert Ryle, and Donald Davidson.

Compatibilists such as David Hume, Thomas Hobbes, Daniel Dennett, and Harry Frankfurt argue freedom coherent with causal determination; Frankfurt’s counterexamples engage Frankfurt-style literature and critique from Susan Wolf. Incompatibilists include determinists like Baruch Spinoza and libertarians such as Roderick Chisholm and Robert Kane who defend indeterministic agency. Skeptical perspectives arise in work by Galileo Galilei-influenced naturalists and in Derk Pereboom’s hard incompatibilism. Kantian constructs of autonomy and practical reason are associated with Immanuel Kant and extended by John Rawls and Jürgen Habermas; existentialist accounts by Jean-Paul Sartre and Simone de Beauvoir emphasize radical freedom.

Empirical research by laboratories at Massachusetts Institute of Technology, Max Planck Society, and University College London has informed debates with experiments like those of Benjamin Libet, later expanded by Patrick Haggard, John-Dylan Haynes, and Aaron Schurger. Cognitive models draw on work by Daniel Kahneman, Amos Tversky, Herbert A. Simon, and Antonio Damasio. Neurophilosophers including Patricia Churchland, Paul Churchland, and Thomas Metzinger connect findings to philosophical models from Jerry Fodor and Noam Chomsky. Psychological constructs influenced by William James, Sigmund Freud, Carl Jung, and contemporary researchers such as Elizabeth Loftus and Daniel Wegner complicate straightforward notions of conscious control.

Jurisprudential discourse links theories of will to doctrines at institutions like the Supreme Court of the United States, debates over mens rea in common law traditions rooted in William Blackstone, and continental codes such as the Napoleonic Code. Ethical responsibility considerations arise in deliberations by Joseph Raz, Michael Sandel, Martha Nussbaum, and Thomas Nagel. Policy debates involving United Nations instruments and national legislatures invoke scientific testimony from experts affiliated with National Institutes of Health, American Psychological Association, and Royal Society when adjudicating criminal culpability, sentencing, and neurotechnology regulation championed by bodies like the European Court of Human Rights.

Current controversies address free will in light of predictive analytics from Google, Facebook, and research at DeepMind, algorithmic governance examined by Tim Berners-Lee critics, and ethical AI frameworks proposed by Elon Musk-funded initiatives and scholars at Oxford University. Philosophical critiques engage work by Derk Pereboom, Galen Strawson, Ned Block, John Searle, and Thomas Nagel while interdisciplinary dialogues include commentators such as Steven Pinker, Sam Harris, Daniel Dennett, and Alasdair MacIntyre. Debates extend to criminal justice reform advocated by Michelle Alexander and public policy scholars like Cass Sunstein.

Theological reflections on will are central to doctrines at Vatican City, debates in Eastern Orthodox Church, and Protestant traditions shaped by Martin Luther and John Calvin. Scholastic treatments feature Thomas Aquinas, Duns Scotus, and William of Ockham while modern theologians such as Karl Barth, Paul Tillich, and Reinhold Niebuhr engage questions of divine foreknowledge and human freedom. Interfaith perspectives appear in writings from Maimonides, Ibn Sina, and Al-Ghazali, and contemporary dialogues occur at institutions like the World Council of Churches and seminaries including Yale Divinity School and Princeton Theological Seminary.
