Manifest Activity presents and critically examines Thomas Reid's doctrines about the model of human power, the will, our capacities for purposeful conduct, and the place of our agency in the natural world. Reid is one of the most important philosophers of the 18th century, but hitherto under-appreciated; through the reconstruction of his arguments, many of which have never before been discussed, Gideon Yaffe demonstrates that Reid's simple prose and direct style belie the complexity of the views he advocates and the subtlety of the reasons he offers in their favour. For Reid, contrary to the view of many of his predecessors, it is simply manifest that we are active with respect to our behaviours; it is manifest, he thinks, that our actions are not merely remote products of forces that lie outside of our control. Reid holds, instead, that actions are all and only those events that spring from active power, and he produces insightful and imaginative arguments for the claim that only a creature with a mind is capable of having active power. He believes that only human beings, and creatures 'above us', are capable of directing events towards ends, of endowing them with purpose or direction, the distinctive feature of action. However, he also holds that all events, and not merely human actions, are products of active power, power possessed either by human beings or by God. This collection of theses leads Reid to the view that human behaviour and the progress of nature are both essentially teleological. Patterns in nature are the products of laws of which God is the author; patterns in human conduct are the products of character and the laws that individuals set for themselves. Manifest Activity examines Reid's arguments for this view and the view's implications for the nature of character, motivation, and the special kind of causation involved in the production of human behaviour. Yaffe's assessment will greatly profit anyone working on current theories of action and free will, as well as historians of ideas.

Gideon Yaffe presents a ground-breaking work which demonstrates the importance of philosophy of action for the law. Many people are serving sentences not for completing crimes, but for trying to. So the law governing attempted crimes is of practical as well as theoretical importance. Questions arising in the adjudication of attempts intersect with questions in the philosophy of action, such as what intention a person must have, if any, and what a person must do, if anything, to be trying to act. Yaffe offers solutions to the difficult problems courts face in the adjudication of attempted crimes. He argues that the problems courts face admit of principled solution through reflection either on what it is to try to do something; or on what evidence is required for someone to be shown to have tried to do something; or on what sentence for an attempt is fair given the close relation between attempts and completions. The book argues that to try to do something is to be committed by one's intention to each of the components of success and to be guided by those commitments. Recognizing the implications of this simple and plausible position helps us to identify principled grounds on which the courts ought to distinguish between defendants charged with attempted crimes.

Michael Bratman's work has been unusually influential, with significance in disciplines as diverse as philosophy, computer science, law, and primatology. This is a collection of critical essays by some of contemporary philosophy's most distinguished figures, including Margaret Gilbert, Richard Holton, Christine Korsgaard, Alfred Mele, Elijah Milgram, Kieran Setiya, Geoffrey Sayre-McCord, Scott Shapiro, Michael Smith, J. David Velleman, R. Jay Wallace. It also contains an introduction by the editors, situating Bratman's work and its broader significance. The essays in this volume engage with ideas and themes prominent in Bratman's work. The volume also includes a lengthy reply by Bratman that breaks new ground and deepens our understanding of the nature of action, rationality, and social agency.

Contemporary Perspectives on Early Modern Philosophy is a collection of essays dedicated to Vere Chappell, one of the most respected scholars in the field of early modern philosophy. Seventeen distinguished scholars have contributed essays to this collection on topics including dualism, identity and essence, causation, theodicy, free will, perception, abstraction, and the moral law.

Why be lenient towards children who commit crimes? Reflection on the grounds for such leniency is the entry point into the development, in this book, of a theory of the nature of criminal responsibility and desert of punishment for crime. Gideon Yaffe argues that child criminals are owed lesser punishments than adults thanks not to their psychological, behavioural, or neural immaturity but, instead, because they are denied the vote. This conclusion is reached through accounts of the nature of criminal culpability, desert for wrongdoing, strength of legal reasons, and what it is to have a say over the law. The centrepiece of this discussion is the theory of criminal culpability. To be criminally culpable is for one's criminal act to manifest a failure to grant sufficient weight to the legal reasons to refrain. The stronger the legal reasons, then, the greater the criminal culpability. Those who lack a say over the law, it is argued, have weaker legal reasons to refrain from crime than those who have a say. They are therefore reduced in criminal culpability and deserve lesser punishment for their crimes. Children are owed leniency, then, because of the political meaning of age rather than because of its psychological meaning. This position has implications for criminal justice policy, with respect to, among other things, the interrogation of children suspected of crimes and the enfranchisement of adult felons.

This is the first comprehensive interpretation of John Locke's solution to one of philosophy's most enduring problems: free will and the nature of human agency. Many assume that Locke defines freedom as merely the dependency of conduct on our wills. And much contemporary philosophical literature on free agency regards freedom as a form of self-expression in action. Here, Gideon Yaffe shows us that Locke conceived free agency not just as the freedom to express oneself, but as including also the freedom to transcend oneself and act in accordance with "the good." For Locke, exercising liberty involves making choices guided by what is good, valuable, and important. Thus, Locke's view is part of a tradition that finds freedom in the imitation of God's agency. Locke's free agent is the ideal agent.

Yaffe also examines Locke's understanding of volition and voluntary action. For Locke, choices always involve self-consciousness. The kind of self-consciousness to which Locke appeals is intertwined with his conception of personal identity. And it is precisely this connection between the will and personal identity that reveals the special sense in which our voluntary actions can be attributed to us and the special sense in which we are active with respect to them. Deftly written and tightly focused, "Liberty Worth the Name" will find readers far beyond Locke studies and early modern British philosophy, including scholars interested in free will, action theory, and ethics.
