Antonia Lolordo presents an original interpretation of John Locke's conception of moral agency-one that has implications both for his metaphysics and for the foundations of his political theory. Locke denies that species boundaries exist independently of human convention, holds that the human mind may be either an immaterial substance or a material one to which God has superadded the power of thought, and insists that animals possess the ability to perceive, will, and even reason-indeed, in some cases to reason better than humans. Thus, he eliminates any sharp distinction between humans and the rest of the animal kingdom. However, in his ethical and political work Locke assumes that there is a sharp distinction between moral agents and other beings. He thus needs to be able to delineate the set of moral agents precisely, without relying on the sort of metaphysical and physical facts his predecessors appealed to. Lolordo argues that for Locke, to be a moral agent is simply to be free, rational, and a person. Interpreting the Lockean metaphysics of moral agency in this way helps us to understand both Locke's over-arching philosophical project and the details of his accounts of liberty, personhood, and rationality.

What is a person? Why do we count certain beings as persons and others not? How is the concept of a person distinct from the concept of a human being, or from the concept of the self? When and why did the concept of a person come into existence? What is the relationship between moral personhood and metaphysical personhood? How has their relationship changed over the last two millennia? This volume presents a genealogy of the concept of a person. It demonstrates how personhood-like the other central concepts of philosophy, law, and everyday life-has gained its significance not through definition but through the accretion of layers of meaning over centuries. We can only fully understand the concept by knowing its history. Essays show further how the concept of a person has five main strands: persons are particulars, roles, entities with special moral significance, rational beings, and selves. Thus, to count someone or something as a person is simultaneously to describe it-as a particular, a role, a rational being, and a self-and to prescribe certain norms concerning how it may act and how others may act towards it. A group of distinguished thinkers and philosophers here untangle these and other insights about personhood, asking us to reconsider our most fundamental assumptions of the self.

Debates in Modern Philosophy: Essential Readings and Contemporary Responses provides an in-depth, engaging introduction to important issues in modern philosophy. It presents 13 key interpretive debates to students, and ranges in coverage from Descartes' Meditations to Kant's Critique of Pure Reason.

Debates include:

• Did Descartes have a developed and consistent view about how the mind interacts with the body?
• Was Leibniz an idealist, or did he believe in corporeal substances?
• What is Locke's theory of personal identity?
• Could there be a Berkeleian metaphysics without God?
• Did Hume believe in causal powers?
• What is Kant's transcendental idealism?

Each of the thirteen debates consists of a well known article or book chapter from a living philosopher, followed by a new response from a different scholar, specially commissioned for this volume. Every debate is prefaced by an introduction written for those coming upon the debates for the first time and followed by an annotated list for further reading. The volume starts with an introduction that explains the importance and relevance of the modern period and its key debates to philosophy and ends with a glossary that covers terms from both the modern period and the study of the history of philosophy in general.

Debates in Modern Philosophy will help students evaluate different interpretations of key texts from modern philosophy, and provide a model for constructing their own positions in these debates.

This is the first modern edition of the works of Lady Mary Shepherd, one of the most important women philosophers of the early modern period. Shepherd has been widely neglected in the history of philosophy, but her work engaged with the dominant philosophers of the time - among them Hume, Berkeley, and Reid. In particular, her 1827 volume Essays on the Perception of an External Universe outlines a theory of causation, perception, and knowledge which Shepherd presents as an alternative to what she sees as the mistaken views of Berkeley and Hume. What she ultimately presents is an original and systematic metaphysics and epistemology. Shepherd's Essays consists of two parts. The first is a theory of perception and knowledge of the external world, which is designed to rebut idealism and skepticism about the external world and show that our ordinary beliefs are based on reason. The second is a collection of essays on topics in metaphysics and epistemology, including the immateriality and eternity of the mind, the relationship between mind and body, the possibility of miracles, the association of ideas, the relationship between physical and mathematical reasoning, and the epistemology of testimony. Antonia LoLordo's edition of Shepherd's Essays includes scholarly notes throughout the text that provide historical and philosophical context and expand on the major concepts of Shepherd's system. Her extensive introduction to Shepherd's life and works surveys some of the major points of Shepherd's system, points out directions for future research, and offers guidance for readers planning to teach her work in their courses. This volume is an invaluable primary resource for scholars, graduate students, and undergraduates interested in metaphysics, epistemology, and early modern philosophy.

There has recently been a resurgence of interest in the early nineteenth century Scottish philosopher Mary Shepherd. This Element is intended to provide an overview of Shepherd's system, including her views on the following wide range of topics: causation, induction, knowledge of the external world, matter, life, animal cognition, the relationship between mind and body, the immortality of the soul, the existence of God, miracles, and the nature of divine creation. The author also provides an overview of relevant secondary literature and argues for their own interpretation of Shepherd's metaphysics.

This book offers a comprehensive treatment of the philosophical system of the seventeenth-century philosopher Pierre Gassendi. Gassendi's importance is widely recognized and is essential for understanding early modern philosophers and scientists such as Locke, Leibniz and Newton. Offering a systematic overview of his contributions, LoLordo situates Gassendi's views within the context of sixteenth- and early seventeenth-century natural philosophy as represented by a variety of intellectual traditions, including scholastic Aristotelianism, Renaissance Neo-Platonism, and the emerging mechanical philosophy. LoLordo's work will be essential reading for historians of early modern philosophy and science.
