Worries about mental causation are prominent in contemporary discussions of the mind and human agency. Originally, the problem of mental causation was that of understanding how a mental substance (thought to be immaterial) could interact with a material substance, a body. Most philosophers nowadays repudiate immaterial minds, but the problem of mental causation has not gone away. Instead, focus has shifted to mental properties. How could mental properties be causally relevant to bodily behavior? How could something mental qua mental cause what it does? After looking at the traditional Problem of Interaction, we survey various versions of the property-based problem and look at proposed solutions to them.

Philosophers and non-philosophers have been attracted to the idea that the world incorporates levels of being: higher-level items – ordinary objects, artifacts, human beings – depend on, but are not in any sense reducible to, items at lower levels. I argue that the motivation for levels stems from an implicit acceptance of a Picture Theory of language according to which we can ‘read off’ features of the world from ways we describe the world. Abandonment of the Picture Theory opens the way to a ‘no levels’ conception of reality, a conception that honors anti-reductionist sentiments and preserves the status of the special sciences without the ontological baggage.

Appeals to dispositionality in explanations of phenomena in metaphysics and the philosophy of mind, require that we first agree on what we are talking about. I sketch an account of what dispositionality might be. That account will place me at odds with most current conceptions of dispositionality. My aim is not to establish a weighty ontological thesis, however, but to move the discussion ahead in two respects. First, I want to call attention to the extent to which assumptions philosophers have made about dispositionality are far from innocent. The assumptions incorporate substantive theses that, by constraining the space of acceptable answers to particular philosophical questions, have inhibited the search for answers to those questions. Second, and more positively, I hope to open up the space of possibilities by offering an alternative way of conceiving dispositionality developed by C. B. Martin

This comprehensive textbook, written by a leading author in the field, provides a survey of mainstream conceptions of the nature of mind accessible to readers with little or no background in philosophy. Included are the dualist, behaviourist, and functionalist accounts of the nature of mind, along with a critical assessment of recent trends in the subject. The problem of consciousness, widely thought to be the chief roadblock to our understanding of the mind, is addressed throughout the book and there is also material to interest those with a professional interest in the topic - philosophers, psychologists and neuroscientists - as well as the general reader. Unique features of Philosophy of Mind : * provides a comprehensive survey of basic concepts and major theories * contains many lucid examples to support ideas * cites key literature in annotated suggested reading and a full bibliography * contains a full index including the location of key terms and concepts

From an Ontological Point of View is a highly original and accessible exploration of fundamental questions about what there is. John Heil discusses such issues as whether the world includes levels of reality; the nature of objects and properties; the demands of realism; what makes things true; qualities, powers, and the relation these bear to one another. He advances an account of the fundamental constituents of the world around us, and applies this account to problems that have plagued recent work in the philosophy of mind and metaphysics (color, intentionality, and the nature of consciousness).

Common sense and philosophical tradition agree that mind makes a difference. What we do depends not only on how our bodies are put together, but also on what we think. Explaining how mind can make a difference has proved challenging, however. Some have urged that the project faces an insurmountable dilemma: either we concede that mentalistic explanations of behavior have only a pragmatic standing or we abandon our conception of the physical domain as causally autonomous. Although each option has its advocates, most theorists have sought a middle way that accommodates both the common-sense view of mind and the metaphysical conviction about the physical world. This volume presents a collection of new, specially written essays by a diverse group of philosophers, each of whom is widely known for defending a particular conception of minds and their place in nature. Contributors include Robert Audi, Lynne Rudder Baker, Tyler Burge, Donald Davidson, Fred Dretske, Ted Honderich, Jennifer Hornsby, Frank Jackson, Jaegwon Kim, Brian P. McLaughlin, Ruth Garrett Millikan, H. W. Noonan, Philip Pettit, Ernest Sosa, and Robert Van Gulick.

Consider the idea that some entities are more fundamental than others, some entities ‘ground’ other, less fundamental, entities. What is it for something to be more fundamental than another, or for something to ‘ground’ something else? This paper urges the rejection of conceptions of grounding and fundamentality according to which reality has a hierarchical structure in which higher-level entities are taken to be distinct from but metaphysically dependent on more fundamental lower-level entities. Truthmaking is offered as an apt replacement for at least some of the many applications of grounding.

In recent work on truth and truthmaking, D. M. Armstrong has defended a version of 'truthmaker necessitarianism', the doctrine that truths necessitate truthmakers. Truthmaker necessitarianism, he contends, requires the postulation of 'totality facts', which serve as ingredients of truthmakers for general truths and negative truths, and propositions, which function as the fundamental truth bearers. I argue that neither totality facts nor propositions need figure in an account of truthmaking, and suggest that both are artifacts stemming, albeit in different ways, from an ontologically shady 'linguisticizing' tendency to conflate features of descriptions and features of what is described.

What are properties? Examples are easy. Consider a particular billiard ball. The ball is red, spherical, and has a definite mass. The ball's redness, sphericity, and mass are properties: properties of the ball. Putting it this way invites a distinction between the ball, a bearer of properties, and the ball's properties. Some philosophers deny that there are properties. To say that the ball is red or spherical, for instance, is just to say that the predicates "is red" and "is spherical" apply truly to the ball. But it is hard not to think that "is red" applies truly to the ball, if it does, because the ball is a particular way, the red way; and "is spherical" applies to the ball because it is a particular way, the spherical way; and the ways in question are distinct ways the ball is. Ways the ball is are, or appear to be, properties of the ball.

Three matchsticks could be arranged on a table so as to form a triangle. Were you to place a lump of sugar into a cup of hot tea it would dissolve. You might never have been born. Such assertions express modal judgements and, as we suppose, truths about the universe. But if modal judgements can be true, what features of the universe make them true? Thanks largely to the efforts of David Lewis, philosophers nowadays find it natural to appeal to alternative worlds to explicate modality. Something is possible if it occurs in at least one alternative world. A subjunctive conditional is true if, in the ‘nearest’ worlds in which its antecedent is true, its consequent is true. This paper includes a discussion of Lewis's ‘Humean’ ontology, the role alternative worlds play in Lewis's account of modality, and an Aristotelian alternative.
