Abstract: Implicit in much contemporary philosophy is a Picture Theory of language according to which we can ‘read off’ features of the world from features of our ways of talking about the world. Predicates applying truthfully to objects, for instance, are taken to name properties of those objects possessed by every object to which the predicates apply. Such a principle might be thought to follow from a more general ‘truth-making’ requirement (truths require truth-makers) together with the idea that truth-makers entail truths. I argue that truth-making is not entailment and that the Picture Theory should be jettisoned and replaced by an attitude of ontological seriousness. Freed of constraints imposed by the Picture Theory, we are in a position to see our way through metaphysical difficulties associated with contemporary philosophy of mind. Following Locke (and C. B. Martin), I endorse a conception of properties as modes (or tropes): ways particular objects are. Modes are simultaneously qualities and powers: powerful qualities. Application of this thesis to familiar issues in the philosophy of mind yields surprising results.
