Ernie Lepore and Barry Loewer present a series of papers in which they come to terms with three views that have loomed large in philosophy for several decades: that a theory of meaning for a language is best understood as a theory of truth for that language; that thought and language are best understood together via a theory of interpretation; and that the mental is irreducible to the physical. They aim both to offer critical assessment of the views and to develop them. They show that each of these views remains of great significance for current work in philosophy of language and mind.
