This book is the third of a three-volume set on the innate mind. It provides an assessment of nativist thought and definitive reference point for future inquiry. Nativists have long been interested in a variety of foundational topics relating to the study of cognitive development and the historical opposition between nativism and empiricism. Among the issues here are questions about what it is for something to be innate in the first place; how innateness is related to such things as heritability, genetic information, and theories of cognitive development; the status of arguments both for and against nativism; and how best to understand the role of genes in development and inheritance. These issues are all explored in one way or another in this book. But the book also looks to the future. Alongside state-of-the-art discussions of such established nativist concerns as language, number, spatial cognition, and social cognition, this book examines nativist work in a variety of areas where detailed nativist exploration is relatively new, including cultural learning, creativity, economic choice, culture, and morality. The expansion of nativist theorizing into all these new areas shows both the power and the promise of nativist approaches, and points the way to the future.

This book develops in detail the simple idea that assertion is the expression of belief. In it the author puts forward a version of 'probabilistic semantics' which acknowledges that we are not perfectly rational, and which offers a significant advance in generality on theories of meaning couched in terms of truth conditions. It promises to challenge a number of entrenched and widespread views about the relations of language and mind. Part I presents a functionalist account of belief, worked through a modified form of decision theory. In Part II the author generates a theory of meaning in terms of 'assertibility conditions', whereby to know the meaning of an assertion is to know the belief it expresses.
