This book can be viewed as a summation of Roderick Chisholm's views on an enormous range of topics in metaphysics and epistemology.

Categorization is an essential and unavoidable instrumentality for conceptually navigating a world—indeed for being able to conceptualize a world to be navigated. Classification is a pivotal instrument for scientific systemization, featured as a basis for the philosophical understanding of reality since Aristotle, but classificatory concepts of sorts, types and natural kinds inevitably pervade our understanding of ourselves and our position in the social as well as the natural world at all levels. The authors argue that the character, purpose-, context-, and culture-relativity of categories and categorization have been widely misunderstood—that standard philosophical views are substantially correct in some respects but markedly mistaken in others. The book offers a comprehensive survey of basic principles of classification and categorization, a survey of relevant empirical work, and a multitude of illustrative examples accompanied by instructive analysis of ways and means. The work traces wide-ranging implications of the current approach for philosophical problematic and paradox in philosophy of mind, epistemology and metaphysics, philosophy of science, social philosophy and ethics.

This book presents a clear and critical view of the orthodox logical empiricist tradition, pointing the way to significant developments for the understanding of science both as research and as culture. It summarizes the present confused and highly polarized status of the orthodox philosophy of science. It exhibits clearly the fundamental metaphysical and global presuppositions and confusions that have led to this status. It provides a positive point of view from which progress can be made toward understanding science as research done by real scientists rather than science as exemplifying some prior epistemological program created by philosophers. And it leads directly to an understanding of science as a dynamic force within our society with consequences for the environment and public policy.

A Realist Theory of Science is one of the few books that have changed our understanding of the philosophy of science. In this analysis of the natural sciences, with a particular focus on the experimental process itself, Roy Bhaskar provides a definitive critique of the traditional, positivist conception of science and stakes out an alternative, realist position. Since it original publication in 1975, a movement known as 'Critical Realism', which is both intellectually diverse and international in scope, has developed on the basis of key concepts outlined in the text. The book has been hailed in many quarters as a 'Copernican Revolution' in the study of the nature of science, and the implications of its account have been far-reaching for many fields of the humanities and social sciences.

The book re-orients jurisprudence and develops an empirically informed theory of law that applies throughout history and across different societies.
