A distinguished group of scholars met at the State University of New York at Buffalo to share their thoughts on the nature of humans as rational animals. The result is this compelling collection of essays and commentaries titled "Naturalism and Rationality". We are affected by all sorts of stimuli that influence our beliefs and actions. How does our understanding of what it means to be rational affect our interpretation of the world around us? What problems arise as a result of our attempts to analyse rationality within the scope of naturalism? These essays offer fascinating discussion about the nature and extent of rationality - its content, focus, and the intrinsic guidelines for using the term "rational" when describing persons or actions.
