TItis book is the joint project of a philosopher, Lehrer, and a mathematician, Wagner. The book is, therefore, divided into a first part written by Lehrer, which is primarily philosophical, and a second part written by Wagner that is primarily formal. The authors were, however, influenced by each other throughout. Our book articulates a theory of rational consensus in science and society. The theory is applied to politics, ethics, science, and language. We begin our exposition with an elementary mathematical model of consensus developed by Lehrer in a series of articles 1976a, 1976b, 1977,...

Art can provide us with a sensory experience that provokes us to reconfigure how we think about our world and ourselves. Theories of art have often sought to find some feature of art that isolates it from the rest of experience. Keith Lehrer argues, in opposition, that art is connected, not isolated, from how we think and feel, represent and react. When art directs our attention to sensory exemplars in aesthetic experience of which we become conscious in a special way, it also shows us our autonomy as we represent ourselves and our world, ourselves in our world, and our world in ourselves....

In this important new text, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the accepted definition of knowledge as justified true belief, Lehrer explores the truth, belief and justification conditions on the way to a thorough examination of foundation theories of knowledge, externalism and naturalized epistemologies, internalism and modern coherence theories as well as recent reliabilist and causal theories. Lehrer gives all views careful examination and concludes that external factors must be matched by appropriate internal ones...
