Julius McCarter has written this book for people who want to think about the big themes -- knowledge, reason, truth, mind, freedom, destiny, identity, God, goodness, justice -- but, more importantly, to think about them philosophically. His method is to introduce what other philosophers -- primarily Plato, Descartes, Locke, Berkeley, Leibniz, Hume, and Kant -- have had to say about these themes. To make the arguments more understandable to the lay reader and student, he presents the problem in everyday language. To read this book is to sit down with an engaging, highly learned conversationalist; readers new to the subject could very well be captivated.
