The primary objective in writing Fundamentals of Western Philosophywas to identify the foundational ideas of Western Philosophy and present them in a language and format that would be easily understood by undergraduates and the reading public. Most of the ideas proposed and explained in this book form the content of general introductory textbooks of philosophy. However, the book introduces not only philosophers rarely treated in introductory courses but is also primarily based on the very works of the philosophers themselves. It aims indeed to relate, in as faithful a manner as possible, the main ideas of Western Philosophy and the arguments that sustain them as expounded by their main exponents and based on their most representative texts. Where possible. they are reported in a chronological order. Where it has not been feasible to do so, they have been divided first into their respective schools of thought before presenting them chronologically.
