This volume explores the most important questions and issues that have absorbed philosophers over the past twenty-five centuries. The quest to define reality, the problem of the existence of God, the search for moral values, the problem of evil, the discovery of the self, and other philosophical issues are clearly outlined in six thematic chapters. The ideas of ancient, medieval, and modern philosophers are integrated into a reflective and compelling narrative, which aims at emphasizing the timeless relevance of these questions and concerns and at eliciting from the readers their own responses to the issues raised. The book includes a comprehensive bibliography and two extensive glossaries that outline the theories of all the philosophers mentioned and explain the main philosophical terms used in the text. Designed specifically for undergraduate students taking their first courses in philosophy and for anybody who wishes to gain acquaintance with the subject, this comprehensive volume sheds light on the significance of the philosophical adventure.
