In Archetypes of Thought, originally published in 1991 with the title Philosophical Grounds, Thomas Molnar follows seven basic themes of Western philosophical speculation from their development in the earliest times of systematic thought through their evolution through the centuries and civilizations to the present. Some of the themes are origin and its reflection, guilt of being, one and the multiple, the temptation of mechanization, and nocturnal man. The book is neither a chronological treatment of issues nor a list of philosophical schools and movements. Rather, it reaches for the archetypes of philosophical reasoning. Molnar shows the presence of modern themes in the entire history of thinking, traces technology to the first stirrings of rationalism, and evinces modern man’s feeling of culpability. Throughout, the soul is perceived as the keeper of God’s and man’s secret, one which reflects reality and also tries to organize it according to an ontologically implanted rhythm. In his new introduction, Molnar explains and re-examines his reasons for writing the book. While the themes he covers have been widely dealt with in contemporary thought, they are brought together to form an original combination of philosophical concepts. Archetypes of Thought is an intriguing study of the evolution of philosophical thinking. It is essential reading for both students and professionals of philosophy, history, and sociology.
