In this collection of 18 essays written over a period of about 20 years, author Martin Aronson muses on a variety of topics, which span from the sublimely philosophical to the earthily pragmatic. Written with the intention of originally and coherently exploring a personal topic of interest, each essay attempts to wed insight with clarity. In Cogito, the author meditates on such concerns as the nature of chaos and wholeness, the direction of Western civilization, the dual conception of God, the trinity motif in the world's major religions, and the likely dominant trends in history during the next 50 years. Though each essay is a complete study in itself, the reader can trace the evolution of thought of an arresting and provocative contemporary thinker.
