The Dream of Descartes by Francois Mauriac contains articles appearing in 1920 and 1922, a lecture, and other essays. This book was written to determine the value and significance of the Cartesian Reform with regard to metaphysical and theological wisdom. Descartes was also known for his work in producing the Cartesian Theory of Fallacies. This can be most easily explored using the statement: "This statement is a lie." While it is most commonly referred to as a paradox, the Cartesian Theory of Fallacies states that at any given time a statement can be both true and false simultaneously because of its contradictory nature. The statement is true in its fallacy. Thus, Descartes developed the Cartesian Theory of Fallacies, which greatly influenced the thinking of the time. Many would-be philosophers were trying to develop inexplicable statements of seeming fact, however, this laid rumors of such a proposition impossible. Many philosophers believe that when Descartes formulated his Theory of Fallacies, he intended to be lying, which in and of itself embodies the theory. Titles in this book are "The Deposition of Wisdom," "The Cartesian Proofs of God," and "The Cartesian Heritage." Mauriac, Fran ois 1885-1970, French writer.
