Return to Truth
The existence of human volition cannot be used to justify the theory that there is a dichotomy of propositions or of truths. Propositions about metaphysical facts, and propositions about man-made facts, do not have different characteristics qua propositions. They differ merely in their subject matter, but then so do the propositions of astronomy and of immunology. Truths about metaphysical and about man-made facts are learned and validated by the same process: by observation; and, qua truths, both are equally necessary. Some facts are not necessary, but all truths are.
Truth is the identification of a fact of reality. Whether the fact in question is metaphysical or man-made, the fact determines the truth: if the fact exists, there is no alternative in regard to what is true. For instance, the fact that the U.S. has 50 states was not metaphysically necessary—but as long as this is men's choice, the proposition that "The U.S. has 50 states" is necessarily true. A true proposition must describe the facts as they are. In this sense, a "necessary truth" is a redundancy, and a "contingent truth" a self-contradiction.
