Truth

  • For the New Intellectual
    Truth is the recognition of reality; reason, man’s only means of knowledge, is his only standard of truth.
  • Introduction to Objectivist Epistemology
    Truth is the product of the recognition (i.e., identification) of the facts of reality. Man identifies and integrates the facts of reality by means of concepts. He retains concepts in his mind by means of definitions. He organizes concepts into propositions — and the truth or falsehood of his propositions rests, not only on their relation to the facts he asserts, but also on the truth or falsehood of the definitions of the concepts he uses to assert them, which rests on the truth or falsehood of his designations of essential characteristics.

    The truth or falsehood of all of man’s conclusions, inferences, thought and knowledge rests on the truth or falsehood of his definitions.
  • Introduction to Objectivist Epistemology

    Every truth about a given existent(s) reduces, in basic pattern, to: “X is: one or more of the things which it is.” The predicate in such a case states some characteristic(s) of the subject; but since it is a characteristic of the subject, the concept(s) designating the subject in fact includes the predicate from the outset. If one wishes to use the term “tautology” in this context, then all truths are “tautological.” (And, by the same reasoning, all falsehoods are self-contradictions.)

    When making a statement about an existent, one has, ultimately, only two alternatives: “X (which means X, the existent, including all its characteristics) is what it is”—or: “X is not what it is.” The choice between truth and falsehood is the choice between “tautology” (in the sense explained) and self-contradiction.

    In the realm of propositions, there is only one basic epistemological distinction: truth vs. falsehood, and only one fundamental issue: By what method is truth discovered and validated? To plant a dichotomy at the base of human knowledge — to claim that there are opposite methods of validation and opposite types of truth [as do the advocates of the “analytic-synthetic” dichotomy] is a procedure without grounds or justification.

  • Introduction to Objectivist Epistemology

    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.

  • Philosophy: Who Needs It
    [Consider the catch phrase:] “It may be true for you, but it’s not true for me.” What is the meaning of the concept “truth”? Truth is the recognition of reality. (This is known as the correspondence theory of truth.) The same thing cannot be true and untrue at the same time and in the same respect. That catch phrase, therefore, means: a. that the Law of Identity is invalid; b. that there is no objectively perceivable reality, only some indeterminate flux which is nothing in particular, i.e., that there is no reality (in which case, there can be no such thing as truth); or c. that the two debaters perceive two different universes (in which case, no debate is possible). (The purpose of the catch phrase is the destruction of objectivity.)
