“The assimilation of tautologies and contradictions with true and false propositions respectively results from the fact that tautologies and contradictions can be taken as truth-functions just like ordinary propositions, and for determining the truth of falsity of the truth-function, tautologies and contradictions among its arguments must be counted as true or false respectively. …Are the propositions of symbolic logic and mathematics tautologies in Mr Wittgenstein's sense?”

“A tautology's truth is certain, a proposition's possible, a contradiction's impossible.”

Ludwig Wittgenstein book Tractatus Logico-Philosophicus

Certain, possible, impossible: here we have the first indication of the scale that we need in the theory of probability.

“Tautologies and contradictions are not real propositions, but degenerate cases. …Clearly, by negating a contradiction we get a tautology, and by negating a tautology a contradiction. …A genuine proposition asserts something about reality, and it is true if reality is as it is asserted to be. But a tautology is a symbol constructed so as to say nothing whatever about reality, but to express total ignorance by agreeing with every possibility.”

“Like all of mathematics, game theory is a tautology whose conclusions are true because they are contained in the premises.”

“Egoism in its narrowest sense is a tautology, not a tactic.”

Bob Black (1951) American anarchist

Preface to The Right To Be Greedy (1983 edition)
Context: Egoism in its narrowest sense is a tautology, not a tactic. Adolescents of all ages who triumphantly trumpet that "everyone is selfish," as if they’d made a factual discovery about the world, only show that they literally don’t know what they’re talking about. Practical egoism must be something more, it must tell the egoist something useful about himself and other selves which will make a difference in his life (and, as it happens, theirs). My want, needs, desires, whims — call them what you will — extend the ego, which is my-self purposively acting, out where the other selves await me. If I deal with them, as the economists say, "at arm’s length," I can’t get as close as I need to for so much of what I want. At any rate, no "spook," no ideology is going to get in my way. Do you have ideas, or do ideas have you?

“If he will not be satisfied with truth in the form of tautology, that is to say, if he will not be content with empty husks, then he will always exchange truths for illusions.”

Friedrich Nietzsche (1844–1900) German philosopher, poet, composer, cultural critic, and classical philologist

On Truth and Lie in an Extra-Moral Sense (1873)
Context: Are designations congruent with things? Is language the adequate expression of all realities?
It is only by means of forgetfulness that man can ever reach the point of fancying himself to possess a "truth" of the grade just indicated. If he will not be satisfied with truth in the form of tautology, that is to say, if he will not be content with empty husks, then he will always exchange truths for illusions.
