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

Consciousness is never experienced in the plural, only in the singular. Not only has none of us ever experienced more than one consciousness, but there is also no trace of circumstantial evidence of this ever happening anywhere in the world. If I say that there cannot be more than one consciousness in the same mind, this seems a blunt tautology — we are quite unable to imagine the contrary...
erwin schrödingerThere can be no more thrilling idea of intimacy that connecting with someone through the agency of the written word. Here we meet, on the page, naked and unadorned: shorn of class, race, gender, sexual identity, age and nationality. The reader I seek is a tautology, for he/she is simply…the person who wants to read what I have written.

mark twain...a theorem of propositional logic if and only if f(p1, p2 ,..., pn) is a tautology . ... He (Emil L.Post) uses the word to discuss the adequacy of a system of functions to express all the possible truth tables (this is nowadays called truthfunctional completeness). In this way he shows not only that through the connectives of Principia (? and ?) one can generate all possible truth tables but also that there are only two connectives which can, singly generate all the truth tables.
Pure mathematics , being mere tautology, and pure physics , being mere fact, could not have engendered them; for creatures to live, must sense the useful and the good; and engines to run must have energy available as work:;: and both, to endure, must regulate themselves. So it is to Thermodynamics and to its brother ?p log p , called Information theory, that we look for the distinctions between work and energy and between signal and noise.
