Speaking of Tautologies
Jay McCarthy quotes Murray Rothbard:
A guy said to me, ‘yes, but the whole theory of evolution is based on a tautology: that which survives, survives’ This is tautological, therefore it doesn’t mean anything. I thought about that for a while and it finally occurred to me that a tautology is something that if it means nothing, not only that no information has gone into it but that no consequence has come out of it. So, we may have accidentally stumbled upon the ultimate answer; it’s the only thing, the only force, arguably the most powerful of which we are aware, which requires no other input, no other support from any other place, is self evident, hence tautological, but nevertheless astonishingly powerful in its effects.
Things either exist or they don’t.
That which exists is true, that which does not exist is false.
