Quote

It must be granted that in every syllogism, considered as an argument to prove the conclusion, there is a petitio principii. When we say, All men are mortal Socrates is a man therefore Socrates is mortal it is unanswerably urged by the adversaries of the syllogistic theory, that the proposition, Socrates is mortal.

John Stuart Mill
