A self-evident and necessary truth, or a proposition whose truth is so evident as first sight that no reasoning or demonstration can make it plainer; a proposition which it is necessary to take for granted; as, "The whole is greater than a part;" "A thing can not, at the same time, be and not be."
An established principle in some art or science, which, though not a necessary truth, is universally received; as, the axioms of political economy.
It has long been an axiom of mine that the little things are infinitely the most important. Arthur Conan Doyle
We're taught Lord Acton's axiom: all power corrupts, absolute power corrupts absolutely. I believed that when I started these books, but I don't believe it's always true any more. Power doesn't always corrupt. Power can cleanse. What I believe is always true about power is that power always reveals. Robert Caro
The idea that to make a man work you've got to hold gold in front of his eyes is a growth, not an axiom. We've done that for so long that we've forgotten there's any other way. F. Scott Fitzgerald
There are neither good nor bad subjects. From the point of view of pure Art, you could almost establish it as an axiom that the subject is irrelevant, style itself being an absolute manner of seeing things. Gustave Flaubert
It is an axiom, enforced by all the experience of the ages, that they who rule industrially will rule politically. Aneurin Bevan
