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
There's an axiom I live by: 'There is no art without politics.' You either choose to engage it, or you choose political apathy. This ties in with ideas around real-time performance and feedback. Chris Jordan
