Opinion (n.) cannot ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠be its own test — a madman also does what seems good to him; philosophy begins by distrusting it and looking for a standard like a scale or a carpenter's rule.

An Opinion (n.) not ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠yet firm is wax and should be kept out of the sun, or whatever you write in school will melt away day by day.

Opinion (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the only cause of anything we do — not death, not exile, not toil, but our judgements and the decisions of our will.

Opinion (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the madman's criterion too — he also does what seems good to him; so look for something higher than “it seems to me.”

Opinion (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠no measure of truth — why mine rather than the Syrians' or the Egyptians'? — so philosophy goes looking for a standard, as we once did for weights and lengths.
