Plato, Crito 47a

“We should not esteem all the beliefs of humans, but rather esteem certain ones and not others, and even then, not the beliefs of all people, but rather the beliefs of certain people and not of others. What do you say? Is this not well said?”

οὐ πάσας χρὴ τὰς δόξας τῶν ἀνθρώπων τιμᾶν ἀλλὰ τὰς μέν, τὰς δ’ οὔ, οὐδὲ πάντων ἀλλὰ τῶν μέν, τῶν δ’ οὔ; τί φῄς; ταῦτα οὐχὶ καλῶς λέγεται;
