恶言不出于口，邪行不及于己。
语出汉·桓宽《盐铁论·毁学》。坏话不说，坏事不干，可谓洁身自好。
Freedom is not merely the opportunity to do as one pleases; neither is it merely the opportunity to choose between set alternatives. Freedom is, first of all, the chance to formulate the available choices, to argue over them—and then, the opportunity to choose.
