I've read several works by Oscar Wilde and was aware as I read that many of his sentences would work as aphorisms, and I see that Wikipedia agrees with me. To their list I would add George Orwell (Eric Arthur Blair) and Mark Twain (Samuel Clemens). And Audre Lorde had some pretty darned pity lines in her poetry. Florynce Kennedy (gotta have a couple of angry Black women in the list.)
