“ethics is not about platitudes, let alone tautologies, logic or mathematics, but about difficult choices - dilemmas.”
“Sometimes what appears to be a difficult ethical quandary is simply the product of ignorance about your options.”
“At a certain point talk about 'essence' and 'oneness' and the universal becomes more tautological than inquisitive.”
“Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning.”
“Nothing can be accomplished by logic and ethics.”
“Pure mathematics is in its way the poetry of logical ideas.”
