Inspired from from a comment on Ezra Klein: A Bit More On Gore, I went looking for Sartre, first as a tool in service of blame, until about three paragraphs in, when it became a tool in service of knowledge. This caught my eye:
Tomorrow, after my death, some men may decide to establish Fascism, and the others may be so cowardly or so slack as to let them do so. Jean-Paul Sartre, Existentialism is a Humanism
So what will be your answer?
