Let us suppose, I kill an ape. Nobody touches me. Suppose it is a particularly clever ape. Nobody touches me. Suppose it is a new ape – a hairless, speaking species. Nobody touches me. By ascending these subtle steps circumspectly, I may climb up to Liebnitz or Shakespeare and kill them, and nobody will touch me, as it is impossible to say where the border was crossed, beyond which the sophist gets into trouble. — Vladimir Nabokov, Despair
