Some may remember, if you have good memories, that there used to be a concept in Anglo-American law called a presumption of innocence, innocent until proven guilty in a court of law. Now that's so deep in history that there's no point even bringing it up, but it did once exist. Noam Chomsky
We are not actually in charge of life, yet behave as if we are the masters of our own destiny. The realization of this fact is quite a hard one. The ridiculousness of our pomposity and presumption can only result in anger or humor. Billy Childish
