Check out this list of Clarence Darrow quotes from Uriupina.
The fact that life is here, to my mind, proves nothing, excepting that if you got a certain amount of earth and heat and water— if they were resolved into the simple elements—given these elements in certain proportions under certain conditions, life will develop, just as maggots will in a cheese. Does that prove it is worth while? I cannot see it. It does not prove it in any meaning of the words worth while. If it does prove it, then everything is equally worth while, and the living man is no more a part of nature than the corpse. And the well man is no more a part of nature than the sick man. The pleasurable emotion is no more a part of nature than the painful emotion. The fact that it is here simply proves it is here, that is all.
