Nobody can have the consolations of religion or philosophy unless he has first experienced their desolations. – Aldous Huxley, Themes and Variations, 1950
Upon the whole, I am inclined to think that the far greater part, if not all, of those difficulties which have hitherto amused philosophers, and blocked up the way to knowledge, are entirely owing to our selves. That we have first raised a dust, and then complain, we cannot see. – George Berkeley
