"I know truth is more like a mountain that has to be scaled. The peak of the mountain pierces the clouds and can only rarely be seen, and has never been reached. And what you see of it, moreover, depends upon the flank of the mountain you stand upon, and how exhausted getting even so far has made you. Virtue lies in looking upwards, toiling upwards, and sometimes joyously leaping from one precarious crag of fact and feeling to the next."
