The way in which men cling to old institutions after the life has departed out of them, and out of themselves, reminds me of those monkeys which cling by their tails - aye, whose tails contract about the limbs, even the dead limbs, of the forest, and they hang suspended beyond the hunter's reach long after they are dead. It is of no use to argue with such men. They have not an apprehensive intellect, but merely, as it were a prehensile tail.
Henry David ThoreauAs for conforming outwardly, and living your own life inwardly, I do not think much of that. Let not your right hand know what your left hand does in that line of business. It will prove a failure.... It is a greater strain than any soul can long endure. When you get God to pulling one way, and the devil the other, each having his feet well braced,--to say nothing of the conscience sawing transversely,--almost any timber will give way.
Henry David Thoreau
