Clement of Rome

The great cannot subsist without the small, nor the small without the great. There is a kind of mixture in all things, and thence arises mutual advantage. Let us take our body for an example. The head is nothing without the feet, and the feet are nothing without the head; yea, the very smallest members of our body are necessary and useful to the whole body. But all work harmoniously together, and are under one common rule for the preservation of the whole body.
