Here is a little extract to whet your appetite:
How do we know a living being whom we cannot see? By the movement of which he is the cause. The, mole under the ground, the hare in the bush, the heart beneath the fingers. For we see that the whole universe is in movement. In this world all is movement, all bears witness to the divine restlessness of nature, always in a state of creation, incapable of existing by itself or in the presence of an unmoving Creator; everything betrays perpetual change.
