When a human acts, he necessarily does so in order to achieve some end. In this way, he is moved by the intended end or the object sought. The end is actually the thing that moves or directs one's will to act.
Humans can reason better than cows for instance.
The perfection of the intellect and will are found in God, who as the uncaused cause, causes all things. For an intellect or will to exist in a lesser being, it must be perfected in the highest being, and God is Being itself. God is described as the prime mover, the uncaused cause. Furthermore, there is no distinction made between the divine intellect and the divine essence, since God is described as pure act and is a simple being in that He is not composed of other things.
