Aristotle believed that the only Truth (by Truth, we’re talking about something pure, immutable, absolute) that existed was God, the Unmoved Mover, the external force that initiated existence. He also believed that everything in the universe is moving through an innate process toward actualizing toward its fullest potential. All creatures, all objects, all people just move toward their greatest possibilities. They don’t have to think about it, they just do it. Life makes it happen.
Perhaps, and I think this is what Aristotle meant by the idea, the Unmoved Mover is also in the process of actualizing Its greatest potential. In fact, Its potential—the greatest potential that It always and forever more strives to attain, is Change. That’s all, simply Change itself.
In continuously striving to be something else, It is always in the process of recreating Itself, and it always succeeds. Meanwhile it is also concurrently fulfilling greatest potential. In this way, God and the Universe are perfect. God is always in the being of becoming. The Universe is always in the state of Change.
That’s the purpose. That’s the point. That’s what it’s all about.
Meanwhile, this Aristotelian God is floating out there somewhere in the ether, behind the Great Veil, completely absorbed in self-contemplation, detached from all events on Earth, accepting all that is and all that ever will be.
