Five Ways Of Thomas Aquinas

Thomas Aquinas is a Saint and is a theologian who is proving the existence of God with his five different ways. Aquinas borrowed some of these arguments from Aristotle. The five ways are the proof from motion, the proof from causality, proof from possibility and necessity, proof from gradations, and the fifth way is the proof from governance.

The proof of motion must have been an unmoved first mover. Nothing can move itself; each thing in the world in motion is moved by something else. The sequence of motion cannot extend forever so there had to have been a first mover, put in motion by no one or nothing else. The world understands this to be God and all movement is initiated by God.

Similar to the proof of motion, the proof of causality

means there has to have been a first cause or a reason behind it explaining why. “There must be a first, uncaused cause to explain the existence of all other causes.” (Aquinas, 147) One had to start the cause movement of all existence. Nothing exists before itself which means nothing is the cause of itself. “Every effect must have a cause, if you eliminate the cause you eliminate the effect.” (Preacherwin) If a previous cause does not exist, neither does the thing that results the effect. If the “first thing” in a chain does not exist, nothing in the chain exists. If the chain of causes extends forever into the past, then no things would exist now, which is false. Causes do not extend forever into the past which is the proof to admit a first efficient causer is God.
Aquinas third way is the proof from possibility and necessity that argues without God there would be no order. It's possible for some things to exist and possible for them not to exist. God has to exist or the world and humans would all be blobs. There would be no system or order of any body parts. The proof of order is we humans are symmetrical and balanced. If there was one time nothing was in existence, it would have been impossible for anything to begin to exist; and even now nothing would exist. It would be foolish to think we humans designed ourselves.
