This argument assumes that there is an uncaused-cause that necessarily exists and that anything else existing other than that which is necessarily real is not intrinsic to the nature of the uncaused cause and is ontologically unnecessary. We have established that physical reality is unnecessary.
1. Unnecessary things exist; this is to say that their existence is not necessary.
2. It is evident that unnecessary beings move to particular ends, and they do so because of their given nature.
3. Because their given nature is not ontologically necessary it cannot be said that any particular nature they have should necessarily have a particular effect, and the only case in which a thing must do a particular thing is because doing otherwise would conflict with the law of non-contradiction. A ball being thrown at glass doesn’t necessarily mean it has to smash. It could be that a hole will open up in the glass and the ball will move through it, after which the hole will close. It’s possible because the existence of any nature is not necessary other than the uncaused cause and neither is their effects other than what is logically necessary.
4. Yet we find unnecessary things doing what they do not necessarily need to do in a consistent fashion…This is what we characterize as the laws of physical behavior.
5. Since the uncause cause cannot be said to be governed by the laws of physics, it cannot be said that the laws of physics as we find them is a necessary feature of reality
6. Therefore when the uncaused cause creates unnecessary things it is also causing them to act to particular ends that are not necessary,.
7. Causing things to act in a particular way that is not necessary requires intention and therefore knowledge since things do not act in any particular way for no reason. We have some analogous understanding of this from our own intellectual activity like when we create bricks to build a house. But in the case of the uncaused cuase it is creating the very nature and the end to which the uncaused cause intends it to act.
Conclusion: Therefore the uncaused cause is an intelligent cause
