Dear friends :),
The First Cause must be, for it must exist as a thing which requires no cause at all, because logic dictates it. Just the fact that you cannot imagine it does not mean you cannot conceive of it. Our first cause is not to be a bearded man.
If everything we observe is caused by something else, there must be something which is not caused; rather, there must be something that is not in the system of cause-and-effect, as the system of cause-and-effect is too unstable to be its own source. Since the physical and energetic Universe is made up of things which are in causal relationships and contingent upon one another, the Universe itself cannot be the infinite, “necessary” thing; all its components are finite and dependent upon one another. The conclusion is that a thing outside destructible and changeable space must have created space, for destruction and change cannot be stable or “necessary” in of themselves!
I’m saying there must be a realm outside this causal realm, because the causal realm’s very nature implies a cause. This realm outside causality cannot be affected BY causality, or else it would just be part of the causal realm, and thus caused. Does that make sense?
Rationalists and atheists like to say that they take themselves where logic leads them, but if they deny that God must exist they are being hypocritical. When reason and logic take you to the conclusion that there must be a First Cause outside causality, and you deny that because you simply don’t want God to exist, then you are NOT following reason and logic.
What is your opinion of this notion?
