But what caused the "something else" then? You're in a viscous infinite regression. The is no something that caused the something that caused the something ... ad infinitum.
Right! Now you're onto it.
In any causal chain, event X cannot occur until some other event (X-1) has already taken place. If X-1 hasn't occurred, then it's not the cause of event X: that's very clear.
Let me break it down small -- not for
you, since I can see you already get it -- but for anyone reading along with the strand, so that we take them with us.
So let's say, for example, your father caused you to exist. If he did not pre-exist your birth (say, if he won't be born until 2019), then he's not your father, and not the cause of your existence. But your father was caused by your grandfather: and he had to be born before your father, who had to be born before you...and so on.
Likewise, your birth (let's call that "event X") was caused by your father (X-1), who was caused by your grandfather (X-2), who was caused by your great grandfather (X-3)...and so on. That's all obvious, right?
Your birth is one of many "caused," material events. Every chain of such events
needs a starting point. If it did not have one, it could not start at all, since the pre-requisite (causal) event for its existence would not ever have taken place, because it would be lost in an infinite chain of other necessary prerequisite events.
But we observe causal chains every day. Heck, we ARE products of a causal chain.
So how does that come about? That's the issue. We know for certain
that it came about; but we are challenged to say
how.
If the past were infinite, then nothing would exist...because there would be no "starting point" from which the causal chain of events we observe every day could have ever commenced.
What follows is simply this:
the past is not infinite. It must have had an uncaused starting point, and whatever that starting point was, it must have been something outside of the causal chain of material events. That may sound strange to think about, because we're accustomed to limiting our thinking to belief in material events. But material events, and the causal chain that produces them, cannot be infinite...and that we know absolutely, by deduction, not merely inductively or by guess.
Conclusion: the ultimate cause of the causal chain and of the material events we witness every day is necessarily a single entity that is itself not a product of a causal chain of material events. For if it were, then it also would never have commenced, and we would have infinite regress again.
To go back to the OP, we should observe that that's also one of WLC's points. But now we're both on the same page about that, I think.
