@wayne,
Wayne,
I understand (or at least I try to understand) what "some events are necessary events" means. What I didn't know is if Ughaibu understands it.
The planes did not have to crash, yet the planes did have to crash. That would be contradictory if by “have” I meant the same thing in both instances.
The planes did not have to crash, for the fact that each plane took off is a contingent truth, not a necessary truth. Even after the planes crossed the point of no return, it’s still so that the planes did not have to crash, and I say that because I’ve already established that they did not have to crash by showing the fact that each plane took to the air is a contingent truth. (The logical must)
Yet, the planes did have to crash. Once the planes passed the point of no return, the crash was inevitable. No other real possibilities existed that would allow a mere close call. Guaranteed by the laws of our universe, events were set in motion that would lead to no outcome other than the planes crashing. (The physical must)
If on the one hand I’m saying that the planes did not have to crash yet on the other hand saying that the planes did have to crash, then how is what I’m saying not a contradiction? Because on the one hand I’m talking about the logical must and on the other hand I’m talking about the physical must. They are compatible!
Logically speaking, the fact that the planes crashed is not a necessary truth but rather a contingent truth, and because the fact is not a necessary truth, the planes did not have to crash. This fact (that it’s a contingent truth) does not detract from the reality of what did happen after the planes crossed the point of no return. Sad are we that simply describe the events as something that did happen (and not something that must happen) since what did happen was what happened AFTER the point of no return.
By the way, the peculiar view of determinism that I’ve mentioned a couple times would say that the planes did have to (the physical must) crash, but not only does it say that the planes had to crash after the point of no return, it also says that the planes had to crash (the physical must) even before the point of no return was reached. Way before.
