This is a completely meaningless sentence. You can only do one thing! The notion of "doing it over again" is meaningless. It does not correspond to anything in reality.

Moral strictures and legal punishments appear to have a negative correlation against certain kinds of behaviors.

The medieval conceptions of the Yahweh are the troublesome ones. All this rot about all-knowing, all-powerful. If you postulate powerful, wise beings, worthy of worship, you don't run into such problems, although you may find it difficult to prove their existence. > This has > to be said very carefully.

So I suppose you are asking whether there is a world in which > every stement false IN THAT WORLD is true IN THAT SAME WORLD. Not really. The idea was that there are two classes of facts, ones that are true in this world but might be false in another (John's marriage), and others that must be false everywhere (2 + 2 = 5). But since other worlds do not exist, this isn't an issue. > identical, they are in fact the same thing.> Not really Physics, where it is > said in fact to be demonstrable that nothing is ever identical.

If two particles have the same exact sets of observable properties (spin, momentum, etc) they are interchangable and subject to a certain approach (B-E statistics, if I recall.)

It is entirely possible that ANY deviation from our known laws of physics involves a logical contradiction.

I fail to see how speculation on the properties and differences between worlds that DO NOT exist can help us understand anything in this one. They do not, and in a real sense could not exist! If we want to tie our logic to observed reality and derive useable results, we are obliged to ignore such fiction. > fixed and inexorable, does not mean that anybody has enough information to be > able to compute the future precisely.> Point?
