Hi everyone, I would like to reply to various people's comments since my post so far. I'll try to be as clear as I can, though words aren't well cut out for metaphysics, as you probably are aware.

I think we all want to know what principles and axioms we must accept as primitives to construct a theory of everything. However, I want to see how far we can get assuming no primitives. By primitives, I mean truths (or as Nietzsche liked to call them, "assumptions") that can't be proved with certainty, but can be used to derive and justify many other truths. An example of a primitive is "I am not a brain in a vat"; I can't prove it beyond an unreasonable doubt, but nonetheless I take it for granted in my normal day-to-day theorizing about the world. Bruno says he takes as primitives in his TOE axioms such as comprehensibility and reflection, and 0 and succesor. Unlike a primitive truth, a tautology is a vacuous, empty truth. The proposition "apples are apples" conveys no meaning. X = X is just the Law of Identity. I believe contra Bruno that all mathematical/logical/physical truths are tautological. Somehow or other, they must all be reducible to 0 = 0. Bertrand Russell said, "Everything that is a proposition of logic has got to be in some sense or the other like a tautology." Unfortunately, I cannot back up this awfully ambitious thesis since I'm not a mathematician, I'm just a philosophy major at the University of Michigan. Many mathematicians (perhaps Gödel) might have already disproven it or (worse) shown it to be unfalsifiable. Nonetheless, I trust Russell and Pearce on this one. Pearce says in his article (http://www.hedweb.com/nihilism/ nihilfil.htm): "The whole of mathematics can, in principle, be derived from the properties of the empty set, Ø. [Since Ø has no members, in the standard set-theoretic definition of natural numbers it can be identified with the number zero, 0. (this is still problematic; should 0 be regarded, not as the empty set, but as the number of items in the empty set? And what's the ontological status of the empty set?)] The number 1 can be defined as the set containing 0, i.e. simply the set {0} that contains only one member. Since 0 is defined to be the empty set, this means that the number 1 is the set that contains the empty set as a member {Ø}. The number 2 can be understood as the set, {0, 1}, which is just the set {Ø, {Ø}}. Carrying on, the number 3 is defined to be the set {0, 1, 2} which reduces to {Ø, {Ø}, {Ø, {Ø}}} Generalising, the number N can be defined as the set containing 0 and all the numbers smaller than N. Thus N = {0, 1, 2 ...N-1} is a set with N members. Assuming only the concept of the empty set Ø, each of the numbers in this set N can be replaced by its definition in terms of nested sets. Proceeding to derive the rest of maths from the properties of the natural numbers is more ambitious; but it's conceivable in principle. All that then remains to be done is to explain the empty set i.e. why (a condition analogous to our concept of) the empty set must be the case]" Pearce later concludes that "if, in all, there is 0, i.e no (net) properties whatsoever, then there just isn't anything substantive which needs explaining." Jason and Roger, are you satisfied by this explanation of why there doesn't need to be a meta-explanation of why anything exists? Bruno you might object and say that Pearce takes as a primitive "the standard set-theoretic definition of natural numbers", in which zero is identical with the empty set and sets can be nested inside others to define other numbers (successor). But if zero and the empty set are identical, then their equality doesn't require further proof, it just is the Law of Identity. Also, I think Pearce's idea that reality is constituted (somehow) by empty sets nested in other empty sets supports the following idea of Roger's: "the existent state that is what has been previously called "absolute non-existence" has the unique property of being able to reproduce itself." Perhaps you guys are saying the same thing just in different words. I think the Law of Identity (0 = 0) is the fundamental law of reality, though it's a rather circular and vacuous law. Jason you say, "A meta- reality with no laws permits the existence of any structure that can exist." I think you imply here that only *some* things can exist. I think you would agree with me, then, that the Law of Identity determines what can and cannot be the case. For example, I cannot have one hand and two hands at the same time and place (though I might have two hands in one Hubble volume and one hand in another, unfortunately). Stephen, you say "Existence exists". Heidegger said "Nothing noths." (I just thought that might titillate you) Any comments and critiques are welcome!
