The Kalam Cosmological Argument

For the purposes of this debate, I take the sign of a poor argument to be that the negation of the premises are more plausible than their affirmations. With that in mind, kohai must demonstrate that the following premises are probably false:KCA1. Whatever begins to exist has a cause.2. The universe began to exist.3. Therefore, the universe has a cause.We come first to premise (1), which is confirmed in virtually ever area of our sense experience. Even quantum fluctuations, which many suppose to be uncaused, are causally conditioned in that they depend on the existence of a pre-existing quantum vacuum. Indeed, if we suppose (1) to be false, then there is nothing preventing just anything and everything from popping into existence anywhere and at any time. But obviously this doesn't happen -- the universe exhibits regular law-like behavior.In fact, we see that (1) is a logically necessary truth, the denial of which is self-contradictory. As David Oderberg argues:We are asked to countenance the possibility of the following situation: the nonexistence of anything followed by the existence of something. The words “followed by” are crucial — how are they to be interpreted? What they cannot mean is that there is at one time nothing and at a subsequent time something, because the nonexistence of anything is supposed toinclude time: to say that at one time there is nothing whatsoever is self-defeating because it is to say that there is a time at which nothing exists — hence something did exist. But it is hard to see how else we are supposed to understand “followed by”; or when the denier of the causal principle says that it is possible for something to come from nothing what are we to understand by “from”? Again it cannot have a causal sense because something is supposed to have come into existence uncaused. All that appears to be left is a timeless contradiction — the existence of nothing and the existence of something. [1]Moreover, even if it was shown that there could be such things as effects without causes (Nevermind that it would destroy the idea of causal regularity as we see it), this only barely scratches the KCA. We can simply recast the argument in inductive terms, arguing that it is probable that whatever begins to exist has a cause, and from that draw the conclusion that the universe probably has a cause. Even this less stringent formulation of the KCA is enough to satisfy the conditions of being a good argument.Dan Barker (Who my opponent is sure to cite), argues that P1 is question-begging because the only member of the class of objects which do not begin to exist is God. Hence P1 becomes "Everything except God needs a cause." However, this criticism is grossly off-point. First, the modified-P1 is simply not logically equivalent to P1. If we recast the KCA using M-P1, then the argument becomes structurally invalid. Second, M-P1 confuses meaning with reference. The two premises may refer to the same object, but their meaning is obviously different. Third, whereas M-P1 is framed in terms of being an existential statement (One which asserts the existence of something), P1 is a universally quantified statement. Consider the formalized version of the argument:1. (x) (Bx -> Cx)2. Bu3. CuWhere B = begins to exist; c = cause, u = universe.Universally quantified statements do not commit one to the existence of classes of objects, whereas existential statements (Such as Barker's M-P1) do. Hence P1 and M-P1 are not logically equivalent.Premise 2If premise (2) is false, then it follows that the universe never began to exist. But, if the universe never began to exist, then the number of past events must have been actually infinite in duration. This assumes that the existence of actually infinite sets in re is possible. But if in fact actually infinite sets cannot exist in reality, then (2) must be true.Several types of arguments can be advanced in favor of this thesis. I will mention two.Hilbert's HotelSuppose that we have a hotel with an actually infinite number of rooms and that an actually infinite number of guests arrives. The manager easily accomodates the guests, and that's that. But now suppose that another guest arrives. "No problem!" says the manger, and he moves the guest in room #1 into room #2, the guest in room #2, into room #3, and so on. In a flash, the fully occupied hotel suddenly has one more room. But how can this be? The hotel was already full!Now suppose that an actually infinite number of new guests arrives looking for rooms. Without breaking a sweat, the manager moves each guest into a room that is twice his own. As a result, all of the odd numbered rooms become vacant, and the guests are accomodated without issue. But again, how can this be? The hotel was already full prior to their arrival! But now suppose that all of the guests in the even numbered rooms check out. It would still be the case that the hotel had just as many guests as before. In fact, with some re-arranging, the manager could turn his half empty hotel into one that's jam-packed. But how can this be?Hilbert's hotel is rightly absurd, and it illustrates the absurdities that could result if actually infinite sets did exist in reality. Because mathematical operations involving actually infinite sets lead to contradictions, they cannot exist in reality.The Grim Reaper ParadoxThis can be seen as an argument in itself, and as an argument to support Hilbert's Hotel. If Hilbert's Hotel is possible, then the Grim Reaper Paradox is possible, but if the Grim Reaper Paradox is not possible, then Hilbert's Hotel must be impossible at well.Suppose that there are a countably infinite number of grim reapers (GR) who want to kill you between 10AM and 11AM, meaning that you will not survive past 11AM. Now suppose that each GR wants you kill you at a time 1/n from 10AM. So:GR-1 will strike at 11GR-2 will strike at 10:30GR-3 will strike at 10:15etc...We see that for every GR which could have killed you, there must have been one before it which would have killed you. But since there is an infinite number of grim reapers, it follows that you will not be killed. Yet it is true that you will not survive past 11AM. So we seem to have a contradiction here in the idea of a backwards infinite sequence of events. How is this relevant to P2? Alexander Pruss argues the following [2]:1. If there could be a backwards infinite sequence of events, Hilbert's Hotel would be possible.2. If Hilbert's Hotel were possible, the GR Paradox could happen.3. The GR Paradox cannot happen.4. Therefore, there cannot be a backwards infinite sequence of events.These two arguments support the truth of P2. There are also scientific arguments for P2, but I will not cover them in my opening argument.Premise 3It must be noted that since there is nothing prior to the cause of the universe, it cannot be explained scientifically, as this would imply the existence of antecedent determining conditions. Because there are no prior determining conditions, the cause of the universe must be personal and uncaused, for how else could a timeless cause give rise to a temporal effect? Moreover, the cause must transcend both matter and time to create matter and time. Finally, in order to create the universe ex nihilo, this cause must be enormously powerful, if not omnipotent. One is warranted in concluding that therefore, God exists.With that, I now turn it over to kohai for his opening argument.___________Sources1. David S.
