80 pages, you’ve got to be kidding! How about reducing it to a syllogism?
Collins presents this syllogism on page 207 (the sixth page):
(1) Given the fine-tuning evidence, LPU is very, very epistemically unlikely under NSU: that is, P(LPU|NSU & k′) << 1, where k′ represents some appropriately chosen background information, and << represents much, much less than (thus making P(LPU|NSU & k′) close to zero).
(2) Given the fine-tuning evidence, LPU is not unlikely under T: that is, ~P(LPU|T & k′) << 1.
(3) T was advocated prior to the fine-tuning evidence (and has independent motivation).
(4) Therefore, by the restricted version of the Likelihood Principle, LPU strongly supports T over NSU.
All of the acronyms and terminology are explained on pages 202-206. I don’t know if that’s sufficiently reduced for your purposes, though. I happen to own a copy of the (much less rigorous) book The Rationality of Theism, which is a collection of short essays by the top defenders of various theistic arguments. We can discuss Collins’ presentation of the fine tuning argument in that book instead, if you’d like.
I’ve heard the fine tuning argument from William Lane Craig in debates, there are lots of them on YouTube, Christopher Hitchens and Lawrence Krauss have been his opponents, among others. So I’m fairly familiar with it.
Cool.
I say, “fine tuning”, compared to what? Are there other universes Dr. Craig has checked, and compared to ours? Ones where the metaphorical knobs and switches have been set differently? Of course not. Further, he doesn’t show us a mechanism by which such values are set, or can be changed. He points to factors like the force of gravity, which is governed by Newton’s inverse square equation, strong and weak nuclear force, the speed of light etc. and claims they are arbitrary values, and then slips in the premise of Primacy of Consciousness by claiming, therefore, that these values must have been “set” by someone (God).
I think this is Hume’s objection to the cosmological argument, correct? Swinburne refutes it as follows in The Existence of God (p. 134):
"From time to time various writers have told us that we cannot reach any conclusions about the origin or development of the universe, since it is the only one of which we have knowledge, and rational inquiry can reach conclusions obly about objects that belong to kinds, for example, it can reach a conclusion about what will happen to this bit of iron only because there are other bits of iron, the behaviour of which can be studied. This objection has the surprising, and to most of these writers unwelcome, consequence, that physical cosmology could not reach justified conclusions about such matters as the size, age, rate of expansion, and density of the universe as a whole (because it is the only one of which we have knowledge); and also that physical anthropology could not reach conclusions about the origin and development of the human race (because, as far as our knowledge goes, it is the only one of its kind). The implausibility of these consequences leads us to doubt the original objection, which is indeed totally misguided.
“Uniqueness is relative to description. Every physical object is unique under some description, if you allow descriptions that locate an object by its spatial position - that is, by its distance and direction from named objects. Thus my desk is the one and only desk in such and such an apartment; and that apartment is the penultimate one on the left in a certain row… My desk has in common with various other objects that it is a desk; and with various different objects, that is weighs less than a ton, and so on. The same applies to the universe itself. It is, for example, like objects within it such as the solar system, a system of material bodies distributed in empty space. It is a physical object and, like other physical objects, has density and mass. The objection fails to make any crucial distinction between the universe and other objects; and so it fails in its attempt to prevent at the outset a rational inquiry into the issue of whether the universe has some origin outside itself.”
The analytic theists (Swinburne, Plantinga, et al.) have refuted a lot of the Enlightenment objections to the arguments for God. News of this has, generally speaking, not reached the internet atheist community as yet.
