Plantinga's "Two Dozen (or So) Theistic Arguments"

Through the links on the Wikipedia page about philosopher Alvin Plantinga, I found a piece by him entitled "Two Dozen (or So) Theistics Arguments." Available here in PDF. The article is labeled "Lecture Notes by Alvin Plantinga" and is accordingly in a rough form, with a lot of points merely suggested rather than explained. Much of it (especially the first half) is also pretty dense.

I thought it would be interesting to summarize (and inevitably oversimplify) Plantinga's list here:

1. Ontological (or Metaphysical) Arguments

A. Argument from Intentionality (or Aboutness) -- if propositions have intentionality, then some being before us must have thought them.

B. Argument from Collections -- sets exist independently of human minds and are so numerous that they require an infinite mind.

C. Argument from Natural Numbers -- similar to B but using numbers.

D. Argument from Counterfactuals -- counterfactual reasoning is based on an ability to sort meaningful from irrelevant similarities and differences; that ability is ineffable.

E. Argument from Physical Constants -- why is the universe isotropic, in the precise way that makes life possible?

F. The Naive Teleological Argument -- why does the natural world appear to be orderly?

G. Tony Kenny's Style of Teleological Argument (Plantinga simply lists this one without any comment)

H. The Ontological Argument (ditto)

I. Another Argument Thrown in for Good Measure -- contingent beings (such as humans) could not exist without some necessary being.

2. Epistemological Arguments

J. Argument from Positive Epistemic Status -- why do so many natural things work properly?

K. Argument from the Confluence of Proper Function and Reliability -- why do our beliefs correspond reliably with reality?

L. Argument from Simplicity -- theism is the simplest explanation.

M. Argument from Induction -- what's the origin of our belief that things in the future will happen as they typically have in the past?

N. The Putnamian Argument (Argument from the Rejection of Global Skepticism) -- A Christian-type god would not deceive us "in a disgustingly wholesale manner"; therefore, the brain-in-a-vat hypothesis can't be true; therefore, since we "know" that the brain-in-a-vat hypothesis is not true, there is a god.

O. Argument from Reference -- Similar to N, but turning on the proposition that we would not be able to think the thoughts we have if there were not an outer reality that they correspond to.

P. The Kripke-Wittgenstein Argument from Plus and Quus (Plantinga simply lists this one without any comment)

Q. General Argument from Intuition -- where do our true intuitions come from?

3. Moral Arguments

R. Moral Arguments -- where do objective moral facts come from?

R*. Argument from Evil -- certain kinds of human evil is so utterly appalling that it requires divine judgment.

4. Other Arguments

S. Argument from Colors and Flavors -- why is there a correlation between physical and psychical properties?

T. Argument from Love -- where does love come from?

U. Mozart Argument -- where does appreciation of beauty come from?

V. Argument from Play and Enjoyment -- why is our pleasure connected with certain things?

W. Arguments from Providence and from Miracles (Plantinga simply lists this one without any comment)

X. C.S. Lewis's Argument from Nostalgia -- why do certain things make us think of a creator?

Y. Argument from the Meaning of Life (Plantinga doesn't really explain this one)

Z. Argument from A to Y -- why are there so many questions that are readily answered by positing a god?
