Hi, I have taught logic at various levels for some years. Here are a couple of suggestions. I don't know of many (or any) good logic tutorials on the net. I don't like the wikipedia thingy very much, although I don't think there is any problem with the emphasis on nl argument -- it seems to me that it would be more likely for your New Fancy Theorem Prover to be used in some nl-processing related task rather than to test the independence of large cardinals conjectures. There are some very good entries in the Stanford Encyclopedia of Philosophy (http://plato.stanford.edu), beginning with the classical logic article by Stewart Shapiro. These are useful to get an idea of the variety of things covered, though likely not suited to initial study or self-study (as always, your mileage etc.). There are couple of really good books which I have liked much and I think would be good for a 'select' beginner: A Logic Primer, by C. Allen and M. Hand. MIT Press. (An added benefits is that it sells for $15 or so) Natural Logic, by N. Tennant. I fear this is out of print. Used to be published by the U. of Edinburgh Press. The "Primer" is as concise as can be, and Allen and Hand claim it to be 'for use with an instructor', but I think for someone wanting to learn the basic formal presentation of a natural deduction system, and to find a ton of exercises for practice, the information is there. Covers only classical FOL, via natural deduction Lemmon-style (in fact, it basically uses Lemmon's system and notation except for a couple of minor changes). There is also a well-designed web-site where one can practice with the proof system, http://logic.tamu.edu. Tennant's book actually covers a lot of stuff for its size, including classical semantics and basic (and not so basic) meta-logic, intuitionistic logic, Kripke semantics for same etc. It presents natural deduction Prawitz-style, which I find more interesting and more illuminating as to various other more advanced topics (like normal form theorems etc.). The book is more advanced than the "Primer," obviously. I have occasionally tried to convince Tennant to revise and reprint, but I'm not sure he has any plans. I don't know of a lot of intro books that use Hilbert-style, as opposed to natural deduction, presentations. A great book of course is Harold Enderton's (recently republished), used in many semi-advanced courses. I'm not sure how it would be to start with that, but maybe with a good math background it wouldn't be too bad. I haven't read Waldinger-Manna unfortunately (for me, I suppose), but what I have read about theorem provers and automated deduction is generally very strongly focused on engineering (as one would expect), not logical issues. I don't think one would get a good appreciation for the basic notions and their main consequences by reading that. (And the basic notions are both simpler and more general anyway.) I have bought a couple of Prolog books (authors will go unnamed) where the reader really has to do some work just to figure out that the comma is equivalent to logical conjunction or some such.
