    I will study the topics you've recommended. Might take a year or two to work through Popper, but he's already on the list anyway. :)

    I have to warn you, though; I don't have much truck with non-empirical arguments or representational systems that are totally divorced from subjective reality. "I seen a cow, I seen a horse, but I ain't seen none of that thar bovinity nor horsiness neither" was Edward Abby's reply to Plato, and I have a similar reaction to Wittgenstein and his ilk. My mind doesn't work that way, I guess.

    Unfortunately your choice of examples shows that you are not arguing what you claim, innocently or not, to be arguing. Instead of arguing about proof, you're arguing about a corner of epistemology (the philosophical study of how we know things) known as empiricism.

    Yes; this has become apparent in retrospect; thanks for your help. The other posters were talking about the syntactical rules of a representational grammar (that is, today's version of math) whereas I'm talking about physical reality.

    Have you read Spinoza's Ethics? I'm working on it at the moment, because I'm trying to understand why so many pantheists (which he was and I am) have come to the conclusion that God has no personality. Spinoza states both the ideas he believes and those he disbelieves in the form of a "geometrickal proof" - not because he thought that mathematical proof was canonical proof, but because he wanted to restrict the incidence of misinterpretation of what he was saying by forcing the arguments into a very rigid, well known format. This apparently worked for a century or so but makes the work more difficult to comprehend for most modern readers. It also freaks out mathematicians because he essentially provides "geometrickal proof" of concepts he then states are false. Lots of interesting discussion of this here.

    One can indeed offer proof of the non-existence of a thing. What one cannot do is offer evidence of its non-existence. Evidence and proof are not the same. "Proof" is a logical idea and "evidence" is an empirical idea.

    If you want to prove something to me, you must provide independently verifiable evidence or describe a means of finding same. This, to me, is the meaning of the english word proof. It's also the number one definition on dictionary.com, incidentally, and you are only the second poster to state that you are using the special mathematical meaning for the words "proof" and "prove" and not the common english meaning. Again, my thanks to both of you.

    Standard logic is one system, amongst many, for extending knowledge. We seem to have a large measure of faith in logic because one of its consequences is that no group of true statements will ever lead to a contradiction. In other words it is a system born of our cultural uneasiness with contradictions.

    I'm not sure it's true that "no group of true statements will ever lead to a contradiction". I know that's the target, but I need to think on that a little more. Are you saying that all paradoxes are the result of erroneous axioms, or that our logic is imperfect because the syntactica of human communication permit paradoxical statements, or some combination of both?

    In fact, one way to logically extend our knowledge is to posit (assert) the truth or falsehood of a statement and then show (prove) that the rules of the logical system lead to a contradiction. Since your assumptions lead to a contradiction, logic says that at least one of your assumptions must be false. This is called "proof by contradiction" or, in classical terminology, "reductio ad absurdum."

    I understand. But without empiricism, the only thing that method is useful for is creating very abstract methods, and

    The patterns used by worms and spammers are extremely noticeable. You can identify them with Snort (free software) and you can slow them down with a tarpit (free software). It's almost impossible not to see the worms, in particular, if you are doing the most basic sorts of network monitoring in order to allow proper network management.

    It'd be easy to block infected machines, and machines that are spamming, using the DOCSIS cable modem (which is controlled by the ISP, not the end user). Reroute all traffic to and from infected machines to a special "hey you are infected here are some antidotes" network and charge the antivirus companies for the privilege of hawking their products and services on that network.

    Easy, that is, for a highly competent and experienced network engineer. Which is to say someone who commands a higher salary than the greedy broadband ISPs are apparently willing to pay.

    With Comcast's resources at my disposal, I could stop all spam and virus propagation from their networks in a month or less. But a certain number of customers (mostly spammers and other criminals) would stop paying their monthly bill as a result, and thus Comcast has a simple ROI equation: Screw you over, and get paid, do the Right Thing, and don't get paid.

    It does not sound as though you are open to other viewpoints. All your statements are presented as revealed truth, not as logically reasoned arguments.

    I personally believe science consists of skepticism and experimentation. I am highly skeptical of the ability of any human to discern that any theory is "the most successful" and I do not see any experiment that can be performed to support any such statements.

    Incidentally, "Might makes Right" is a perfectly defensible model of reality - not that I necessarily agree with that definition of "theory", but I'm willing to play along - based on three assumptions.

          Axiom1: If God exists, God is the biggest, most powerful thing there is.
          Axiom2: A thing may be composed of other things.
          Axiom3: God prefers Right to Wrong (tautology restatable as Right=what_God_prefers)

    I recommend to you the work of Baruch Spinoza, specifically the Ethics, and to Einstein's comments regarding Spinoza's idea of God, if you want to think deeply about the first two axioms; the last is an assumption based on faith (but all reasoning is based on faith, see Renee DesCartes Meditations on First Philosophy or the movie The Matrix if you don't agree).

    Finally, you've made much of "intuition", which is is not only entirely subjective, it's practically the opposite of science. I think that all things that are real would be intuitive to a sufficiently enlightened being; we humans are however limited to the capabilities of the meat engines that house us, and perhaps any being capable of intuition is similarly limited (though I doubt it).

                        Postulate that this has been done, and call the place the Dog Pound.
                        None of the dogs will have green, purple, or orange spots, because dogs don't come in those colors, therefore they cannot have spots of those colors.

          Therefore, we just proved a negative. Except that obviously this is bogus, especially since I just painted my dog this morning.
    Where do people get the ridiculous idea that a negative can't be proven?
    Because it has so far proved impossible for any one human to be cognizant of all existence, therefore no human can ever be certain that there are not existing things or conditions outside his or her knowledge, therefore no human can provide rigorous proof of the non-existence of anything.

    Consider: What if the earthly laws of physics are local to a specific region of space-time that the solar system happens to be in right now, and most of the universe is not in that region? Can you prove that this is not so?

    You can, of course, prove negatives that can be restated as strictly confined positives. But as a general principle, you cannot prove that something doesn't exist anywhere.
