Tautology isn't just a good idea, it's also the law. From the "Berkeley Sure Is Nutty" Department: "In a philosophical effort to come up with a city law that no one could ever break, conceptual artist Jonathon Keats wants Berkeley to legally acknowledge Aristotle's law, commonly expressed as A=A."
Maybe they could legislate that everything be stamped with this.

What will the legal punishment be for saying that A = stupid artist?
There is a misdemeanor fine of $0.001 for breaking this law. I'm not sure if simply saying something would be considered a violation though, it would probably have to be proved in court that A=stupid artist.

Keats explained that a simplistic law challenges society's notion of what laws are, why they are made, and why we follow them.
Or maybe this law is the perfect example of Berkeley politicians overstepping their boundaries, creating invasive and pointless laws in response to all problems: actual, perceived, or even unfathomable. Maybe passing a law isn't always the best solution, eh Keats?
Also, I hope no one is planning on doing any experiments with quantum physics at Berkeley.

I'm about 99.99% sure I went to college with Keats - how many philosophically minded people who wear bow ties and are somewhat insane live in San Francisco? Seeing as Matt Walker also went to the same school, and Alex George taught there at that point, I would put that closer to 100%.
Anyway, if it is John, he was - among other things - a noted conservative on campus. Once during his freshman year he got dead drunk, passed out, and his roomates wrote "666 I am a Democrat" on his forehead with some kind of indelible marker. Very nice guy though.
Also, I don't he's principally a conceptual artist: he edited SOMA and wrote a novel (which I heard is quite good, with some steamy sex in it).
My concern with this law is that as people try to break it - and you know they will - they will either (a) develop split personalities, (b) be forced to develop new and more irritating philosophical systems which people will try to talk to me about at dinner, or (c) rewrite the basic rules that govern the universe and turn this reality into a Buffy-like hell dimension.

I'm assuming that's Keats' entire point. The local gov't is wasting so much time on piddly spit. Keats is basically calling the entire law system a sham. Not just Berkeley's local government, but the entire concept of government in general. This is very much the equivalent of a college philosophy professor pounding on a table for an entire lecture screaming "This is not here!" Keats conceptual art argues that Law as modern day society accepts it doesn't really exist. It's a subjective construct that has been devised, a series of *things* we subject ourselves to because we fear the alternative of chaos, but Keats is arguing that even something as simple as "A=A" doesn't apply in the subjective reality humanity has created for itself.

The only thing I remember him wanting to ban was paperback books, which he blamed for the downfall of Western civilization.
Of course maybe he's hoping the people of Berkeley reject the proposal, proving that Berkeley not only rejects nuclear weapons and various ecologically harmful activities but actually rejects the fundamental basics of logic and rationality as well.
As a way to spend a day, putting on a bow tie and irritating people on Telegraph Ave. actually has a fair amount to recommend it. Beats television at least.

I don't know.. maybe someone can, but all the proofs I've ever done have assumed identity. I think that's as safe an assumption as you can make to build a system of logic on. I'd sure hate to live in a universe where it wasn't true. Well, I would or I wouldn't, tautologically speaking.
Also, nitpick-wise, I think the law says not that "The statement I am making absolutely equals the statement I am making," but rather that "The statement I am making is the statement I am making", because of something I vaguely remember being called the Indiscernability of Identicals, two things can be equivalent but not identical.

"A=A" isn't about statements (unless you were to say a given string of phonemes is identical to itself, or something like), it's about objects.
Pick an object -- a rock, say. Can you conceive of any possible way that THAT rock could not be itself? No. THAT rock could not be some other rock, or a tree or something -- if it were, it wouldn't be THAT rock.
As for the speed of light, whatever speed it is, it is THAT speed, and not some other speed. The fact that scientists may have thought it was a speed it wasn't doesn't mean that it actually was a speed it wasn't.

I'll make an amateur suggestion --
They may be referring to Kant (who has been credited with founding modern philosophy). My guess is that they are referring to Kant's self-proclaimed "Copernican revolution" in philosophy, in which Kant argued that one's knowledge of (for example, a chair) Chair A (the phenomenal A, or Ap) is not identical to Chair A in itself (the noumenal A, or An). Kant argued that one's knowledge and understanding require the use of categories which are present a priori in the mind.
In contrast, realists would hold that we just comprehend things as they are; that is, one experiences an object (Chair A) as itself, just as it is, without this experience being determined a priori by mental categories.
So for Kant and after, Ap != An.

At the beginning of this thread a couple of people mentioned quantum mechanics, but as far as I can see it doesn't raise any new problems for tautologies.
I think the people are probably confusing different conditions for a theory of meaning. Presumably tautology is a necessary condition for any such theory, because if "A" isn't "A" then names are useless. Quantum mechanics adds additional conditions - measurements associated with non-commuting operators are mutually exclusive, for example (are there others?).
But there's nothing in what I've just said that means that quantum mechanics somehow invalidates tautologies. "The position of particle p at time x" is still "the position of particle p at time x". The additional constraints on a theory of meaning imply that "the position and velocity of particle p at time x" is not well defined, but that doesn't raise any new questions for tautologies. To use a famous example, "the king of france" is "the king of france" just as much as "the position and velocity of particle p at time x" is "the position and velocity of particle p at time x" - both are problematic for theories of meaning, but both are equally valid as tautologies.
Incidentally, there's nothing special about quantum mechanics in raising questions about meaning. Special relativity, for example, also requires that the user qualify observations (you need to specify a four vector in an inertial frame to identify an event).
Also, I don't think "a shoe is either brown or not brown" is a tautology - it's not a simple assertion of identity as it appeals to the law of the excluded middle.
And finally, it would be very difficult to find a denial of this law in any meaningful philosophy because it is so fundamental to any theory of meaning. Your best chance is to look at more "mystical" philosophies (ie those that don't rely on logic). While the comment about Kant is a decent reflection of his ideas (afaik), it's not connected with tautology as much as theories of perception - theories that take things like tautology for granted. If tautology failed to hold then even Cartesian doubt becomes meaningless - if "I" am not necessarily "I" then how can "I" meaningfully questions what "I" think?
(All imho - I'm no philosopher. I suspect no-one'll ever read this, it being a late contribution to the thread. But if someone does spot a silly mistake in what I've said I'd like to know...)

I think the people are probably confusing different conditions for a theory of meaning. Presumably tautology is a necessary condition for any such theory, because if "A" isn't "A" then names are useless. Quantum mechanics adds additional conditions - measurements associated with non-commuting operators are mutually exclusive, for example (are there others?).
But there's nothing in what I've just said that means that quantum mechanics somehow invalidates tautologies. "The position of particle p at time x" is still "the position of particle p at time x". The additional constraints on a theory of meaning imply that "the position and velocity of particle p at time x" is not well defined, but that doesn't raise any new questions for tautologies. To use a famous example, "the king of france" is "the king of france" just as much as "the position and velocity of particle p at time x" is "the position and velocity of particle p at time x" - both are problematic for theories of meaning, but both are equally valid as tautologies.
Incidentally, there's nothing special about quantum mechanics in raising questions about meaning. Special relativity, for example, also requires that the user qualify observations (you need to specify a four vector in an inertial frame to identify an event).
Also, I don't think "a shoe is either brown or not brown" is a tautology - it's not a simple assertion of identity as it appeals to the law of the excluded middle.
And finally, it would be very difficult to find a denial of this law in any meaningful philosophy because it is so fundamental to any theory of meaning. Your best chance is to look at more "mystical" philosophies (ie those that don't rely on logic).

ps On the shoe question, I'd say it's an analytic statement, not a synthetic one. But if I understand correctly, there's no reason for all analytic statements to be tautologies (although they can be reduced to tautologies by appeal to, for example, the law of excluded middle).
