    >>Some problems simply cannot be resolved absolutely.

    Did I say CS can solve "all problems"? No. There's quite a big difference between computer science having insights for some philosophical problems and "all" philosophical problems, which you'd realize if you didn't constantly try to reduce my statements to an incorrect absolute.

    >>How would you make a decision in that instance which ends the debate?

    Personally, and this has nothing to do with CS, in this case (if it's the one I remember about a veteran writing to him about) I agree with Sartre. Both taking care of one's dying mother and loyalty to one's comrades in arms are commendable actions, and he can freely choose either of them.

    While I can see that an absolutist like you might have trouble dealing with truth values other than true or false, these concepts have only passing applicability in the real world. "It's hot outside" - tell me if that statement is true or not, AmiMoJo.

    Fine.

    Hard Determinism as a theory can be formulated as such (http://instruct.westvalley.edu/lafave/FREE.HTM):
    PD1: No action is free if it must occur.
    PD2: For any event X there are antecedent causes that ensure the occurrence of X in accordance with impersonal, mechanical causal laws.
    CD: No action is free.

    My proof of free will via the Halting Thesis:
    PF1: Free Will is defined as being true if Hard Determinism is false.
    PF2: If an action must occur via impersonal, mechanical, causal, laws, then this implies it is possible to calculate the state of the universe U1 at time interval T1 = T0+1 via the function U1 = simulate(U0).

    For example, we have a toy robot on a billiard table that either has a LED lit or unlit at any particular time interval. Via the simulate() function, we can determine if the robot will have the LED lit or not for any time interval T > T0.

    PF3: The robot also runs the simulate() function, and sets the LED to be the opposite of the returned result for the given time interval. (LED = !simulate(U0))

    CF1: Therefore it is not possible to calculate the state of the universe at any time in the future.
    CF2: Therefore no action "must occur" (i.e. PD1 is false).
    CF3: Therefore Hard Determinism is false.
    CF4: Therefore Free Will is True (via PF1).

    The philosophers are way ahead of you. The trouble with your method is that it only shows whether something is possible or not under one particular model of reality, the object-hierarchical model. If you show that it's possible under that model then fine, job done: it's possible. But if you show that it's impossible under that model you've not shown that it's impossible in general. And frankly the most likely outcome is that you can't work out how to do it but can't prove that it's impossible without sitting down with the philosophers and listening to their arguments.

    It depends on the philosophical argument being made. If they assume certain object relationships cannot exist, and one can show how those relationships are possible in compilable code, odd as it sounds, it explodes the argument.

    In Being and Nothingness, Sartre assumes there are only two types of objects: beings-in-themselves - things like rocks and trees - and beings-for-themselves... conscious entities, which essentially need other objects to think about in order to create themselves out of nothingness, recognize nothingness, and rely on other beings-for-themselves to establish identity. If you look at it from the point of view of a computer scientist, it takes on a really quite implementable model, which you can then discuss concretely without the froofery and meaninglessness of philosophical debate that so turned Wittgenstein off on the field.

    >>Mathematics is the foundation for philosophy

    Eh, kinda. Advanced logic is the foundation for a lot of modern philosophy, but Wittgenstein and the rest of the 20th century analytics were just responding to the tremendous success of physics at figuring shit out, and wanted to smear some of that patina on themselves. Well, logic has always been a part of philosophy (think Socrates and his syllogisms) but reading the Tractatus is like reading a modern computer science proof.

    Which isn't surprising, either, given that computer science is essentially applied philosophy in a lot of ways. (cf Bertrand Russell, etc.) If you've ever sat through a class where philosophers have sat there talking themselves in circles about how an object can't both be is-a and has-a at the same time, you (if you're like me) feel like leaping up and just telling them to fucking encode whatever paradox they're trying to create in a object hierarchy, and be done with it. I've long longed to write a book called "Computer Science has figured a lot of your shit out in practice, Philosophers".

    It does kind of bug me though, that a person who graduates with a degree in mathematics (which is a fairly difficult, hard-nosed subject) gets a wishy-washy BA degree, whereas a hippie with a degree in "environmental engineering" gets a BS, but ultimately I think there's a lot of problems with our current conception with categorizing things into "science" and "not-science". Economics and Climatology are very analogous in terms of what they do - gathering tons of data, running analyses on it, and projecting things out into the future, and both are essentially "empirical studies of the world about us" (i.e. a sort of base level of science, though with the testing, replication and confirmation bits left out), but we consider one to be a social science and another to be hard science. There's also a huge debate now over Anthropology, after the American Anthropology Association dropped "science" from its official bits.

The phase kinda-sorta lasted for about 40 years, though during this time, we gave Cuba independence, the Philippines later, and so forth.

I suppose you could make an argument for the Native Americans, but really what we're doing in Iraq and Afghanistan right now is much more typical for our country.

    If you don't understand why, let me break it down for you:
    1) If something has a long half-life, it's not very radioactive. You either need a lot of it to pose a hazard, or you can just ignore it. It's not like the uranium ore is contained in any way before it gets mined.
    2) If something has a short half-life, or you have a lot of long half-life waste, it's not waste, it's fuel. The problem with nuclear waste isn't the radiation, it's the heat it generates. Which is why India is looking to use all the waste heat it produces to drive a turbine and generate power.

    Or you can just put the MOX or whatever other products you get out of a reactor into a different reactor (ideally on the same site) that burns the 'waste', closing the fuel cycle. If you burnup 99.5% of your fuel, as the IFR does, then you put the remainder in a coffee can and throw it into a cooling pool on site.

    For most people, buying new isn't done because the numbers look good, it's because they want a new car. Status, keeping up with the Joneses, etc. I could give a shit.

    But for me, the cost analysis was a bit different. I own my own company, and am on the road all the time for trips to other cities to have meetings conduct tech workshops, etc. So when a car is a business expense, it mixes everything up. Off the top of my head (and I'm not an accountant, so I could be very wrong), the main differences are:
    1) You don't get mileage for your commute, but you do get them for business trips. So your average worker is kind of screwed over by the IRS, but for people that have multiple workshops every month in other cities, you get a pretty large tax write off for mileage.
    2) The mileage write off includes maintenance. So if you have an old car, you can't write repairs off as a business expense.
    3) However, new cars as a business expense get depreciated over 5 years (or 1 year in 2010, woot) so you get to apply the cost of the new car against your taxes - call it a third the price of the car back into your pocket.
    4) If your old car breaks down en route to give a workshop, you look unprofessional, and also don't get paid. My old car had 170,000+ miles on it from all my work driving.
    5) Certain new cars qualify for stimulus tax credits, which you don't get if you lease or buy used. The Altima Hybrid and Leaf both get these to make them more attractive, economically.
