    i can define a turing machine inside a (very complex) finite state machine. i can't do the reverse.
    <!--QuoteEnd--></div><!--QuoteEEnd-->
    That's not true. Turing machines by definition have an infinite read/write tape. There is no way of defining that inside of a machine with a finite number of states. A finite state machine is just a Turing machine without a read/write tape.

    In fact, there is no computation in the universe that we know of that a Turing machine cannot in principle duplicate. Finite state machines can't do very simple things like determining whether parentheses match. In fact, finite state machines are exactly as expressive as classical regular expressions.

    what if i define input as external stimuli and output as a reaction to the stimuli based upon the current state of the machine. also:

    If you can read back in what you write, then that is a Turing machine.

    then where's the disagreement? input and output are not part of the machine and don't have to be defined, we only need to have a state for turing operation and a set of substates to allow turing-mode processing

    The definition of a finite state machine includes the fact that it can't write. That's what makes it different from a turing machine.

Computation begins in the start state with an input string. It changes to new states depending on the transition function. There are many variants, for instance, machines having actions (outputs) associated with transitions (Mealy machine) or states (Moore machine), multiple start states, transitions conditioned on no input symbol (a null) or more than one transition for a given symbol and state (nondeterministic finite state machine), one or more states designated as accepting states (recognizer), etc. <!--QuoteEnd--></div><!--QuoteEEnd-->

    i don't see "not allowed to produce output" anywhere

    what stops me from using one or more of the states to produce human or machine-readable output?

    As I read that, it seems that a Finite State Machine cannot use its own Output as Input for a future transition. This does not prevent it from storing information, but does mandate that all stored information be stored in the choice of State. This means the storage capacity is inherently limited by the finite number of states available, making a FSM incapable of processing arbitrarily large amounts of data that exceed its available storage.

    From the way you've been talking, it seems that Turing Machines <i>can</i> process arbitrarily large amounts of data. Does this suggest that humans are not, in fact, Turing Machines, since we have limited data storage capacity?

    The general argument is that humans can read and write, and in particular, they can read what they write. It's pretty straightforward if you have the patience to step through the operations of a Turing machine and simulate it yourself, so it's clear that ignoring the physical constraints of running out of paper, we have at least the computational complexity of a Turing machine.

    The interesting thing I think is that no one has ever found a model of computation in the physical world that is more powerful than a Turing machine. (Note that by "more powerful" I mean that for A to be more powerful than B, there must be something A can compute that B cannot. This says nothing about the time it might take A or B to perform it, except that the running times must be bounded.) There are purely theoretical models of computation that are more powerful than a Turing machine, but the ones I'm familiar with require you to be able to compute with real numbers, and it's an open problem of whether anything like that can physically exist. It has been shown that certain abstractions of quantum physics are no more powerful than a Turing machine. In general, the term "computable" is defined to mean something that is computable by a Turing machine.

    That strikes me as a rather, well, useless version of free will. What is it good for if you can't alter the future?
    <!--QuoteEnd--></div><!--QuoteEEnd-->

    It's all a matter of perspective. Why be depressed that you can't change the future when you don't know the future to begin with? You can make choices, and the culmination of those choices are the future.

    Your first sentences miss the entire point. You can't just throw away determinism because 'we make decisions!'

    And describing what might potentially happen if determinism is true has absolutely nothing to do with it actually being true or not.

    I think that free will vs determinism is very tough. It seems right now that determinism should win, but I think it is definitely possible that some unknown emergent factor of intelligence lets us get out of that mess. Who knows!?

    Our intelligence was predetermined and worked its way out over the thousands and thousands of years of evolution. Our intelligent acts at any point are also predetermined by factors that lead us to interpret events in a particular way and to respond in a particular predetermined way.

    so you believe that the bible is the absolute truth and that god has set everything in motion and that god knows what will happen and all that jazz.

    if god knows what will happen then he knows what you will do and your "choices" are predetermined.
    if you have true freedom over your actions then god does not know what you will do and is unable to see the future and is not omnipotent.

    Ok, so obviously this is a derail, but: What good reasons do you have for believing the bible? Show me some evidence, tell me why I should believe. I don't think that basing any real decisions on faith is a good thing to do.

    I think you're missing out on real thinking when you use a very old text that was written by people who knew very much less than we currently do about the universe to make your decisions. You say it was written by God? Show me why I should believe that.

    I seem to vaguely recall that I once thought about the conflict between omnipotence and free will. I guess the only thing certain is that an omnipotent being would know whether there's free will or not. But would an omnipotent being have free will?

    Why am I not a Muslim or Jew? Because after using my brain, and looking at the evidence, I have decided that there is no god, and this goes for the Muslim and Jew god just as it goes for the Christian god. So I ask you again: Do you have any good reasons to believe? For everything in your life you need a reason to believe something, but I guess you don't need a reason to believe Christianity?

    I think you're confused about the definition of "omnipotent".

    Omnipotent is all-powerful, Omniscient is all-knowing. I happen to believe God has both qualities, but its entirely possible for something to be omnipotent without being omniscient.
