  1. strong predeterminism

  2. weak predeterminism

  3. no predeterminism

  1. Jul 15, 2004 #1
    The following quotes are from http://www.etymonline.com .

    destiny - c.1325, from O.Fr. destinée (12c.), fem. pp. of destiner, from L. destinatus, pp. of destinare "make firm, establish" (see destination). The sense is of "that which has been firmly established," as by fate.

    destination - 1598, "act of appointing," from L. destinationem (nom. destinatio), from destinare "determine, appoint, choose, make firm or fast," from de- "completely, formally" + -stinare, related to stare "to stand." Modern sense (1787) is from place of destination, where one is "destined" to go.

    fate - c.1374, from L. fata, neut. pl. of fatum "thing spoken (by the gods), one's destiny," from neut. pp. of fari "to speak," from PIE *bha- "speak." The L. sense evolution is from "sentence of the Gods" (Gk. theosphaton), subsequently "lot, portion" (Gk. moira, personified as a goddess in Homer), later "one of the three goddesses (Clotho, Lachesis, and Atropos) who determined the course of a human life."

    fatal - c.1374, "decreed by fate," from L. fatalis "ordained by fate," from fatum (see fate); sense of "causing death" is c.1430. Fatality "disaster resulting in death" is from 1840; fatalism appeared 1678 as the philosophical doctrine that all things are determined by fate; fatalist in the general sense of "one who accepts every event as inevitable" is from 1734.

    The following quotes are from http://dictionary.com .
    destiny –
    1. The inevitable or necessary fate to which a particular person or thing is destined; one's lot.
    2. A predetermined course of events considered as something beyond human power or control: “Marriage and hanging go by destiny” (Robert Burton).
    3. The power or agency thought to predetermine events: Destiny brought them together.

    fate –
    1 a. The supposed force, principle, or power that predetermines events.
    1 b. The inevitable events predestined by this force.
    2. A final result or consequence; an outcome.
    3. Unfavorable destiny; doom.
    4. Fates Greek & Roman Mythology. The three goddesses, Clotho, Lachesis, and Atropos, who control human destiny. Used with the.

    Is there such a thing as destiny? Is there such a thing as fate? In this short essay, we will explore these issues.

    First of all, to fix our definitions, we will define destiny as the inevitable or necessary fate to which a person or thing is destined. Since this definition is self-referential, as well as a reference to fate, we will add that destiny is a predetermined course of events. Fate is the supposed force, principle, or power that predetermines events as well as a final result or consequence, i.e., an outcome. Using this definition of fate, we see that the definition of destiny becomes this: the inevitable or necessary final result or consequence, i.e., an outcome, to which a person or thing is destined. We suppose further that destiny is the inevitable or necessary final result for a person or thing in accordance with predetermination.

    The question then becomes this: are events predetermined? Are all events, some events, or no events predetermined? In the case that all events are predetermined, let this be called strong predetermination. In the case that some events are predetermined, let this be called weak predetermination. When no events are predetermined, let this be called no predetermination.

    Either we have strong predetermination, weak predetermination, or no predetermination. In the first case, the answer to the first question will be yes and in all other cases either a qualified or an unqualified no; likewise for the second question above.

    A preliminary result is this: if an event is predetermined and involves the choice of a person (or conceivably a thing), then that person (or thing) can not know in advance what the outcome is. To show this, suppose that an event that involves the choice of a person (or thing) is predetermined. To arrive at a contradiction, also suppose that the person (or thing) whose choice that event involves can know in advance what the outcome is. Then the person (or thing) could simply choose to change the outcome going against the predetermined outcome; this contradicts what it means to be predetermined and, therefore, the person (or thing) can not know in advance what the outcome is.

    We proceed to assume we have strong predetermination and see what results we can obtain from this assumption. This case can be ruled out immediately by considering a person dropping a ball on the ground. If all events are predetermined, then what the person does with the ball is predetermined. Either the person drops the ball or the person holds on to the ball. Since this event involves the choice of a person, and it is predetermined, that person can not know in advance what the outcome is. This means the person themselves can not (not just “does not”) know whether they will drop the ball or not; this is absurd. This absurdity implies that not all events are predetermined. Thus we have our second result: we do not have strong predetermination.

    To establish that we don’t have no predetermination, let us consider the event that a person correctly solves the equation “x+5=2x.” We see that a person has no choice, when done correctly, but to discover that x=5 (modulo equivalent answers such as 5=x). This outcome was determined before the person solved the equation and, therefore, it was predetermined. This shows that at least one event is predetermined.

    Since the choices strong/weak/no predetermination are exclusive, and we’ve ruled out the first and last cases, this means we have weak predetermination. Some events are predetermined and some are not.

    It isn't necesarily predetermined that they get the answer x=5. They could have absolutely no algebra skills and write nothing. They could make a huge blunder and divide both sides by 'x' wrongly thinking that will leave 5=2 (which doesn't make very much sense). Were the question to ask them to find 'x' they could do as a friend of mine once did: circle 'x' and then write "he's just not trying any more". Just because there's one correct answer doesn't mean a person has to acheive that answer. Mind you it is true that anyone with the most basic algebra should be able to get that one right.

    Weak predeterminism would more likely apply to events that are resistant to small changes. The life of a sun or the end fate of the universe are two examples but even then weak predeterminism only really dictates that certain events will occur since there can always be small discrepancies in how a major event plays out. If predeterminism is to exist then it is more likely that everything be completely pre-destined.

    the argument in the middle goes against completely predestined:
    this uses the result obtained previously which is this:

    There's a difference between predeterminism and the following of laws. Drop a ball off a roof, it will fall. It's not predetermined to fall. Once released, the force of gravity, combined with those of air resistance and wind, act upon it and the ball reacts by falling. Gravity is a law of nature.

    Mathematics is the code of nature. the equation "x+5=2x" yields the answer x=5 because nature disallows any other answer. If this was predeterminism, then that opens up the possibility that another answer could pop up, depending upon whatever power chooses for the predetermined answer. But this does not happen. x always equals 5 in this equation (mod 5) because that is the only logical answer. I could write down an infinite list of equations such that x=5 solves them all. Does that mean that something predetermined an infinite amount of equations? not only that infinite set, but an infinite set of infinite sets with an infinite amount of answers. this is ridiculous.

    All things are determined by the laws of physics. There is no free will. The current state of the universe dictates what the states to follow will be. There is no room for possibility with the equal-and-opposite, cause-and-effect laws by which all interactions take place...which is why ideas like heaven and hell and revenge and judgment are illogical.

    Dissisent Dan:
    I think we can all set aside the old traditional myths without too much difficulty. What I wonder is, how do you explain being an aware, cognitive personality for only .00000000000000000000000000001 percent of the whole of physical existence?? ( I may have missed a few zeros).

    Logically, this doesn't make sense. when we look at the world, everything cycles and renews itself. Why not beings?

    Firstly, you can't say, "Logically, this doesn't make sense," and be correct. You are making an inductive argument, not a deductive one. Therefore, you cannot make a claim as to whether or not it is logical. You can make a statement as to whether or not it is likely.

    Secondly, I don't see what cycling and renewing has to do with a small percent of "existence" (matter and energy are what I presume you are referring to) being aware, cognitive personalities. Consciousness is a very complex (there is a staggering number of synapses in even the simplest brains) and fragile (guess which comes out in one piece when an animal and a boulder collide?) phenomenon.

    You left out one critical alternative, that of relative predetermination. Demonstrably, whether one views something as predestined or not depends upon the context. Even the meaning of these words depends upon the context in which they are used.

    Why are you all so complicating?

    we're in a system, sort of like dissident dan said, and we are limited by our environment's and our own possibilities.

    that's all.
  11. Jul 26, 2004 #10
    Why is this in need of explaining except for in the spiritual (non-physical) sense? I have seen you post something similiar to this before olde drunk and while I feel it is an interesting point I don't see any support for it. Maybe you should be incredibly grateful that you exist at all. Maybe we are all just really "lucky" to be concious beings in a universe such as our own. I for one feel privileged that all prior events have led to my conciousness at this moment.

    I never said the ball was predetermined to fall. You may want to re-read what I wrote.

    Predetermined to me means determined before the event. x=5 was determined before the event of myself solving x+5=2x today.
  13. Jul 26, 2004 #12
    What law of physics states that when I solve x+5=2x, I get x=5? This is an aside because I already know that not everything is determined by the laws of physics; consider this a rhetorical question.

    Not everything is predetermined. Re-read my argument on why everything can't be predetermined. If it is predetermined that I will drop a ball, then I can not know that I am about to drop a ball. Not just do not know but can not know. If I can know that I "will" drop a ball, then I can simply choose to not drop the ball thus it wasn't predetermined that I dropped the ball.

    Besides that, what evidence do you have for your claims?
  14. Jul 26, 2004 #13
    Interesting idea. Please explain.
  15. Jul 26, 2004 #14
    It is determined by the laws of physics. The laws of physics dictate the synaptic interactions in your brain that led to the typing of "x=5".

    That is an argument against knowing the future, not against the future being predetermined.
  16. Jul 26, 2004 #15
    I'm not talking about the typing of "x=5" I'm talking about the solution to x+5=2x. What law of physics dictates that the solution is x=5?

    No it actually is against the future being predetermined. Re-read it and the original post and maybe you'll figure out what I'm trying to say.
  17. Jul 27, 2004 #16
    Well, the laws of math, of which I consider the laws of a physics a manifestation, dictate that. "x=5" is a truth, but it's not some "thing" that exists.

    I know the argument well. If you do not drop the ball, then it was predetermined that you would make that decision.
  18. Jul 27, 2004 #17
    How do you know that?

    If it's predetermined then I can't know what the outcome is. If I knew the outcome, I could go against the outcome. Do you agree?

    Predetermination ? Are we predetremined ?

    On a plane, the triangle that defines that plane equals the triangle inequality theorem.

    If our minds use two parts. Like Q & A. Then we use the triangle inequality theorem. ? < ? & A

    That theorem says we are determined to have a answer. So for your dropping rock question, a answer already exited.

    It was not determined at all, it just is. Nothing chose it to be 5, except you when you wrote the equation down. You plan for x to be 5 once you write down "x+5=2x". without context (the equation), x is just some arbitrary constant, letter, number, or whatever. But once you write out the equation "x+5=2x", you have chosen (in the now) x to have the assigned value 5. but i could equally write down an equation at the same time "x+3=2x" and have an answer x=3 at the same exact time you have x=5. thus, x is infinite. x is not predetermined by some "force". it is just planned, when writing down some sequence of signs and numbers.

    What do you mean by "determined?"

    dictionary.com defines "determine" as follows:
    Definitons 1, 2, 3, 7, 8, and 9 all point to the following being a true statement:
    "I determined that x=5."

    That x=5 is a solution to x+5=2x has been done before; hence the prefix "pre" in predetermined.

    It was predetermined that x=5.

    I agree that it just is, as well. It was predetermined and it just is. It just is predetermined.
