[Will the real Humpty Dumpty please sit down] From: Rich Rosen pyuxd!rlr > Again, you assume that because you use the rational path (e.g., rather than > the biochemically instinctive path), employing what you call rational > evaluation, you are engaging in acts of "free will".

You *are* freer to choose a rational path (given that you do choose one) than those who take an instinctive path are to "choose" that path, because you can represent the options and evaluate them. Simply put: rational actions are chosen; instinctive ones aren't (unless part of a larger context in which rationality operates: I rationally choose to "let myself go" sometimes). > You make a distinction between them (and there IS a difference in the > methods AND [sometimes] the results), but they are functionally equivalent.

No, it's the same as free will just because the term means "having a certain type of advanced decision making mechanism". I do think that human reason has qualitiative advantages over most other animals', but if not, the difference of free will between us and them is just one of degree. >> Apparently you and Sargent are suffering from attachment to a paradigm (in >> the ordinary sense, not T.S. Kuhn's) of free will as some mysterious "ghost >> in the machine" with the ability to make decisions ex nihilo. > But the very notion of free will implies freedom to choose a decision path > regardless of one's surroundings, one's chemical make-up, etc. ^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^ BULL MANURE!! The "very notion" implies no such thing. Your paradigm of free will does, and you are confusing your paradigm with the "very notion". Compare your statement above with: "But the very notion of free will implies an ability to choose regardless of any ghost-in-the-machine". What makes your statement any more plausible than this? Is it because the whole idea of the "ghost in the machine" is that the ghost is supposed to be *you*? Ah, but -- you and I agree -- there is no ghost, and -- I contend -- the chemicals ARE *you*; to say "there's the chemicals of Rosen's brain" and to say "there's Rosen" are two ways of describing the same thing. Free will definitely does NOT mean an ability to choose regardless of the way one is, for then, who would be doing the choosing? Therefore, IF the chemicals are all there is to *you*, then your chemical make-up is NOT one of the things to include in your "regardless of" list. > Which, of necessity REQUIRES the "ghost in the machine", the external > agent. It is not a part of the definition, it is a consequence of it. Challenge: find an ordinary language user (not a philosopher, theologian, or such) whose use of the term 'free will' *logically implies* this "consequence". > I guess my "mistake" here is that I don't equivalence rational evaluative > capabilities with free will. Your argument has still given me no reason > to do so. Are you simply using a word or term the way you like ... Here's my argument again: >> Agency (having free will) consists in being able to choose among >> alternatives -- which raises the question how one chooses, and the >> answer is by evaluating alternatives. This in turn involves the use >> of reason, of having a conception of a norm and being disposed to >> adopt a consistent, best justified set of norms. Where's the hole in the argument? Is the problem that my definition does not capture all the connotations of the term? Probably not, but no helpful definition of a vague concept could. My definition *does* capture what's important about it -- the varieties of free will worth wanting. [Aside: _The varieties of free will worth wanting_ is the subtitle of Daniel Dennett's book _Elbow Room_ .] As Dennett points out, the concept of free will is "essentially" one we care about, i.e. it is something that is (supposed to be) worth wanting. > Rationality is a human-made description of a process.

"Rational" has a narrower meaning than that. It may be a vague word, but you can't stretch it that far -- talk about Humpty-Dumpty-ism. > It seems ironic, Paul, that you, who castigated me for looking "too deep > to the root cause", now claim that it's invalid to say that things are the > same "at a very general level of description". You're misreading me on purpose, right? I did NOT castigate you for looking "too deep to the root cause", but rather for looking ONLY at the "root cause" when both high-level (macroscopic) and microscopic descriptions are accurate. I did NOT claim it's invalid to say things are the same at a very general level of description; I implied that it's wrong to *stop* there. If you want to reject a distinction -- as you wanted to reject my distinction of rationality between the processes in human brains and processes in rivers, etc. -- you must examine *all* levels of description. A distinction is valid if it is valid on *at least one.* > You cannot justify logic with logic. Yes you can. (By showing, e.g., that it is truth-preserving.) > ...

Prove it "TO THEM"! If by that you mean "so that they accept it", then the fact that we can't prove anything to someone who doesn't use logic, doesn't show that we can't prove it. I can't prove anything "to" the severely brain-damaged either, but that's THEIR problem, not a problem with using logic to justify anything. > You cannot seem to look at a possibility of a system of belief outside > of reason and logic.

I am going to try a simpler version of Paul's argument. Rich can try to find the problem with this one. What is logically wrong wiht the assumption that ``free will'' [defined as the ability to make choices and thus self-determine certain events which have an effect on one's life] like ``language ability'' is a ``power'' that manifests itself in human beings during their lifetime? Why does there have to be a ``ghost in the machine'', or, alternately, no ability to effect changes by choice in one's life? That I started out as an undifferentiated cell zygote that did not have language ability does not mean that I had to stay that way -- why is ``free will'' any different? Laura Creighton utzoo!laura

From Rich Rosen: Gee, this is funny. Am I assuming that "all things are knowable" (I never said that) when I refer to things we don't have enough information about? No, when you are referring to those things, you are not (necessarily) assuming that. What I am assuming is that there are certain things which are not knowable. Why does the world exist? Why is Plank's constant *this* value and not *that* one? Why aren't there more stars? Why is there a force of gravity anyway? These are all examples of questions whose answers (ignoring direct revelation from God, say) are not knowable. There may be no reason for any of these. There may *be* a reason for all of these. But, whatever the answer is, it seems clear that we won't ever know it. Or are YOU assuming something when you *assert* that there ARE (!!!) some things that it IS simply IMPOSSIBLE to ever know? I don't know if that's true, so I keep seeking and learning. You assume that it is true, so what do you do? Ah, I get to stop wasting my time with a certain class of questions. Do you stop at a certain point and say "the rest I will picture the way I like because we can NEVER know this?" Sure I do. All the time. The thing to remember is that I have yet to meet a single person who does not do this. What I do not ever lose track of is that these things are things that I have modelled, rather than things that I know are true. So far I haven't needed to build a model of why there is gravity at all -- but I have had to build models of other things. It's funny because you're doing exactly what I've been accusing so many others of doing. Looks like you're not that different, and perhaps your belief systems should be classified with the same name. :-? Looks like you are back to being omniscient and knowing what I am doing again. Before you go out and claim this again, I think that you had better get a better understanding of what it is that I am doing. I am not claiming that any models I build are true in some absolute sense. I don't even have any firm opinions about the existence of ``absolute truth''. What I do claim is that my models are useful for getting something done. Almost all of the time this implies that my models have to be consistent with reality as I perceive it. There are times, though, when even that does not apply. If I am debugging circuit boards I catch myself thinking that ``the current goes along here, and then down there'' and so on and so forth. Thinking that ``the electrons vibrate'' is more consistent with reality as I perceive it, but even that is a model. Electrons aren't things. Shall I try to think of them as locuses for particular behaviour? Better, but shucks, it just isn't incredibly useful. I am willing to put up with inaccuracies for the sake of utility. This brings one back to Byron Howes on religion. Suppose you consider all religions as models of reality which people use to get things done. The question then is, why do people pick different religions? Presumably because they want to get different things done -- or the same thing done in different ways. Inherant in certain religions is the belief that ``This is the ONE and ONLY religion which is TRUE in the ABSOLUTE SENSE''. Other religions do not have this belief. I do not think that you have ever grasped the implications of this, or you would not be asking me if I go out and ``believe whatever I would like'' -- because in a very real sense I have been claiming that *everybody* does this *all* of the time. This is another aspect of the Christian/Materialist debates which others (including Christians such as Byron Howes) may find ludicrous. Certain Christians are claiming the absolute truth of the existence of God and the Bible. You deny the absolute truth of this (or at least, that they have demonstrated this to be the absolute truth). But you are *both* wedded to your idea of an absolute truth -- there is one, and it is important to know whether God is a part of it or not. Since this is one assumption that I do not make except when it suits me (rememeber your search for assumptions, Rich) I find the whole thing rather unusual. The answer does not only wash, it cleans and brightens and softens as well. I'm not seeking a justification or reason for the way the universe is, precisely because I don't assume that it was designed to be that way. We have no reason to speculate on design plans or reasons here. Unless we assume a designer. Rich, you lose. I can speculate on anything I like without assuming a designer. Why does my cat have blue eyes? Getting an answer to that does not necessarily assume a designer -- to understand that one requires knowledge of genetics. We have wonderful reasons to speculate reasons for why the universe is a certain way -- this is exactly how one goes about learning anything. What you are saying is ``unless oen assumes a designer, one is not likely to get any answer to such questions''. Right. The answers to such questions are unknowable. There may even *be* no answers to such a question. Now you have contradicted yourself. Laura Creighton utzoo!laura if you only believe in things that you understand, you'll *still* suffer -- and get killed by the first dangerous thing that you refuse to believe in becuse you don't understand it (yet).

"Camelot!" "It's only a model." You make a valid distinction here, but all words are just sounds and etchings that represent models of reality. Do they do so accurately or not is the question?

There is a difference between the absolute truth and words we use to represent the absolute truth. By modeling our words and concepts more closely to reality instead of dogmatic assertion, by being flexible in receiving new hard information and acting on it, we achieve a better picture. By the way, is it an absolute truth that there's not absolute truth, Laura? >> The answer does not only wash, it cleans and brightens and >> softens as well.

The genetics you mention is a "how", not a why, as someone else pointed out. A "why" assumes a reason as chosen by a causative will of a designer. Only in the context of a universe assumed to have such a designer does such a question even mean anything. The "why" is not just "unknowable" in the absence of a designer, it's non-existent. All you'll get are "how"s. -- Life is complex. It has real and imaginary parts. Rich Rosen ihnp4!pyuxd!rlr

"Seems clear" is an assumption, too. But remember that there is no answer to a "why" in the absence of a directed causative will. Thus to ask and to expect a certain answer is to be presumptive in the extreme. I don't think that a direct causitive will is implied. If somebody came up with a unified field theory, a fair number of ``whys'' could be answered. If the mechanics of universe creation were known, the answer to that ``why'' could be known as well, even if there is no directed causative will. There may be a reason for all of these but I just can't go off to a lab and build a few universes to test out any of my theories. This is too bad. Note that saying that these are ``hows'' doesn't change the problem. There are some ``hows'' which I can't know either. Again, this is too bad, but I am not going to lose sleep over it... Ah, I get to stop wasting my time with a certain class of questions. You mean the "why" questions I was referring to above? For the same reasons? I mean the why questions I brought up above, yes. But I don't think that I am not spending time on them for the same reasons. I don't care how presumptuous I am -- I just care about whether I can get any results. "Camelot!" "It's only a model." You make a valid distinction here, but all words are just sounds and etchings that represent models of reality. Do they do so accurately or not is the question? Are they used erroneously? Ah, ``erroneously'' is a funny word. Do you mean ``are they used to represent things that have no basis in reality''? I think not, or else you would have to reject ``the current goes down here'' as being erroneous. Do you mean that they ``are used in ways that are not useful?'' The problem with this definition is that what you find useful and what other people find useful may be entirely different. Do you mean ``are used by people who forget that they are models of reality and confuse them with reality itself?'' Gee, that is my position, but I brought this one up weeks ago and you were real upset when I accused you of mistaking your concepts with reality. What do you mean? Interesting notion about models. The questions then revolve around the erroneousness of certain dogmatic models. Again, what is ``erroneousness''? The confusion of a concept with reality again? This is another aspect of the Christian/Materialist debates which others (including Christians such as Byron Howes) may find ludicrous. Certain Christians are claiming the absolute truth of the existence of God and the Bible. You deny the absolute truth of this (or at least, that they have demonstrated this to be the absolute truth).

By modeling our words and concepts more closely to reality instead of dogmatic assertion, by being flexible in receiving new hard information and acting on it, we achieve a better picture. By the way, is it an absolute truth that there's not absolute truth, Laura? Rich, go back and read. I did not say that there is no absolute truth. I did not say that there is one either. I hold no opinions on the subject. I use the notion of absolute truth when it suits me and I don't when it does not. The concept of absolute truth is another concept, and, as such I use it when I find it useful. Laura Creighton utzoo!laura

How do you know that further advances >in science won't answer questions which you now consider unknowable? Part of the problem here is that two *different* meanings of the question "why" are being used. The form used by scientists essentially asks "what set of circumstances caused/causes this?". The philosophical question is harder to paraphrase, at least without using the word "why", since it is questioning the inner meaning of the Universe. So the speed of light is "determined" by Maxwells equations, this is only the "scientific" why. It only moves the problem back step. Why are the parameters of Maxwell's equations what they are and not something else? Why do they take te form they do and not some other? In short you have *not* answered the *real* question being asked. It is *this* sort of why question that Laura is claiming is unanswerable, at least from the perspective of science. And she is right, because science has outlawed such questions. -- Sarima (Stanley Friesen) {trwrb|allegra|cbosgd|hplabs|ihnp4|aero!uscvax!akgua}!sdcrdcf!psivax!friesen or {ttdica|quad1|bellcore|scgvaxd}!psivax!friesen
