    Free will
In summary: I agree with you, the problem is most likely unsolvable, at least by any human cognitive powers. in fact, whether i really have free will or just the illusion of free won't even affect my decisions--either way, i think I'm thinking for myself.

But I’m asking you, it’s your definition after all…..

FYI, libertariansim is the opposite of determinsim. Libertarians think we are not
totally constrained by just the same things determinists think we are totally constrained by.

microphysical indeterminism (if it exists) applies to computers as well as humans – would you therefore suggest that computers also have free will as you have defined it?

It is a necessary but insufficient condition. The other factors include
consciousness, rationallity, etc and are not ususally in dispute.


what does evolution or revolution have to do with free will or constraints? Evolution and revolution can take place in a completely deterministic and constrained environment lacking in any kind of free will as you have defined it.

They have to do with the "high level" argument for determinism.
OC it might be the case that only microphysical determism is true,
and allows for the appearance of novelty at the social/cultural level,
as you say. And that...ta-daaaaa!... is exactly why I cited the need
for microphysical indeterminism as well.

But you do have to measure them if you want to then claim that one is greater than the other

Nope. Have you ever done any maths ? The kind involving x's and y's ?

We started with you defining free will in terms of no constraint from “external circumstance”. I asked you how you would define an “external circumstance”. Instead of answering you start spouting about Libertarianism and Determinism? Seems you are avoiding the question.

Tournesol said:

You did not include consciousness or rationality as prerequisite properties in your definition of free will, and they do not fall out as implied properties. Would you now like the chance to revise your definition?

That does not answer the question. I still maintain that evolution and revolution can take place in a completely deterministic environment. You suggested that somehow a deterministic environment would somehow prevent evolution or revolution. I am interested to know how you think that could possibly happen (since I think it is false).

Educate me. Show me how you can demonstrate that x is greater than y (apart from just assuming it) unless you put values against x and y.

Tournesol said:

I grant you that in the context of “free will”, environment is normally an external circumstance and we should be able to make most decisions free from environmental constraints. However I think genetics is bit more tricky (I can imagine instances where behaviour is tightly constrained by genetic factors).

Are you suggesting therefore that only human beings (endowed with consciousness and rationality) can possesses this thing called “free will”?

The cultural environment one is brought up in may condition one to think in certain ways, I agree, but it is no more of a constraint on free will than is the physical environment (which we saw above is an external circumstance that should not completely prohibit free will).

I see no reason why free will is a necessary pre-requisite for either evolution or revolution. Evolution in particular can be thought of as a purely deterministic process. And revolution can be simply (for example) a catastrophic change in the social order within a (hypothetical) purely deterministic society bereft of free will. But I would be happy to see examples of where you think free will is a necessary prerequisite for either evolution or revolution.

moving finger said:

Tournesol said:

which is an assumption (or definition) about the relationship between x and y, not a demonstration that x is greater than y.

This whole question arose because you asserted that “If an event were more cause than effect, its conscequences would be unpredictable in principle” which begs the question “how do you measure whether an event is more cause than effect”. As far as I am aware cause and effect are not quantitative parameters in any meaningful sense, ie it is not possible to equate or compare them and say for example “ohhh, here the cause is double the effect” – but I am open to this latter statement being proven wrong. Simply asserting “let y = x/2” does not prove it wrong.

Libertarians (so I understand) do not accept that the whole universe behaves deterministically, for they maintain that the human mind (or the innermost regions of the brain) present an exception. According to Libertarians, a person's mind can itself cause that person to perform a particular action when that person chooses so to act, without the choice itself having any antecedent cause. The usual unbroken chain of cause and effect is thus broken, and when a person exercises his or her free will, a new chain is initiated by the act of will itself. However, the supposed mechanism for initiating a new chain of cause and effect by the mere act of free will remains a mystery.

In some ways, this seems reminiscent of Descartes' dualism (the thinking self can act independently both of causation and of the physical self).

Would you agree this is an accurate view of Libertarianism?

No, it is a straw-man. Libertarians do no believe in a rigid causal chain
to which the human brain is an exception. They think strict determinism
is false in general (which is a necessary condition for FW which only becomes
sufficient in the presence of various other factors such as rationallity and lack of external constraint).

Free will? Does that mean that if I choose to be happy then I actually am? If I decide to love my girlfriend then I actually do? I feel that I have some choice in the logical processes, but I have very little choice in my own emotional processes. LOL, It is actually easier to control other peoples emotional processes than my own. It seems to me that we are both in control of our own will and subject to the will of others.

In statistics it is easy to predict what a large group of people will do under certain circumstances. It is almost impossible to predict what an individual (a stranger to you) will do under those same circumstances. A cloud of gas will expand in a completely predictable manner, but a particle of that gas could go almost anywhere. I would suggest that we do indeed have a will, but that it is not free at all. There are restraints and limitations on it beyond our control.

P.S. What would the possibility of time travel mean for free will?

Hmmm. Why does one need to be rational to possesses free will? If I possesses free will as a rational being, and I then somehow “lose my wits” and start acting irrationally, are you suggesting that I have also lost my free will?

Does it also follow that if we can at some stage endow machines with consciousness, that they could also start acting with free will?

With respect, this is rubbish. Truth by stipulation is only valid where there is logical preceding reasoning which supports the stipulation. You can no more claim that an unsubstantiated y=x/2 than I can claim that the morning sun will be blue. Both are unsubstantiated assertions. What you need to do to support your assertion that a system can exhibit more cause than effect is to demonstrate how cause and effect can be quantified, which you have not done.

Tournesol said:

In this case, you KNOW from prior data that there are two hydrogen atoms per oxygen atom in water, and it is this knowledge which legitimises your “stipulation”. This is what I mean by logical preceding reasoning. Simply stipulating (without substantiation) that there are two hydrogen atoms for every oxygen atom would be simply a guess, and worthless (even if true).

To address your question straight forwardly... i have stayed longer sicne more information is needed on the thought process of beings such as moving_finger... go to special relativity, and look up the discussion on GR and time travel... me and figner had an 8 page long discussion on time travel and free will... i basically took him to school with my 300 year advanced knowledge on the subject, and it caused him to come down with a rather pecuilar case of amnesia. I would advise all to read it who question free will. When the human mind can fathom the 4th dimension, evolution will take place.

We do not usually attribute moral responsibility to crazy people, and

What you need to do to support your assertion that a system can exhibit more cause than effect is to demonstrate how cause and effect can be quantified, which you have not done.

It's a conceptual relationship derived from determinism and predictability.

In this case, you KNOW from prior data that there are two hydrogen atoms per oxygen atom in water, and it is this knowledge which legitimises your “stipulation”. This is what I mean by logical preceding reasoning. Simply stipulating (without substantiation) that there are two hydrogen atoms for every oxygen atom would be simply a guess, and worthless (even if true).

But it is "prior knowledge" that in a deterministic universe, everything is predicable. Everything else follows logicaly from that.

You have told me what Libertarians do NOT believe, can you tell me what they DO believe? This is the more important issue.

They believe that FW, as previously defined, does exist, and is incompatible
with determinism, which is therefore false.

Huckleberry said:

Assuming that your "choice" to be happy then leads to the state that "you are happy" then - of course. Happiness is a state of mind.

What you have to understand is that "choosing" something and "deciding" something does not then automatically lead to that "thing" taking place. I can "choose" that I wish to jump over the moon, but I cannot actually accomplish that feat. I can "decide" that I want to hold my breath for 20 minutes, but the mere fact of me deciding that does not enable me to do it.

Huckleberry said:
If I decide to love my girlfriend then I actually do?
As explained above, if you are capable of loving your girlfriend, and if the act of deciding to love her leads to you loving her, then you actually do.

Huckleberry said:

Perhaps you just need to "know yourself" a little better. With practice and with self-knowledge and self-understanding, you CAN control your emotions and emotional processes.

Huckleberry said:

I humbly suggest that is simply because you need to practice.

Huckleberry said:

Please define "will"?

Huckleberry said:

No. It is easy to predict what they are "likely" to do. This is not the same as what they "will" do.

Huckleberry said:

Wrong. It will expand in a statistically predictable manner, but not completely predictable.

Huckleberry said:

Please define what you mean by "will" in this context.

Huckleberry said:
What would the possibility of time travel mean for free will?
If time travel is possible, and if there is only one universe, then the only way to ensure self-consistency (ie not being able to go back and "change" the past) is if the world is super-deterministic.
But free will CAN be compatible with determinism - it depends on how you define free will. What kind of free will are you talking about?

Nope. A deterministic universe is NOT necessarily predictable, and (most importantly) it is IMPOSSIBLE to predict the future of even a deterministic universe from WITHIN that universe. If the universe is deterministic, the only way to predict the future is to stand “outside” of 4D spacetime (eg as God). Any being within (and interacting with) 4D spacetime cannot reliably predict the future (it comes back to those wonderful self-referential causal loops again).

Earlier you seemed to be supporting the compatiblist idea that an agent is free
if they (proximately) cause their actions, even if those causal events are themselves entirely

I wonder if you can explain how this Libertarian free will can arise any other way (apart from the so-called “straw man” explanation that you seemed to dislike)?

The straw-man explanantion has it that only humans behave indeterministically. Libertarians do not need to assume this, and QM
indicates that indterminism is in faxct widespread.

What you call the high-level argument is false.
If by “low-level argument” you mean “quantum indeterminism”, then indeterminism (if it exists) simply gives rise to indeterminism – it is not a source of free will, it is a source of randomness.

Tournesol said:

Quantitative means : Can be measured. If you believe that magnitudes of cause and effect can be quantified then please explain how this can be done, to allow us to conclude (for example) “ahhhhh, this shows more cause than effect”. You have not shown this, all you have done is make oblique references to algebra.

Tournesol said:

Such predictions (whilst possible in principle) are also in principle inaccessible to the beings existing within the universe.

This kind of free will is entirely compatible with determinism (see my post #35 in this thread)

Which is why I said “depending on how you define free will”. I think you will find that Libertarians would not accept that everything is deterministic, because 100% determinism would not allow them to have the kind of free will that they seem to wish to have.

Tournesol said:

Indeterminism is not a source of free will, it is a source of randomness. How can randomness allow Libertarians to recover the kind of uncaused causal chain that they need in their philosophy?

Humans are indeterministic and have Fw because they can also think rationally.

Unstable nuclei (eg) are indeterministic and do not have FW because they cannot think rationally.

Yet another spurious "nothing to do with" ?

Which does not imply that if you are irrational you do not have free will!

Yes. If you are insane, you are irrational, if you are irrational, you are
not morally accountable, and that you are not morally accountable
means you have no FW.

(again, just so we know what the question was : You asserted that rationality was a pre-requisite for free will, which I challenged.

YOu think unstable nuclie have FW ? Nothing does ..? Eveything does ..?

Instead of answering my challenge, you are trying to say that this has something to do with sanity and moral responsibility……… are you just trying to confuse things?)

Sanity, moral accountability and rationality are all part-and-parcel
of the same issue.


What you call the high-level argument is false.

You mean that people aren't determined by culture (etc)? Or
if they were, there would not be the absence of evoution-and-revolution
that I suppose.

If by “low-level argument” you mean “quantum indeterminism”, then indeterminism (if it exists) simply gives rise to indeterminism – it is not a source of free will, it is a source of randomness.

That is your opinion. Mine is the contrary:-

Quantitative means : Can be measured. If you believe that magnitudes of cause and effect can be quantified then please explain how this can be done, to allow us to conclude (for example) “ahhhhh, this shows more cause than effect”. You have not shown this, all you have done is make oblique references to algebra.

You do not have two measure two quantities to know they are equal.
Although my argument is concpetual, it is not "qualitative" in a way
that excludes quantativity.

Such predictions (whilst possible in principle) are also in principle inaccessible to the beings existing within the universe.

SO what ? Are you saying that our inability to predict quantum effects is
due to our presence in the universe ?

This kind of free will is entirely compatible with determinism (see my post #35 in this thread)

Nope. Determinism means you are entriely constrained by circumstances
prevailing before you were born.


Which is why I said “depending on how you define free will”. I think you will find that Libertarians would not accept that everything is deterministic, because 100% determinism would not allow them to have the kind of free will that they seem to wish to have.

As I have been saying.


My explanation (that you called “straw man”) said nothing about indeterminism. Where did you get this from?

I was referring to this exchange:-

moving finger said:
Libertarians (so I understand) do not accept that the whole universe behaves deterministically, for they maintain that the human mind (or the innermost regions of the brain) present an exception. According to Libertarians, a person's mind can itself cause that person to perform a particular action when that person chooses so to act, without the choice itself having any antecedent cause. The usual unbroken chain of cause and effect is thus broken, and when a person exercises his or her free will, a new chain is initiated by the act of will itself. However, the supposed mechanism for initiating a new chain of cause and effect by the mere act of free will remains a mystery.

In some ways, this seems reminiscent of Descartes' dualism (the thinking self can act independently both of causation and of the physical self).

Would you agree this is an accurate view of Libertarianism?

T said:
No, it is a straw-man. Libertarians do no believe in a rigid causal chain
to which the human brain is an exception. They think strict determinism
is false in general (which is a necessary condition for FW which only becomes
sufficient in the presence of various other factors such as rationallity and lack of external constraint).



Indeterminism is not a source of free will, it is a source of randomness. How can randomness allow Libertarians to recover the kind of uncaused causal chain that they need in their philosophy?

Randomness automatically gives you uncaused causes. The question
is how it impacts rationallity, which is what I address in my essay.

Tournesol said:
a) argue for microphysical indeterminism

b) point out that the suppsoedly determining macroscopic influences
we grow up with (culture etc) have not, historically , prevented all
kinds of evolution and revoultion. If we are all determined by ourt upbringing,
back to the year dot, why aren't we still in caves ?

An interesting essay, but the essay does nothing to defend your point of view, it simply attacks a particularly "myopic" view of determinism, hence the essay actually demonstrates very little that is useful in terms of the debate.

If you have a particular belief or philosophy, I humbly suggest that what you need to do is to show how it works, and to defend it. In other words, if you believe that indeterminism gives rise to free will, you need to show how it does this, what the consequences are, what happens if we remove indeterminism, etc. You do not do this, hence it is difficult to take your argument seriously.

I still claim that indeterminism results simply in indeterministic outcomes, it does not result in “free will” (whatever that may be). You do not show how indeterminism results in "free will" in your essay. With respect, if you wish your argument to be taken seriously you need to show not only how indeterminism can result in your kind of “free will”, but also that the removal of indeterminism would then necessarily also remove that same "free will".

Free will requires lack of complete constaint, by definition.

Lack of complete causal constraint is equivalent to indeterminism.

Indeterminism is therefore necessary but insufficient for FW
(it also needs to be established that it is not inimical to rationality).

This is the error. You equate your feeling of "I" with total lack of causation. But this is wrong.

The “I” simply “is”. It exists.

The “I” is a source of causation.

We accept the “I” as existing, and as being the source of causation.

Whether the “I” in turn has causal precedents (or is causally random) is irrelevant.

Naïve intuition suggests to us that the “I” must be somehow uncaused, must be independent of prior causes. But why should this be so?

Why does it make any difference whether the “I” is caused or uncaused? What matters is only that the “I” exists in the present time, that the "I" is at least partly unconstrained by present and future events, and that the “I” is responsible for causing future events.

I submit that whether your “present day” “I” can be traced back to prior historical causes or not is totally irrelevant. All that matters IS your “present day” “I”, and not from whence it came.

And I certainly do not see how it helps to suggest that “random indeterminism” may be partly responsible for the source of your “I”.

Indeterminism is therefore irrelevant for the feeling of individuality that humans have.

I disagree. This depends on one's definition of free will.
Lack of complete constraint implies indeterminism, but you have yet to show how either "lack of complete constraint" or "indeterminism" generates free will (ie the definition of "free will" as "requires lack of complete constraint" may be inconsistent).
I am coming round to the conclusion that our feeling of free will actually requires no complete present or future constraints, but is irrelevant to whether or not we are constrained in the past.

Tournesol said:

I agree with this statement. But where the fault lies is in assuming that either indeterminism or lack of causal constraint can generate free will.

Tournesol said:

I would say that our feeling of free will is not dependent on either historical determinism or historical indeterminism.

I like very much a simple poem that a fellow-member submitted recently :

One ship sails East, and another sails West,
with the very same winds that blow.
Tis the set of the sail, and not the gale,
which determines the way they go.


In other words : The directions of the ships are not so much dependent on the wind, but more on the set of the sails of each ship. The ships are indeed masters of their destiny, but this says nothing about whether the set of their sails has prior causal determination or not.

The error that Libertarians make is in assuming that free will must somehow be associated with an uncaused past.

In response to some of the ideas in the above link :

Tournesol said:

This is a source of error. There is no evidence that such a thing is possible, and in believing this, Libertarians are deceiving themselves. Determinism would say that "if the circumstances are the same, the choices will be the same".

Tournesol said:
That is, that alternative possibilites were actually available, they have a positive power of choice, since they bring something of their own to a choice, they have ultimate responsibility, unlike computers whose 'choices' are always attributable to external and prior factors.
What evidence do you have that such alternative possibilities were actually available, except as theoretical possibilities within the mind of the agent?

Tournesol said:
We cannot attribute UR to computers because one is always substitutable for another, the individuality of the computer makes no difference.
Why should individuality make any difference to UR?
If computers cannot be the source of UR, what IS the source of UR?
Indeterminism?

The Libertarian Illusion

Libertarians often emphasise what they consider to be the two (and related) key features of their philosophy of free will:

Alternative Possiblities (AP), the idea that there is a genuine (ie unconstrained) choice available at a given time

and

Ultimate Responsibility (UR), also known as origination, the idea that there is a genuine sense in which an agent is the originator of its voluntary acts, and therefore bears responsibility for them.

Let us study these features in more detail.

The power to make choices is in fact compatible with determinism – a choice after all is simply “taking two or more inputs and producing one output” – and demonstrably deterministic agents like computers can certainly make such a choice (even though such a choice may be a constrained choice).

Obviously (assuming determinism is true), two identically programmed computers will always make the same 'choice' under the the same circumstances, and (given sufficient knowledge of the programming and data) the 'choice' of each computer is always predictable. The Libertarian would say that the computer brings nothing uniquely “of its own” to the choice, that it does not bear “ultimate responsibility” because its choices are always attributable to external and prior causative factors. But this statement is in fact meaningless (what does “of its own” actually mean?).

The above assumes determinism is true. If we now introduce indeterminism, such that two identical computers do NOT always make the same choices, and these choices are NO LONGER predictable, does that mean these computers suddenly “bring something of their own” to the choice, or that they suddenly “bear ultimate responsibility” for their choices?. How can the introduction of indeterminism render “irresponsible” computers suddenly “responsible”? Clearly it cannot.

Indeterminism is therefore a “will-o-the-wisp” when we are looking for the source of ultimate responsibility. Indeterminism cannot be a source of ultimate responsibility.

Libertarians believe that having chosen, they could have chosen differently under the very same circumstances. In other words, if precisely the same circumstances were to be repeated, the outcome could have been different. This scenario is clearly incompatible with determinism. The only way that identical circumstances can give rise to different outcomes is if indeterminism is true. For this reason, many Libertarians embrace indeterminism. But we have just seen that indeterminism does not endow ultimate responsibility.

Somehow, a Libertarian interprets the introduction of indeterminism as meaning that “they bring something of their own to the choice, they have ultimate responsibility”, but Libertarians fail to explain how “something of their own” can arise from an “indeterministic cause”, which we have already seen has nothing to do with ultimate responsibility.

Since the last four post have been by you, and I hope we have become friends enough that I can tease you a little, I though I would break your chain of posts with:

Would you please define what you mean by "genuine choice." How can we have a meaningful discussion if you use undefine terms?

PS glad you liked my poem (post 56)

Hehehehe - Well spotted!
As an attempt at a "weak" defence, I actually copied & pasted the offending phrase from a website referred to me by Tournesol at : http://www.geocities.com/peterdjones/det_compat.html

Now, I would not have chosen the phrase “genuine choice” myself, because I believe there is simply choice, sweet and simple. Yes, that choice can be constrained (inevitable) or it can be unconstrained (evitable), but to my mind both kinds of choice are genuine. What I think the Libertarian who wrote those words actually means by “genuine choice” is probably “uncosntrained choice”, but that is only my guess.

I plead guilty to using ambiguous terms and not defining them.

Any luck on defining GFW?

Cheers

MF
