“Revolution in Thought: A new look at determinism and free will"

[pood]

Yeah, if hard determinism is true I had no choice to write what I wrote, and you had no choice to write what you wrote.

So?

Of course it is not true, so there is that.

Compatibilism is the argument that free will is compatible with determinism as Compatibilists define it to be . If the world is not deterministic, Compatibilism has no bearing on how the world works, which makes it practically irrelevant. The question then becomes, what is the nature of free will in relation to a non deterministic world, and how does this definition of free will relate to the workings of a non deterministic world with its random and/or probabilistic events.

If the world were not deterministic, then compatibilism would be irrelevant by definition. There is a sense in which we do live in a nondeterministic world--quantum indeterminism. However, we interact with reality at a level of events in which experience tells us that causality works and we live in a deterministic world. Moreover, there are ways of interpreting quantum mechanics such that determinism makes sense (e.g. Everett's Many Worlds Interpretation).

Accepting the paradigm of Determinism as true (which is may well not be), Free Will would be impossible, because the pre-determined act of seeming to choose between illusory alternatives is not an exercise of will. It is simply a programmed response.

This assumes that programmed responses are:

A) Simple; and
B) Lack freedom

A is certainly false, as any computer programmer can attest; B is highly questionable, and depends on what we mean by "freedom".

 

[bilby]

Stated differently, the existence of Free Will in its pure form depends upon (a) the existence of true “options” or “alternatives,” and (b) humans being capable of thinking (and acting) in a manner that is not 100% caused by prior activity that is outside their control.

I don't agree. Condition (a) is certainly present for most human decisions, as I think you'll agree, and so is of little import; But condition (b) seems unweildy and arbitrary.

Humans are quite capable of acting in a manner that is caused by prior activity that is entirely internal to themselves, and completely unpredictable in advance, even to themselves.

That may not be Free Will "in its pure form", but it waddles and quacks a lot like free will in its form as understood by, well, everybody.

I am not seeing how indeterminism has any bearing at all on free will, though.

Free choices are not random, any more than they are forced upon us by the external universe.

Free choices are chosen, not random; And they are chosen by internal and highly complex chaotic systems that are fundamentally unpredictable, just like the weather.

The brain is not a kind of supercomputer; It is an electrochemical system, bathed in an endocrine system that interacts with it in myriad ways, some fairly local and others systemic, with both positive and negative feedbacks. And Bilby's Law of biology applies: All statements about biological systems can be made more accurate by adding "... but in reality, it's much more complicated than that".
