If you wish to discuss free will vs determinism, go ahead. I like to discuss that too. — TogetherTurtle
Well then! I'm just going to take the lazy way out and post something I wrote for an assessment task a little while back. It's on point...

Power to The Puppets
Whether free will is compatible with determinism, and whether we can have either, both, or neither, is entirely dependent on our definitions.
Determinism has traditionally been defined as the theory that every event is uniquely prescribed by antecedent events. Thus, anyone with perfect knowledge of the universe at one point in time, of its causal laws, and sufficient computational power, can infer with perfect accuracy the state of the universe at all other points in time. The problem with this claim is that it is incompatible with quantum mechanics, which holds that at a quantum level, the universe is random.
Free will may be defined in such a way that it is easy or impossible to reconcile with determinism. The psychologist Skinner argued that since all behaviour is controlled by our biology and environment, what we are actually talking about when we talk about freedom is freedom from aversive forms of control. Hume defined as free all actions motivated by desires originating from within the person. There does not seem to be any problem reconciling either kind of freedom with determinism.
Kant, however, derided Hume’s idea of freedom as “the freedom of the turnspit,” and claimed that in order to be truly free, the will must be an “uncaused cause.” This is clearly incompatible with determinism. Similarly so Descartes’ definition of freedom as the “ability to do or not to do something,” and his claim that “the will is by its nature so free that it can never be constrained.”
But the kind of freedom philosophers like Descartes and Kant demand is not only incompatible with determinism: it is incompatible with any naturalistic theory of the mind.
From Beyond
Suppose a mind is a physical process. Whether that process is deterministic or random makes no difference: the mind is whatever that process makes it. Hence so too are all its choices. Replacing the freedom of the turnspit with the freedom of the quantum random number generator renders it neither more nor less the puppets of physics.
Not surprisingly, the theories of both Kant and Descartes are heavily reliant on things beyond science’s ken. Descartes saw the mind as comprised of an entirely non-physical kind of substance, while Kant posited a “noumenal” realm in which the mind could be free. But such approaches are unparsimonious to say the least, and create many problems.
One is that we have not so much reconciled free will with an orderly (be that order deterministic or probabilistic) universe as posited an entirely new universe or substance with no order at all, save perhaps for that which the will self-imposes. Another is that we are now faced with the problem of explaining how the different types of substances or realms interact; and of producing the evidence of this interaction, or else explaining its absence. Finally, we must somehow sidestep neuroscience, leaving us with what we might call “the free will of the gaps.” These are serious problems, so the arguments of the likes of Descartes and Kant need to be compelling.
Descartes first argued as follows:
1. Descartes could conceive of having no body, but could not conceive of having no mind
2. Therefore body and mind have different properties
3. Therefore the two must be different things.
But our conceptions of a thing cannot be properties of the thing itself, because if they are, then Donald Trump (very stable genius) cannot be Donald Trump (mania sufferer/malignant narcissist).
Closely related is Descartes’ second argument:
1. If you can clearly and distinctly conceive of something it is possible
2. You can clearly and distinctly conceive of your mind being distinct from your body
3. It is therefore possible your mind is distinct from your body
4. If two things are possibly distinct they are distinct
5. Therefore the mind is distinct from the body.
It is again possible to show by example that this argument form leads to false conclusions:
1. I can clearly and distinctly conceive of the morning star as distinct from the evening star
2. It is therefore possible the morning star is distinct from the evening star
3. If two things are possibly distinct they are distinct
4. Therefore the morning star is distinct from the evening star.
Yet both are the planet Venus.
Kant saw the existence of free will as implied by and inseparable from our rationality. But consider an artificial intelligence (AI) capable of simple reasoning. Now consider the chip on which that AI runs. We do not say that the AI is able to reason because it causes the chip to transcend the laws of physics. Rather, we know that the AI functions precisely because the chip obeys the laws of physics.
But if reason implies not other realms, but working hardware, it is no less reason for the fact. If it enables us to apprehend our environment, consider alternative courses of action, and implement those choices that appeal to us, this surely represents at least a kind of freedom.
We may decide what we decide because we are what we are, but this does not mean our own cognitive processes are not making decisions. It only means that there are also other things deciding us. As with the AI and the chip, our rationality exists not despite their determinations, but rather, because of them.
Conclusions
Determinism, as traditionally defined, prescribes a perfectly predictable universe that is clearly at odds with contemporary physics. Whether we consider the probabilistic order of quantum mechanics an alternate form of determinism, or an alternative to determinism, is a matter of definitions. Whether or not we get to keep determinism depends on which definition we pick.
In any kind of orderly universe, without recourse to something above and beyond that universe, we are all physics-puppets. But the “above and beyond” comes with fundamental problems with no clear solutions, and the arguments in support of its existence are less than compelling. It does not seem to carry its weight.
Whether it is possible to reconcile free will with our status as physics-puppets depends on our definition of free will. If we insist on a mind that has the potential to be an uncaused cause, which is to say an ultimate cause, then no such reconciliation is possible. If, on the other hand, we can settle for proximal causation, in which free will means only that the physical world has been arranged in such a way as to create a being with the potential for rational decision-making, then yes:
There is such a thing as a free puppet.
