@philosophyminis: For all of the many wonders of physics, its conclusions are pretty depressing. Because #physics teaches us that nothing is beyond its iron fist. Nothing and no one can operate outside of the universal laws of nature. The sway of the leaves, the breeze on your face, and the nerves in your skin are all bound up by the laws of #science And if your entire #brain and body is just another puppet to physics, what does it mean to say that you have #freewill? This is what Laplace talks about with his demon. #Laplace asks us to imagine a being of such supreme #intelligence that it knows every possible fact about the universe, it knows everything there is to know about every particle there is. Now, if physics can offer a full account of how these particles interact and behave, Laplace postulated that this #demon could use its intellect to predict every future event with 100% accuracy. If a demon knows everything that exists and also knows all of the laws of physics, what's to stop it from knowing how everything will be? The demon will know that when a butterfly flaps its wings, it'll cause a hurricane over there. It'll know how a sea bed becomes a mountain, and it'll know how a planet will eventually give rise to carbon-based lifeforms. The demon will see the cells making a foetus, a foetus becoming a boy, a boy's brain learning from a closed world, and that boy becoming a man who is talking to you right now. And it was always going to be this way. So, in the #scientific world, and with Laplace's demon hovering about, what does it actually mean to have free will? #philosophy

Waste Time :
Sorry, this is drawing upon the determinism of classical physics. Quantum, our most successful theory, has little determinism, which is what bothered Einstein so much. Laplace preceded Quantum theory.

It is important to live under the assumption that we have free will. The contrary will lead to depression & widespread failure to act.

If the future is determined, nobody is responsible for their actions.

Everything except for the causal agent that was before the Big Bang

But 'I' (consciousness) do not live in time, space or causality - I am solely the knowingness In which they appear. The body-mind is totally bound, wholly determined by genetics and conditioning.

Even if we do not have free will, we have no choice but to act as if we do.

We don’t have free will because of our genetics as well as we are born with gene that defines each one of us

To say that a deterministic world disproves the possibility of free will, means that this will is not deterministic in itself. Why we should suppose that?

Not if our brain is the physical observer that let‘s collapse wavefunktions. The Observer might be seen as pre-realistic und is before time, but ranges into collapsed pysical reality. So we are both:

More like natural laws than an iron fist. A finite, but boundless universe is not such a harsh reality.

The old clockwork universe. We know the universe actually isn’t like that. QM puts a spanner right in the heart of determinism. We even use that fact in quantum computing.

Besides the animalistic urges we humans have and being on autopilot i think we do have free will but we don't use it all the time, I think free will is mostly in our thoughts and less in our actions.

Foreknowledge doesn't necessarily mean predetermination. Just because someone or something can see the future doesn’t mean they are causing the future.

Physics isn’t deterministic but I agree we don’t have free will. It has some significant implications for stuff like morality.

Well, I think it is a bit more complicated than that. First, we do not know exactly what conciesness is and how it appears. As we can see, animals are not fully self aware of the world they live in.

A full account or perfect prediction is impossible . The Heisenberg uncertainty principle is an example that you can know one thing about an atom or another thing, but not both at the same time.

Laplace was before Heizenberg. 100% accuracy does not exist in physics with the quantum mechanics uncertainty principle.

A big problem with such problems is definitions. How do u define free. That’s why Wittgenstein insisted physical language biases our attempts to philosophy
