Ok, Yerg mentioned this subject yesterday in another thread in SLR, so I thought I should to make a thread for that here...
The 19th century classical physics still said that everything that happens in the universe is pre-determined by the laws of physics. They even imagined a hypothetical creature called "Laplace's demon" that was so intelligent that it could predict all the future events in the whole universe, basing its prediction on physical laws...
The quantum mechanics that was developed in early 20th century is not that deterministic, it says that when mechanical systems are in the microscopic scale, their state develops deterministically as long as no one is observing them, but as soon as an observation is made, there are only statistical probabilities of what state they are found in... I'm a physicist myself and I have a job in the university, and this is familiar to me, but it's probably difficult to describe the concept of quantum indeterminacy to a lay-person.
Now, the subject of this thread is, how to apply the determinacy/indeterminacy to human behaviour(a human is a mechanical system, too)... If all human behaviour were deterministic, there obviously would be no freedom of choice, everything would be pre-determined... There would be no moral choices, even the terrible deeds of murderers and pedophiles could not be blamed because they were pre-determined by physical laws...
Obviously people need indeterminacy, because if there were no moral decisions, because of physical laws, then there would be no moral motive to even find out what those very laws are! All human behaviour is based on supposing that you can make either right or wrong decisions...
I don't speak native English, and it's difficult for me to discuss a subject this abstract coherently in this language, but I hope you got my point... What do you think, is the universe deterministic or indeterministic?
