You (and everyone else) certainly can choose to do what they want at any time, but in the end they end up doing whatever it is they do because the chemical reactions in their brain compele them to do so. Determinism isn't about people not being able to think about decisions, but that their thoughts are all driven by chemical reactions, which were caused by other things in the world, which had their own causes, etc. Basically, in order for determinism to be incorrect, there needs to be a way that people generate thoughts/decisions that is not based on a reaction in the brain. I'm not the best at explaining either so i'm sure i'm doing a shitty job of it but hopefully you get my point =/
No, because in order for determinism to be false there has to be some unseen force that allows people to make decisions based on something other than the nerve impulses/chemical reactions in their brain. It isn't really about things being "predetermined", it's more of the idea that there is no other possible reality than the one that has occured.
No, according to determinism (the most logically sound argument) there is no free will. After the Big Bang, everything that has occured in the world is a physical/chemical reaction caused by previous conditions (reactions) and thus the world as it is is the only world there could ever be and nobody could have done anything different. This is called "causal determinism" (http://en.wikipedia.org/wiki/Determinism) and the main argument against it is that people have a "free will" to choose what actions they take. There are some people that believe determinism is compatible with free will but it doesn't make a lot of sense to me (how can you have free will if there was no action you could have taken other than the one that you did take?) I just wasn't sure how you could reconcile determinism and luck, or why you believed in free will.
I was reading the argument about luck in sports and felt compelled to ask you, what is your argument against determinism? It seems to me that a fiercely antireligious person like yourself would have a difficult time accepting a mystical "free will" force, so there must be some other argument that you have, right? Feel free not to answer or whatever, I was just curious.
We have a smogon server for minecraft, and in order to sign up to get on it we've had people fill in a form with their smogon username and minecraft username someone put their smogon username as yours and their minecraft username as "imawanker", which we didn't believe and found it that account does not exist. I just wanted to be sure that it truly wasn't you.
