I am a total hobbyist, but this question bothers me for a long time.
My line of thought is, if there is a collection of rules for which any given event would result in a set outcome with no deviation possible (this is what all forms of determinism have in common according to wikipedia, if i have understood it, maybe i am wrong here already), why should anything happen at all? Meaning why would there be anything if nothing would be mutable in essence, wouldn´t that make existence itself obsolete?
Edit: As the question of what I mean by "Why should there anything happen at all? Why would there be anything if nothing would be mutable in essence, wouldn´t that make existence itself obsolete?" came up often, I´ll try to explain that part a little more in depth.
Keep in mind the first two answer where given before the edit.
Assume the universe is deterministic in the sense that:
- for every event x there is an outcome y, such that when x happens the outcome y has to happen
- and the event x is the only way the outcome y can happen.
Then x is sufficient and necessary for y, hence y is sufficient and necessary x. Then x and y are essentially the same event, the only way to destinguish x and y would be the order in which x and y took place. This should also hold for every universe which is deterministic, so especially for the universe in which only x and y happen. But in the universe where only x and y are happening we couldn´t possibly uphold that order of events, since x and y are equivalent and we wouldn´t know which one happened first. So if we drop 1. there wouldn´t be anything happening at all and if we drop 2. we are not deterministic anymore. Hope that makes it a little clearer. Feel free to point out any flaw in that argument.
I´m sure this is flawed, but please can someone explain why? Sorry for my bad english.
