T-Rex: You guys!
T-Rex: Let's assume the universe is deterministic!!
T-Rex: And if that's true we're no more responsible for our actions than a computer is for executing code. We have no choice in what happens to us, and if you set up the universe in the exact same way we'd make the same choices and the exact same things would happen. Free will is therefore an illusion! Like a computer, WE ARE NOT RESPONSIBLE FOR OUR ACTIONS.
Utahraptor: Geez. Let's assume the universe is indeterministic then!
T-Rex: Even better!
T-Rex: Then things can happen randomly with no event responsible for causing them. And anything random (which includes every decision we make, unless you want them to be deterministic!) you can't be held responsible for, so therefore AGAIN we're not responsible for anything we do.
Utahraptor: Huh.
T-Rex: Anyway, LONG STORY SHORT:
T-Rex: I have it on good authority that somebody tooted just now but SADLY, we have no-one to blame
