If i get presented the arguments and evidences for evolution, and i reject it, did i have a choice to accept or reject it based on the rationaility of the argumnts? Or did i reject it simply because of the way the chemicals in my brain reacted to the external stimuli (the evidences)? That is, under determinism, i am merely a passenger.
Both. As I said, you've erected a false dichotomy and you continue to argue as if semantic epiphenominalism were entailed by materialism. Choosing to accept or reject it rationally is just looking at the behavior of the chemicals in your brain from another perspective. Rationally evaluating things is changing the chemicals in your brain, and vice versa. There is no conflict because they are the same thing.
How can it be both?
If i throw you off a cliff, you will be subject to the law of gravity, you will fall...No matter how much you scream, kick, wave your arms around, you have no control at all as to what is happening.
You are merely a passenger in this example, subject to the laws of physics that were determined all the way back from the big bang.
Do you agree?
Now, how is this any different in any other aspect? All the chemicals in our brains are merely reacting to the external stimuli.
If i read the evidences for evolution, it is merely the chemicals in my brain which is reacting to the external stimuli (evidences) and i come to the conclusion i come to simply due to the the way the brain reacts to the external stimuli....
I/me am merely a passenger in the process just like you falling down the cliff...i am just like you arent in any position but to obey the laws of physics we are subject to....
I would reject evolution not because of the rationality of the arguments, but merely because of the way my brain has reacted to the external stimuli (evidence)
