and, i don't think that's such a crazy suggestion either.

we don't have much say over how our heart beats, or even if  it beats. and, we call this an autonomous nervous system.

but, we can sit and do math homework in our underwear if we want.

it's just a simple way to understand that not all decisions are the same: sometimes we have a choice, and sometimes we really don't.

rejecting descartian dualism means that most real-world decisions would exist in a mixed state, between something like digestion and something like math homework. we can't completely undo our physical realities. but, we can direct it in some way or another. and, how much of that is real and how much of it isn't depends on how purely intellectual the decision actually is.

you can see that with something as simple as going grocery shopping. you know you shop differently when you're hungry, right? and, that kind of mixed up way to look at it is getting to the right idea: it's very complex to separate, to the point of probably being impossible in most scenarios.
