Three possibilities come to mind:
Is there an evolutionary purpose?
Does it arise as a consequence of our mental activities, a sort of side effect of our thinking?
Is it given a priori (something we have to think in order to think at all)?
EDIT: Thanks for all the responses! Just one thing I saw come up a few times I’d like to address: a lot of people are asking ‘Why assume this?’ The answer is: it’s purely rhetorical! That said, I’m happy with a well thought-out ‘I dispute the premiss’ answer.
Because determinism is too depressing for small minds.
Really making a strong argument by calling people dumb. If you were as smart as you think you are, you would realize the value of empathy.
Your response was an emotional one, which does not mean my argument is incorrect. However, it does reveal your insecurities.
If you think you can accurately diagnose my insecurities from one comment, I don’t know what to tell you. My response evoking an emotional response in you does not make it in itself emotional. I wrote it sitting on the toilet because I was bored at work, not because I felt that it was especially important.
“No u” lol ok
Careful, your response quality is slipping. You don’t want to put even a little effort in?
