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.

    I think its because we’re only just now coming to terms with the fact that we’re simply a collection of desires, the culture we were born to and stories we tell ourselves. In keeping, we had to have a story to tell ourselves and free will existing is the more compelling of the two.

    I don’t think there’s an evolutionary purpose. To me, we just became far more self aware than our limited knowledge of the world we find ourself in could cope with and its more of a coping mechanism than anything else.
