I just read another question from this website about free will, decided to ask my own rather than comment on another. I have no formal education in philosophy. I almost want to ask this question from an inexperienced, uniformed position...
Without getting too heavily into references that I'd be unfamiliar with, why is it that existentialism isn't compatible with the idea of free will being an illusion?
I understand that one's world view doesn't have to fit into the philosophy mapped out by someone maybe centuries ago exactly, but in a general sense I think I agree with existentialism in that it is up to each of us to derive meaning from our experiences, and to find purpose in life. I also believe that we don't author our thoughts and are affected by external stimuli which shapes our bias and perception constantly.
Is this even a question? Is philosophy more the study of philosophers and interpreting their works, or generating new ideas based on those people?
