By free will I mean the ability to have done otherwise. This, I argue is an illusion. What ever the reason is that makes one choose A rather than B will make them choose A over and over again no matter how many times we rewind the universe and try again. What ever compelled you to make that choise remains unchanged and you’d choose the same thing every time. There’s no freedom in that.

I also don’t see a reason why humans would be unique in that sense. If we have free will then what leads you to believe that other animals don’t? If they can live normal lives without free will, then surely we can too, right?

I don’t know where our curiousity or the desire to help the less fortunate comes from. Genes and environmental factors most likely. That’s why cultural differences exists too. If we all just freely chose our likes and not-likes then it’s a bit odd that people living in the same country have similar preferences but the people on the other side of the world are significantly different.

Also, have you read about split brain experiments? When the corpus callosum is severed which prevents the different brain hemispheres from communicating with each other we can then with some clever tricks interview the different hemispheres separately and the finding there is that they tend to have vastly different preferences. Which hemisphere is “you”?
