Having just listened to the above by Fyodor Dostoyevsky on Librivox while cross stitching, I will comment that free will seems to be what the author thinks drives us more than any one object of that free will. Man does not want to feel trapped even into doing the right thing. His description makes autonomy almost sound like obstinacy because of man’s aversion to, like a robot, only being able to choose what is rational or in his own best interest. He will purposely do the irrational and harmful just to show his freedom to choose.  He hasn’t gotten into the pleasure/pain scenario. I wonder if he will in the second part. Unless he thinks that it is subordinate to the ability to choose in that it is pleasurable to do the forbidden just because it is forbidden.
