I think if I read it now, I would have more trouble with it, since what I remember of the storyline (the shock treatment, the weird mental illness/identity loss of the protagonist) and the vague recollection I have of the philosophy (was it heavily Kantian? Wasn’t he always going on about a priori this and that?) doesn’t seem too cool now.

Bu I enjoyed it when I was younger, I read it in between high school and college.
