Nothing groundbreaking to report here so far. I'm already convinced that I am my brain, and that dualism is bunk, and that we do not survive our own death. There has been some discussion of the neuroevolution of morality and mammalian caring, which is interesting to examine at the level of hormones and their receptors in the brain (specifically, oxytocin and vasopressin).
I was interested in Churchland's book (which I became aware of through here interview on The Colbert Report) because the study of neurophilosophy sounds so dang sexy. In the latter half of the book (which I have yet to read), I'm hoping for a little more in the philosophy department with regard to the broader implications of 'neuroexistentialism'.
