The comment goes:
One of the emerging conclusions of neurology is that the idea of a single "true self" must be discarded. We have no indivisible soul; we have multiple systems acting independently, thinking different things -- ... Those systems may be in tension -- base hormones are telling me I want a cookie, even when my frontal cortex is labeling the desire as unwise. Tension demands resolution, but this demand need not be met. Sustained tension can be either productive -- the relation between parts becoming part of a whole self -- or destructive, in which case growth or healing will seek to resolve the tension one way or the other, by making one system ascendant over the competing systems.
To "I think, therefore I am," I respond "I think many things, and therefore am many things."
