Very interesting post here from Peter Freed's blog Neuroself. His argument (the argument of his blog as well as of his article) is one I've forwarded here from a couple of other sources, including Hofstadter--there is no such thing as the unitary self (which many Buddhists have understood for quite some time). We appear to be composed of many selves, and our selves work in a kind of network (Borg, anyone?) both to produce the experience of individuality and the experience of community.
A question for my students: what would this theory suggest about the notion of artistic "voice"?
