Neuroscientific evidence requires a monistic understanding of brain/mi
nd. Truly appropriating what this means confronts us with the vulnerab
ility of the human condition. Camus's absurd and Tillich's despair are
extreme expressions of a similar confrontation. This crisis demands a
type of courage that is consistent with scientific truth and does not
undermine the spiritual dimension of life. That dimension is not a se
parate substance but the process by which brain/mind meaningfully wres
tles aesthetic symbols, religious faith, and ethical affirmation. The
validity of these activities does not depend upon human autonomy bur i
nstead upon the fact that they exist. Furthermore, they constitute the
self, which Dennett calls a ''center of narrative gravity.''
