Ontological Coherence

Alan Mann in his very provocative and often controversial book Atonement for a Sinless Society says, the typical postmodern experiences shame as a dominant part of their self understanding, and shame is “our failure to live to an ideal that we have held for ourselves, is an experience of self deficiency. What the postmodern craves, therefore is an ontological coherence– a wholeness of being that always seems to be out of reach.”

I have been pondering this for some time now. Do you think that is an accurate evaluation of the pomo condition? Is that the typical postmoderns self understanding?
