“I’m convinced that when an atmosphere is created which puts an extreme emphasis on experience over understanding, that atmosphere will inevitably create and encourage infantile selfishness.”

This is a relatively old essay but it gives a good critique of the Human Potential Movement and the impact that this and related ideologies have had on modern western society.
The focus on personal experience without any rational analysis or thought has helped to deliver us a society where every idea no matter how stupid is seen as equally valid.
Really a quite preposterous thing when one stops to think about it!
