desire

my friend writes:
Desire, being a sort of crisis state, is more exiting to the ego. We know that both the ego and capitalism thrive in an environment of constant crisis. As capitalism and the individual ego became more important, so desire became more important than pleasure. This makes me think of 'the pursuit of happiness'. Individuals supposedly have the right to PURSUE happiness, but actually experiencing happiness is depicted as perverse or deviant because it is seen as static.
i write:
with the rise of what foucault calls 'pastoral power,' desire required constant interrogation for the devil could always be behind your thoughts. the sexual was one of THE hot spots for 'revealing' the truth of the self. today (and this is history of sexuality vol. 1) we still give sex that privileged spot, only now, we think that liberation means attacking the 'repression' that was brought upon our sexuality.

am i correctly using the term 'pastoral power'?
