Overall, pleasure just has a terrible reputation, for some reason even non religious friends of mine do not desire to admit pleasure is the highest good.
Perhaps this is because when first impulses are followed instead of the wise consideration of choices and avoidances, an individual may end up with a unpleasant result.
Another question: does desire cause one to be "blinded" or unable to clearly observe reality?
Desire is a motivator (both a feeling and a thought) to take a specific action when we believe that what we do will result in pleasure and enjoyment. Pleasure is just an end result when life-serving human needs are met. Yet desire and pleasure get all tangled up. (There is still more introspection which I myself need to do on this).
