Our culture depends in many ways on the creation of standards and conventions that we all must adhere to. These conventions are often expressed in terms of opposites— good and evil, beautiful and ugly, painful and pleasurable, rational and irrational, intellectual and sensual. Believing in these opposites gives our world a sense of cohesion and comfort. To imagine that something can be intellectual and sensual, pleasurable and painful, real and unreal, good and bad, masculine and feminine is too chaotic and disturbing for us. Life, however, is more fluid and complex; our desires and experiences do not fit neatly into these tidy categories.
