“ The man who desires exists his body in a particular mode and thereby places himself on a particular level of existence. In fact everyone will agree that desire is not only longing , a clear and translucent longing which directs itself through our body toward a certain object. Desire is defined as trouble. The notion of “trouble” can help us better to determine the nature of desire. ”
