“It is hard to overstate the biological significance of obsessions, compulsions and the psychological mechanisms that produce them. On the one hand, compulsions bear striking similarities to various repetitive, ritualized behaviors observed in other animals --including self-grooming, food inspection and washing, and checking for predators. On the other hand, cultural rituals --which also share several features with OCD symptoms-- perform a range of important functions in human societies, from group coordination in social and religious ceremonies to the transmission of knowledge between generations.” — Marco del Giudice
