For example, dodging and weaving through a crowd is not social behavior, usually. Others are considered as mere physical objects, as human barriers with certain reflexes. Neither is keeping in step in a parade social behavior. Other marchers are physical objects with which to coordinate one's movements. Neither is a surgical operation social behavior. The patient is only a biophysical object with certain associated potentialities and dispositions. However, let the actor become involved with another's self, as a person pushing through a crowd recognizing a friend, a marcher believing another is trying to get him out of step, or a surgeon operating on his son, and the whole meaning of the situation changes.
With this understanding of social, let me now define social acts, actions, and practices. A social act is any intention, aim, plan, purpose, and so on which encompasses another self. These may be affecting another's emotions, intentions, or beliefs; or anticipating another's acts, actions, or practices.1 Examples of social acts would be courtship, helping another run for a political office, teaching, buying a gift, or trying to embarrass an enemy.
