It is often claimed in this context that a person defines himself, which is often perceived as stating that we can "wish" to be something — anything, a bird, for instance — and then be it. According to most existentialist philosophers, however, this would be an inauthentic existence. What is meant by the statement is that a person is (1) defined only insofar as he or she acts and (2) that he or she is responsible for his or her actions. For example, someone who acts cruelly towards other people is, by that act, defined as a cruel person. Furthermore, by this action of cruelty such persons are themselves responsible for their new identity (a cruel person).
