In critical theory, philosophy, sociology, and psychoanalysis, the gaze, in the figurative sense, is an individual's awareness and perception of other individuals, other groups, or oneself. The concept and the social applications of the gaze have been defined and explained by existentialist and phenomenologist philosophers. Jean-Paul Sartre described the gaze in Being and Nothingness (1943). Michel Foucault, in Discipline and Punish: The Birth of the Prison (1975), developed the concept of the gaze to illustrate the dynamics of socio-political power relations and the social dynamics of society's mechanisms of discipline. Jacques Derrida, in The Animal That Therefore I Am (1997), elaborated upon the inter-species relations that exist among human beings and other animals, which are established by way of the gaze.
