Social psychology has for the most part been written in terms of behavior. It is the purpose of this paper to point out that the profound and striking differences which exist between the social psychology of man and that of the lower animals as a class are due to the presence in man of a factor which can be most concisely described in introspective terms. This factor I have called, for brevity of reference, ejective consciousness: it is the awareness of thoughts and feelings as belonging to other minds than our own, the awareness of the contents of other people's minds.
