“Psychology has most often been defined as science of consciousness, but this definition does not go far enough. For consciousness does not occur impersonally. Consciousness, on the contrary, always is a somebody-being-conscious. There is never perception without a somebody who perceives, and there never is thinking unless some one thinks. And this somebody is not an isolated self but a self which is affected from without and which expresses itself in its behavior. In view of these facts psychology is more exactly defined as science of the self in relation to, or conscious of, its environment.”
