A sociological and psychological examination of how individual consciousness and social life interpenetrate, rejecting any sharp opposition between person and society. It traces how suggestion, choice, and sociability shape thought and feeling, using observations of children and everyday interactions to show imaginary conversation and personal ideas as social phenomena. Sympathy is analyzed as communal feeling that structures personality and moral orientation. Finally, the study treats the social self, exploring senses of I, phases of self-feeling, and the balance between individual uniqueness and communal influence.
