The spiritual, rational, and immortal part in man; that part
of man which enables him to think, and which renders him a subject of
moral government; – sometimes, in distinction from the higher nature,
or spirit, of man, the so-called animal soul, that is, the seat of
life, the sensitive affections and phantasy, exclusive of the voluntary
and rational powers; – sometimes, in distinction from the mind, the
moral and emotional part of man’s nature, the seat of feeling, in
distinction from intellect; – sometimes, the intellect only; the
understanding; the seat of knowledge, as distinguished from feeling. In
a more general sense, “an animating, separable, surviving entity, the
vehicle of individual personal existence.”
