The following terms are ones constantly used in psychology, and are
briefly defined that there may be no haziness in their application.

_Sensation_ is the uninterpreted response of the mind to stimuli brought
by sense organs.

{ hot.
Examples: Feeling of { cold.
{ pain.

Sensation may arouse instinct and cause reflex action, or start a
feeling state, or a train of thought.

_Perception_ is the conscious recognition of the cause of a given
sensation.

{ fluid--water.
Example: { cold--snow.
{ pain--cut.

_Percept_ is a word often used to denote the mind's immediate image of
the thing perceived.

Percepts are of two kinds: object and quality.

Example: { object, as water.
{ quality, as fluid.

_Memory_ is the mind's faculty of retaining, recognizing, and
reproducing sensations, percepts, and concepts.

_Organic memory_ is the mind's reproduction of past bodily sensations.

Example: I recall the physical sensations of a chill, and live it over
in my mind, so that I can accurately describe how a chill feels to me,
though I can but surmise how one feels to you.

_Inorganic memory_ is the mind's reproduction of its own reactions in
the past.

Example: Myself having a chill, how I acted; what I thought and my
emotions during that chill.

_Ideation_ is the mind's grouping of percepts by the aid of memory, to
form concepts.

Example: I perceive color, form, mouth, eyes, nose, chin, etc. These
percepts I combine as a result of past experience (memory) to form my
concept, _face_; and the process of combining is ideation.

_Concepts_ are mental representations of things or qualities,
_i. e._, of object or quality percepts.

We might say that the percept is the mind's immediate image of a thing
or quality, and the concept is the result of the storing up and grouping
and recombining of percepts. Thus a lasting mental picture is secured;
and my idea of horse, for instance, is so clear and definite a thing in
my m
