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.
