All of the other mental modalities have their source in perception. Memory comes directly from perception, knowledge is the subcless of former memories that have been narratively compressed or abstractly represented, imagination is comprised of perceptions and memories deconstructed and components of them recombined, and cognition is the deconstruction and recombination of components of perception and knowledge.
Memory is restricted to the reproduction to some degree of a segment of past perception, complete with a spatiotemporal perspective; thus memory is diachronic and positional. On the other hand, knowledge of an informational datum would not entail that we be capable of reproducing the experience of learning it; thus knowledge may be considered synchronic and apositional. Imagination and cognition extrapolate possibilities from the actualities grasped in perception and retained in (for imagination) memory and (for cognition) knowledge. However, imagination is restricted to a generation of possible perceptions from particular spatiotemporal perspectives and is diachronic and positional; cognition is synchronic and apositional. Although they are all to some degree autonomous with respect to perception (knowledge and cognition more so than memory and imagination, due to the fact that the former two have dispensed with spatiotemporal context), they are all directly or ind!
irectly grounded in perception, and recurse to inform it. Forgetting needs to be mentioned also. If we consider memory to be an imprinted representation of presented experience, a perceptual text, if you will, and subsequent experience to be continually inscribing upon the same neural parchment, the minor details and routine experiences would become obliterated first; thus broad outlines and the unusual would be remembered longer. Finally, the experiential, that is, spatiotemporal and object-perceptual context in which the information was received would be destroyed, and thbat which remains would no longer be memory, but knowledge. Cognition deconstructs and recombines these nerratized and abstracted remainders, as imagination deconstructs and recombines memory images (of all percpetual media, not just visual) and perceptions.
