I was under the impression that Si functions as a composition of sensory memories, rather than Se, which induces a reaction to immediate sensory stimulation.
Si, being introverted, continually relates sensory information with "Psychic archetypes". These archetypes are formed from experiencing different objects over time and grouping them based on similarity of their sensible qualities.
Thus Si confers a higher value on the archetypes (The
Subjects), than on the object itself.
Similarity of object to past objects experienced

What the object suggests for its immediate context
(Btw, I would like to know how your theory differs from my own, so that I may better understand yours)
