Re: Sanna - Looking for feedback!
- Dear Robert M
How are you?
Your post on the participation of sa~n~naa (memory) in the processes
of perceptual consciousness (pa~ncadvaaraviithi, five-door cognitive
road) and in the processes of conceptual consciousness
(manodvaaraviithi, mind-door cognitive road) is fantastic.
Please kindly note that I use the term "concept" as meaning any
object or stimulus of mind-door cognitive road. That is to say,
whenever I use the term "concept", concept refers to both realities
(paramattha dhammaa) and conventions or designations (pa~n~natti
Thus, we can simplify types of viithi by grouping them into the
perceptual consciousnesses (for five-door cognitive road) and the
conceptual consciousnesses (for mind-door cognitive road).
Perceptual consciousness would process percepts while conceptual
consciousness would process concepts.
Your presentation of dot matrix or digital processing of visual data
is very much in line with how ancient Theravada Buddhist commentators
understood and explained the issue.
As you might have already learnt the subject from the works of
authors like Shwe Zan Aung, digital processing of perceptual data
involves vitthi types beyond initial five-door cognitive roads. I
call these viithi types the follow-up mind-door cognitive roads
(Tadanuvattika manodvaaravitthi) or follow-up conceptual
As you already know, since memory (sa~n~naa) participates in every
consciousness, every step of the perceptual consciousness processing
and the follow-up conceptual consciousnesses would utilize memory.
Thus, the whole process of coming to know a percept as we know it (a
face, for example) exploits both perceptual consciousnesses and
conceptual consciousnesses as many as necessary and utilizes
instances of memory chains in all of them.
The implication of this abhidhamma psychology is, as you might guess
it, that the world of percepts (sights, sounds, smells, tastes, and
touches) are the end results of mental constructions.
