Your posts are way too long and convoluted. If you have something to say, get to the point without an entire chapter to explain it. There are too many posts for me to respond to than just yours. I'm sorry that I've lost patience. Just shorten your responses, and I'll do my best to respond.
Yes. Thinking is difficult and takes time. Especially thinking in terms of multiple facets, multiple variables, multiple perspectives. All that I request is that you finally exhibit both semantics and logic capabilities when you address any of the following points.
1) It was
demonstrably established that afference is certainly necessary for the sort of conditioning at issue to occur. This was accomplished with the discussion of the conditioned blind person.
2) You admit that both light and vision are afferent when you admit that light "
is 100% necessary for the biological vision process to occur". See below at 4) for further explanation of how light is necessary.
3) The fact that vision is a process or is the result of a process means that vision is a matter of afference. The fact that light is transformed during the vision process means that light is afferent. See below at 5) and 7) for further explanation regarding how the fact that vision is process-related means that vision is necessarily a matter of afference.
4) You admit that vision is a matter of light afference when you admit that light participates in the vision process (as you say: "
Light DOES participate"). That participation is necessary to justify regarding light as necessary for vision to occur.
5) Given that all processes occur over time, then light is afferent (light energy at the eye travels inwardly) as it is transformed during its inclusion in, its contribution to, its participation in the process which results in vision.
6) Since light is afferent as per your own admission of there being an over time vision-resulting process for which light is necessary, and since you admit that light as afferent (and, therefore, vision as afferent) is incompatible with the notion of vision as efferent, you necessarily deny that vision is efferent because you admit that vision is afferent.
7) You admit that light exhibits afference in that it contributes to the process which produces vision - a process which necessarily takes time.
8) Since you recognize that the vision process takes time, you cannot escape concluding that it is not even possible for vision to occur instantaneously (or what you describe as occurring in "real time").
9) Afference is necessary for conditioning to occur. You admit that light is afferent. Light resulting in vision can be included in a conditioning process because light and vision are afferent. The Lessans efferent vision notion has no logical or empirical or otherwise observational basis and is not needed in order to understand vision and conditioning.
