[Jim Dundon 08.27.06 1540eds]Jim Dundon (08.25.2006.1200edst> Are you not asking here whether or not a perception should be
considered less valid if we cannot measure something in scientific
terms, scientific here meaning narrowed parameters and purified
components?
From Rick Marken (2006.08.25.1220)
No. I was asking whether some perceptions correspond to external
reality (as we know it via our models, which, of course, is the only
way we can know external reality) better than others.I was asking about objectivity in the sense of the correspondence of perception to external reality. I myself don't think any perception is more objective in this sense than any other.Jim D:So what is this measure of uniform correspondence with reality?Have you discovered a new constant?This would also mean that no model is ever changed because that would require rating the old model, a perception of external reality, as having less correspondence than the new model, that would violate your axiom.Accordingly all perceptions must be rated as having the same measure of correspondence with reality as any other at all times and so also itcan never be said to have been improved on because it would mean that it wouldnow have a higher rating of correspondence to reality than the others. We would never have a sense of change in the perception of our hold on reality.If we experienced a change in the correspondence/objectivity to external realityrating of one of our perceptions we would assume all other perceptions to be rerated accordingly.Your question assumes an external reality, but If the only way we can know external reality is by modeling it, it follows that we knew of no external reality before we modeled so why did we start modeling?PCT says behavior is purposefull so in keeping with that I will say that external reality was assumed and created in order that some modelers could model.As you said above the only way we can know [experience] external reality is by our models.I will paraphrase it ever so slightly: We experience the notion of an external reality simultaneously with our modeling and since correspondence is always uniform[never changes] we are simultaneously always right!!! bestJim D
