Correct.....he was not"criticizing"...he was describing the changing character of "models"...eg. Newtonian physics (fixed frame) vs Relativistic physics (Observer dependent frame). What matters is not "factual truth" but "successful prediction" of observations. That is all that "properties" amount to...prediction of observation. Such predictions are often suggested by the mathematical coherence of models which resist "logical" explanation (like Feynman's positrons as "electrons travelling backwards in time"). Observation is thus guided
and "data" are never independent of observers.Since mathematics is a relatively culture neutral meta language, paradigmatic shifts tend to globally progressive rather than culturally differentiated. A potentially interesting paradigmatic schism is happening right now with the dispute about whether the "speed of light" is an upper limit. There are those who argue the new data "must be wrong" or the current framework of models will fall apart.
All this has been said in this forum countless times. We operate successfully in our mundane lives as though
there were a "reality" independent of "us", because most of the time our physiological and psychological differences are insufficient to cause substantial disagreements about observation. But what we forget is that "observation" is a social
event even if it involves self talking to self. As I sit here in this room there are potentially an infinite number of trivial observations I might
make...from the colour of the carpet to the speck of dirt on the mirror....but the "reality" of those "things" is a function of my socialization through language in common with others with visual systems like mine. And as Heidegger pointed out, we do not actually
evoke either "things" or "self" most of the time
. Such "facticity events" are triggered when the flow of undifferentiated interaction is interrupted and we contemplate
our next move. In other words, we never
actually wander around saying "grass is green" or "rocks are hard" as diembodied "facts"....we would be locked up if we did !
