So, "all models are wrong, some models are useful" spun out into a whole philosophy?

In all seriousness, that is becoming one of my guiding principles (along with "divisions into categories are models"), so maybe I should pay more attention to this dude, except that he really is kind of hard to follow sometimes...

I think a better way to put it is that all models are right given a situation / context / set of assumptions. It is important to understand the latter to apply the model.

I would highly recommend reading Chapter 3-5 (Epistemology) of Objectivism by Leonard Piekoff. It's a much more logical and easy to understand take on these same ideas.
