I'm confused. If there's no such thing as the actually true, how are we to understand the claims you make in this comment? Are they not actually true? I take it you don't think they're false. Perhaps they're what you call viable models? But of what? And if you do want to say that they're viable models, you would be saying that its true that they're viable models. But then is the claim that they're viable models itself a viable model? Doesn't this lead to a vicious regress?
