  Knut Sondre Sæbø addressed criticism #3607.

It sounds like you have a different conception of knowledge and rationality from Popper’s/Deutsch’s.

There’s a unity of knowledge. Knowledge isn’t fragmented the way you suggest. Rationality means finding common preferences among ideas, ie making different types of ideas jibe. Why should that not be possible for the types of knowledge you mention?

Even if knowledge is unified at some fundamental level, we might not be able to live by means of this unified knowledge alone (because of how we function or pure complexity). Living life might require operating through other «kinds» of knowledge which are pre- cognitive. You cannot ride a bike or maintain a relationship by thinking through quantum mechanical or propositional theories to word.
