Is knowledge also a belief?

I think it is both: an understanding problem and an ideological problem. And this seeming unsurmountability would be solvable, if it was not a mix of both: an understanding problem and an ideological problem.

Probably you remember the follwing conversation:

Again: Ignore him?

During my study at the university I have met many types of students who were back then exactly like he is now. It is their ideological conceitedness that makes them so cocksure and ignorant, so that they do not only appear like stupid people but really are stupid people. You do not really have to care whether their incapacity is based on genetic defects or on ideological defects, because the effect is the same old stupidity as ever.
