Is Knowledge Amenable to a Scientific Study?

Popper: People who want to make progress can largely ignore the gainsayers. He says counterfactuals provide a way out of this trouble. If we define knowledge as information with the ability to last, has the ability to create new knowledge, we are able to free them of any subjective tinge and make them objective. This is still very far from providing a theory of those phenomena, but it provides a scientific handle on knowledge by grounding it in the laws of physics.
