A Guide to Objective Knowledge (The Popular Popper Book 5)
Objective Knowledge is the subject of the fifth guide in the Popular Popper series. It contains several papers devoted to one of his most exciting and most neglected ideas, the theory of objective or "world 3" knowledge. This did not receive loud cheers from the mainstream philosophy community which had also resisted his view of the conjectural nature of knowledge.
Popper turned away from the justification of subjective beliefs and extended conceptual analysis to get serious about metaphysical research programs and the critical appraisal of the house rules in what Barzun called "the house of intellect". William W. Bartley went so far as to suggest that if Popper was on the right track, many philosophers were wasting much of their professional careers.
Under these circumstances, Popper felt obliged to offer an excuse for indulging in philosophy, at public expense: "My excuse is this. We all have our philosophies, whether or not we are aware of this fact [and] the impact of our philosophies upon our actions and our lives is often devastating. This makes it necessary to try to improve our philosophies by criticism. This is the only apology for the continuing existence of philosophy which I am able to offer."
The guide contains a set of appendices to identify some of the reasons for Popper's low profile in the profession.
