 To the many that knew and loved the later Lakatos, some of these facts are difficult to digest. But how relevant are they to assessing his philosophy, which was largely the product of his British years? This is an important question as Lakatos was wont to draw a Popperian distinction between World 3—the world of theories, propositions and arguments—and World 2—the psychological world of beliefs, decisions and desires. And he was sometimes inclined to suggest that in assessing a philosopher’s work we should confine ourselves to World 3 considerations, leaving the subjectivities of World 2 to one side (F&amp;AM: 140).
