 Lakatos’s strategy was to accept the facts but reverse the value-judgment by developing the twin concepts of a degenerating research programme and a degenerating problem-shift and applying them to Carnap’s successive endeavours. But Carnap’s programme was philosophico-mathematical rather than scientific. So what was wrong with it could not be that it failed to predict novel facts or that its predictions were mostly falsified. For it was not in the business of predicting empirical observations whether novel or otherwise. (Indeed Lakatos’s concept of a degenerating philosophical programme seems to have preceded his concept of a degenerating scientific programme.) So what was wrong with Carnap’s enterprise? In an effort to solve his original problem, Carnap had to solve a series of sub-problems. Some were solved, others were not, generating sub-sub-problems of their own. Some of these were solved, others were not, generating sub-sub-sub-problems and sub-sub-sub-sub-problems etc. Since some of these sub-problems (or sub-sub-problems) were solved, the programme appeared to its proponents be busy and progressive. But it was drifting further and further away from achieving its original objectives.
