 What was Lakatos’s response to this dilemma? It is sometimes suggested, not least by Feyerabend himself, that Lakatos did have, or would have had, an answer but that he did not live to write it up. Their correspondence suggests otherwise. Although the locus classicus of Feyerabend’s argument is chapter 16 of Against Method (1975b) he had already developed his dilemma in “Consolations for the Specialist” (1968) and Lakatos had access to successive versions of the argument in the successive drafts that Feyerebend sent him in the last is six years of his life. Yet there is no trace of a counterargument in Lakatos’s surviving letters to Feyerabend. Instead there are a series of fearsome threats.
