A dialogue is a discourse consisting of question and answer on some philosophical or political subject, with due regard to the characters of the persons introduced and the choice of diction. The dialectic is the art of discourse by which we either refute or establish some proposition by means of question and answer on the part of the interlocutors.
By Matteo Motterlini
The following dialogue between Lakatos and Feyerabend is obviously nothing more than fiction, but over the years a real dialogue did take place between the two friends. It consisted in a genuine, lengthy, continuous, and outspoken exchange of letters and papers which shows the two men taking stands in the discussion for and against method. My fictitious reconstruction mirrors their own contributions, but paraphrases them for stylistic reasons. . . The rhetorical form of the dialogue is well described in the above fragment by Diogenes Laertius. The reason for adopting it here is given by the two imaginary interlocutors explicitly at the beginning of their discourse.
