Prose
The word "prose" first appears in English in the 14th century. It is derived from the Old French "prose", which in turn originates in the Latin expression "prosa oratio" (literally, straightforward or direct speech).
Peritrope
The name comes from the ancient Greek for "turning around". Sextus Empiricus is thought to have given the name in a comment on the passage. The name has been in continuous use ever since, as Socrates' argument provides the foundation for classical propositional logic and hence much of traditional western philosophy (or analytic philosophy). For instance, Sextus noted that Protagoras' famous doctrine that man is the measure of all things is self-refuting because "one of the things that appears (is judged) to be the case is that not every appearance is true". This assumption was later refuted due to a mistake on the part of Sextus' interpretation that the Protagorean measure doctrine boiled down to a subjectivist thesis that whatever appearance whatsoever is true.
