The ancient Greek logos, that we may translate by “statement”, can refer to any signifying linguistic whole that can be analysed into constitutive parts which are themselves signifying words, in fact, that the tradition will define as “parts of logos”. Plato declares a sequence such as “the man learns” to be “primary and minimal” form of logos, described as the intertwining of a noun (onoma) and a verb (rhèma). This complex object, subject to a syntax, possesses the sui generis attribute of saying something, true or false, about the world: Aristotle will call it logos apophantikos “declarative statement” –and it is through leaning on this base that the Greek logical-grammatical tradition will shed light on the diversity of these statements which are other than simple and declarative. The Stoics have made here a decisive contribution whose fecundity one can glimpse in the surviving works of Apollonius Dyscolus.
