Lekton (Greek, ‘what can be said’), a Stoic term sometimes translated as ‘the meaning of an utterance’. Lekta differ from utterances in being what utterances signify: they are said to be what the Greek grasps and the non-Greek speaker does not when Greek is spoken. Moreover, lekta are incorporeal, which for the Stoics means they do not, strictly speaking, exist, but only ‘subsist,’ and so cannot act or be acted upon. They constitute the content of our mental states: they are what we assent to and endeavor toward and they ‘correspond’ to the presentations given to rational animals. The Stoics acknowledged lekta for predicates as well as for sentences (including questions, oaths, and imperatives); axiomata or propositions are lekta that can be assented to and may be true or false (although being essentially tensed, their truth-values may change). The Stoics’ theory of reference suggests that they also acknowledged singular propositions, which ‘perish’ when the referent ceases to exist.
