Chrysippus in the context of "History of logic"

Hermippus of Smyrna (Greek: Ἕρμιππος ὁ Σμυρναῖος) was a Greek grammarian and peripatetic philosopher, surnamed by the ancient writers the Callimachian (Greek: ό Καλλιμάχειος), from which it may be inferred that he was a disciple of Callimachus about the middle of the 3rd century BC, while the fact of his having written about the life of Chrysippus proves that he lived to about the end of the century. His writings seem to have been of very great importance and value. They are repeatedly referred to by the ancient writers, under many titles, of which, however, most, if not all, seem to have been chapters of his great biographical work, which is often quoted under the title of Lives (Bioi). The work contained the biographies of a great many ancient figures, including orators, poets, historians, and philosophers. It contained the earliest known biography of Aristotle, as well as philosophers such as Pythagoras, Empedocles, Heraclitus, Democritus, Zeno, Socrates, Plato, Antisthenes, Diogenes, Stilpo, Epicurus, Theophrastus, Heraclides, Demetrius Phalereus, and Chrysippus. The work has been lost, but many later Lives extensively quote it.

Josephus and Origen cite Hermippus to argue that Pythagoras owed a debt to Judaism.

In linguistics, deixis (/ˈdaɪksɪs, ˈdeɪksɪs/) is the use of words or phrases to refer to a particular time (e.g. then), place (e.g. here), or person (e.g. you) relative to the context of the utterance. Deixis exists in all known natural languages and is closely related to anaphora, with a sometimes unclear distinction between the two. In linguistic anthropology, deixis is seen as the same as, or a subclass of, indexicality.

The term's origin is Ancient Greek: δεῖξις, romanized: deixis, lit. 'display, demonstration, or reference'. To this, Chrysippus (c. 279 – c. 206 BCE) added the specialized meaning point of reference, which is the sense in which the term is used in contemporary linguistics.

Cleanthes (/kliˈænθiːz/; Ancient Greek: Κλεάνθης; c. 330 BC – c. 230 BC), of Assos, was a Greek Stoic philosopher and boxer who was the successor to Zeno of Citium as the second head (scholarch) of the Stoic school in Athens. Originally a boxer, he came to Athens where he took up philosophy, listening to Zeno's lectures. He supported himself by working as a water-carrier at night. After the death of Zeno, c. 262 BC, he became the head of the school, a post he held for the next 32 years. Cleanthes successfully preserved and developed Zeno's doctrines. He originated new ideas in Stoic physics, and developed Stoicism in accordance with the principles of materialism and pantheism. Among the fragments of Cleanthes' writings which have come down to us, the largest is a Hymn to Zeus. His pupil was Chrysippus who became one of the most important Stoic thinkers.
