Prior Analytics

The Prior Analytics (Ancient Greek: Ἀναλυτικὰ Πρότερα; Latin: Analytica Priora) is a work by Aristotle on reasoning, known as syllogistic, composed around 350 BCE.

"[4] In the third century AD, Alexander of Aphrodisias's commentary on the Prior Analytics is the oldest extant and one of the best of the ancient tradition and is available in the English language.

[7] Modern work on Aristotle's logic builds on the tradition started in 1951 with the establishment by Jan Łukasiewicz of a revolutionary paradigm.

His approach was replaced in the early 1970s in a series of papers by John Corcoran and Timothy Smiley[8]—which inform modern translations of Prior Analytics by Robin Smith in 1989 and Gisela Striker in 2009.

Scholars Jan Lukasiewicz, Józef Maria Bocheński and Günther Patzig have sided with the Protasis-Apodosis dichotomy while John Corcoran prefers to consider a syllogism as simply a deduction.
