Aquinas: Summa Theologica

St Thomas Aquinas by Carlo Crivelli (1476). Wikimedia CommonsThe Summa Theologica or Summa Theologiae by Saint Thomas Aquinas (1225-1274) is one of the best known philosophical works of the Middle Ages. Intended as a comprehensive guide to theology for beginning students, the first part of the work deals with God, nature and man, the second part with law and morality, while the third, unfinished part deals with Christ and the sacraments, seen as the route of humanity's return to God, thus giving the whole a cyclical structure.

Cicero: On Fate

On Fate (Latin: De Fato) is a partly extant work by Cicero, written in 44 BC, in which he discusses fate and freedom of the will with his friend Aulus Hirtius. Although, ostensibly a dialogue, the extent portions contain long passages of exposition by Cicero. The work appears to be closely connected to On the Nature of the Gods and On Divination.

Porphyry: The Isagoge

The Isagoge or Introduction by Porphyry is a commentary on Aristotle's Categories, which itself became a key logical text of the Middle Ages, being translated into Arabic via Syriac, and into Latin by Boethius. Along with the Categories and On Interpretation, it formed part of the Ars Vetus or Old Logic, the works available in the Medieval Latin West prior to the translation of Aristotle's other logical works.

The medieval concept of the Porphyrian Tree was inspired by Porphyry's presentation of Aristotle's system of  classification. Porphyry bracketed the issue of whether Aristotelian genera and species were merely concepts used to describe particular things or had independent reality, but his formulation of the question was, via Boethius, influential for the medieval debate about universals.

Aristotle: On Generation and Corruption

On Generation and Corruption , sometimes known as On Coming to Be and Passing Away (Greek: Περὶ γενέσεως καὶ φθορᾶς, Latin: De Generatione et Corruptione), is a treatise of Aristotle, closely related to his Physics, which asks whether the generation of things always comes about through the alteration of existing things. It examines the views of a number of pre-Socratic philosophers on this question.

Aristotle: The Metaphysics

The Metaphysics (Greek: τὰμετὰτὰφυσικά; Latin: Metaphysica) is a key philosophical work of Aristotle. The book's name originally came from its position after the Physics in Aristotle's collected writings. However, it's title subsequently provided the name for the branch of philosophy with which it was concerned, addressing the fundamental nature of being.

Plotinus: The Enneads

The Enneads of Plotinus represent the surviving teachings of the most influential philosopher of Late Antiquity. Plotinus' synthesis of earlier thought, adapting Aristotle to the study of Plato, has been seen as inaugurating a neoplatonic tradition that was formative for Jewish, Christian and Islamic philosophy as well as later pagan thought. 

The Six Enneads are treatises compiled from Plotinus' lectures by his pupil Porphyry, also the author of a biography that makes Plotinus one of the best-known of ancient philosophers.

Plato: The Sophist

The Sophist is one of a small number of late Platonic dialogues in which Socrates cedes the lead role, in this case to the Eleatic Stranger, a follower of the presocratic philosophers Parmenides and Zeno. The discussion is presented as taking place a few days after the Theaetetus, and picks up some of the earlier dialogues themes in the course of discussing how the sophist differs from the true philosopher and the statesman.

Plato: The Republic

 

The Republic is Plato's best-known work. An extended reflection on the nature of justice, which retains much of the style of the early dialogues in the opening conversation in Athens, pitting Socrates against the cynical sophist Thrasymachus. From there the dialogue opens out into an extended discussion of the politics of the ideal city, which is closely bound up with ethical considerations, before taking in metaphysical and theological themes with Plato's most striking metaphor, the parable of the cave, and a meditation on the the fate of the individual soul in the myth of Er.
