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.

Sextus Empiricus: Outlines of Pyrrhonism

The Outlines of Pyrrhonism (Πυῤῥώνειοι ὑποτυπώσεις, Pyrrhōneioi hypotypōseis) is a work by Sextus Empiricus, written sometime in the second or third century CE. it is the main source for the ideas of the sceptical movement which traced its roots to Pyrrho of Elis, a philosopher who lived hundreds of years earlier in the 3rd Century BC. 

The Pyrrhonists were opposed on the one hand to dogmatic philosophers such as the stoics, who believed they could attain certain knowledge, and on the other to the rival form of scepticism associated with the Academics, or followers of Plato.

Rediscovered during the renaissance, the work had a profound influence on modern thinkers such as Montaigne, Descartes and David Hume.

Cicero: Academica - discusses the form of scepticism, distinct from Pyrrhonism, associated with the Platonic Academy at some periods.


Cicero: Academica

The Academica is Cicero's main philosophical work on the theory of knowledge. The first edition, the Academica Priora, consisted of two books, the dialogues Catulus and Lucullus, of which only the latter is extant. Lucullus defends the stoic position on the possibility of certain knowledge, which Cicero argues takes the view of the academic sceptics that it is necessary to accept what is merely probable.

Part of a revised version, the Academica Posteriora,  in which Varro replaced Lucullus as the main interlocutor, also survives.

Aristotle: Posterior Analytics

In the Posterior Analytics, Aristotle moves on from the study of formal rules of reasoning  in the Prior Analytics to consider the substantive application of logic to produce scientific knowledge, something which he believes is the product of correct reasoning from true premises. This involves him in addressing Plato's Meno's Paradox, seeking to show how knowledge is possible from a position of former ignorance.

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.

Plato: Meno

The Meno is among the most famous of Plato's shorter dialogues, thanks to Socrates exposition of the theory of innate knowledge or anamnesis, by using close questioning to elicit from a slave geometrical knowledge that he did not know he had. The problem to which this theory is a response, of how we can come to know anything of which we are originally ignorant, has become known as Meno's paradox.
