Medieval philosophy

For instance, such thinkers as Augustine of Hippo and Thomas of Aquinas made monumental breakthroughs in the philosophy of temporality and metaphysics, respectively.

The principles that underlie all the medieval philosophers' work are: One of the most heavily debated things of the period was that of faith versus reason.

The first significant renewal of learning in the West came when Charlemagne, advised by Candidus, Peter of Pisa and Alcuin of York, attracted the scholars of England and Ireland, and by imperial decree in 787 AD established schools in every abbey in his empire.

Johannes Scotus Eriugena (c. 815 – 877), successor of Alcuin of York as head of the Palace School, was an Irish theologian and Neoplatonic philosopher.

By the mid-ninth century, its library was one of the most comprehensive ever assembled in the West, and scholars such as Lupus of Ferrières (d. 862) traveled there to consult its texts.

[9]: 1 Remigius of Auxerre, at the beginning of the tenth century, produced glosses or commentaries on the classical texts of Donatus, Priscian, Boethius, and Martianus Capella.

The Carolingian period was followed by a small dark age that was followed by a lasting revival of learning in the eleventh century, which owed much to the rediscovery of Greek thought from Arabic translations and Muslim contributions such as Avicenna's On the soul.

It is generally agreed to begin with Saint Anselm of Canterbury (1033–1109) an Italian philosopher, theologian, and church official who is famous as the originator of the ontological argument for the existence of God.

[12] William of Moerbeke's translations and editions of Greek philosophical texts in the middle half of the thirteenth century helped in forming a clearer picture of Greek philosophy, and in particular of Aristotle, than was given by the Arabic versions they had previously relied on, which had distorted or obscured the relation between Platonic and Aristotelian systems of philosophy.

The universities developed in the large cities of Europe during this period, and rival clerical orders within the Church began to battle for political and intellectual control over these centers of educational life.

Their leader in the middle of the century was Bonaventure, a traditionalist who defended the theology of Augustine and the philosophy of Plato, incorporating only a little of Aristotle in with the more neoplatonist elements.

By contrast, the Dominican order, founded by St Dominic in 1215 placed more emphasis on the use of reason and made extensive use of the new Aristotelian sources derived from the East, and Moorish Spain.

The great representatives of Dominican thinking in this period were Albertus Magnus and (especially) Thomas Aquinas, whose artful synthesis of Greek rationalism and Christian doctrine eventually came to define Catholic philosophy.

However, the discipline now called Philosophy of religion was, it is presumed, a unique development of the Medieval era, and many of the problems that define the subject first took shape in the Middle Ages, in forms that are still recognisable today.

Subjects discussed in this period include: After the 'rediscovery' of Aristotle's Metaphysics in the mid-twelfth century, many scholastics wrote commentaries on this work (in particular Aquinas and Scotus).

However, from the fourteenth century onward, the increasing use of mathematical reasoning in natural philosophy prepared the way for the rise of science in the early modern period.

From the time of Abelard until the middle of the fourteenth century, scholastic writers refined and developed Aristotelian logic to a remarkable degree.

In the earlier period, writers such as Peter Abelard wrote commentaries on the works of the Old logic (Aristotle's Categories, On interpretation, and the Isagoge of Porphyry).

Medieval philosophy of mind is based on Aristotle's De Anima, another work discovered in the Latin West in the twelfth century.

Contributions: In his narrative pieces, al-Farabi discussed ethical and philosophical theories with reference to politics, leadership, morals, faith, and civics.

Notable works of his include The Attainment of Happiness, in which al-Farabi reasons that conceptions of political science and religion must be built on a foundational understanding of the universe.

He advocates that one must first construct notions in relation to universal matters to form just opinions in regard to political philosophy and religion.

Much of his writing is deliberated on his perceived conceptions of the juxtaposition and interaction of the aforementioned topics such as his claim that both political and religious figures rest in the same classification as adjacent to a fundamental comprehension of the universe.
