History and Schools of Metaphysics

Scholasticism and the Middle Ages

Between about 1100 and 1500, philosophy as a discipline took place as part of the Catholic church’s teaching system, known as scholasticism. Scholastic philosophy took place within an established framework blending Christian theology with Aristotelian teachings. Although fundamental orthodoxies could not be challenged, there were nonetheless deep metaphysical disagreements, particularly over the problem of universals, which engaged Duns Scotus and Pierre Abelard. William of Ockham is remembered for his principle of ontological parsimony.

Rationalism and Continental Rationalism

In the early modern period (17th and 18th centuries), the system-building scope of philosophy is often linked to the rationalist method of philosophy, that is the technique of deducing the nature of the world by pure reason. The scholastic concepts of substance and accident were employed.

• Leibniz proposed in his Monadology a plurality of non-interacting substances.
• Descartes is famous for his Dualism of material and mental substances.
• Spinoza believed reality was a single substance of God-or-nature.
