Nominalism, Mysticism, and the End of Scholasticism

The Debate on Universals

One of the most famous debates of medieval philosophy is the debate about universals: do general concepts (such as “humanity”, “beauty”, “justice”) exist in reality, or only as words? Realists (Anselm, Thomas Aquinas) claimed: yes, general concepts exist really. Nominalists (Roscelin, William of Ockham) answered: only concrete things are real; general concepts are just words (nomina), convenient tools for thinking.

This debate is not just a verbal game. It has theological consequences: if “humanity” is real, it is easier to speak about the natures of Christ and the unity of the Trinity. If not, theology becomes significantly more complex. It has political consequences: if “state” or “church” are real as universals, they have independent ontological status. If not, they are simply words, conveniently describing the aggregate of individuals.

William of Ockham (ca. 1287–1347) is the most important nominalist. His “Ockham’s razor”: “Do not multiply entities beyond necessity.” This is a principle of intellectual economy, still used in science: if a phenomenon can be explained by simpler means, there is no need to introduce complexity. Ockham applied it to theology: much that the scholastics considered rationally provable cannot be proven by reason—it is a matter of faith. Reason and faith are separated. This undermines the scholastic synthesis of Thomas Aquinas and opens the road to the science of the Modern Age.

Mysticism: The Path Inward

Alongside scholasticism in the Middle Ages exists another tradition—mysticism: direct, immediate experience of God, bypassing rational proofs. Meister Eckhart (1260–1328), a German Dominican, taught that in the depths of the soul there is a “spark” (Funklein)—a point where a person encounters God directly. It must not be proven, but experienced.

Eckhart used paradoxical language: God is “Nothing”, because He transcends all definitions. “God is that which is none of the things that are.” This is apophatic theology—describing God through negations, by what He is not. Pope John XXII condemned 28 theses of Eckhart as heretical—which only strengthened his popularity.

Mysticism is not irrationalism, but another way of knowing. Julian of Norwich (ca. 1342–1416), an English anchoress, described visions of Christ with astonishing analytical precision. Teresa of Ávila (1515–1582) systematized the stages of prayerful experience. These texts are the first detailed descriptions of altered states of consciousness, anticipating modern psychology.

Renaissance: Return to the Human

Pico della Mirandola (1463–1494), in his “Oration on the Dignity of Man”, formulates Renaissance humanism: God created man last—without a fixed nature. A stone is a stone, a lion is a lion. But a human can become whatever he wants: descend to the level of an animal or rise to the level of an angel. This plasticity is the special dignity of man. The Renaissance person is a master of himself.

Niccolò Machiavelli (1469–1527), though not a philosopher in the strict sense, made a revolution in political thought: he described politics not as it ought to be (Aristotle, Plato), but as it actually is. The ruler must know how to be both a fox (cunning) and a lion (strength). Virtue (virtu) for him is not morality, but political skill, the ability to use fortune for one’s own purposes.

Legacy

Three lines lead from the Middle Ages to the Modern Age. The Ockham line (separation of faith and reason) leads to the scientific revolution. The mystical line leads to Luther’s Reformation and Protestantism with its focus on personal relationship to God. Renaissance humanism leads to the philosophy of the subject—to Descartes.

The Middle Ages are not the “Dark Ages”—they are a millennium of intense intellectual labor, creating institutions (universities), methods (scholasticism), and problems (faith and reason, freedom of will, nature of evil) which Western thought continues to develop to this day.

Question for reflection: Ockham’s razor advises not to multiply explanations beyond necessity. In what complex situation from your professional life did you explain events with unnecessary complexity, while a simpler explanation would have been more accurate?
