Philosophy of the Middle Ages and the Renaissance

Philosophy of the Medieval Era

The emergence and establishment of Christianity in Europe ushered in a radical spiritual revolution in the development of European civilization. This can be vividly illustrated through a comparison of the ancient and medieval worldviews based on their fundamental characteristics, as presented in Table 6.

Table 6.

Ancient Worldview	Medieval Worldview
Polytheism (many gods)	Monotheism (one God)
Gods are part of nature or embodiments of natural elements	God is a spiritual essence that exists beyond the world (transcendence)
Primary attributes of gods: power, might	Primary attribute of God: love for humanity
Gods organize the world	God creates the world from nothing
Cosmos, nature - the general conditions of existence for gods and humans	Nature has no inherent essence and cannot exist without divine energy
Humans rely on knowledge in their actions	Humans rely entirely on faith in God
The main life task of humans is to perform heroic deeds	The main life task of humans is the salvation of the soul
In perceiving reality, emphasis is placed on the external; the internal manifests only through the external	In perceiving reality, emphasis is placed on the internal; the external rather hinders proper understanding of the internal
People are compared by ethnic and tribal characteristics	All people are equal before God
Dominance of naturalistic worldview	Dominance of symbolic perception of the world

During the Middle Ages—from the 5th to the 15th centuries—under the dominance of the Christian religion and the omnipotence of the Church, philosophy lost its status as an independent domain of knowledge and found itself in a position described as the "handmaiden of theology." Medieval philosophy regarded not nature, as in antiquity, but the personified spiritual principle—God—as the highest reality, developing primarily as the knowledge of God. Therefore, it is characterized as theocentric. Philosophy was not seen as a means of investigating reality but as a quest for rational pathways to prove the truths of faith, which were already given in the sacred text.

The development of medieval philosophy is generally divided into two main stages: the period of Patristics and Scholasticism. The Patristic period (from Latin "pater" - father) refers to the era of the teachings of the Church Fathers, who shaped Christian dogmas based on the interpretation of Sacred Scripture. In the Scholastic era (from Greek "scholastikos" - school-related, scholarly; in a figurative sense - a doctrine detached from life), the primary task of philosophy became the rational justification and demonstration of church dogmas, providing them with clarity and persuasiveness. The key stages of the development of medieval philosophy and its prominent representatives are reflected in Table 7.

Key Stages and Their Chronological Framework	Prominent Representatives
Patristics 2nd-8th centuries
a) Apologetics 2nd-3rd centuries	Origen, Tertullian, Clement of Alexandria
b) Systematization of Church teaching 4th-5th centuries	In the Latin West - Aurelius Augustine; In the Greek East - Pseudo-Dionysius the Areopagite, Basil the Great, Gregory the Theologian, Gregory of Nyssa
c) Stabilization of dogma late 5th-8th centuries	In the West - Boethius; In the East - Leontius of Byzantium, John of Damascus
Scholasticism 9th-14th centuries
a) Formation 9th-12th centuries	John Scotus Erigena, Anselm of Canterbury, Roscelin, Abelard
b) Mature 12th-13th centuries	Albertus Magnus, Thomas Aquinas, Siger of Brabant
c) Late 13th-14th centuries	John Duns Scotus, William of Ockham

In contrast to Greek philosophy, which was intertwined with pagan polytheism, medieval philosophical thought was based on Christian monotheism, founded on two important principles: the idea of divine creation (creationism) and the idea of divine revelation. The notion of creation became the foundation of medieval ontology: God, as the absolute being, created nature and humanity from nothing, solely through His will.

The idea of revelation formed the basis of epistemology: God reveals Himself to humanity through sacred texts, the interpretation of which was seen as a means of divine knowledge. Truth need not be sought; it already exists in the text. A significant theoretical and epistemological problem emerged regarding the nature of universals—general concepts. This issue gave rise to two theories: realism and nominalism. Realists maintained that general concepts exist in reality prior to the appearance of specific things and are the causes that bring them into existence. Nominalists argued that only individual things, as given in sensations, exist in reality, while general concepts are merely names for things.

One of the central problems of epistemology was also the relationship between faith and reason in knowledge. During the early Middle Ages, the prevailing view was one of incompatibility between faith and rational proof, as expressed by Tertullian in the principle: "I believe because it is absurd." Over time, influenced by the growth of scientific knowledge, the perspective shifted towards the possibility of harmonizing faith and reason: "I believe in order to understand" (Augustine, Anselm) and also "I understand in order to believe" (Abelard). Expanding on this notion, Thomas Aquinas developed a doctrine of the harmony of faith and reason as modes of knowledge, the main tenets of which are presented in Table 8. He also formulated five rational proofs for the existence of God.

Table 8.

Conditions for the Symphony of Reason and Faith According to Thomas Aquinas

There exist truths that can be grasped by natural reason—the realm of science and philosophy

There exist truths that exceed human capabilities: they are given only in divine revelation and concern matters of creation, salvation, and the immortality of the soul

There exist truths that can be understood through both reason and faith—here philosophy and theology must cooperate, but philosophy must align itself with theology

Theology is the ideological component of religion tasked with reconciling all major religious dogmas. The interaction between philosophy, theology, and religion in the Middle Ages can be illustrated in Table 9.

Table 9.

Philosophy	Theology	Religion
Developed the intellectual tools for theology	Contributed to:	Required adherence to its dogmas on faith
- The philosophical interpretation of religion	- The sacralization of philosophy
- The subordination of reason to faith	Taught Christians to speak in "philosophical language"	Initiated new philosophical issues
Rationalized religious dogmas		Verified the truths of philosophy
Pursued absolute truth through human reason		Prescribed how one should act and live

Particular attention was given to the inner life of individuals, the inner person, their self-awareness directed towards God through confession. During this time, self-consciousness of the individual developed, culminating in a heightened sense of the self. The meaning of earthly life lies in the salvation of the soul for eternal otherworldly life, in unity with God. The idea of God as a moral absolute establishes strict boundaries for interpreting the entire moral spectrum, introducing new categories such as sin, guilt, suffering, atonement, repentance, retribution, and salvation. Christianity appeals to those in need of an external point of support, namely the majority, offering consolation—the atonement of suffering and eternal bliss in the afterlife.

The eschatological orientation, that is, the anticipation of the end of the world, significantly influenced views on history in medieval philosophy, most vividly reflected in Augustine's work "The City of God." He formulated the idea of social development, a progressive movement from the imperfect "City of Man" to the ideal "City of God," thereby initiating the concept of historical time.

Medieval philosophy made a substantial contribution to the development of a number of key concepts and problems in philosophy, particularly the categories of faith and reason, ideas of social development, and historical time, while also making significant strides in ethical discourse, establishing doctrines on the spiritual world of humanity and universal values that remain relevant today.
