How Augustine and Aquinas Christianized Plato and Aristotle’s Philosophies

Augustine and Plato

The Theory of Forms

Plato: posited a world of ideal Forms that represented the true essence of things. Augustine: adapted this idea by linking the Forms to the divine mind. He suggested that the Forms exist in God and our knowledge of them is a reflection of our participation in divine truth. This aligns with Christian theology where ultimate truth and goodness are found in God.

The Nature of Reality

Plato: emphasized the distinction between the material and the immaterial world. Augustine: reinforced this dualism but framed it within the context of creation, arguing that the material world is good because it is created by God. He also emphasized the fallen nature of the material world due to sin which diverges from Plato’s more optimistic view of the physical realm.

The Soul

Plato: viewed the soul as immortal and pre-existing its physical body. Augustine: maintained the immortality of the soul but emphasized its need for redemption through Christ. He argued that the soul is created by God and that its ultimate purpose is to seek union with Him.

Ethics and the Good

Plato: defined the Good as the ultimate principle a Form that transcends all other Forms. Augustine: identified the Good with God, arguing that true goodness is found in a relationship with Him. Moral goodness is thus tied to divine will and revelation rather than a rational understanding of the Good.

Aquinas and Aristotle

Nature of God

Aristotle: described God as the unmoved mover, a necessary being that is pure actuality. Aquinas: built on this by integrating Aristotle's concept of God into a Christian framework, arguing that God is not only the unmoved mover but also a personal God who desires a relationship with humanity. He emphasized God's providence and the role of divine revelation.

Ethics and Virtue

Aristotle: believed in virtue ethics, where the highest good is eudaimonia (flourishing or happiness) achieved through virtuous living. Aquinas: adapted this by connecting virtue to divine law. He argued that true happiness is found in the Beatific Vision, the ultimate union with God, and that virtues are infused by God's grace, not merely cultivated through reason.

Natural Law

Aristotle: had a naturalistic approach to ethics based on human reason and observation of nature. Aquinas: Christianized this by proposing that natural law is part of God's eternal law, accessible through reason but ultimately grounded in divine authority. He argued that human beings can discern moral truth through reason but it is ultimately aligned with divine will.

Faith and Reason

Aristotle: valued reason as the primary means of acquiring knowledge. Aquinas: emphasized the harmony between faith and reason, arguing that while faith transcends reason, it does not contradict it. He believed that reason can lead to certain truths about God but divine revelation is necessary for a complete understanding of faith.

Conclusion

Both Augustine and Aquinas took foundational ideas from Plato and Aristotle and reinterpreted them within a Christian context. Augustine focused more on the relationship between God and the soul, emphasizing the need for divine grace, while Aquinas sought to integrate reason with faith, grounding ethics and metaphysics in a comprehensive vision of God as both rational and personal. Their works laid the groundwork for much of medieval Christian thought and continue to influence Christian philosophy today.
