What were the key ideas of Augustine of Hippo?

Augustine of Hippo, a prominent figure in Medieval Philosophy, had several key ideas. Some of his main ideas include:

1. Original Sin: Augustine believed that all humans are born with original sin, inherited from Adam and Eve's disobedience in the Garden of Eden. This sin taints human nature and separates individuals from God.

2. Divine Grace: Augustine emphasized the importance of divine grace in the salvation of individuals. He argued that humans cannot achieve salvation through their own efforts but rather through the grace of God.

3. Free Will: Augustine proposed that humans possess free will, but due to the effects of original sin, their will is weakened and inclined towards evil. He believed that only through divine grace can individuals overcome this inclination and choose the path of righteousness.

4. The City of God: Augustine developed the concept of the "City of God," which refers to the spiritual realm and the eternal city of God. He contrasted this with the earthly city, which represents human society and is subject to corruption and sin.

5. The Problem of Evil: Augustine grappled with the problem of evil, attempting to reconcile the existence of evil with the belief in an all-powerful and benevolent God. He argued that evil is a result of the misuse of free will and that God allows it as a means to bring about a greater good.

These are just a few of the key ideas associated with Augustine of Hippo. His works had a profound influence on Medieval Philosophy and continue to be studied and debated by philosophers today.
