Augustine’s Two Cities and Plato’s Cave: Exploring History and Knowledge

Philosophy of History

Christianity posits that mankind, united in the first man, disobeyed God. Since then, humanity has been caught in a struggle between two loves: love of God (amor Dei) and love of self (amor sui). St. Augustine highlights this struggle between love and pride, sin and redemption, liberty and divine grace. This conflict transcends the natural order, shaping the inner life of each individual, as salvation or eternal condemnation is at stake.

Just as there are those who love God above

Impressions of a supposed reality (the world) are beyond our minds and do not have any print or experience. No impressions can come from an alleged cause or origin of the prints. This is phenomenism and skepticism. Descartes said that the foundation of knowledge is innate ideas.

Aristotle’s Philosophy: Act, Potency, Physics, and Cosmology

Filo 2.2 & 4. Potency and Act

The distinction between potency and act addresses the physical explanation of movement. While Parmenides saw reality as static and Heraclitus viewed it as constant evolution, Plato proposed two worlds: the Sensible (changeable) and the Intelligible (immutable ideas). Aristotle, however, introduced Being (act) and a form of non-being: potency. He believed this explained change in substance, with two aspects: “what is” (act, e.g., a tree) and “what it can become” (
