Roman philosophy evolved, blending Greek ideas with mysticism and pragmatism. Neoplatonism, founded by Plotinus, saw reality as emanating from "The One." It influenced Christian theology and encouraged spiritual introspection.

Stoicism, emphasizing reason and virtue, appealed to Roman values of duty and resilience. It provided a practical ethical framework for governance and personal conduct, shaping Roman political thought and social attitudes.
