However, the concept of inspiration has roots in ancient Greek philosophy, specifically in the word "entheos" (ἔνθεος), which literally means "having a god within". This referred to the state of being filled with divine or spiritual influence, a state of heightened creativity and insight.
While "entheos" itself isn't directly the origin of "inspiration", it represents the Greek conceptual foundation of the idea of inspiration, that is, being filled with a divine force that brings forth creative power and knowledge.
