Greek Mythology Notes

Logos

concept
Λόγος
reason, word, principle

The rational principle governing the cosmos — simultaneously word, reason, argument, and proportion.

The Myth

Logos is perhaps the most untranslatable word in Greek philosophy. Heraclitus used it to describe the underlying rational order of the universe. The Stoics made it the active, intelligent principle pervading all reality. For Aristotle, logos was the capacity for rational speech that distinguished humans from animals. In rhetoric, logos meant logical argument, as opposed to emotional appeal (pathos) or character (ethos). The Gospel of John famously opens "In the beginning was the Logos," fusing Greek philosophy with Judeo-Christian theology.
