Logos
/LOH-gos/ · noun (Greek)
Word, speech, or reason; in philosophy, the rational principle ordering the cosmos and discoverable in human thought.
Where it comes from
From λέγω (legō, 'I speak, I gather'). Across pre-Socratic, Stoic, and Christian uses: word, account, reason, ratio, principle. Heraclitus made it the cosmic ordering principle.
A small question
Heraclitus said the logos is 'common to all' yet 'most people live as though they had a private understanding.' What did he mean?
