Pythagoras
<p>The Greeks always held to the existence of the Universal Life Principle, calling it by various names. The very term, "The Cosmos," was used by the Stoics and others to represent the idea of the <i>anima mundi</i> or "world-soul." Heraclitus held to the "world-spirit" which he symbolized as flame. Pythagoras, in his exoteric or popular teachings taught the doctrine of the Life Principle, symbolizing it as light or flame. Other schools recognized the existence of this One Life Principle calling it "Being," a term which has persisted in modern philosophy. (Source 1).</p>
