"I walked on to the next corner, sat on a bench at a bus stop, and read in my new book about Heraclitus. All things flow like a river, he said; nothing abides. Parmenides, on the other hand, believed that nothing ever changed, it only seemed so. Both views appealed to me."

"[With Heraclitus] we see land; there is no proposition of Heraclitus which I have not adopted in my Logic."

"In... Heraclitus... Becoming occupies the foremost place. He regarded that which moves, the fire, as the basic element. The difficulty, to reconcile the... one fundamental principle with the infinite variety of phenomena, is solved... by recognizing... strife of... opposites is... a kind of harmony. ...[T]he world is ...one and many ..."the opposite tension" of ...opposites ...constitutes the unity of the One. He says: "...war is common to all and strife is justice ...all things come into being and pass away through strife." ...[T]hat infinite and eternal undifferentiated Being ...cannot ...explain the infinite variety of things. This leads to the antithesis of Being and Becoming and ...to the solution of Heraclitus ...change ...is the fundamental principle; the "imperishable change, that renovates the world," as the poets have called it. But ...change ...is not a material cause and therefore is represented ...by the fire ...both matter and a moving force. ...[[Physics|[P]hysics]] is ...extremely near to ...Heraclitus ...[i]f we replace ..."fire" by ..."energy" ...Energy is a substance, since its total ...does not change, and ...elementary particles can ...be made from this ...Energy may be called the fundamental cause for all change in the world. ...Energy is ...that which moves; it may be called the primary cause of all change, and ...can be transformed into matter or heat or light. The strife between opposites in the philosophy of Heraclitus can be found in the strife between two different forms of energy."

"It was not Zeno, the founder of the Stoics, alone, who taught that the Universe evolves, and its primary substance is transformed from the state of fire into that of air, then into that of water, etc. Heraclitus of Ephesus maintained that the one principle that underlies all phenomena in Nature is fire. The intelligence that moves the Universe is fire, and fire is intelligence. And while Anaximenes said the same of air, and Thales of Miletus (600 years b.c.) of water, the Esoteric Doctrine reconciles all these philosophers, by showing that though each was right, the system of none was complete."

"Of Every One-Hundred Men, Ten shouldn't even be there, Eighty are nothing but targets, Nine are real fighters... We are lucky to have them... They make the battle. Ah but the One, One of them is a Warrior... and He will bring the others back."

"Many statements paraphrase or extend upon his famous assertions that "everything changes" in ways which arguably diverge from valid translation, and yet have become widely attributed to Heraclitus:"

"Opposition brings concord. Out of discord comes the fairest harmony."
