“All are one”

“Wisdom is the oneness of mind that guides and permeates all things.”

“All is flux”

“The waking have one world in common; sleepers have each a private world of his own.”

“The road up and the road down is one and the same.(ὁδὸς ἄνω κάτω μία καὶ ὡυτή)—Fragment 60”

“Even what those with the greatest reputation for knowing it all claim to understand and defend are but opinions.”

“It is necessary to understand that war is common, strife is customary, and all things happen because of strife and necessity.”
