Heraclitus

“God is day and night, winter and summer, war and peace, surfeit and hunger.”

“There is nothing permanent except change.”

“Our envy always lasts longer than the happiness of those we envy.”

“Nothing endures but change.”

“You cannot step into the same river twice.”

“Much learning does not teach understanding.”

“Change alone is unchanging.”

“To God everything is beautiful, good, and just; humans, however, think some things are unjust and others just.”

“No man ever steps in the same river twice, for it's not the same river and he's not the same man.”

“Good character is not formed in a week or a month. It is created little by little, day by day. Protracted and patient effort is needed to develop good character.”

“The best people renounce all for one goal, the eternal fame of mortals; but most people stuff themselves like cattle.”
