Tao Te Ching

“The Emperor Constantine was a villain; a patricide who had smothered his wife in a bath, cut his son's throat, assassinated his father-in-law, his brother-in-law, and his nephew. A man puffed up with pride and immersed in pleasure, a detestable tyrant like his children—but he was a man of sense. He would not have obtained the Empire and subdued all his rivals had he not reasoned justly.”

— Voltaire, François-Marie Arouet 1694 – 1778 CE via Naves
from Philosophical Letters (1730)
