le petit prince

One must command from each what each can perform, the king went on. "Authority is based first of all upon reason. If you command your subjects to jump into the ocean, there will be a revolution. I am entitled to command obedience because my orders are reasonable."
" Then my sunset?" insisted the little prince, who never let go of a question once he had asked it.
"You shall have your sunset. I shall command it. But I shall wait, according to my science of government, until conditions are favorable."
