Benjamin Constant said this quote

Art for art's sake, with no purpose, for any purpose perverts art. But art achieves a purpose which is not its own. (1804)

~ Benjamin Constant

Woe to the man who in the first moments of a love-affair does not believe that it will last forever! Woe to him who even in the arms of some mistress who has just yielded to him maintains an awareness of trouble to come and foresees that he may later tear himself away!

~ Benjamin Constant

Every time government attempts to handle our affairs, it costs more and the results are worse than if we had handled them ourselves.

~ Benjamin Constant

The actions of government, we are told, bear down only on imprudent souls who provoke them. The man who resigns himself and keeps silent is always safe. Reassured by this worthless and specious argument, we do not protest against the oppressors. Instead we find fault with the victims. Nobody knows how to be brave even prudentially. Everyone stays silent, keeping his head low in the self-deceiving hope of disarming the powers that be by his silence. People give despotism free access, flattering themselves they will be treated with consideration. Eyes to the ground, each person walks in silence the narrow path leading him safely to the tomb.
