And of this nature Happiness is mostly thought to be, for this we choose always for its own sake, and never with a view to anything further: whereas honour, pleasure, intellect, in fact every excellence we choose for their own sakes, it is true (because we would choose each of these even if no result were to follow), but we choose them also with a view to happiness, conceiving that through their instrumentality we shall be happy: but no man chooses happiness with a view to them, nor in fact with a view to any other thing whatsoever. — Aristotle, Ethics
