If, then, the life of the statesman and the soldier, though they surpass all other virtuous exercises in nobility and grandeur, are not leisurely occupations, and aim at some ulterior end, and are not desired merely for themselves, but the exercise of the reason seems to be superior in seriousness (since it contemplates truth), and to aim at no end beside itself, and to have its proper pleasure (which also helps to increase the exercise), and further to be self-sufficient, and leisurely, and inexhaustible (as far as anything human can be), and to have all the other characteristics that are ascribed to happiness, it follows that the exercise of reason will be the complete happiness of man, i.e. when a complete term of days is added; for nothing incomplete can be admitted into our idea of happiness.
