In his treatise on rhetoric, Aristotle considers the requisite building blocks of rhetoric as well as its existent contemporaneous forms. He also examines the subjects of politics, virtue, happiness, and morality in his customary common-sense way.
“Justice, courage, self-control, magnanimity, magnificence, and all other similar states of mind, for they are virtues of the soul. Health, beauty, and the life, for they are virtues of the body and produce many advantages…”
“In regard to war and peace, the orator should be acquainted with the power of the State, how great it is already and how great it may possibly become; of what kind it is already and what additions may possibly be made to it; further, what wars it has waged and its conduct of them. These things he should be acquainted with, not only as far as his own State is concerned, but also in reference to neighboring States, and particularly those with whom there is a likelihood of war, so that towards the stronger a pacific attitude may be maintained, and in regard to the weaker, the decision as to making war on them may be left to his own State.”
“…it is useful not only to understand what form of government is expedient by judging in the light of the past, but also to become acquainted with those in existence in other nations, and to learn what kinds of government are suitable to what kinds of people.”
“Let us then define happiness as well-being combined with virtue, or independence of life, or the life that is most agreeable combined with security…”
“Internal goods are those of mind and body; external goods are noble birth, friends, wealth, honor. To these we think should be added certain capacities and good luck; for on these conditions life will be perfectly secure.”
