All art is concerned with coming into being; for it is concerned neither with things that are, or come into being by necessity, nor with things that do so in accordance with nature.
AristotleWe give up leisure in order that we may have leisure, just as we go to war in order that we may have peace.
AristotleThose who have the command of the arms in a country are masters of the state, and have it in their power to make what revolutions they please. [Thus,] there is no end to observations on the difference between the measures likely to be pursued by a minister backed by a standing army, and those of a court awed by the fear of an armed people.
Aristotle
