The concept of "virtus" also tended to be a concept of morality as far as politics were concerned. This could range from the very literal definition of manliness seen in aggression and the ruthless acquisition of money, land, and power, or the lighter, more idealistic political meaning which almost took on the extended meaning of "pietas", a man who was morally upright and concerned with the matters of the state. Plautus in "Amphitruo" contrasted "virtus" and "ambitio". Virtus is seen as a positive attribute, though "ambitio" itself is not necessarily a negative attribute but is often associated with negative methods such as bribery. Plautus said that just as great generals and armies win victory by "virtus", so should political candidates. "Ambitio" "is the wrong method of reaching a good end." Part of "virtus", in the political sphere was to deal justly in every aspect of one's life, especially in political and state matters.
