Upon this point all speculative politicians will agree, that the happiness of society is the end of government, as all divines and moral philosophers will agree that the happiness of the individual is the end of man. From this principle it will follow that the form of government which communicates ease, comfort, security, or, in one word, happiness, to the greatest numbers of persons, and in the greatest degree, is the best. All sober inquirers after truth, ancient and modern, pagan and Christian, have declared that the happiness of man, as well as his dignity, consists in virtue.
