XXVII. (148) And, says God, “I will bless her, and she shall be a mother of Nations;”{52}{genesis 17:16.} because, not only is generic virtue divided into its proximate species, and into individuals subordinate to the species, as if into nations; but also because, as there are nations of living animals, so in a manner are there nations of things, to which virtue is a very great advantage; (149) for all things which are devoid and destitute of wisdom are mischievous, just as all places upon which the sun does not shine are of necessity dark; for it is by virtue that a farmer is able to pay better attention to his crops, and by virtue that a charioteer drives his chariot in the horse-races so as to avoid falling; and by virtue too, that a pilot and a steersman guides his vessel in its voyage. (150) Virtue again has caused houses, and cities, and countries to be inhabited in a better manner, making men competent to manage houses and cities, and fit to associate with one another. Virtue has also introduced most excellent laws, and has sown the seeds of peace everywhere; since, from the contrary habit, things of a contrary character do naturally arise–war, lawlessness, bad constitutions, confusion, unnecessary voyages, overthrows, that which, in science, is the most grievous of all diseases, namely, cunning, from which, instead of art, all kinds of evil artifice has flowed. Very necessarily, therefore, will virtue be divided among all nations, which are large and collected systems of living beings and things taken together, for the advantage of those who receive her.
