Book excerpt: When several things are ordained to one thing, one of them must rule or govern and the rest be ruled or governed, as the Philosopher, teaches in the Politics. This is evident in the union of soul and body, for the soul naturally commands and the body obeys. The same thing is true of the soul’s powers, for the concupiscible and irascible appetites are ruled in a natural order by reason. Now all the sciences and arts are ordained to one thing, namely, to man’s perfection, which is happiness. Hence one of these sciences and arts must be the mistress of all the others, and this rightly lays claim to the name wisdom; for it is the office of the wise man to direct others. Aeterna Press
