M. Tullius Cicero, De Officiis
Walter Miller, Ed.

[151] But the professions in which either a higher¹ degree of intelligence is required or from which no small benefit to society is derived—medicine and architecture, for example, and teaching—these are proper for those whose social position they become. Trade, if it is on a small scale, is to be considered vulgar; but if wholesale and on a large scale, importing large quantities from all parts of the world and distributing to many without misrepresentation, it is not to be greatly disparaged. Nay, it even seems to deserve the highest respect, if those who are engaged in it, satiated, or rather, I should say, satisfied with the fortunes they have made, make their way from the port to a country estate, as they have often made it from the sea into port. But of all the occupations by which gain is secured, none is better than agriculture, none more profitable, none more delightful, none more becoming to a freeman. But since I have discussed this quite fully in, my Cato Major, you will find there the material that applies to this point.
