Physical advantages are compared with outward advantages in some such way as this: one may ask whether it is more desirable to have health than wealth; [external advantages with physical, thus: whether it is better to have wealth than extraordinary bodily strength;] while the physical advantages may be weighed against one another, so that good health is preferred to sensual pleasure, strength to agility. Outward advantages also may be weighed against one another: glory, for example, may be preferred to riches, an income derived from city property to one derived from the farm. 89 To this class of comparisons belongs that famous saying of old Cato's: when he was asked what was the most profitable feature of an estate, he replied: "Raising cattle successfully." What next to that? "Raising cattle with fair success." And next? "Raising cattle with but slight success." And fourth? "Raising crops." And when his questioner said, "How about money-lending?" Cato replied: "How about murder?"
