Institutio Oratoria

For the precepts that are enjoined upon us are not so complex or so numerous that they may be acquired by little more than a few years' study. It is repugnance to learn that makes such labour long. For if you will only believe it, you will quickly learn the principles that shall lead you to a life of virtue and happiness. For nature brought us into the world that we might attain to all excellence of mind, and so easy is it for those to learn who seek for better things, that he who directs his gaze aright will rather marvel that the bad should be so many.

For as water is the natural element of fish, dry land for creatures of the earth and the circumambient atmosphere for winged things, even so it should be easier to live according to nature than counter to her will. As regards other accomplishments, there are plenty of years available for their acquisition, even though we measure the life of man not by the span of age, but by the period of youth. For in every case order and method and a sense of proportion will shorten our labour.
