Do not learn more than you absolutely need to get through life.

For a man to attain to an eminent degree in learning costs him time, watching, hunger, nakedness, dizziness in the head, weakness in the stomach, and other inconveniences.

Learning makes a man fit company for himself as well as for others.

The years teach us much the days never knew.

Learning is not attained by chance. It must be sought for with ardor and attended to with diligence.

In the end we retain from our studies only that which we practically apply.

Erudition can produce foliage without bearing fruit.

This type of man who is devoted to the study of wisdom is always most unlucky in everything, and particularly when it comes to procreating children; I imagine this is because Nature wants to ensure that the evils of wisdom shall not spread further throughout mankind.

A little knowledge is a dangerous thing. Drink deep, or taste not the Pierian spring; There shallow draughts intoxicate the brain; And drinking largely sobers us again.

For the things we have to learn before we can do them, we learn by doing them.
