A man's foibles are what makes him lovable.

It is natural to man to regard himself as the object of the creation, and to think of all things in relation to himself, and the degree in which they can serve and be useful to him.

Man's restlessness makes him strive.

Time flies, and what is past is done.

No man learns to know his inmost nature by introspection, for he rates himself sometimes too low, and often too high, by his own measurement. Man knows himself only by comparing himself with other men; it is life that touches his genuine worth.

The philosophers must station themselves in the middle.

We know accurately only when we know little, with knowledge doubt increases.
