Our virtues are dearer to us the more we have had to suffer for them. It is the same with our children. All profound affection admits a sacrifice.

We are dismayed when we find that even disaster cannot cure us of our faults.

All that causes one man to differ from another is a very slight thing. What is it that is the origin of beauty or ugliness, health or weakness, ability or stupidity? A slight difference in the organs, a little more or a little less bile. Yet this more or less is of infinite importance to men; and when they think otherwise they are mistaken.

Few people are modest enough to be estimated at their true worth.

There is nothing that fear and hope does not permit men to do.
