La Rochefoucauld

Self-love is subtler than the subtlest man in the world.

It is more shameful to distrust one's friends than to be deceived by them.

Some people would never have fallen in love if they had never heard of love.

We all have strength enough to endure the troubles of others.

The weak cannot be honest.

Greater virtues are needed to bear good fortune than bad.

Not many know how to be old.

We often forgive those who bore us, but we can never forgive those who find us boring.

In the misfortunes of even our best friends, we always find something not wholly displeasing.

La Rochefoucauld, Maxims
