Gratitude is the sign of noble souls.

Self-conceit may lead to self destruction.

It is with our Passions, as it is with Fire and Water, they are 'Good Servants,' but 'Bad Masters.'

We often give our enemies the means for our own destruction.

Those who voluntarily put power into the hands of a tyrant ... must not wonder if it be at last turned against themselves.

Every man carries two bags about him, one in front and one behind, and both are full of faults. The bag in front contains his neighbors' faults, the one behind his own. Hence it is that men do not see their own faults, but never fail to see those of others.

We would often be sorry if our wishes were gratified.
