There are two levers for moving men, interest and fear.

In all of us, even in good men, there is a lawless wild-beast nature, which peers out in sleep.

Beware of driving men to desperation. Even a cornered rat is dangerous.

Our credulity is a part of the imperfection of our natures. It is inherent in us to desire to generalize, when we ought, on the contrary, to guard ourselves very carefully from this tendency.

It is a mistake, too, to say that the face is the mirror of the soul. The truth is, men are very hard to know, and yet, not to be deceived, we must judge them by their present actions, but for the present only.

I do not believe it is in our nature to love impartially. We deceive ourselves when we think we can love two beings, even our own children, equally. There is always a dominant affection.
