Alfieri
A usurper always distrusts the whole world.
Deep, sombre vengeance is the daughter of deep silence.
First thoughts are not always the best.
Joy surfeited turns to sorrow.
The heart does not lie.
There is a silence, the child of love, which expresses everything, and proclaims more loudly then the tongue is able to do; there are movements that are involuntary proofs of what the soul feels.
To err is human; but contrition felt for the crime distinguishes the virtuous from the wicked.
Well does Heaven have care that no man secures happiness by crime.
