The devil is not as black as he is painted.

... Nessun maggior dolore Che ricordarsi del tempo felice Nella miseria. (There is no greater pain than to remember a happy time when one is in misery.)

The human race finds itself in a better situation when it has the higher level of freedom.

Through me you go into a city of weeping; through me you go into eternal pain; through me you go amongst the lost people

Doubting pleases me no less than knowing

Go right on and listen as thou goest.

L'amor che move il sole e l'altre stelle (The love that moves the sun and the other stars)
