The purpose of the whole [the Comedy] and of this portion [the Paradiso] is to remove those who are living in this life from the state of wretchedness, and to lead them to the state of blessedness.
Do not be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better. What if they are a little coarse and you may get your coat soiled or torn? What if you do fail, and get fairly rolled in the dirt once or twice? Up again, you shall never be so afraid of a tumble.
Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.
The only thing that really matters is that there be an action of goodness, love and intelligence in living. Is goodness individual or collective, is love personal or impersonal, is intelligence yours, mine or somebody else? If it is yours or mine then it is not intelligence, or love, or goodness. If goodness is an affair of the individual or of the collective, according to one's particular preference or decision, then it is no longer goodness.
I don't count my sit-ups. I only start counting when it starts hurting. That is when I start counting, because then it really counts. That's what makes you a champion.
