All men's misfortunes spring from their hatred of being alone.

Every man must do two things alone he must do his own believing and his own dying.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

There are places and moments in which one is so completely alone that one sees the world entire.

We are all sentenced to solitary confinement inside our own skins, for life.

The time you feel lonely is the time you most need to be by yourself.

Absolutely lonely people have few personal interactions of any kind.

If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.

Every man is born as many men and dies as a single one.

As I get older I'm more and more comfortable being alone.
