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.

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

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

Only the lonely know the way I feel tonight.

I paint self-portraits because I am so often alone, because I am the person I know best.

It is strange to be known so universally and yet to be so lonely.

I don't want to be alone, I want to be left alone.

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

All men's miseries derive from not being able to sit in a quiet room alone.

You cannot be lonely if you like the person you're alone with.
