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

A man content to go to heaven alone will never go to heaven.

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

Unless we love and are loved, each of us is alone, each of us is deeply 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.

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

Yes, I guess you could say I am a loner, but I feel more lonely in a crowed room with boring people than I feel on my own.

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

Only the lonely know the way I feel tonight.
