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

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

The only real progress lies in learning to be wrong all alone.

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.

It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone.

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

Alone we can do so little together we can do so much.

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