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

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

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

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.

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

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

Love is our true destiny. We do not find the meaning of life by ourselves alone - we find it with another.

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.

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