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.

Living alone makes it harder to find someone to blame.

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.

I love to be alone. I never found the companion that was so companionable as solitude.

I never said, 'I want to be alone.' I only said, 'I want to be left alone.' There is all the difference.

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

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

Even in the presence of others he was completely alone.

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