In Genesis, it says that it is not good for a man to be alone but sometimes it is a great relief.

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 have so many different personalities in me and I still feel lonely.

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

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

Every man is born as many men and dies as a single one.

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

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

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

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