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

Even in the presence of others he was completely alone.

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

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

Only the lonely know the way I feel tonight.

What a lovely surprise to finally discover how unlonely being alone can be.

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

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

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

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