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

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.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

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

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

I paint self-portraits because I am so often alone, because I am the person I know best.

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.

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

The capacity for not feeling lonely can carry a very real price, that of feeling nothing at all.
