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

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

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.

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

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.

There are places and moments in which one is so completely alone that one sees the world entire.

Even in the presence of others he was completely alone.

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

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