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.

I finally faced the fact that it isn't a crime not having friends. Being alone means you have fewer problems.

We are all sentenced to solitary confinement inside our own skins, for life.

If you are lonely when you're alone, you are in bad company.

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

Only the lonely know the way I feel tonight.

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

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

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