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

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

Absolutely lonely people have few personal interactions of any kind.

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

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

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

Before the throne of the Almighty, man will be judged not by his acts but by his intentions. For God alone reads our hearts.

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