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.

Absolutely lonely people have few personal interactions of any kind.

Even in the presence of others he was completely alone.

The time you feel lonely is the time you most need to be by yourself.

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

Only the lonely know the way I feel tonight.

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

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

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

Love is our true destiny. We do not find the meaning of life by ourselves alone - we find it with another.
