All of our unhappiness comes from our inability to be alone.

All men's miseries derive from not being able to sit in a quiet room alone.

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

When so many are lonely as seem to be lonely, it would be inexcusably selfish to be lonely alone.

A man content to go to heaven alone will never go to heaven.

Unless we love and are loved, each of us is alone, each of us is deeply lonely.

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.

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

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

Even in the presence of others he was completely alone.
