Living alone makes it harder to find someone to blame.

It is strange to be known so universally and yet to be so lonely.

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

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

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

As I get older I'm more and more comfortable being alone.

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

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

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

Even in the presence of others he was completely alone.
