I have so many different personalities in me and I still feel lonely.

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

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

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

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.

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

Associate with men of good quality if you esteem your own reputation for it is better to be alone than in bad company.

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

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.
