We're all in this alone.

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

Maybe each human being lives in a unique world, a private world, a world different from those inhabited and experienced by all other humans.

Better be alone than in bad company.

Solitude is as needful to the imagination as society is wholesome for the character.

Solitude is the profoundest fact of the human condition. Man is the only being who knows he is alone.

There are places and moments in which one is so completely alone that one sees the world entire.

Only in solitude do we find ourselves; and in finding ourselves, we find in ourselves all our brothers in solitude.

No man should go through life without once experiencing healthy, even bored solitude in the wilderness, finding himself depending solely on himself and thereby learning his true and hidden strength.

Here I am, a wild beast cut off from his companions.
