There's a certain kind of lonely man who rejects love, because he believes that anyone who offers it wouldn't be a lover worth having.

Men are said to desire women, Severian. Why do they despise the women they obtain?

We choose--or choose not--to be alone when we decide whom we will accept as our fellows, and whom we will reject. Thus an eremite in a mountain is in company, because the birds and coneys, the initiates whose words live in his 'forest books,' and the winds--the messengers of the Increate--are his companions. Another man, living in the midst of millions, may be alone, because there are none but enemies and victims around him.

Imagine a man who stands before a mirror; a stone strikes it, and it falls to ruin all in an instant. And the man learns that he is himself, and not the mirrored man he had believed himself to be.
