Janet Malcolm said this quote

The concept of the psychopath is, in fact, an admission of failure to solve the mystery of evil—it is merely a restatement of the mystery—and only offers an escape valve for the frustration felt by psychiatrists, social workers, and police officers, who daily encounter its force.

Before the magisterial mess of Trevor Thomas's house, the orderly houses that most of us live in seem meagre and lifeless -- as, in the same way, the narratives called biographies pale and shrink in the face of the disorderly actuality that is a life. The house also stirred my imagination as a metaphor for the problem of writing. Each person who sits down to write faces not a blank page but his own overfilled mind. The problem is to clear out most of what is in it . . . The goal is to make a space where a few ideas and images and feelings may be so arranged that a reader will want to linger awhile among them, rather than to flee, as I wanted to flee from Thomas's house.

He never asked me what I thought, and I never told him what I thought, because in my view that's the way a journalist ought to behave. You ought not to be going around to people volunteering your feelings. That's daily journalism.

~ Janet Malcolm

Unlike other relationships that have a purpose beyond themselves and are clearly delineated as such (dentist-patient, lawyer-client, teacher-student), the writer-subject relationship seems to depend for its life on a kind of fuzziness and murkiness, if not utter covertness, of purpose. If everybody put his cards on the table, the game would be over. The journalist must do his work in a kind of deliberately induced state of moral anarchy.
