Will Self - with a nod to the "valetudinarian pop-person, Morrissey" - poses the question "Does the mind rule the body or the body rule the mind?"

Before 1960, he says, "a Briton could probably go their entire life without encountering a psychiatrist or a psychoanalyst - let alone a modish psychotherapist". But not any more.

Will ponders what role these "psy-professions" play in contemporary Britain.
