Julius Hertzfeld is a distinguished psychotherapist when a sudden confrontation with his own mortality forces him to re-examine his life and work. Has he really made an enduring difference to the lives of his patients? And what about those he's failed - what has happened to them? His attempt to make sense of the past places him on a collision course with former patient Philip Slate a handsome but arrogant and misanthropic sex addict whom he had treated, unsuccessfully, 23 years before.In a profound challenge to Julius's professional status, Philip claims to have cured himself by reading the works of philosopher Arthur Schopenhauer. Furthermore, he has become a philosophical counsellor, and asks Julius to act as his professional supervisor in order to obtain a license to practise.Reluctantly, Julius agrees, and they strike a Faustian bargain - one which threatens to undermine his career and the well-being of his patients, but also brings with it the potential for extraordinary personal change through a unique combination of psychotherapy and philosophy.
