About this book

What happens when a young man treats another person's heart as an experiment?

Adrien Sixte lives quietly among his books, certain that human choices follow natural causes. Robert Greslou, a gifted and proud young reader, takes that belief as a guide to life. In Paul Bourget's The Disciple, the distance between a philosopher's study and a prison cell becomes a troubling question: what responsibility does a thinker bear for another person's acts?

As tutor in the Marquis de Jussat's household, Greslou enters a world of trust, honor and loyalty. His attention turns to Charlotte, the Marquis's sheltered daughter. He wants to test whether arranging causes can produce a chosen feeling. With Greslou accused of a serious crime, documents and his own account from confinement draw you into the thought behind the act.

What you’ll discover

  • Ideas with human consequences Follow a theory beyond the study, where other people must bear its weight.
  • A proud young disciple Enter Greslou's searching account of a mind that turns belief into a dangerous experiment.
  • Trust under pressure Meet Charlotte de Jussat, whose sheltered world becomes the setting for Greslou's test.
  • A philosopher's moral burden Consider whether Sixte can separate the books he writes from the choices they inspire.
  • Confession and consequence Explore a layered narrative that brings psychological scrutiny to questions of guilt and blame.

Who will love it

You will enjoy this book if you like psychological novels, courtroom suspense, nineteenth-century Paris and the old argument over whether ideas shape conduct.

In short

Why would a quiet philosopher who never reads a newspaper board a night train to a provincial court? Because a young man he met only twice stands accused of poisoning a girl, and that young man says he learned to think from the philosopher's books.

What is The Disciple by Paul Bourget about?

It tells of a Paris philosopher whose pupil, a young tutor, is accused of poisoning a girl. The pupil's confession shows how the master's ideas shaped him, and the philosopher must face what he owes to the mind he has taught.

Who is Adrien Sixte in The Disciple?

Sixte is a fictional philosopher, born in Nancy, who lives in a quiet Paris street, never reads newspapers and writes books claiming that human acts are fixed. He is modeled on thinkers of Bourget's day, such as Taine and Spencer.

Is The Disciple based on a true story?

The characters and the trial are invented, though Bourget says in his dedication that similar events had occurred in real life. He finished it in 1889 as a study of how ideas can shape young minds.
