ON HYPNOSIS, SIMULATION, AND FAITH THE PROBLEM OF POST-HYPNOTIC SUGGESTION IN FRANCE 1884-1896 by André Robert LeBlanc Ph-D. 2000 Institute for the History and Philosophy of Science and Technology University of Toronto ABSTRACT The first half of this dissertation demonstrates how the concept of dissociation originated as a solution to the problem of post-hypnotic suggestion. The second half continues with investigations into hypnosis and simulation and concludes with an analogy between hypnosis and religion. Zn 1884, the philosopher Paul Janet introduced the problern of post- hypnotic suggestion, Give a hypnotic subject the post-hypnotic command to retum in 23 days. Awake, the subject remembers nothing yet he nonetheless fulfills the command to retum. The problem then is this: how does the subject count 13 days without knowing it? The philosopher and psychologist, Pierre Janet (Paul's nephew) proposed the concept of dissociation as a solsrtion in 1886 which is discussed in the second chapter, Pierre Janet argued that a second consciousness kept track of time outside the awareness of the subject's main consciousness. Chapter 3 presents an alternative solution to the problem: the physician Hyppolite Bernheim and the philosopher Joseph Delboeuf argued in 1886 that subjects occasionally drifted into a hypno tic state in which they were reminded of the suggestion. Chapter 4 describes Janet's attempts to argue against this expianation. The fifth chapter demonstrates a logical flaw in the concept of dissociation and introduces the idea that hypnosis may well be a form of pretending. The theme of pretending is carried on in chapters 6 and 7 in relation to the impossibility of empirically confimihg or refuting simulation in hypnosis. The final two chapters build on Delboeuf's work using an analogy between hypnosis and religion. Drawing upon Pascal, it is argued that, like hypnosis, religious belief may weii contain an element of pretending in the way one's faith is produced and maintained. Chapter 8 relates hypnosis to what Pascal labeled "discourse concerning the machine" (Inf ni-rien): the notion that custom and habit, by a machine-like process, shape human thought and belief. Chapter 9 discusses Pascal's analysis of the differences between superstition and religion and applies it to our understanding of hypnosis, Acknowledgments The only way that 1 shall ever be able to repay my debt to m y supervisor will be to someday help my studeats as Ian Hacking helped me. This realisation is enough to dissuade me from becoming a professor as 1 doubt 1 could ever match his patience, energy and generosity. But I take courage in knowing that 1 could not have chosen a better role model. This applies doubly for my parents whose unconditional love and financial support have positively discouraged me from ever having children of my own- And yet, how else could I ever hope to repay t h e m ? 1 am hardly less demanding of my fnends and thank them d l for their encouragement and support throughout the several years of my Ph-D- 1 hope they forgive me if 1 do not include all their names here. 1 do wish, however, to single out every one who read and discussed my work with me during the past three years: Tara Abraham, Jean- François Auger, Jose Brumer, Steve Cohen, Csilla Dallos, Jay Foster, Valentina Fuentes, Car1 Gehriger, Danny Goldstick, Ross Inman, Yasir Kahn, Kenton Kroker, Pierre Gosselin, my parents Rosaire and Annette and my siblings Marc and Michelle, Laurent Lafontaine, Ji11 Lazenb y, Daryn Lehowc, André Levesque, Christian0 MartelIo, Francisco Morales, my "best bud" Richard Noiles, Claudia Pabon, David Pantalony, David Potiers, Gilles Poitras, Milena Pereira Ponde, Daniel and Maryse Roy, Pura Sanchez, Hervé, and Eldon Yellowhom. 1 am much indebted to OIiver Stunt for his outstanding proofreading job. 1 am profoundly grateful to Bryan Boddy for his friendship and many exceptional insights and discussions.

The second haif continues with investigations into hypnosis and simulation and concludes with a n analogy between hypnosis and religion. My account begins with the problem of post-hypnotic suggestion that was fomulated in 1884 by the philosopher Paul Janet (1823-1 899).
