Abstract

The question of the so-called collective hallucination is neither as arcane nor as irrelevant to everyday life as it might first appear. On the contrary, it illuminates a much larger philosophical issue. In Group Psychology and the Analysis of the Ego, his 1921 book devoted to the relationship between individual and group psychology, Sigmund Freud lamented that there was still “no explanation of the nature of suggestion, that is, of the conditions under which influence without adequate logical foundation takes place.”2 What the science of psychology lacked, in other words, was an understanding of ideological transference—the process by which one individual imposed his or her beliefs and convictions on another. How did an idea spread, so to speak, from one person to the next, resulting in the formation of a group consciousness? The phenomenon of the collective hallucination puts the issue starkly—if ambiguously—in relief. If a ghost or apparition can be said to represent, in Freud’s terms, an idea “without adequate logical foundation,” a delusion, then the process by which two people convince each other that they have seen one—and in turn attempt to convince others—might be taken to epitomize the formation of ideology itself.In what follows I shall examine a case of collective hallucination—certainly the most notorious and well documented in the annals of modern psychical research—precisely as a way of spotlighting this larger problem. My goal in so doing is not so much to expose the folly of people who claim to see ghosts but the difficulty that inevitably besets anyone who attempts to debunk such claims on supposedly rationalist grounds. For in the absence of any satisfying explanation of how such “folly” spreads—how a private delusion becomes a folie à deux —the labors of the skeptic are doomed to result only in a peculiar rhetorical and epistemological impasse. 2.
