“wrote, “If a Huron’s soul could have inherited Montesquieu’s brain, Montesquieu would still create.” The native North American was an Enlightenment paradigm of the savage, yet if his soul were joined to Montesquieu’s brain, then one of the era’s greatest thinkers would, for intellectual purposes at least, be still alive. It did not matter that the soul and body were those of a “primitive,” provided the brain was the philosopher’s own. In short, the conviction that the brain is the only organ indispensable for personal identity emerged independently or, at most, marginally connected to empirical neuroscientific advances. Bonnet’s 1760 statement about Montesquieu and the Huron declares exactly the same thing as Puccetti’s aphorism of 1969, “Where goes a brain, there goes a person,” or Gazzaniga’s confident assertion of 2005, “you are your brain.” A good number of twentieth- and twenty-first-century (neuro)scientists and (neuro)philosophers claim that their convictions about the self are based on neuroscientific data. That may be so for them personally. Historically, however, things happened the other way around: Brainhood predated reliable neuroscientific discoveries and has all the appearance of having been a motivating factor of brain research. As it advanced, this research legitimized and reinforced the brainhood ideology.”
