rules. In the human brain, there is gullibility. How gullible are you? Is your
gullibility located in some "gullibility center" in your brain? Could a
neurosurgeon reach in and perform some delicate operation to lower your
gullibility, otherwise leaving you alone? If you believe this, you are pretty
gullible, and should perhaps consider such an operation.Mind vs. Brain
In coming Chapters, where we discuss the brain, we shall examine whether
the brain's top level-the mind-can be understood without understanding
the lower levels on which it both depends and does not depend. Are there
laws of thinking which are "sealed off" from the lower laws that govern the
microscopic activity in the cells of the brain? Can mind be "skimmed" off of
brain and transplanted into other systems? Or is it impossible to unravel
thinking processes into neat and modular subsystems? Is the brain more
like an atom, a renormalized electron, a nucleus, a neutron, or a quark? Is
consciousness an epiphenomenon? To understand the mind, must one go
all the way down to the level of nerve cells?Levels of Description, and Computer Systems 309
