Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard. ('What else could it be?') I was amused to see that Sherrington, the great British neuroscientist, thought that the brain worked like a telegraph system.

Considering the enormous range of human knowledge, from intimate personal knowledge of specific individuals to the complexities of organizations and the subtleties of feelings, it is remarkable that one speck in this firmament should be the sole determinant of whether someone is considered knowledgeable or ignorant in general.
