Intelligence, behavior and internal processing

Abstract

Ned Block has recently adduced some new arguments to show that “psychologism is true and thus a natural behaviorist analysis of intelligence that is incompatible with psychologism is false”. He introduces a thought experiment in which a machine is programmed to exhibit intelligent-seeming behavior and appeals to our intuition that such a machine is nevertheless not really inteligent; he traces that intuition to the fact that the machine is being thought of as operating with internal processes that, first, lack a certain internal structure with a certain kind of complexity and, second, are in a certain sense mechanical, reflecting only the programmer’s intelligence. I argue against Block both that the mistakes the source and nature of our intuition and that the conclusion he draws concerning psychologism does not follow. While the intuition he appeals to may show that behaviorism is false, that is not equivalent to showing that psychologism in the sense intended by Block is true.
