Attempts to define intelligence. Also considers how human intelligence is to be investigated on the machine model.
Provides a point against the Turing Test conception of intelligence in the form of a hypothetical machine. This machine would contain all the responses to every possible question and chains of questions that the judge could ask, and simply returns the response that is stored in the machine. Each possible conversation would be a different path down this converstation “tree”.

is the judges first question, and is the machines first response, with all following letters alterating between judge and machine. The subscript dictates the specific message, of which there are a very large amount (not infinite because of the time limit of 1 hour for the test).
Block argues that this machine is obviously unintelligent not because of its behavior (it passes the turing test), but because of its competence and the way in which it processes information.
” labeling the sciences of the mind as “the behavioral sciences” … is like calling physics the science of meter readings.”
