Review of Hawkins’s “On Intelligence”

Posted in Book reviews, Mind by KevinCK on July 8, 2009

Jonathan Hawkins, the creator of the PalmPilot and Graffiti handwriting software it uses, has written a book outlining a very interesting theory of what intelligence is. “On Intelligence” takes a non-behavioral (intelligence is not the same as intelligent behavior) and non-computational (intelligence is more than the ability to compute) approach to intelligence. Instead, he views intelligence as the ability to make predictions by taking stored memories and predicting future outcomes based on those memories. Hawkins suggests, uncontroversially, that this ability comes exclusively from the neocortex and, more controversially, that all operations we call intelligent can be reduced to the ability to make and adjust predictions.

Here is my review of the book, which I gave a four out of  five stars on amazon.comOn Intelligence


Jonathan Hawkins’s concern in “On Intelligence” is to outline a theory of what intelligence is that differs from ones floated around in various artificial intelligence (AI) circles. First, most theories of how to build “intelligent machines” focus exclusively on “intelligent behavior” without focus on the “thought” that must be behind it. (Think about Alan Turing’s test of an intelligent machine: if its behavior seems intelligent to humans, it must be intelligent. Purely behavioral.) Also, Hawkins is concerned that those few AI folks who have given thought to what intelligence is, apart from behavior, see intelligence as “ability to computer” and analogize it to a computer. But, Hawkins rightly notes, what we see as human intelligence -ability to synthesize disparate information, create novel solutions, apply old knowledge to new problems – is much more than computation.
