This is an exceptionally good book with lively, intelligent writing. The author examines past information with wit, presenting what remains most significant, in view of the fascinating aspects of current international research on the senses. There are keen analyses of how the five main senses function, as well as the less often recognized heat sense, time sense, and ESP. One section contains the most readable introduction to bionics we have seen. The text throughout is laced with perceptive anecdotes.
