Comprehensive Look At Pain. This book is a seemingly comprehensive look at pain, what it is, how humans handle it, and why it is in at least some cases necessary for our development. What it is *not* is well documented, having only a scant few page “selected works” section to document its various claims – far short of the more routine 25% ish bibliography section of many science books. It is also *not* a biological-exclusive look at the issue, instead covering all aspects from the biological to the psychological to at times even the metaphysical. Still, for anyone interested in the subject it is a worthy read, and a very approachable read to boot. Very much recommended.
