El Panoptico
This is an important book dealing with a plan to keep prisoners or inmates of a mental institution under constant supervision by only one person. The method uses a central tower where a supervisor can see out in all directions but inmates cannot see in. This book was used by Michael Ignatieff in his book 'A Just Measure of Pain'.
Unfortunately original copies in English cost over $10,000.00 USD.
An English reprint is out of print, so this Spanish version is an alternative if one speaks Spanish. Not an ideal solution but the best available at the present. It is fervently to be hoped that the English reprint will become available in the future.
