Behind the Mirror

Behind the Mirror: A Search for a Natural History of Human Knowledge is a 1973 book by the ethologist Konrad Lorenz. Lorenz shows the essentials of a lifetime's work and summarizes it into his very own philosophy: evolution is the process of growing perception of the outer world by living nature itself. Stepping from simple to higher organized organisms he shows how they benefit from information processing. The methods mirrored by organs have been created in the course of evolution as the natural history of this organism. Lorenz uses the mirror as a simplified model of our brain reflecting the part of information from the outside world it is able to "see". The backside of the mirror was created by evolution to gather as much information as needed to better survive. The book gives a hypothesis how consciousness was "invented" by evolution.
