Wigner wrote (Nov. 18, 1978) ... " ... as far as living organism of any complexity are concerned, the same initial state hardly can be realized several times. There are no two identical people and if we repeat the same experiment on the same individual the initial conditions are no longer the same - the individual will remember at the second experiment the event of the first one - his mental outlook will have changed thereby. This means that the relevant statements of the theory encompassing life will be terribly different from those of the present natural sciences." and also ... "I do not believe there are two entities: body and soul. I believe that life and consciousness are phenomena which have a varying effect on the event around us - just as light pressure does. Under many circumstances, those with which present-day physics is concerned, the phenomenon of life has an entirely negligible influence. There is then a continuous transition to phenomena, such as our own activities, in which this phenomenon has a decisive influence. Probably, the behaviour of viruses and bacteria could be described with a high accuracy with present theories. Those of insects could be described with a moderate approximation, those of mammals and men are decisively influenced by their minds. For these, present physical theory would give a false picture even as far as their physical behavior is concerned." E. P. Wigner, Philosophical Reflections and Syntheses, Springer, 1995, page 272
