What Is Life?: With Mind and Matter and Autobiographical Sketches - Erwin Schrödinger,Roger Penrose

"Only one conciousness per mind." (NOT brain.) Possibly tautological; "Only one mind per mind." Possibly wrong; IIRC one theory of "voices" in schizophrenia is intrusion of normally subconcious sub-personalities into the main personality i.e. you're actually hearing someone else's thoughts!

 

A frequently quoted book, "Man on his Nature", Sherrington looks more valuable than this essay...because properly scientific.

Why should brains generate conciousness when they are made of the stuff as everything else? No answers - just a description of the problem. A not very clear one...

Has human evolution ceased? Medical argument that it has; behavioural argument that it hasn't; now thoroughly out-of-date discussion of Lamarkism.

 

The medical argument seems wrong to me; it's only been valid (generously) ~200yrs. We face the complete failure of antibiotics and an impending Malthusian population crash with attendant resource wars in the near future. Hence the timescale is way too short to say evolution of the species has permanently ended. Meanwhile stone-age Amazonian tribes remain oblivious to modern technological survival advantages and exposed to many selection pressures, anyway.

Mind and Matter: A tacit assumption that nothing supernatural is going on. Brief argument that conciousness is associated with nervous systems, followed by an argument that conciousness is associated with learning - it is at least implied idea that we conciously learn everything that the brain does - this must surely be wrong? How could crucial autonomic functions be conciously learned by a foetus? But the model of concious learning seems right and a more detailed version is widely used in learning theory.

The final chapter of What is Life? is on the "mind-body" problem. It rapidly descends into religio-metaphysical gibberish. This bodes ill for the next part of the book, Mind and Matter - I fear it will be ~70p of the same incomprehensible nonsense.
