Something overlooked by Hans Hass [in The Human Animal] is the absence of biological or psychological means of coping with the effects of our own technical ingenuity in creating new organs. The problem is clearly indicated by Albert Simeons in Man’s Presumptuous Brain, in which he says that ”when about a half million years ago, when man began slowly to embark upon the road to cultural advance, an entirely new situation arose. The use of instruments and the control of fire introduced artifacts in which the cortex could avail itself for purposes of living. These artifacts had no relationship whatever to the organization of the body and could, therefore, not be integrated into the functioning of the brain-stem.”

….. What Simeons is saying is that our natural responses to media and to technology are irrelevant, that we cannot trust our instincts or our natural physical responses to new things. They will destroy us. How are we to bypass or offset merely physical response to new technology and new environments created by new technologies?
