I was told many years ago that man is an electrical, chemical, mechanical machine that cannot think or reason....that has no free will...that individuality is a myth. The underlying process regarding all the reasons for human behavior is not at all the argument for the genetic reference but it is for the environment and it's influence. This "neuro-scientist" is only correct in her assumptions that the human brain, or any other brain, is manipulable but only to the degree that the information in it is manipulable. She is obviously silly to assume that there is such a concept as right and wrong, good or bad, up or down or any other two-valued determination. Aside from any physical malfunction the only mental illness is Ignorance.
