Sounds as though there is an axe to grind here, but I personally side with Jamison and do not consider mad genius to be a myth. To think well beyond the herd, acquired knowledge must be altered at the synaptic level. The problem is that societal norms and acceptable behaviors, stored collectively within those same synapses, will similarly drift. So, expect the significant paradigm shifts to come from the more 'twisted' minds, as the ancients accurately observed.
