The insights given to us by individuals of great intelligence can harm society. We have difficulty in dealing with the pace of scientific and technological developments. The brains of those like Einstein, Newton and Darwin spawn those developments. (I agree)
The decisions on handling them are made by men and women "lesser"(should read MORE) in intelligence and (NO) understanding. They simply cannot deal adequately with the physical and biological forces unleashed.
We are trying to cope with nuclear proliferation and the accompanying threat of destruction, environmental changes wrought by technology, advances in medical technology and manipulation using sophisticated psychological techniques. We are failing.
The forces unleashed by the "intelligence"(should read:Contact with higher knowledge) of Einstein, Newton and Darwin are destroying us because we cannot handle them. Would we better off if those outstanding individuals had not existed.
Intelligence: Is to make use of 'knowledge' for the benefit of etc.
Royal Raymond Rife for example was such a person who put knowledge into practice for the benefit of the human race.
