" "So the claim that, just as children are not developmentally ready for certain concepts in mathematics or logic, so 'primitive' peoples are not intellectually able to grasp science and technology, is nonsense. This vestige of colonialism and racism is belied by the everyday activities of people living with no fixed abode and almost no possessions, the few remaining hunter-gatherers - the custodians of our deep past.
Of Cromer's criteria for 'objective thinking', we can certainly find in hunter-gatherer peoples vigorous and substantive debate, direct participatory democracy, wide-ranging travel, no priests, and the persistence of these factors not for 1,000 but for 300,000 years or more. By his criteria hunter-gatherers ought to have science. I think they do. Or did.
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

President Ronald Reagan, who spent World War II in Hollywood, vividly described his own role in liberating Nazi concentration camp victims. Living in the film world, he apparently confused a movie he had seen with a reality he had not. On many occasions in his Presidential campaigns, Mr. Reagan told an epic story of World War II courage and sacrifice, an inspiration for all of us. Only it never happened; it was the plot of the movie A Wing and a Prayer — that made quite an impression on me, too, when I saw it at age 9. Many other instances of this sort can be found in Reagan's public statements. It is not hard to imagine serious public dangers emerging out of instances in which political, military, scientific or religious leaders are unable to distinguish fact from vivid fiction.

Whenever our ethnic or national prejudices are aroused, in times of scarcity, during challenges to national self-esteem or nerve, when we agonize about our diminished cosmic place and purpose, or when fanaticism is bubbling up around us — then, habits of thought familiar from ages past reach for the controls. The candle flame gutters. Its little pool of light trembles. Darkness gathers. The demons begin to stir.
