Intelligence In The Ancient World
The other night on the History Channel I saw a fascinating program about Heron of Alexandria which showed that modern humans are no more intelligent now than some people were two millenia in the past. The major difference is technological media, not intelligence.
Born circa 75 A.D., Heron was a Greco-Roman engineer and mathematician who:
(1)Invented a steam engine 1,700 years before the Industrial Revolution. If it had been put to use, steam chariots and even railroads might have criss-crossed the Roman Empire.
(2)Developed a stage theater with audio and visual special effects. One effect was sets that automatically moved on and off stage in synch with the unfolding plot of the play. The motion was generated by using the force of gravity.
(3)Invented a mechanical program that worked like a computer software program. It used ropes wound around a spindle, pulleys, strategically placed pegs and gravity. If the media had been electricity and integrated circuits instead of gravity and natural materials, Heron would have become the Bill Gates of his era.
(4)Designed war machines that gave the Roman Legions a distinct advantage in battle. (Heron's one fault -- he was a "defense" contractor.)
The best minds of today are no sharper than the intellectual elite of the ancient world. Human intelligence has NOT evolved to a higher level. We have simply become more specialized in an increasingly complex division of labor. As Henry David Thoreau observed: "We live like ants, though the fable tells us we were changed into men long ago."
