The autist’s greatest strength–and weakness–is his deficiency in the neural mechanisms of mimicry. Without the necessary feedback loops, he fails to subconsciously adopt of his peers’ words, actions, and beliefs, leaving him is free to develop his own–caring little about how strange they seem to everyone else.
At his most unfortunate, the infant autist lacks even the instincts necessary to imitate the mouth-shapes and mouth-sounds of his parents, leaving him unable to develop speech. Some of these autists understand speech perfectly well, but simply cannot produce it.
At his most fortunate, the autist, immune to other people’s preconceived notions, revolutionizes some field of science or math–or both:
Here is buried Isaac Newton, Knight, who by a strength of mind almost divine, and mathematical principles peculiarly his own, explored the course and figures of the planets, the paths of comets, the tides of the sea, the dissimilarities in rays of light, and, what no other scholar has previously imagined, the properties of the colours thus produced. Diligent, sagacious and faithful, in his expositions of nature, antiquity and the holy Scriptures, he vindicated by his philosophy the majesty of God mighty and good, and expressed the simplicity of the Gospel in his manners. Mortals rejoice that there has existed such and so great an ornament of the human race! He was born on 25 December 1642, and died on 20 March 1726/7.—Translation from G.L. Smyth, The Monuments and Genii of St. Paul’s Cathedral, and of Westminster Abbey (1826), ii, 703–4.
