Since the late-nineteenth century, it has been understood that living creatures derive their characteristics from tiny cells called genes, which are contained in the male sperm and the female egg. The colour of my hair and eyes, and the size of my feet, are all determined by genes. But no one was sure how the genes did this. In the mid-1950s, it gradually became clear that the genes are like a computer card with holes punched in it. The 'holes' are actually molecules of a substance called DNA, linked together in the form of a double spiral, something like two springs twisted together in opposite directions.
The more we know about this computer system that makes us what we are, the more baffling it becomes. Darwin's heory of evolution accounts for the giraffe's neck and the elephant's trunk in terms of accident, just as you might explain a rock worn into the shape of a face by pointing to the wind and rain. Science hates 'teleology,' the notion of purpose. The rock didn't want to be sculpted into the shape of a face, and the wind and rain didn't want to sculpt it; it just happened. Similarly, biologists hate the heresy known as 'vitalism,' the notion that life somehow 'wants' to produce healthier and more intelligent creatures; they just happen to get produced because health and intelligence survive better than sickness and stupidity. But when one realises that human beings are produced by a highly complex computer card, it becomes difficult to avoid slipping into 'teleology' and wondering who programmed the computer.
In 1969, a cybernetician, Dr. David Foster, lectured to the International Conference on Cybernetics at the Imperial College, London, and sketched some of the philosophical implications of these discoveries. He pointed out that from the cybernetician's point of view, it is possible to consider the universe in terms of data and data processing. An acorn, for example, may be regarded as the 'programme' for an oak tree. Even an atom can be thought of as a computer card with three holes punched in it, the holes being (a) the number of particles in the nucleus, (b) the number of electrons orbiting round it, (c) the energy of these electrons expressed in terms of the smallest known 'parcel' of energy, Planck's constant. Dr. Foster goes on: 'Surely it must be obvious that the essential nature of matter is that the atoms are the alphabet of the universe, that chemical compounds are words, and that DNA is rather a long sentence or even a whole book trying to say something such as "elephant," "giraffe" or even "man."'
He goes on to point out that the basic building brick of any electrical information theory is one electrical wave, and a wave consists of two halves, because it is measured from the top of one 'bump' to the bottom of the next trough:
That is, a wave is a 'binary' system, and computers work upon binary mathematics. This is an important step in his argument, for if we think of 'waves' as the basic vocabulary of the universe, then you can think of life – in fact, of all matter – as being due to waves that have somehow been cybernetically programmed.
What he is saying certainly sounds like 'teleology.' If I saw a complex chemical process being regulated and controlled by a computer, I would infer that someone had programmed the computer. Dr. Foster is saying that, to the eyes of a cybernetician, the complex structures of life around him reveal data processing on a massive scale. This is a matter of scientific fact. And he naturally finds himself wondering what intelligence processed the data?
And now Dr. Foster takes his most controversial step. He explains that 'as an automation consultant, whenever I design a control system for a process it is axiomatic that the speed of the control system must be greater than that of the motions of the process concerned.' For example, you can drive your car because you can think faster than the engine works; if you couldn't, you would crash. But in that case, programming of matter must be achieved by vibrations – or waves – much faster than the vibrations of matter. That is, in cosmic radiations. The universe is, of course, full of cosmic radiations; and, in Dr. Foster's view, these are probably what lie behind the 'programming' of the DNA molecules.
