The concept of radical novelties is of contemporary significance because, while we are ill-prepared to cope with them, science and technology have now shown themselves expert at inflicting them upon us. Earlier scientific examples are the theory of relativity and quantum mechanics; later technological examples are the atom bomb and the pill. For decades, the former two gave rise to a torrent of religious, philosophical, or otherwise quasi-scientific tracts. We can daily observe the profound inadequacy with which the latter two are approached, be it by our statesmen and religious leaders or by the public at large. So much for the damage done to our peace of mind by radical novelties.

I raised all this because of my contention that automatic computers represent a radical novelty and that only by identifying them as such can we identify all the nonsense, the misconceptions and the mythology that surround them. Closer inspection will reveal that it is even worse, viz. that automatic computers embody not only one radical novelty but two of them.
