Note 142 — Chapter VII · The Machine Industry

On the other hand the aphorism often cited, that “Necessity is the Mother of Invention,” appears to be nothing better than a fragment of uncritical rationalism. It offers a rationalised, ex post facto account of changes that take place, and reflects that ancient preconception by help of which the spokesmen of edification were enabled to interpret all change as an improvement due to the achievement of some definitely foreknown end. It appears also to be consistently untrue, except so far as “invention” is to be taken as a euphemistic synonym for “prevarication.” Doubtless, the felt need of ways and means has brought on many changes in technology, but doubtless also the ulterior consequences of any one of the greater mechanical inventions have in the main been neither foreseen nor intended in the designing of them. The more serious consequences, especially such as have an institutional bearing, have been enforced by the inventions rather than designed by the inventors.
