We arrest our inner creativity with external compulsions and irrelevant anxieties, at the mercy of constant interruptions by telephone and radio and … - Lewis Mumford

What was happily proved by this early revolution is something that we perhaps need to be reminded of again today: that neither exact science nor engineering is proof against the irrationality of those that operate the system. Above all, that the strongest and most efficient of megamachines can be overthrown, that human errors are not immortal. The collapse of the Pyramid Age proved that the megamachine exists on a basis of human beliefs, which may crumble, of human decisions, which may prove fallible, and human consent, which, when the magic becomes discredited, may be withheld. The human parts that composed the megamachine were by nature mechanically imperfect: never wholly reliable. Until real machines of wood and metal could be manufactured in sufficient quantity to take the place of most of the human components, the megamachine would remain vulnerable.

Material artifacts may stubbornly defy time, but what they tell about man's history is a good deal less than the truth, the whole truth, and nothing but the truth. If the only clue to Shakespeare's achievement as a dramatist were his cradle, an Elizabethan mug, his lower jaw, and a few rotted planks from the Globe Theatre, one could not even dimly imagine the subject matter of his plays, still less guess in one's wildest moments what a poet he was. Though we would still be far from justly appreciating Shakespeare, we should nevertheless have a better notion of his work through examining the known plays of Shaw and Yeats and reading backward.

But we must not overlook the vital connection between all physical movement and the acquisition of speech, for this has now been established independently by psychologists. In the case of children whose speech has been retarded or has become disordered, they have found that the child's ability to handle words can be recovered by re-training his motor behavior through inducing him to resume the earlier posture of crawling, the stage that usually accompanies, or slightly precedes, the first efforts at speech.
