The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproductio… - Lewis Mumford

If, as many anthropologists still hold, the making and using of tools as one of the chief sources of primitive man's intellectual development, is it not time that we asked ourselves what will happen to man if he departs as completely as he now threatens to do from his primal polytechnic occupations? Since they can no longer be pursued at a profit, perhaps they will have to be restored as modes of sport and recreation, even more as helpful — increasingly essential — forms of personal service and mutual aid.

(The processes are) doubly ruinous: they impoverish the earth by hastily removing, for the benefit of a few generations, the common resources which, once expended and dissipated, can never be restored; and second, in its technique, its habits, its processes, the paleotechnic period is equally inimical to the earth considered as a human habitat, by its destruction of the beauty of the landscape, its ruining of streams, its pollution of drinking water, its filling the air with a finely divided carboniferous deposit, which chokes both life and vegetation.

In his discussion on slavery Aristotle said that when the shuttle wove by itself and the plectrum played by itself chief workmen would not need helpers nor masters slaves. At the time he wrote, he believed that he was establishing the eternal validity of slavery; but for us today he was in reality justifying the existence of the machine. Work, it is true, is the constant form of man's interaction with his environment, if by work one means the sum total of exertions necessary to maintain life; and the lack of work usually means an impairment of function and a breakdown in organic relationship that leads to substitute forms of work, such as invalidism and neurosis. But work in the form of unwilling drudgery or of that sedentary routine which... the Athenians so properly despised—work in these forms is the true province of machines. Instead of reducing human beings to work-mechanisms, we can now transfer the main part of burden to automatic machines. This potentially... is perhaps the largest justification of the mechanical developments of the last thousand years.
