Only when love takes the lead will the earth, and life on earth, be safe again. And not until then. - Lewis Mumford

Galileo's mechanical world was only a partial representation of a finite number of probable worlds, each peculiar to a particular living species; and all these worlds are but a portion of the infinite number of possible worlds that may have once existed or may yet exist. But anything like a single world, common to all species, at all times, under all circumstances, is a purely hypothetical construction, drawn by inference from pathetically insufficient data, prized for the assurance of stability and intelligibility it gives, even though that assurance turns out, under severe examination, to be just another illusion. A butterfly or a beetle, a fish or a fowl, a dog or a dolphin, would have a different report to give even about primary qualities, for each lives in a world conditioned by the needs and environmental opportunities open to his species. In the gray visual world of the dog, smells, near and distant, subtle or violently exciting, probably play the part that colors do in man's world-though in the primal occupation of eating, the dog's world and man's world would approach each other more closely.

Unfortunately, once an economy is geared to expansion, the means rapidly turn into an end and "the going becomes the goal." Even more unfortunately, the industries that are favored by such expansion must, to maintain their output, be devoted to goods that are readily consumable either by their nature, or because they are so shoddily fabricated that they must soon be replaced. By fashion and built-in obsolescence the economies of machine production, instead of producing leisure and durable wealth, are duly cancelled out by the mandatory consumption on an even larger scale.

In the elemental emotions of fear and rage associated with the most primitive parts of the brain, this swift response without conscious intervention or direction is a condition of survival: but something more than survival comes forth from it; for this very automatism freed the growing brain and ramifying nervous system for more important services, detached from the immediate pressure for survival, performed by the new brain. Here by his conscious symbolic activities man created a second realm that conforms more closely to his higher personal and social needs.
