CHAPTER IV
The Country that is Not Ours
The last two chapters have served to show the impasse into which human perception and thinking have come - in so far as they have been used for scientific purposes - by virtue of the relationship to the world in which man's consciousness found itself when it awoke to itself at the beginning of modern times. Now although the onlooker in man, especially in the earliest stage of our period, gave itself up to the conviction that a self-contained picture of the universe could be formed out of the kind of materials available to it, it nevertheless had a dim inkling that this picture, because it lacked all dynamic content, had no bearing on the real nature of the universe. Unable to find this reality within himself, the world-onlooker set about searching in his own way for what was missing, and turned to the perceptible world outside man. Here he came, all unexpectedly, upon ... electricity. Scarcely was electricity discovered than it drew human scientific thinking irresistibly into its own realm. Thereby man found himself, with a consciousness completely blind to dynamics, within a sphere of only too real dynamic forces. The following description will show what results this has had for man and his civilization.
*
First, let us recall how potent a role electricity has come to play in social life through the great discoveries which began at the end of the eighteenth century. To do this we need only compare the present relationship between production and consumption in the economic sphere with what it was before the power-machine, and especially the electrically driven machine, had been invented. Consider some major public undertaking in former times - say the construction of a great mediaeval cathedral. Almost all the work was done by human beings, with some help, of course, from domesticated animals. Under these circumstances the entire source of productive power lay in the will-energies of living beings, whose bodies had to be supplied with food, clothing and housing; and to provide these, other productive powers of a similar kind were required near the same place. Accordingly, since each of the power units employed in the work was simultaneously both producer and consumer, a certain natural limit was placed on the accumulation of productive forces in any one locality.
This condition of natural balance between production and consumption was profoundly disturbed by the introduction of the steam engine; but even so there were still some limits, though of a quite different kind, to local concentrations of productive power. For steam engines require water and coal at the scene of action, and these take up space and need continual shifting and replenishing. Owing to the very nature of physical matter, it cannot be heaped up where it is required in unlimited quantities.
All this changed directly man succeeded in producing energy electro-magnetically by the mere rotation of material masses, and in using the water-power of the earth - itself ultimately derived from the cosmic energies of the sun - for driving his dynamos. Not only is the source of energy thus tapped practically inexhaustible, but the machines produce it without consuming on their own account, apart from wear and tear, and so make possible the almost limitless accumulation of power in one place. For electricity is distinguished from all other power-supplying natural forces, living or otherwise, precisely in this, that it can be concentrated spatially with the aid of a physical carrier whose material bulk is insignificant compared with the energy supplied.
Through this property of electricity it has been possible for man to extend the range of his activity in all directions, far and near. So the balance between production and consumption, which in previous ages was more or less adequately maintained by natural conditions, has been entirely destroyed, and a major social-economic problem created.
