Let us glance briefly at the problems from another angle. The power developed in the combustion of one pound of coal is theoretically equal to 11,580,000 foot pounds. But by our imperfect methods of utilization, not more than 1,500,000 foot pounds are made available. This is about the amount of physical power exerted by a man of ordinary strength during a day’s work. Hence 300 pounds of coal will represent the labor of a man for a year. The current production of coal in the world is about 500,000,000 tons (1906). If we suppose that only half of this coal goes for mechanical use, this will give us approximately the number as 1,600,000,000 man-powers that are producers but not consumers. Let us take a still broader view of resources; we have approximately 1,600,000,000 living human beings (all censuses available between 1902 and 1906); a wealth of approximately $357,000,000,000 (_Social Progress_, 1906, page 221) which in our analysis is dead men’s work; and sun-power equal, in work, to the work of our whole living population, or equal to 1,600,000,000 sun man-powers. Taking, for simplicity’s sake, $35.70 as the average living expenses per annum for each one of the _world’s_ population, we will have: (1) 1,600,000,000 living men. (2) 10,000,000,000 living man-powers of the dead. (3) 1,600,000,000 sun man-powers. Such classification needs a reflection: man is intrinsically an increasing exponential power and always produces two use-values—the potential and the kinetic. All living men have in some degree this type of power; _they are able to direct and use basic powers_. So we see that this world is really populated to-day by three different populations, all of them dynamic and active: to wit, 1,600,000,000 living men; 10,000,000,000 living man-powers of the dead; 1,600,000,000 sun man-powers. Thus it is obvious beyond any argument, _that this additional producing but not consuming_ population, has been produced mainly by the work of all our past generations. It is said “mainly” because, if we were the first generation, we would be just aboriginal savages having nothing and progressing very slowly. The reason why we progress very rapidly, in this stage of civilization, is explained very clearly by the mathematical law of a geometrical progression, with an ever increasing number of terms, the magnitude of the terms increasing more rapidly all the time.(11) This fact is the reason why the old unscientific and artificial social system requires and must undergo profound transformation. Human progress, in many directions, is so far advanced that social institutions can not much longer continue to lag so far behind. Static ethics, static jurisprudence, static economics, and the rest must become dynamic; if they do not continue to progress peacefully in accordance with the law of the progress of science, they will be forced by violent readjustments, recurring with ever increasing frequency.
