The Edinburgh Lectures on Mental Science
written by "Troward, T. (Thomas), 1847-1916"
...ndescent nebula dispersed over vast infinitudes of space; later this condenses into a central sun surrounded by a family of glowing planets hardly yet consolidated from the plastic primordial matter; then succeed untold millenniums of slow geological formation; an earth peopled by the lowest forms of life, whether vegetable or animal; from which crude beginnings a majestic, unceasing, unhurried, forward movement brings things stage by stage to the condition in which we know them now. Looking at this steady progression it is clear that, however we may conceive the nature of the evolutionary principle, it unerringly provides for the continual advance of the race. But it does this by creating such numbers of each kind that, after allowing a wide margin for all possible accidents to individuals, the race shall still continue:-- "So careful of the type it seems So careless of the single life." In short, we may say that the cosmic intelligence works by a Law of Averages which allows a wide margin of accident and failure to the individual. But the progress towards higher intelligence is always in the direction of narrowing down this margin of accident and taking the individual more and more out of the law of averages, and substituting the law of individual selection. In ordinary scientific language this is the survival of the fittest. The reproduction of fish is on a scale that would choke the sea with them if every individual survived; but the margin of destruction is correspondingly enormous, and thus the law of averages simply keeps up the normal proportion of the race. But at the other end of the scale, reproduction is by no means thus enormously in excess of survival. True, there is ample margin of accident and disease cutting off numbers of human beings before they have gone through the average duration of life, but still it is on a very different scale from the premature destruction of hundreds of thousands as against the surv...
