So much for savage stories of the origin of death. They all imply a belief that death is not a necessary part of the order of nature, but that it originated in a pure mistake or misdeed of some sort on somebody's part, and that we should all have lived happy and immortal if it had not been for that disastrous blunder or crime. Thus the tales reflect the same frame of mind which I illustrated in the last lecture, when I shewed that many savages still to this day believe all men to be naturally immortal and death to be nothing but an effect of sorcery. In short, whether we regard the savage's attitude to death at the present day or his ideas as to its origin in the remote past, we must conclude that primitive man cannot reconcile himself to the notion of death as a natural and necessary event; he persists in regarding it as an accidental and unnecessary disturbance of the proper order of nature. To a certain extent, perhaps, in these crude speculations he has anticipated certain views of modern biology. Thus it has been maintained by Professor August Weissmann that death is not a natural necessity, that many of the lowest species of living animals do in fact live for ever; and that in the higher animals the custom of dying has been introduced in the course of evolution for the purpose of thinning the population and preventing the degeneration of the species, which would otherwise follow through the gradual and necessary deterioration of the immortal individuals, who, though they could not die, might yet sustain much bodily damage through hard knocks in the hurly-burly of eternal existence on earth.
Weissmann's view that death is not a natural necessity but an adaptation acquired in the course of evolution for the advantage of the race.
On this subject I will quote some sentences from Professor Weissmann's essay on the duration of life. He says, "The necessity of death has been hitherto explained as due to causes which are inherent in organic nature, and not to the fact that it may be advantageous. I do not however believe in the validity of this explanation; I consider that death is not a primary necessity, but that it has been secondarily acquired as an adaptation. I believe that life is endowed with a fixed duration, not because it is contrary to its nature to be unlimited, but because the unlimited existence of individuals would be a luxury without any corresponding advantage. The above-mentioned hypothesis upon the origin and necessity of death leads me to believe that the organism did not finally cease to renew the worn-out cell material because the nature of the cells did not permit them to multiply indefinitely, but because the power of multiplying indefinitely was lost when it ceased to be of use.... John Hunter, supported by his experiments on anabiosis, hoped to prolong the life of man indefinitely by alternate freezing and thawing; and the Veronese Colonel Aless. Guaguino made his contemporaries believe that a race of men existed in Russia, of which the individuals died regularly every year on the 27th of November, and returned to life on the 24th of the following April. There cannot however be the least doubt, that the higher organisms, as they are now constructed, contain within themselves the germs of death. The question however arises as to how this has come to pass; and I reply that death is to be looked upon as an occurrence which is advantageous to the species as a concession to the outer conditions of life, and not as an absolute necessity, essentially inherent in life itself. Death, that is the end of life, is by no means, as is usually assumed, an attribute of all organisms. An immense number of low organisms do not die, although they are easily destroyed, being killed by heat, poisons, etc. As long, however, as those conditions which are necessary for their life are fulfilled, they continue to live, and they thus carry the potentiality of unending life in themselves. I am speaking not only of the Amoebae and the low unicellular Algae, but also of far more highly organized unicellular animals, such as the Infusoria."[106]
Similar view expressed by Alfred Russel Wallace.
A similar suggestion that death is not a natural necessity but an innovation introduced for the good of the breed, has been made by our eminent English biologist, Mr. Alfred Russel Wallace. He says: "If individuals did not die they would soon multiply inordinately and would interfere with each other's healthy existence. Food would become scarce, and hence the larger individuals would probably decompose or diminish in size. The deficiency of nourishment would lead to parts of the organism not being renewed; they would become fixed, and liable to more or less slow decomposition as dead parts within a living body. The smaller organisms would have a better chance of finding food, the larger ones less chance. That one which gave off several small portions to form each a new organism would have a better chance of leaving descendants like itself than one which divided equally or gave off a large part of itself. Hence it would happen that those which gave off very small portions would probably soon after cease to maintain their own existence while they would leave a numerous offspring. This state of things would be in any case for the advantage of the race, and would therefore, by natural selection, soon become established as the regular course of things, and thus we have the origin of old age, decay, and death; for it is evident that when one or more individuals have provided a sufficient number of successors they themselves, as consumers of nourishment in a constantly increasing degree, are an injury to their successors. Natural selection therefore weeds them out, and in many cases favours such races as die almost immediately after they have left successors. Many moths and other insects are in this condition, living only to propagate their kind and then immediately dying, some not even taking any food in the perfect and reproductive state."[107]
Savages and some men of science agree that death is not a natural necessity.
Thus it appears that two of the most eminent biologists of our time agree with savages in thinking that death is by no means a natural necessity for all living beings. They only differ from savages in this, that whereas savages look upon death as the result of a deplorable accident, our men of science regard it as a beneficent reform instituted by nature as a means of adjusting the numbers of living beings to the quantity of the food supply, and so tending to the improvement and therefore on the whole to the happiness of the species.
