320 LAW AND FREEDOM IN HISTORY Denique si vocem Rerum Natura repente mittat et hoc alicui nostrum sic increpet ipsa 'quid tibi tanto operest, mortalis, quod nimis aegris luctibus indulges ? quid mortem congemis ac fles ? . . .' iure, ut opinor, agat, iure increpet inciletque. cedit enim rerum noyitate extrusa vetustas semper, et ex aliis aliud reparare necessest . . . materies opus est ut crescant postera saecla, quae tamen omnia te vita perfuncta sequentur; nee minus ergo ante haec quam tu cecidere, cadentque. sic alid ex alio numquam desistet oriri, vitaque mancipio nulli datur, omnibus usu.1 The ordeal of Death, which was so tragic a catastrophe for each indi- vidual living creature, was evidently an indispensable contrivance for an ambitious Natura Creatrix if she was ever to break out of the blind alley of a deathless and therefore static unicellular organism into the infinite variety of multicellular organic life. Nature's endowment of her new creation with the gift of multiplicity-in-unity at the price of mortality insured her against being committed to more than a limited liability towards any single specimen or single species of her brood. It gave her a perpetually recurrent opportunity to liquidate her proven miscarriages and to follow up her more promising experiments. In fact, the epiphany of Death in the history of Life on Earth, so far from convicting Nature of ineptitude or impotence, was evidence that she had been successful in retaining an initiative that was a synonym for creativity itself; for the mortality of the creature was merely the obverse of Nature's unforfeited freedom to carry on her work of creation by varying at will the ratio between racial change and racial stability in the ever flowing series of her offspring. If this 'concede: necessest'2 were the whole story of Death's role in Nature's dealings with her creature Man, we might have ruefully to con- clude that, in the working of the Generation Cycle, a rhythm in the flow of Physical Life had in truth imposed its dominion on the Spirit of Man. Before we accept this conclusion, however, we may recall that, in the life of those higher living creatures, culminating in Man, which pro- create and die, there are two alternative methods of transmitting, from one generation to another, behaviour approved as valuable for future representatives of the species. There can be a transmission of a racial heritage of instincts and aptitudes through the physiological process of procreation; and there can be a transmission of a social heritage of habits and knowledge through the spiritual process of moral and intellectual education in the broad unprofessional meaning of this word.3 The second of these methods of transmission, which was the younger of the two, had been employed, as a second string to the older physiological device, by i Lucretius, De Rerum Naturd, Book III, II. 931-4, 963-5, and 967-71. z Lucretius, op. cit., Book III, 1. 962. s 'Just as biological evolution was rendered both possible and inevitable when material organisation became self-reproducing, so conscious evolution was rendered both possible and inevitable when social organisation became self-reproducing* (Huxley, Julian: Evolutionary Ethics, the Romanes Lecture 1943, reprinted in Huxley, T.
