Development of Man Estimated duration of the Cainozoic Period, assuming that the thickness of the deposits is about 63,000 feet, and that deposits accumulate at the rate of 1 foot in 100 years. Drawn to the scale of 1 mm. to 100,000 years. The estimate is given and explained by Prof. Sollas in the Quarterly Journal of the Geological Society, LXV. (1909). The “tree” is based on that given by Dr. A. Keith in The Antiquity of Man, p. 509. If we suppose the differentiation of the HominidÆ to have begun before the close of the Oligocene, about (say) 3,500,000 years are allowed for the evolution of the existing species of Man. All these reckonings are provisional. Prof. MacBride, in his popular introduction to Zoology (p. 84), also traces the specialisation of Man to the hunting life. My friend Mr. Thomas Whittaker has sent me the following extract from Comte’s Politique Positive, I. pp. 604-5: “L’obligation de se nourrir d’une proie qu’il faut atteindre et vaincre, perfectionne À la fois tous les attributs animaux, tant intÉrieurs qu’extÉrieurs. Son influence envers les sens et les muscles est trop Évidente pour exiger ici aucun examen. Par sa rÉaction habituelle sur les plus hautes fonctions du cerveau, elle dÉveloppe Également l’intelligence et l’activitÉ, dont le premier essor lui est toujours dÛ, mÊme chez notre espÈce. A tous ces tÎtres, cette nÉcessitÉ modifie aussi les races qui en sont victimes, d’aprÈs les efforts moins Énergiques, mais plus continus, qu’elle y provoque pour leur dÉfense. Dans les deux cas, et surtout quant À l’attaque, elle dÉtermine mÊme les prÉmiÈres habitudes de co-opÉration active, au moins temporaire. BornÉes À la simple famille chez les espÈces insociables, ces ligues peuvent ailleurs embrasser quelquefois de nombreuses troupes. Ainsi commencent, parmi les animaux, des impulsions et des aptitudes qui ne pouvaient se dÉvelopper que d’aprÈs la continuitÉ propre À la race la plus sociable et la plus intelligente. Enfin, la condition carnassiÈre doit aussi Être appreciÉe dans sa rÉaction organique. Une plus forte excitation, une digestion moins laborieuse et plus rapide, une assimilation plus complÈte produisant un sang plus stimulant: telles sont ses propriÉtÉs physiologiques. Toutes concourent À dÉvelopper les fonctions supÉrieures, soit en augmentant l’Énergie de leurs organes, soit en procurant plus de temps pour leur exercice.” Nothing incredible in this—nor of wolves. Can the vixen provide for herself and litter alone? If not, the dog must do it: else there could be no foxes or wolves. However, de Canteleu denies that the he-wolf takes any part in rearing the young (La Chasse du Loup, p. 30). For further illustrations of the influence of coincidences in establishing a belief in Magic, see ch. viii. § 5. For this reason (I suppose) the belief is not exploited by wizards, who have no use for innocent superstition, and it remains pure folklore. There may not be any connexion between this animistic doctrine of human souls possessing animals and the magical doctrine of shape-changing. If they are connected, it is easy to see that in a certain atmosphere of popular philosophy, if shape-changing were believed in, the possession theory might be accepted as the true explanation upon merely being proposed. Indeed, it would make intelligible such a case as this: a man’s leopard is seen on the skirts of the village; but he himself is known to be in his hut. Animistic explanation does not always follow culture: Europe adheres to shape-changing. Yet in the Volsung Saga the superstition is already degenerate: Sigmund and his son change into wolves by putting on wolf-skins belonging to two were-wolves whom they find asleep. This is a rationalisation—disguise as a step toward change. An earlier step is to say a man who would change must put on a belt of wolf-skin. Transcriber’s note Footnotes were renumbered and moved to the end of this this book. An alphabetic jump table was added to the index. Pagenumbers in the index with a “n.” after it, link directly to the footnote originally on that page. Links might not work in some reading devices. Some minor corrections were made without note, such as missing punctuation and missing page numbers in the index. Also the following corrections were made, on page Otherwise the original was preserved, including inconsistent spelling, hyphenation, capitalization, and possible errors in foreign words. Additional: The names of some of the quoted authors were spelled inconsistently in the original, for example Codrington was spelled most of the time with two d’s. Also the name of VilhjÁlmur StefÁnsson (who was born as William Stephenson) was spelled in several different ways. These have not been corrected. The also mentioned Stevenson is somebody else. Also: The index has not been checked for errors, besides the ones in the list above. |
