Our primitive ancestors lived _with_ the animals, in the midst of them. And as soon as they began to bring some order into their observations of nature, and to transmit them to posterity, the animals and their life supplied them with the chief materials for their unwritten encyclopaedia of knowledge, as well as for their wisdom, which they expressed in proverbs and sayings. Animal psychology was the first psychology man was aware of--it is still a favourite subject of talk at the camp fires; animal life, closely interwoven with that of man, was the subject of the very first rudiments of art, inspiring the first engravers and sculptors, and entering into the composition of the most ancient epical traditions and cosmogonic myths.... The first thing which our children learn in natural history is something about the beasts of prey--the lions and the tigers; But the first thing that primitive savages must have learned about nature was that it represents a vast agglomeration of animal clans and tribes; the ape tribe, so nearly related to man, the ever-prowling wolf tribe, the knowing, chattering bird tribe, the ever-busy insect tribe, and on. For them the animals were an extension of their own kin--only so much wiser than themselves. And the first vague generalisation which men must have made about nature--so vague as to hardly differ from a mere impression--was that the living being and his clan or tribe are inseparable. _We_ can separate them--_they_ could not; and it seems even doubtful whether they could _think_ of life otherwise than within a clan or a tribe.... And that man who had witnessed once an attack of wild dogs, or dholes, upon the biggest beasts of prey, certainly realised, once and for ever, the irresistible force of the tribal unions, and the confidence and courage with which they inspire every individual. Man made divinities of these dogs, and worshipped them, trying by all sorts of magic to acquire their courage.
