Returning to the lacunae which it so amazes Fabre to discover in our organization, even in the most perfect of us, are they fundamentally very real? These mysterious and unknown senses which he has so greatly contributed to elucidate in the case of the inferior species: why, he asks, have we not inherited them, if we are truly the final term and the supreme goal of creation? But in cultivating our intuition, as Bergson invites us to do, would it be impossible to re-awaken, deep within us, these strange faculties, which perhaps are only slumbering? What of that species of indefinable memory which permits the red ant, the Bembex, the Cerceris, the Pompilus, the Chalicodoma and so many others to "find themselves," to orientate themselves with infallible certainty and incredible accuracy? Is it not to be found, according to travellers, in those men who have remained close to nature and accustomed from their remotest origins to listen to the silence of the great deserts? Finally, the evolutionists, who "reconstruct the world in imagination," and who see in the relationship of neighbouring species a proof of descent or derivation, and a whole ideal series, will not fail to perceive throughout his work, in the elementary operations of the Eumenes and the Odynerus, cousins of the Cerceris, which sting their prey in places as yet ill determined, not indeed so many isolated attempts, but an incomplete process of invention, an attempt at procedures still in the fact of formation: in a word, the birth of that marvellous instinct which ends in the transcendent art of the Sphex and the Ammophila. Although they have acquired such prodigious deftness, these master paralysers are not, in fact, always infallible. Occasionally the Sphex blunders and gropes, "operates clumsily"; the cricket revives, gets upon its feet, turns round and round, and tries to walk. But, inquires Fabre, do you say that having profited by a fortuitous act, which has turned out to be favourable to them, they have perfected themselves by contact with their elders, "thanks to the imitation of example," and that they have thus crystallized their experiences, which have been transmitted by heredity-- thereby fixed in the race? (9/7.) How much we should prefer that it were so! How much more comprehensible and interesting their life would become! But "when the hymenopteron breaks its cocoon, where are its masters! Its predecessors have long ago disappeared. How then can it receive education by example?"
