Warren appeared to take for granted, in a fashion typical of those who shared his prejudices, that it was impossible to find in Eocene strata implements of human manufacture, particularly those displaying a relatively high level of stoneflaking technique. Moir, as we have seen, expressed the same view—no toolmaking beings could have existed in the Eocene (Section 3.3.3). But those who are free from such prejudices might justifiably wonder whether Warren had actually discovered, in the Eocene strata of Essex, a genuine object of human manufacture.
A similar event occurred some years earlier in France, where H. Breuil, in attempting to prove the natural origin of eoliths by geological pressure, also found in an Eocene formation specimens exactly resembling Late Paleolithic stone tools (Section 3.4.2). Breuil, however, was convinced that humans could not have existed in the Eocene.
As we noted in a previous chapter (Section 2.9), T. McKenny Hughes also expressed a conviction that humans could not have existed as far back as the Eocene, despite the presence in an Eocene formation of pierced shark’s teeth like those made by today’s inhabitants of the South Pacific. Other finds of objects of human manufacture in formations that might be as old as the Eocene occurred in California (Section 5.5). In this context, Warren’s Bullhead Bed discoveries, if regarded as genuine implements, do not seem so out of place.
In the discussion that followed Warren’s report, Mr. Dewey, one of the scientists present, pointed out that in some cases the Kent eoliths and Moir’s rostro-carinates are found in the middle of Tertiary sedimentary beds and not directly on the hard chalk. This circumstance, said Dewey, would rule out the particular pressure explanation given by Warren.
Warren had displayed some specimens during his talk. But Reginald Smith complained that Warren (and Breuil in France) had compared their natural productions with only a few of the very poorest eolith specimens. Smith accused Warren of discouraging research in early deposits.
The record stated: “Mr. H. Bury thought it unfortunate that such a discussion should have been raised without a fair representation of both sides of the case among the exhibits. The author [Warren] and Mr. Haward had brought forward the best specimens that they could find in support of their case; but for comparison they only produced some half dozen very inferior Kentish eoliths, and no sub-Crag implements at all. It was a mistake to suppose that believers in Pliocene man had ignored these pressure-flaked flints from the Eocene beds; on the contrary, the differences in detail which they observed between the two categories formed an essential factor in their argument” (Warren 1920, p. 251).
Bury’s point is well worth noting, for one often encounters something like the following in discussions of eoliths by their detractors. The skeptical authority will point out that such and such scientist found in Tertiary strata stone objects he incautiously believed to be of human manufacture and that the discovery was a matter of controversy for some years until such and such scientist delivered his definitive report that conclusively demonstrated that the stone objects had been produced by the pressure of the overlying layers. But in recounting this history the skeptical authority ignores the fact that the original discoverer had carefully considered and dismissed that very possibility. In considering the eolith question with an open mind, one learns to be suspicious of definitive disproofs, which often turn out to be quite rickety intellectual contraptions.
The notes of the discussion also recorded the following ironic remarks by one of the members of the Geological Society: “Mr. A. S. Kennard congratulated the author [Warren] on an important discovery, and considered that the paper strongly supported the claim for the human origin of the Kentish eoliths. He agreed with the author that it was unfair to decide from a few examples, and that the proper test was the whole group. Judged by this standard, neither of the series shown [by Warren] resembled the Kentish eoliths, since the more numerous and characteristic specimens [shown by Warren] were quite unknown on the Plateau” (Warren 1920, p. 251). Kennard thus turned the tables on Warren, taking his attempt to dismiss the eoliths as proof of their genuineness.
