Monsieur de Montmorine was recaptured and brought to the scaffold, through the trifling circumstance of some chicken bones being found near the door of his landlady--a woman too poor to indulge in such dainties.* The discovery of de Montmorine was not, as at first sight appears, an inference from a single fact, but from an adjacent induction. It was a general truth, (known to the party who observed the bones) a truth inducted from a number of facts that poor people could not afford to luxuriate on chickens. It was, therefore, from this induction, inferred that some one of superior fortune must be living in that particular place. * Chambers' Miscellany of Useful and Entertaining Tracts, No. 61: the Story of Lavaiette, p. 27 The judicious care which the great fathers of science have exhibited in making their inferences, incontestably establishes their conviction of the danger of any other reasoning than that from inductions. Lord Brougham informs us, that what Newton's Principia is to science, Locke's essay to metaphysics, Demosthenes in oratory, and Homer in poetry, Cuvier's researches to our fossil osteology. But Cuvier never attempted to draw any inferences until he had examined the _whole_ osteology of the living species. Lord Brougham remarks, that 'from examining a _single_ fragment of bone we infer that, in the wilds where we found it, there lived and ranged, some thousands of years ago, an animal of a peculiar kind.' This is a case in which the inference spoken of is arrived at in a way different from that apparently stated. We recognise in the 'fragment of bone' a link in a chain of facts constituting the basis of a well-known induction, which comparative anatomy has many times verified. It is important to distinguish well the grounds from which accurate inferences, such as these in the cases before us, have really been adduced, in order to ascertain the grounds from which we should reason generally. It will be found that solid reasoning can only proceed from general rules--i.e., inductions from facts. It will be found that the prime source of fallacy lies in reasoning from isolated facts. It is not to be denied that such reasoning is sometimes right, but it is to be remembered that it is right by accident, not by design. There is no science or certainty in it. It is hazard, not logic.
