The superiority of the Deductive Method, both in its mode of advancing to the discovery of new truth and in the precision, clearness, and certainty which accompany its findings, must now easily become apparent. Whether we regard Induction and Deduction as correlative Processes belonging to one Method, each of which has been disproportionately in vogue at different epochs, or as distinctive Methods, having each their own Deductive and Inductive Processes, in either aspect, Induction is only a preparative labor, leading in the more important work of the application of the Law or Principle derived. It is only, indeed, for the purpose of discovering this Law that Observation, Classification, and Induction are undertaken. It has been the triumphant boast of the Inductive Method, that it guarded, by means of these preliminary steps, in the most careful manner, against error in establishing its Laws. To the extent of its capacity it has done so. But we have already seen, that deriving its Principles, as it was obliged to, from less than _all_ the Facts which appertained to the Principles, these must inevitably have been lacking in some particulars; it being impossible to make the whole out of less than all its parts. The Inductive Method has obtained an importance greatly exaggerated, for the reason that it has been brought into comparison, for the most part, with the Anticipative or Hypothetical, the bastard Deductive Method only, and its superiority over this exhibited in the most detailed manner, while the right application of the Deductive Method, except in Mathematics, has not been considered possible. The reason of this can be made obvious.
