We may aptly finish these remarks by a quotation from Whewell's Aphorisms on the Language of Science. (Aphorism I., Philosophy of the Inductive Sciences, II. 483.) "Words borrowed from common language, and converted by scientific writers into technical terms, have some advantages and some disadvantages. They possess this great convenience, that they are understood after a very short explanation, and retained in the memory without effort. On the other hand they lead to some inconvenience; for since they have a meaning in common language, a careless reader is prone to disregard the technical limitation of this meaning, and to attempt to collect their import in scientific books, in the same vague and conjectural manner in which he collects the purpose of words in common cases. Hence the language of science, when thus resembling common language, is liable to be employed with an absence of that scientific precision which alone gives it value. Popular writers and talkers, when they speak of _force_, _momentum_, _action_, _and reaction_, and the like, often afford examples of the inaccuracy thus arising from the scientific appropriation of common terms." A similar line of reflection led Coleridge to remark (Biog. Lit., Chap. x.) that "the language of the market would be in the schools as _pedantic_, though it might not be reprobated by that name, as the language of the schools in the market. The mere man of the world, who insists that no other terms but such as occur in common conversation should be employed in a scientific disquisition, and with no greater precision, is as truly a _pedant_ as the man of letters, who, either over-rating the acquirements of his auditors, or misled by his own familiarity with technical or scholastic terms, converses at the wine-table with his mind fixed on his museum or laboratory." And such pedantry is, we may add, not uncommonly just as perspicuous as the definition which, says old Glanvill, "was lately given of a _Thought_ in a _University Sermon_--viz. _A Repentine Prosiliency jumping into Being_." (_Defence of the Vanity of Dogmatizing_, Actio Decima, p. 61, ed. 1.) C.--HUME ON THE ANALOGIES OF ART AND NATURE. [_Referred to in footnote (e) in the preceding Chapter._] The statement in the text is shaped as a not unfairly urged scientific objection of the kind which might be raised by some actual craftsman or producer. An objection identical in essence is thrown by Hume into a refined semi-metaphysical shape, and made to turn upon our general acquaintance with Human nature contrasted with our general ignorance of the Divine. It runs as follows:--
