Mr Huxley--whom Mr Pearson does not asperse as a "Materialist"--has expressed himself in terms almost identical with Büchner's.[91] To speak of "mind-stuff" as being part of the "primal world-mist" is merely to suggest a hopeless "conceptual mode" of thought over and above the most exact "shorthand" to which words can well reduce the inferences of science as to cosmic history. That Clifford would have approved of either the tone or the judgment of his successor in the matter one may take leave to doubt. His "temperament" was different from that of Mr Pearson, who supplies in his own person the disproof of his own primitive doctrine that scientific opinions have nothing to do with temperament. [Footnote 90: Section on the "Value of Matter" (_Werth des Stoffs_), _end_.] [Footnote 91: See his "Critiques and Addresses," p. 306.] The unpleasing fact is that personal interest and prejudice have been the main factors in establishing the ill-repute of the term "Materialist." It arose very much as the term "Freethinker" arose, by way of broadly marking off a new tendency in active thought. The Freethinkers, so-called, simply claimed to follow their reason freely, where religious people were tied down to their traditional creed. The Materialists simply emphasized the new and spreading conception--at once Pantheistic and Atheistic--that the laws of things were to be looked for in the constitution of things, and not in any "spiritual" volition of a superior being or beings. They opposed the notion of a primal distinction between matter and the energies and activities thereof. Spiritism was for them the sum-total of all the guesses and hallucinations of ignorance; and their contrasted Materialism was imputed to them as a vileness by the types of mind which found elevation in the doctrine of blood sacrifice and ritual theophagy. Scientific disinterestedness was bracketed with grossness of life, and this often by pietists as gross in life as in thought. Every Spiritist who went a certain way in Materialism was libelled in turn; but the semi-Materialist could always indemnify himself by libelling those who went further.[92] Newton's theistic theory of matter is as absurd a one as any man of science ever framed; but he has earned by it the tenderness of later theists, while his fame secures the lenity of later physicists. Thus some guarded rationalists who pounce like weasels on every slip, real or fancied, of professed Freethinkers, honey their voices to speak of halfway thinkers whose slips are gross, open, palpable. They have their social reward. Bradlaugh and Büchner have taken a different course. Finding the term "Materialism" in itself unphilosophic, they have still looked to the essential point of its broad historic significance. It marks on the side of physical science, from La Mettrie onwards, the repudiation of theological methods; and though they would not have coined the name for themselves, they have
