Materialists themselves have felt the feebleness of their hypothesis; to support it they have invented a second hypothesis. "No force without matter, no matter without force," [Footnote 76] says Dr. Buchner, at the present day one of the most resolute interpreters of the doctrine. That is to say, not being able to explain facts by matter alone, as matter is observed and conceived naturally by the human mind, they endow matter with what they term force, a principle of movement and of production.
[Footnote 76: Le Materialisme contemporain en Allemagne, by M. Paul Janet, of the Institute, p. 20. 1864.]
"Matter and force are," it is now said, "inseparable; both have existed from all eternity." Thus, imperiously urged by instinct and by their observation of facts, they begin again by distinguishing and naming separately matter and force; then, all at once, they confound them, treat them as united in their essence and from all eternity, and conclude by believing that they have succeeded in giving an explanation of man and of the world!
In this, what do they more than add an abstraction to an abstraction, and an hypothesis to an hypothesis? We are here in the presence of facts that are certain and yet perplexing; in presence of an external world, which evidently has not always been such as it is, which had a beginning, which is continuing to develop itself according to certain laws, and which is tending to certain ends; in the presence, too, of man, evidently a being at once one and complex, identical and yet variable. The ancients gave names and explanations to those incontestible facts, but the names and explanations are now rejected! Still, names and explanations are needed; man must put something in the place of God, Creator, and Providence—in the place of mind, and matter, and soul, and body. It is not for the first time that man finds himself confronted by this necessity, or that he essays to satisfy it; many abstractions, many words, have been already employed for this purpose. God was replaced by nature, by substance, by cause; the human soul was transformed into vital principle; the vital principle was elevated to the dignity of soul. It seems that these words, these abstractions, have had their time and lost their credit; and so now it is force which replaces them; force is mind, force is soul, force creates, force is God. It is enough now that they incorporate force with body; the problem no longer exists; man and the universe are laid bare!
When Leibnitz, to combat the Idealism of Descartes, and the Pantheism of Spinoza, developed the idea of force, he did not foresee that that very notion would be one day made use of to reduce to nonentities God, the human soul, all real and personal being, all first and final cause; to reduce, in short, everything to a medley of mechanics and dynamics incarnate in matter!
However specious it may appear to superficial minds, or to minds prejudiced in its favor by the peculiar nature of their studies and of their habitual labors, Materialism, like Pantheism, is only an hypothesis—an hypothesis constructed by dint of mere abstractions and purely verbal assertions. These not only disregard or suppress the facts which they pretend to explain, but are in direct contradiction with facts themselves recognized and proved by psychological observation. It is, in effect, an hypothesis, (I am forced here to repeat what I before affirmed of Pantheism,) equally revolting to true science and to common sense.
The hypothesis of Materialism has but a single merit; it is more consistent than those of the other systems. But even to this merit Materialism loses its title whenever it shrinks from pushing its principles boldly to their consequences, whether philosophical or practical: that is to say, whenever it shrinks from denying man's liberty, a moral law, the necessary principles of the human mind—whenever, in short, it shrinks from proclaiming its ultimate results, which are, as M. Damiron puts them, Fatalism, Egotism, Atheism. Philosophers are right in seeking for truth and in respecting truth for itself and at every risk; but there are some consequences which are the clearest evidence of a vice in principle; and this vice, in Materialism, is the blind forgetfulness of the best proved facts and the most essential elements of human nature.
