The infidelity and the contempt for sacred and spiritual things which pervade so much of our modern literature are largely attributable to the prevalence of that form of philosophy which may be designated as Agnostic Evolution, and this in its turn is popularly regarded as a result of the pursuit of physical and natural science. The last conclusion is obviously only in part, if at all, correct, since it is well known that atheistic philosophical speculations were pursued, quite as boldly and ably as now, long before the rise of modern science. Still, it must be admitted that scientific discoveries and principles have been largely employed in our time to give form and consistency to ideas otherwise very dim and shadowy, and thus to rehabilitate for our benefit the philosophical dreams of antiquity in a more substantial shape. In this respect the natural sciences—or, rather, the facts and laws with which they are conversant—merely share the fate of other things. Nothing, however indifferent in itself, can come into human hands without acquiring thereby an ethical, social, political, or even religious, significance. An ounce of lead or a dynamite cartridge may be in itself a thing altogether destitute of any higher significance than that depending on physical properties; but let it pass into the power of man, and at once infinite possibilities of good and of evil cluster round it according to the use to which it may be applied. This depends on essential powers and attributes of man himself, of which he can no more be deprived than matter can be denuded of its inherent properties; and if the evils arising from misuse of these powers trouble us, we may at least console ourselves with the reflection that the possibility of such evils shows man to be a free agent, and not an automaton. All this is eminently applicable to science in its relation to agnostic speculations. The material of the physical and natural sciences consists of facts ascertained by the evidence of our senses, and for which we depend on the truthfulness of those senses and the stability of external nature. Science proceeds, by comparison of these facts and by inductive reasoning, to arrange them under certain general expressions or laws. So far all is merely physical, and need have no connection with our origin or destiny or relation to higher powers. But we ourselves are a part of the nature which we study; and we cannot study it without more or less thinking our own thoughts into it. Thus we naturally begin to inquire as to origins and first causes, and as to the source of the energy and order which we perceive; and to these questions the human mind demands some answer, either actual or speculative. But here we enter into the domain of religious thought, or that which relates to a power or powers beyond and above nature. Whatever forms our thoughts on such subjects may take, these depend, not directly on the facts of science, but on the reaction of our minds on these facts. They are truly anthropomorphic. It has been well said that it is as idle to inquire as to the origin of such religious ideas as to inquire as to the origin of hunger and thirst. Given the man, they must necessarily exist. Now, whatever form these philosophical or religious ideas may take—whether that of Agnosticism or Pantheism or Theism—science, properly so called, has no right to be either praised or blamed. Its material may be used, but the structure is the work of the artificer himself.
