We have been considering this class of questions only as a naturalist might who sought for the proper or reasonable interpretation of the problem before him, unmingled with considerations from any other source. Weightier arguments in the last resort, drawn from the intellectual and moral constitution of man, lie on a higher plane, to which it was unnecessary for our particular purpose to rise, however indispensable this be to a full presentation of the evidence of mind in Nature. To us the evidence, judged as impartially as we are capable of judging, appears convincing. But, whatever view one unconvinced may take, it cannot remain doubtful what position a theist ought to occupy. If he cannot recognize design in Nature because of evolution, he may be ranked with those of whom it was said, "Except ye see signs and wonders ye will not believe." How strange that a convinced theist should be so prone to associate design only with miracle! All turns, however, upon what is meant by this Nature, to which it appears more and more probable that the being and becoming--no less than the well-being and succession--of species and genera, as well as of individuals, are committed. To us it means "the world of force and movement in time and space," as Aristotle defined it--the system and totality of things in the visible universe. What is generally called Nature Prof. Tyndall names matter--a peculiar nomenclature, requiring new definitions (as he avers), inviting misunderstanding, and leaving the questions we are concerned with just where they were. For it is still to ask: whence this rich endowment of matter? Whence comes that of which all we see and know is the outcome? That to which potency may in the last resort be ascribed, Prof. Tyndall, suspending further judgment, calls mystery--using the word in one of its senses, namely, something hidden from us which we are not to seek to know. But there are also mysteries proper to be inquired into and to be reasoned about; and, although it may not be given unto us to know the mystery of causation, there can hardly be a more legitimate subject of philosophical inquiry. Most scientific men have thought themselves intellectually authorized to have an opinion about it. "For, by the primitive and very ancient men, it has been handed down in the form of myths, and thus left to later generations, that the Divine it is which holds together all Nature;" and this tradition, of which Aristotle, both naturalist and philosopher, thus nobly speaks[XIII-5]--continued through succeeding ages, and illuminated by the Light which has come into the world--may still express the worthiest thoughts of the modern scientific investigator and reasoner.
