But farther, the validity of the teleological argument depends upon the accuracy of our interpretation of those 'signs of intelligence' of which it makes so much, and which it interprets analogically in the light of human nature. But the 'interpreter' is ever 'one among a thousand.' Who is to guarantee to us that we have not erred as to the meaning of Nature's secret tracery? Who is to secure us against inerrancy in this? Before we deduce so weighty a conclusion from data so peculiar, we must obtain some assurance that no further insight will disallow the interpretation we have given. But is not this presumptuous in those who are acquainted in a very partial manner with the significance of a few of nature's laws? Who will presume to say that he has penetrated to the meaning of any one of these laws? And, if he has not done so, can he validly single out a few resemblances he has detected, and explain the nature of the infinite, by a sample of the finite? Nature is so inscrutable that, even when a law is discerned, the scientific explorer will not venture to say that he has read its character, so as to be sure that the law reflects the ultimate meaning of the several phenomena it explains. Nay, is he not convinced that other and deeper meanings must lie within them? A law of nature is but the generalized expression of the extent to which our human insight has as yet extended into the secret laboratory of her powers. But as that insight deepens, our explanations change. We say the lower law is resolved back into a higher one, the more detailed into the more comprehensive. But if our scientific conceptions themselves are thus constantly changing, progressing, enlarging, how can we venture to erect our natural theology on the surface interpretation of the fleeting phenomena of the universe? 'Lo, these are a part of His ways, but how little a portion is known of Him!' And this conclusion we advance against those who as dogmatically deny that there can be _any_ resemblance between the forces of nature as a revelation of the Infinite, and the volitional energy of man. Both assumptions are equally arbitrary and illegitimate. We shall shortly endeavour to show on what grounds (remote from teleology) we are warranted in believing that a resemblance does exist.
