doubt perfectly true that each previous movement had been the necessary consequence of the force applied, just as truly as those which coincided with the conventions of the telegraphist's alphabet; but win any one say that such coincidence could conceivably be attributable to the forces of magnetism alone, however exact to the laws according to which they operate? It must always be remembered that the question we have to discuss is, how far Science casts any light upon such questions as the one before us. And since "Science" is taken to mean knowledge acquired through the observation of phenomena alone, we have at present to enquire whether material forces, the only ones of which observation directly tells us anything, could have produced such effects as we have considered, otherwise than by mere "Chance"? If they could not, is it imaginable that they produced these effects at all? And it appears obvious that unless there be Purpose at the back of Nature, Chance must be acknowledged as the architect of the universe. Professor Huxley tells us, it is true, that such an idea could be entertained by no one whose mind had ever been illumined by a ray of scientific thought. In face of this it is rather remarkable to find that the idea was undoubtedly entertained by Mr. Darwin, who took for granted that to deny Purpose is to affirm Chance. I am conscious [he wrote to Asa Gray][155] that I am in an utterly hopeless muddle. I cannot think that the world, as we see it, is the result of chance; and yet I cannot look at each separate thing as the result of Design. And again:[156] I cannot any how be contented to view this wonderful universe, and especially the nature of man, and to conclude that everything is the result of brute force. I am inclined to look at everything as resulting from designed laws, with the details, whether good or bad, left to the working out of what we call chance. Not that this notion _at all_ satisfies me. Professor Haeckel too is by no means in accord on this point with his friend Professor Huxley. He writes:[157]
