The drama of evolution as unfolded by science inevitably suggests that in the fortunes and life of humanity is to be heard the _motif_ of nature's music, unless indeed all is chaos and discord. The diapason ends full in man, or rather begins in man and the history of his life upon the earth. It may still be believed--because of evolution avowedly, or in spite of evolution--that man is a happy or an unhappy accident, a sport, a monstrosity, the miscarriage of an ape, a _faux pas_ of nature, the strangest event in a purposeless series; or man may be regarded, with much to support such an interpretation, as the intended goal of evolution, giving significance, rationality and purpose to the whole history. However slow and gradual the steps by which man has been produced, and however mechanical in one aspect the process, it may be insisted that a mechanism so perfect as to produce the varied forms of organic life, culminating in man, with his mental and moral endowments, is as strong evidence as could be produced of purpose as the ultimate and only explanation of the mechanism. Certainly the difficulty of evolving the fit from the fortuitous becomes accentuated when man is included within the series. Man, a purposive and moral being, sees in himself and the structure of his mind and the experience of his life the crowning evidence of the action of purpose. If the cause must be adequate to produce the effect, man cannot regard himself as the product of an accidental or mechanical process from whose inception and operation the action of intelligence is excluded. In a word, a purposive being cannot have been the result of a purposeless process. It is significant that those who have interpreted evolution to the masses have quite uniformly done so in terms of progress. But progress is a teleological conception. In a world where atoms shift unceasingly, but without the guidance of intelligence or will, there may be change but there will be no progress; for one arrangement of atoms will be as high in the scale of values as another. Evolutionists who, as evolutionists, are inspired with an ideal of human progress must in some sense be finalists. If the history of the world and of man presents any real progress, it can only be because it is in so far an expression of purpose. 2. It is an example of what Cardinal Newman called the development of doctrine that the theory of Evolution has come to mean, in popular regard, quite the opposite of what it meant etymologically or in the mind of its early advocates. Evolution means the unfolding of what was enfolded, either in primordial living germs or, to go still further back, in the primitive star-dust. Whatever is in the product must be read back into the elements from which it emerged, and a complete knowledge of these elements and their properties would thus disclose potencies for the production, under suitable conditions, of the completed development.
