He enlarged on the point, with display of learning, yet studiously avoiding the tone of pedantry. 'Evolution,' he remarked, when the dialogue had again extended its scope, 'does not touch the evidence of design in the universe; at most it can correct our imperfect views (handed down from an age which had no scientific teaching because it was not ripe for it) of the mode in which that design was executed, or rather is still being executed. Evolutionists have not succeeded in explaining life; they have merely discovered a new law relating to life. If we must have an explanation, there is nothing for it but to accept the notion of a Deity. Indeed, how can there be religion without a divine author? Religion is based on the idea of a divine mind which reveals itself to us for moral ends. The Christian revelation, we hold, has been developed gradually, much of it in connection with secondary causes and human events. It has come down to us in anything but absolute purity--like a stream which has been made turbid by its earthly channel. The lower serves its purpose as a stage to the higher, then it falls away, the higher surviving. Hitherto, the final outcome of evolution is the soul in a bodily tenement. May it not be that the perfected soul alone survives in the last step of the struggle for existence?' Peak had been talking for more than a quarter of an hour. Under stress of shame and intellectual self-criticism (for he could not help confuting every position as he stated it) his mind often wandered. When he ceased speaking there came upon him an uncomfortable dreaminess which he had already once or twice experienced when in colloquy with Mr. Warricombe; a tormenting metaphysical doubt of his own identity strangely beset him. With involuntary attempt to recover the familiar self he grasped his own wrist, and then, before he was aware, a laugh escaped him, an all but mocking laugh, unsuitable enough to the spirit of the moment. Mr Warricombe was startled, but looked up with a friendly smile. 'You fear,' he said, 'that this last speculation may seem rather fanciful to me?' Godwin was biting his lip fiercely, and could not command himself to utterance of a word. 'By no means, I assure you,' added the other. 'It appeals to me very strongly.' Peak rose from his chair. 'It struck me,' he said, 'that I had been preaching a sermon rather than taking part in a conversation. I'm afraid it is the habit of men who live a good deal alone to indulge in monologues.' On his return home, the sight of _Bibel und Natur_ and his sheets of laborious manuscript filled him with disgust. It was two or three days before he could again apply himself to the translation. Yet this expedient had undoubtedly been of great service to him in the matter of his relations with Mr. Warricombe. Without the aid of Reusch he would have found it difficult to speak naturally on the theme which drew Martin into confidences and established an intimacy between them.
