The Propriety of Miracles

In other words, there are rules behind the rules, and a unity which is deeper than uniformity. A supreme workman will never break by one note or one syllable or one stroke of the brush the living and inward law of the work he is producing. But he will break without scruple any number of those superficial regularities and orthodoxies which little, unimaginative critics mistake for its laws. The extent to which one can distinguish a just 'license' from a mere botch or failure of unity depends on the extent to which one has grasped the real and inward significance of the work as a whole. If we had grasped as a whole the innermost spirit of that 'work which God worketh from the beginning to the end', and of which Nature is only a part and perhaps a small part, we should be in a position to decide whether miraculous interruptions of Nature's history were mere improprieties unworthy of the Great Workman or expressions of the truest and deepest unity in His total work. In fact, of course, we are in no such position. The gap between God's mind and ours must, on any view, be incalculably greater than the gap between Shakespeare's mind and that of the most peddling critics of the old French school.
