Granted, then, that certain transformations do happen, it is essential that we should regard them in the philosophic manner of fairy tales, not in the unphilosophic manner of science and the "Laws of Nature." When we are asked why eggs turn to birds or fruits fall in autumn, we must answer exactly as the fairy godmother would answer if Cinderella asked her why mice turned to horses or her clothes fell from her at twelve o'clock.

We must answer that it is _magic_.

It is not a "law," for we do not understand its general formula.

It is not a necessity, for though we can count on it happening practically, we have no right to say that it must always happen.

It is no argument for unalterable law (as Huxley fancied) that we count on the ordinary course of things.
