But I think the main mistake of Mr. Wells’s philosophy is a somewhat deeper one, one that he expresses in a very entertaining manner in the introductory part of the new Utopia. His philosophy in some sense amounts to a denial of the possibility of philosophy itself. At least, he maintains that there are no secure and reliable ideas upon which we can rest with a final mental satisfaction. It will be both clearer, however, and more amusing to quote Mr. Wells himself.
He says, “Nothing endures, nothing is precise and certain (except the mind of a pedant). … Being indeed!—there is no being, but a universal becoming of individualities, and Plato turned his back on truth when he turned towards his museum of specific ideals.” Mr. Wells says, again, “There is no abiding thing in what we know. We change from weaker to stronger lights, and each more powerful light pierces our hitherto opaque foundations and reveals fresh and different opacities below.” Now, when Mr. Wells says things like this, I speak with all respect when I say that he does not observe an evident mental distinction. It cannot be true that there is nothing abiding in what we know. For if that were so we should not know it all and should not call it knowledge. Our mental state may be very different from that of somebody else some thousands of years back; but it cannot be entirely different, or else we should not be conscious of a difference. Mr. Wells must surely realize the first and simplest of the paradoxes that sit by the springs of truth. He must surely see that the fact of two things being different implies that they are similar. The hare and the tortoise may differ in the quality of swiftness, but they must agree in the quality of motion. The swiftest hare cannot be swifter than an isosceles triangle or the idea of pinkness. When we say the hare moves faster, we say that the tortoise moves. And when we say of a thing that it moves, we say, without need of other words, that there are things that do not move. And even in the act of saying that things change, we say that there is something unchangeable.
But certainly the best example of Mr. Wells’s fallacy can be found in the example which he himself chooses. It is quite true that we see a dim light which, compared with a darker thing, is light, but which, compared with a stronger light, is darkness. But the quality of light remains the same thing, or else we should not call it a stronger light or recognize it as such. If the character of light were not fixed in the mind, we should be quite as likely to call a denser shadow a stronger light, or vice versa. If the character of light became even for an instant unfixed, if it became even by a hair’s-breadth doubtful, if, for example, there crept into our idea of light some vague idea of blueness, then in that flash we have become doubtful whether the new light has more light or less. In brief, the progress may be as varying as a cloud, but the direction must be as rigid as a French road. North and South are relative in the sense that I am North of Bournemouth and South of Spitzbergen. But if there be any doubt of the position of the North Pole, there is in equal degree a doubt of whether I am South of Spitzbergen at all. The absolute idea of light may be practically
