In the new light which the theory of relativity has cast over Science, we see that a material ether filling space could only be accompanied by a material ether filling time-the two stand or fall together.
In the beginning of the chapter he clarifies the subject further "It may be well to state our conclusion in advance It is, in brief, that the ethers and their undulations, the waves which form the universe, are in all probability fectitious This is not to say that they have no existence at all, they exist in our minds, or we should not be discussing them, and something must exist outside our minds to put this or any other concept into our minds.
