Abstract
The stream of books and papers devoted to the bearing of modern physics upon philosophical problems is apparently endless. Nevertheless, I am, I think, safe in asserting that the relations between physics and philosophy are still far from satisfactory. If, then, I venture to add one more paper to the stream, it is not because I believe that I am in a position to succeed where so many have failed, but because I have a suggestion to offer which, while it has not hitherto to my knowledge been made, would, if it could be accepted, throw some light upon one aspect of the vexed question of the status of the physical world
