[Footnote 34: Let us remark, in passing, how badly nature has organised the system of communication between thinking beings. In what we experience we have nothing in common with our fellows; each one experiences his own sensations and not those of others. The only meeting point of different minds is found in the inaccessible domain of the _noumena._]

[Footnote 36: This seems to have been the opinion of Democritus. The modern doctrine of radiation from the human body, if established, would go nearly as far as the supposition in the text. Up till now, however, it lacks confirmation.--ED.]
[Footnote 37: I am compelled, much against my will, to use throughout this passage an equivocal expression, that of "mental law," or law of consciousness, or psychological law. I indicate by this the laws of contiguity and of similarity; as they result from the properties of the images, and as these are of a material nature, they are really physical and material laws like those of external nature. But how can all these laws be called physical laws without running the risk of confusing them one with the other?]
[Footnote 38: _Finality_ seems to be here used in the sense of the doctrine which regards perfection as the final cause of existence.--ED.]
[Footnote 39: See a very interesting article by E. GOBLOT, "La Finalité sans Intelligence," _Revue de Métaphysique_, July 1900.]
