The prodigious complexity of the methods by which Science has arrived at conclusions so strangely in harmony with the ancient thought of the East, may suggest the doubt whether those conclusions could ever be made clearly comprehensible to the mass of Western minds. Certainly it would seem that just as the real doctrines of Buddhism can be taught to the majority of believers through forms only, so the philosophy of science can be communicated to the masses through suggestion only,—suggestion of such facts, or arrangements of fact, as must appeal to any naturally intelligent mind. But the history of scientific progress assures the efficiency of this method; and there is no strong reason for the supposition that, because the processes of the higher science remain above the mental reach of the unscientific classes, the conclusions of that science will not be generally accepted. The dimensions and weights of planets; the distances and the composition of stars; the law of gravitation; the signification of heat, light, and color; the nature of sound, and a host of other scientific discoveries, are familiar to thousands quite ignorant of the details of the methods by which such knowledge was obtained. Again we have evidence that every great progressive movement of science during the century has been followed by considerable modifications of popular beliefs. Already the churches, though clinging still to the hypothesis of a specially-created soul, have accepted the main doctrine of physical evolution; and neither fixity of belief nor intellectual retrogression can be rationally expected in the immediate future. Further changes of religious ideas are to be looked for; and it is even likely that they will be effected rapidly rather than slowly. Their exact nature, indeed, cannot be predicted; but existing intellectual tendencies imply that the doctrine of psychological evolution must be accepted, though not at once so as to set any final limit to ontological speculation; and that the whole conception of the Ego will be eventually transformed through the consequently developed idea of pre-existence.
