 us, their souls really remain apart in worlds shut up from ours. But, when this bare possibility is excluded, the question stands thus. A common understanding being admitted, how much does that imply? What is the minimum of sameness that we need suppose to be involved in it?

It might be interesting elsewhere to pursue this question at length, but I must content myself here with an attempt briefly to indicate the answer. The fact is that, in the main, we behave as if our internal worlds were the same. But this fact means that, for each one, the inner systems coincide. Through all their detail these several orders must lead to the same result. But, if so, we may go further, and may conclude that each comes to the same thing. What is the amount of variety then which such coinciding orders will admit? We must, I presume, answer that, for all we know, the details may be different, but that the principles cannot vary. There seems to be a point beyond which, if laws and systems come to the same thing, they must be actually the same. And the higher we mount from facts of sense, and the wider our principles have become, the more nearly we have approached to this point of identity. Thus sensible qualities, we may suppose, at one end are largely divergent; while, if we rise high enough at the other end, we must postulate sameness. And, between these two extremes, as we advance, the probability increases that coincidence results from identical character. It is, for example, more likely that we share our general morality with another man, than that we both have the same tastes or odours in common. And with this I will pass from a subject which seems both difficult and interesting, but which for metaphysics possesses but secondary importance. Whatever variety there may be, cannot extend to first principles; and all variety comes together, and is transformed, in the Absolute.
