outside the series, if unique, there would be no exclusiveness in space or time, but simply in quality. And all this again is but hypothetical, since in space or time it is not true that there is really but one series, and any such idea is a superstition which I venture to think is refuted in this work.[1] There are many series in time and space, and the unity of all these is not temporal and spatial. And from this it follows that, so far as we know, there might be counterparts, one or more, of anything existing in space or in time, and that, considered spatially or temporally, there would be between these different things absolutely no difference at all nor any possibility of distinction. They would differ of course, and their respective series would differ, but that difference would not consist in space or time but merely in quality.[2] And with this I will end what I have to say here on the chimæra of a difference in mere ‘existence.’
And obviously, as it seems to me, the objector to identity advances nothing new, when he brings forward the continuity of a thing in space or in time. The idea I presume is, as before, that in space or time we have a form of identity in difference which is in no sense an identity of character, but consists merely of ‘existence,’ and that a thing is qualified by being placed externally in this form. But the mere external qualification by the form, and the ‘existence’ of a form or of anything else which is not character, we have seen are alike indefensible; and, when the principle is refuted, it would seem useless to insist further on detail. Hence, leaving this, I will go on to consider a subsidiary mistake.
For the identity in time of an existing thing (as in this work I have mentioned) you require both temporal continuity and again sameness in the thing’s proper character. And mutatis mutandis what is true here about temporal continuity is true also about spatial, and not to perceive this would be an error. Now whether a wholly unbroken continuity in time or space is requisite for the singleness of a thing, is a question I here pass by;[3] but some unbroken duration obviously is wanted if there is to be duration at all. And the maintenance of its character by the thing seems to me also to be essential. The character of course may change, but this change must fall outside of that which we take to be the thing’s essential quality. For otherwise ipso facto we have a breach in continuity. And, though this matter may seem self-

- ↑ This holds again of my ‘real’ series in space or time. The foundation and differential character of that series lies, so far as I can see, in my special personal feeling, which, I presume, is qualitative. And I repeat here that, so far as we can know, there might be one or more exact duplicates of myself which would of course differ, but the differences of which would lie in some character falling outside what is observed by us.
