whence he concluded, that there must needs be a Plurality in his own
Essence, and not only in his own but in every other also.

§ 33. Then he enter'd upon another sort of Speculation of the second
kind, by which he perceiv'd that tho' the parts of his Body were many,
yet they were Conjoyned and Compacted together so as to make one Body,
and that what difference there was between them consisted only in the

Liquor should be pour'd out into several Dishes and afterwards put all
together again in one Vessel; this Liquor would still be the _same_, as
