 Now, if this is so, and some water can exist while being spread out, why suppose that that very same water came into existence only when poured into your cup (from, say, two bottles)? It seems like it could come into existence when joined only if it went out of existence when scattered. But it didn’t go out of existence when scattered—so it couldn’t have come into existence when joined. So, there always was this water fusion (at least as long as all the sub-portions of water existed). We can repeat the same argument for the copper in two distinct statues. There will also be the sum of the gold in Sweden and the lead in Tanzania, if we can replace the K in Summativity with ‘metal’.
