Even if one had such an analysis (of the form "water is the unique waterish stuff "), another assumption of the argument would still fail, since the claim that H20 is the unique waterish stuff would not be a microphysical claim.

即使某人有一个这样的分析（形如：水是这些唯一的水性材料），论证的另外的预设也会失败，因为主张'H2O是这些唯一的水性材料'不会是微观物理学主张。
