If our candidate conceptual analysis were an explicit verbal definition, in the vocabulary of microphysics, then we could be sure that the analogue of premise was a microphysical truth, but once we move to the more abstract and unconstrained representation of meaning given by the two-dimensional intensional framework, we can no longer assume that this premise is necessitated by microphysical theory, and even if we could assume this, it is not clear what it would mean to say that this premise is deducible a priori from microphysics.

如果我们的候选概念分析是一个语词的显定义『an explicit verbal definition』，那么我们可以确信类似前设是一个微观物理真，但一旦我们移入基于二维内涵框架给出的更多抽象和不受约束的意义表达后，我们不再假设这个前设在微观物理理论上是必要的；即使我们能够假设这，也不清楚说'这个前设从微观物理学先天演推得到'究竟是什么意思。
