I argue that no successful version of Williamson's anti‐luminosity‐argument has yet been presented, even if Srinivasan's further elaboration and defence is taken into account. There is a version invoking a coarse‐grained safety condition and one invoking a fine‐grained safety condition. A crucial step in the former version implicitly relies on the false premise that sufficient similarity is transitive. I show that some natural attempts to resolve this issue fail. Similar problems arise for the fine‐grained version. Moreover, I argue that Srinivasan's defence of the more contentious fine‐grained safety condition is also unsuccessful, again for similar reasons.

反光度论证的一些问题

我认为，即使考虑到 Srinivasan 的进一步阐述和辩护，威廉姆森的反光度论证还没有成功的版本。有调用粗粒度安全条件的版本和调用细粒度安全条件的版本。前一个版本中的一个关键步骤隐含地依赖于足够相似性是可传递的错误前提。我表明一些解决这个问题的自然尝试失败了。细粒度版本也会出现类似的问题。此外，我认为 Srinivasan 对更具争议的细粒度安全条件的辩护也不成功，同样出于类似的原因。
