Who gets to contribute to knowledge production of an epistemic community? Scholarship has focussed on unjustified forms of exclusion. Here I study justified forms of exclusion by investigating the phenomenon of so-called ‘cranks’ in mathematics. I argue that workload-management concerns justify the exclusion of these outsiders from mathematical knowledge-making practices. My discussion reveals three insights. There are reasons other than incorrect mathematical argument that justify exclusions from mathematical practices. There are instances in which mathematicians are justified in rejecting even correct mathematical arguments. Finally, the way mathematicians spot mathematical crankery does not support the pejorative connotations of the ‘crank’ terminology.

Abstract The Caesar problem arises for abstractionist views, which seek to secure reference for terms such as ‘the number of $X$s’ or $#X$ by stipulating the content of ‘unmixed’ identity contexts like ‘$#X = #Y$’. Frege objects that this stipulation says nothing about ‘mixed’ contexts such as ‘$# X = text{Julius Caesar}$’. This article defends a neglected response to the Caesar problem: the content of mixed contexts is just as open to stipulation as that of unmixed contexts.
凯撒问题出现在抽象主义的观点中，它试图通过规定“未混合”的身份上下文的内容，如“$#X = #Y$”，来确保对诸如“$X$s的数量”或“$#X$”等术语的引用。弗雷格反对说，这一规定没有提到“混合”上下文，如“$# X = text{Julius Caesar}$”。本文为对凯撒问题的一种被忽视的回应进行了辩护:混合上下文的内容与非混合上下文的内容一样可以规定。

This note defends the reduction of ordinals to pure sets against an argument put forward by Beau Madison Mount. In the first part I will defend the claim that dependence simpliciter can be reduced to immediate dependence and define a notion of predecessor dependence. In the second part I will provide and defend a way to model the dependence profile of ordinals akin to Mount’s proposal in terms of immediate dependence and predecessor dependence. I furthermore show that my alternative dependence profile allows us to single out the reduction of ordinals to von Neumann ordinals as the only viable set-theoretic reduction.

In their recent article ‘Resolving Frege’s other Puzzle’ Eric Snyder, Richard Samuels, and Stewart Shapiro defend a semantic type-shifting solution to Frege’s other Puzzle and criticize my own cognitive type-shifting solution. In this article I respond to their criticism and in turn point to several problems with their preferred solution. In particular, I argue that they conflate semantic function and semantic value, and that their proposal is neither based on general semantic type-shifting principles nor adequate to the data.
Eric Snyder、Richard Samuels和Stewart Shapiro在他们最近的文章《解决Frege的另一个谜题》中为Frege的其他谜题的语义类型转换解决方案辩护，并批评了我自己的认知类型转换解决方法。在这篇文章中，我回应了他们的批评，并指出了他们首选解决方案的几个问题。特别是，我认为他们将语义功能和语义价值混为一谈，他们的建议既不基于一般的语义类型转换原则，也不适合数据。
