The goal of this paper is two-fold. The first is to show that Russell’s concerns cannot be dismissed on the grounds that they are external to the Tractarian project, deriving, perhaps, from logicist ambitions harbored by Russell but not shared by Wittgenstein. The extensibility of Wittgenstein’s theory of number to the case of transfinite cardinalities is, I shall argue, a <em>desideratum</em> generated by concerns intrinsic, and internal to Wittgenstein’s logical and semantic framework. Second, I aim to show that Wittgenstein’s theory of number as espoused in the <em>Tractatus</em> is consistent with Russell’s assessment, in that Wittgenstein meant to leave open the possibility that transfinite numbers could be generated within his system, but did not show explicitly how to construct them. To that end, I show how one could construct a transfinite number line using ingredients inherent in Wittgenstein’s system, and in accordance with his more general theories of number and of operations.</p> 2021-02-23T00:00:00+00:00 Copyright (c) 2021 James R Connelly Cheryl Misak, Frank Ramsey: A Sheer Excess of Powers 2021-02-14T23:45:07+00:00 Matthew Simpson 2021-02-23T00:00:00+00:00 Copyright (c) 2021 Matthew Simpson
