However, we will still count as making judgements and inferences. Riemann and other non-Euclideans make rational judgements about ways space can be. They go on to reason about space in a discursive fashion, solve logical puzzles etc. This brings us to the second similarity between the laws of logic and the truths of arithmetic that Frege points out in FA. If we reject the laws of arithmetic, we indirectly reject norms for thinking about the realm of the countable. But, argues Frege, the realm of the countable includes everything thinkable.

FA: 115) Frege published four books in his lifetime: Concept Script, a Formula Language of Pure Thought Modelled upon the Formula Language of Arithmetic (Begriffsschrift, eine der Arithmetischen nachgebildete Formelsprache des reinen Denkens, 1879), The Foundations of Arithmetic (Die Grundlagen der Arithmetik, 1884) and Basic Laws of Arithmetic I (Grundgesetze der Arithmetik I, 1893 and II, 1903). In the last two books he sets out to prove the truths of arithmetic from the laws of logic on the basis of suitable definitions of concepts such as number.
