 The summary of Dedekind’s position in this section highlighted logical issues (his basic logical notions and procedures, compared both to Frege and to axiomatic set theory) and metaphysical issues (Dedekindian abstraction and creation, the structural nature of mathematical objects). However, there is another dimension of his position—another sense in which Dedekind’s approach represents a unique combination of logicism and structuralism—that deserves philosophical attention. That side involves primarily methodological and epistemological aspects. Some of those aspects already played a role in our discussions of his overtly foundational writings; but in order to shed more light on them, it helps to turn to his other mathematical work, starting with algebraic number theory.
