The introduction of notations for these notions allowed Dedekind to state new theorems, now The introduction of notations for these notions allowed Dedekind to state new theorems, now recognized as the modular laws in lattice theory. Observing the dualism displayed by the theorems, Dedekind pursued his investigations on the matter.

This led him, twenty years later, to introduce Dualgruppen, equivalent to lattices [Dedekind,Dedekind, ].

After a brief exposition of the basic elements of Dualgruppe theory, and with the help of his Nachlass, I show how Dedekind gradually built his theory through layers of computations, often repeated in slight variations and attempted generalizations. I study the tools he devised to help and accompany him in his computations. I highlight the crucial conceptual move that consisted in going from investigating operations between modules, to groups of modules closed under these operations.

By using Dedekind’s drafts, I aim to highlight the concealed yet essential practices anterior to the published text. A road map of Dedekind’s Theorem Dedekind’s Theorem 66 states that there exists an infinite set. Its proof invokes such apparently non-mathematical notions as the thought-world and the self.

This paper discusses the content and context of Dedekind’s proof. It is suggested that Dedekind took the notion of thought-world from Lotze. The influence of Kant and Bolzano on the proof is also discussed, and the reception of the proof in the mathematical and philosophical literature is covered in detail.

With several examples, I suggest that this editorial work is to be understood as a mathematical With several examples, I suggest that this editorial work is to be understood as a mathematical activity in and of itself and provide evidence for it.

## Dedekind cut

The core idea of the theory is that boundaries and coincidences thereof belong to the essence of continua. Brentano is confident that he developed a full-fledged, Brentano is confident that he developed a full-fledged, boundary-based, theory of continuity ; and scholars often concur: To be clear, the theory of boundaries on which it relies, as well as the account of ontological dependence that Brentano develops alongside his theory of boundaries, constitute splendid achievements.

However, the passage from the theory of boundaries to the account of continuity is rather sketchy. I show that their paper provides an I show that their paper provides an arithmetical rewriting of Riemannian function theory, i. Then, through a detailed analysis of the paper and using elements of their correspondence, I suggest that Dedekind and Weber deploy a strategy of rewriting parts of mathematics using arithmetic, and that this strategy is essentially related to Dedekind’s specific conception of numbers and arithmetic as intrinsically linked to the human mind.

Frede, Dedekind, and the Modern Epistemology of Arithmetic. In early analytic philosophy, one of the most central questions concerned the status of arithmetical objects. Frege argued against the popular conception that we arrive at natural numbers with a psychological process of abstraction Frege argued against the popular conception that we arrive at natural numbers with a psychological process of abstraction.

Instead, he wanted to show that arithmetical truths can be derived from the truths of logic, thus eliminating all psychological components.

Meanwhile, Dedekind and Peano developed axiomatic systems of arithmetic. The differences between the logicist and axiomatic approaches turned out to be philosophical as well as mathematical. The approach here is two-fold. Then I will consider those views from the perspective of modern philosophy of mathematics and in particular the empirical dedekinnd of arithmetical cognition.

I aim to show that there is nothing to suggest that the axiomatic Dedekind approach could not provide a perfectly adequate basis for philosophy of arithmetic.

### Dedekind Research Papers –

In the XIX century in mathematics passes reforms of rigor and ground, begun by Cauchy and extended by Weierstrass. Set theory was created as generalization of arithmetic, but it became the foundation of mathematics. The main problems of mathematical analysis: The author of one of concepts, Richard Dedekind —claimed the freedom to create math mathematical objects with the condition of their consistency. In “Was sind und was sollen die Zahlen? The book is a re-edition of Russian translation of Richard Dedekind’s book “What are numbers and what should they be?

The preface by G. First I explicate the relevant details of structuralism, then I argue that the significance of the latter is twofold: This allows the in re structuralist to have a fully or thoroughly structuralist theory, like the ante rem structuralist, without having to reify the various specific structures that the ante rem realist does.

Concepts of a number of C. Dedekind and Frege on the introduction of natural numbers. In this paper I will discuss the philosophical implications of Dedekind’s introduction of natural numbers in the central section of his foundational writing “Was sind und was sollen die Zahlen? This comparison will be crucial not only to highlight Dedekind’s value as a philosopher, but also to discuss crucial issues regarding the introduction of new mathematical objects, about their nature and our access to them.
