Chateaubriand’s Realist Conception of Logic

Abstract

I present the realist conception of logic supported by Oswaldo Chateaubriand which integrates ontological and epistemological aspects, opposing it to mathematical and linguistic conceptions. I give special attention to the peculiarities of his hierarchy of types in which some properties accumulate and others have a multiple degree. I explain such deviations of the traditional conception, showing the underlying purpose in each of these peculiarities. I compare the ideas of Chateaubriand to the similar ideas of Frege, Tarski and Gödel. I suggest a view of the logical properties in terms of the Aristotelian notion of focal meaning and I give a formal expression to the type of the entities in the hierarchy proposed by Chateaubriand.

A possible delimitation between facts and states of affairs

“…However, it differs from them in that it is flexible and cumulative. It is flexible because properties may have a variable arity, and it is cumulative because the logical properties may appear in different levels and combine with different kinds of entities (see Sautter 2010). This hierarchy will be further explained in the section "The Type Of Facts And Of States Of Affairs".…”
