Abstract
The present paper approaches ontology and meta-ontology through Mathematics, and more precisely through category theory. We exploit the theory of elementary toposes to claim that a satisfying ``theory of existence'', and more at large ontology itself, can both be obtained by means of category theory. For us, an ontology is a mathematical object: it is a category $E$, the universe of discourse in which our Mathematics (intended at large, as a theory of knowledge) can be deployed. The internal language that all categories possess, in the particular case of an elementary topos, is induced by the presence of an object $\Omega_E$ parametrizing the truth values of the internal propositional calculus; such pair $(E,\Omega_E)$ prescribes the modes of existence for the objects of a fixed ontology/category.
This approach resembles, but is more general than, the one leading to fuzzy logics, as most choices of $E$ and thus of $\Omega_E$ yield nonclassical, many-valued logics.
Framed this way, ontology suddenly becomes more mathematical: a solid corpus of techniques can be used to backup philosophical intuition with a useful, modular language, suitable for a practical foundation.
As both a test-bench for our theory, and a literary divertissement, we propose a possible category-theoretic solution of the famous Tlön's ``nine copper coins'' paradox, and of other seemingly paradoxical construction in Jorge Luis Borges' literary work.
We conclude with some vistas on the most promising applications of our future work.
