An example: Spinoza's Ontology, by Jan Hladik
Abstract. We examine the possibility of applying knowledge represen-
tation and automated reasoning in the context of philosophical ontology.
For this purpose, we use the axioms and propositions in the first book
of Spinoza's Ethics as knowledge base and a tableau-based satisfiability
tester as reasoner. We are able to reconstruct most of Spinoza's system
with formal logic, but this requires additional axioms which are assumed
implicitly by Spinoza. This study illustrates how tools developed in com-
puter science can be of practical use for philosophy.
