    The most difficult problem that Leniewski came across in constructing his system of the foundations of mathematics was the problem of defining definitions, as he used to put it. He solved it to his satisfaction only when he had completed the formalization of his protothetic and ontology. By formalization of a deductive system one ought to understand in this context the statement, as precise and unambiguous as possible, of the conditions an expression has to satisfy if it is added to (...)

With this aim in view a system of Lesniewski's Ontology, referred to as System S, is outlined. Equipped with appropriate definitions and illustrated with a selection of theses it offers a logical theory of existence and non-existence. The usefulness of the theory is then tested by interpreting in its terms some of the principal notions (...)

    According to the author, no body of theories deserves to be called philosophy unless some of these theories and problems fall within the province of metphysics. No problems deserves the name of metaphysics unless some of them add up to constitute ontology. The author presents the reistic version of the science of being as the union of Protothetic, Ontology, Mereology and Chronology. The next possible step in the construction of the reistic ontology will be Stereology (a kind of reistic geometry).
