Abstract

According to the Ontology of Knowledge (OK) reality is unspeakable, it is subjected neither to form nor to time (see ref OK). The concepts of necessity and indeterminacy are central for the OK. It is important to understand their meaning in such a context. Relativity offers a model of reality: The block-universe which is not "in" time but "contains" time. The same questions of necessity and indeterminacy therefore arise, but this time in the context of a model of sayable reality. Although the operational model of relativity is not an ontological model, it is in the context of relativistic space-time that we will try to understand the place left to indeterminacy. We will then try to transpose this understanding to the OK.
