Abstract

According to the Ontology of Knowledge (OK) reality is unspeakable, it is neither subject to form nor to time (see ref. OdC). The OK does not claim to tell an ontological truth (which would be unspeakable) but to propose an ontological model deepened in comparison to the common sense model. Relativity proposes the model of reality designated as the block-universe which is not in time but which contains time. Relativity is a scientific theory which abstains as much as possible from ontological pretension. In the absence of a passing time, the same questions of necessity and indeterminacy arise for both theories although in different contexts. It is by comparing these two theories that we will try to understand the place left to indeterminacy in the block-universe of Relativity.
