Uncertainty: individuals, institutions and technology

In an attempt to refine the concept of uncertainty, this paperelaborates an ontology of the social world concentrating onindividuals, institutions and technology. It shows the strongentwinement of the ontological aspects of the conceptualisationof uncertainty and epistemological ones. It highlights the ontologicaland epistemological dimensions of different concepts of uncertainty,such as fundamental uncertainty, procedural uncertainty, ambiguityand weak uncertainty (or risk). It also comments on a few writingsthat distinguish varieties of uncertainty with adjectives suchas ‘ontological’ and ‘epistemological’or ‘epistemic’.
