In Foundations of Institutional Reality Andrei Marmor provides a novel account of the ontological foundations of institutional facts and argues that there are important epistemic and methodological implications that follow from this ontology. The book offers a grounding-reductive account of collective attitudes that comports with methodological individualism. It argues for a functional explanation of the constitutive relations between rules and practices,
challenging Searle's influential distinction between constitutive and regulative rules.
