Abstract
A popular argument goes thus: This is a construction, hence it is not real. Adding an appropriate adjective (social, mental, human, …) in front of “construction” or cognate terms like “(legal) fiction” yields a whole family of related arguments, all of which, or so I will argue, are fallacious. Contrary to popular opinion, these arguments fail both on the epistemic and the ontic sense of construction. Ontic constructions exist at least at one point in time, while epistemic constructions may well correspond to reality. The motivation behind these fallacious arguments can often be found in a misconceived conception of ontology and reality. A full theory of reality must take constructed entities into account because important domains of reality (mental life, social reality, technical artefacts, art and fiction) essentially depend on mental or social constructions.
