This thirty-first issue of AutoRicerca, published in both English and Italian, contains two articles. The first is probably the most comprehensive and convincing account to date of the ontology and metaphysics underlying the conceptuality interpretation of quantum mechanics. The second, is a more personal article, in which Massimiliano Sassoli de Bianchi, one of Aerts’ closest collaborators, revisits the beginning of his scientific collaboration with the latter, which began more than twenty years ago.
