Hence, the present two-sided approach is a far-reaching generalization. It even leaves room for two extremes: pure theories of postulates and pure theories of models.<\/span><\/p>\n<p style=\"text-align: justify;\"><span lang=\"en-US\"> The recent paper is based on the simplest assumptions about the further nature of theories and their claims. Starting from this \u2018basic\u2019 version I want to examine in the present paper three perspectives for concretization, 1) a quantitative\/probabilistic version, 2) a refined version based on an underlying ternary similarity relation between possibilities (notably, structurelikeness between structures), 3) a <\/span><span lang=\"en-US\"><i>stratified<\/i><\/span><span lang=\"en-US\"> version based on a (theory-relative) distinction between an observational and a theoretical level. <\/span><\/p>\n<p><span lang=\"en-US\">Kuipers, T., (2000), <\/span><span lang=\"en-US\"><i>From Instrumentalism to Constructive Realism<\/i><\/span><span lang=\"en-US\">, Springer, Dordrecht, 2000.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>On Thursday January 21st, we will have a joint LogiCIC\/LIRa session with Theo Kuipers.
