Our contribution is conceptual and clarificatory. We point out,\u00a0first, that while the iterative definition of common knowledge is central to the epistemic foundations of game theory, it is less so for theories of collective agency, that rather use \u201ccommon knowledge\u201d in the sense of publicity. Building on this observation, we propose to distinguish between internalist and externalist understandings of common knowledge and to associate the notion of publicity with the latter. This allows us to classify the different accounts of common knowledge that have by now been studied by logicians, game theorists, and philosophers, to defuse a recent debate in philosophy around the relation between common knowledge and publicity, and to put the emphasis on the conditions by which common knowledge and publicity emerge.\u00a0(This is joint work with Olivier Roy.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Common Knowledge and Publicity Sena Bozdag (University of Bayreuth) &nbsp; 5 June 2026, 16:00 (Lisbon Time \u2013 WET) Faculdade de Letras de Lisboa Sala Mattos Rom\u00e3o [C201.J] (Departamento de Filosofia) &nbsp; Abstract:\u00a0We study the relation between common knowledge and publicity, i.e. that certain events or facts are \u201dout in the open\u201d, or \u201dpublic\u201d in a [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"activitypub_content_warning":"","activitypub_content_visibility":"","activitypub_max_image_attachments":4,"activitypub_interaction_policy_quote":"anyone","activitypub_status":"federated","footnotes":""},"categories":[1],"tags":[],"class_list":["post-2353","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/posts\/2353","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/comments?post=2353"}],"version-history":[{"count":1,"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/posts\/2353\/revisions"}],"predecessor-version":[{"id":2354,"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/posts\/2353\/revisions\/2354"}],"wp:attachment":[{"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/media?parent=2353"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/categories?post=2353"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cful.letras.ulisboa.pt\/lancog\/wp-json\/wp\/v2\/tags?post=2353"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
