The novely of the semantics consists in the analysis of (ii), which is made precise as: the distance between the closest B-worlds and the closest non-B-worlds is smaller than the distance between the closest A&amp;B-worlds and the closest A&amp;non-B-worlds. I will explain how the required ordering of distances between worlds can be captured in non-numerical terms, what the logic is like that is sound and complete with respect to the semantics, what a probabilistic version of the semantics looks like, and why the system is to be preferred over other recent semantics and logics of conditionals that analyse (ii) above differently.<\/p>\n<p>(This is joint work with Hans Rott.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract: In my talk I will present a new semantics for conditionals according to which &#8220;if A then B\u201c is true in case (i) the corresponding Stalnaker-Lewis conditional is true,&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","meta":{"_tribe_events_status":"","_tribe_events_status_reason":"","_tribe_events_is_hybrid":"","_tribe_events_is_virtual":"","_tribe_events_virtual_video_source":"","_tribe_events_virtual_embed_video":"","_tribe_events_virtual_linked_button_text":"","_tribe_events_virtual_linked_button":"","_tribe_events_virtual_show_embed_at":"","_tribe_events_virtual_show_embed_to":[],"_tribe_events_virtual_show_on_event":"","_tribe_events_virtual_show_on_views":"","_tribe_events_virtual_url":"","footnotes":""},"tags":[],"tribe_events_cat":[25],"class_list":["post-16189","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-metaphysics-and-logic-group","cat_metaphysics-and-logic-group"],"_links":{"self":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events\/16189","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":0,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events\/16189\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/media?parent=16189"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tags?post=16189"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events_cat?post=16189"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
