The issues dealt with include self-evidence and epistemic value with special emphasis on Axiom V, Frege\u2019s attitude towards Axiom V before and after Russell\u2019s discovery of the contradiction, as well as the possible role and the status of Hume\u2019s Principle in the wake of Russell\u2019s Paradox. In the central part, I pursue a twofold aim: (a) to shed new light on the connection between Frege\u2019s way of introducing the primitive function-names of his logical system and the requisite self-evidence of his axioms in whose expression such a function-name occurs; and (b) to examine the conflict between the requirements of self-evidence and real epistemic value arising inevitably and invariably from Fregean abstraction principles, if they are singled out as axioms of a theory <em>T<\/em>.<\/p>\n<p><strong>Organization:<br \/>\n<\/strong>Tsinghua University &#8211; University of Amsterdam Joint Research Centre for Logic<br \/>\nDepartment of Philosophy, Tsinghua University<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Time: 2017 Oct. 13,\u00a013:30-15:55 Venue:\u00a06B312, Classroom [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/posts\/908"}],"collection":[{"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/comments?post=908"}],"version-history":[{"count":3,"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/posts\/908\/revisions"}],"predecessor-version":[{"id":921,"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/posts\/908\/revisions\/921"}],"wp:attachment":[{"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/media?parent=908"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/categories?post=908"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/tsinghualogic.net\/JRC\/wp-json\/wp\/v2\/tags?post=908"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
