Jc Beall’s off-topic interpretation of Weak Kleene logic offers a logic of ‘true-and-topic’ preservation. However, Nissim Francez has recently argued that being ‘off-topic’ is a relational and not an _absolute_ semantic property; as such, it fails to satisfy the conditions of truth-functionality. For Francez, this means that it ‘cannot serve as an interpretation of a truth-value’. In this paper, I propose a two-layered _re_interpretation of Beall’s off-topic semantics. This two-layered framework has two crucial features: a sentential topic-tagging device and a (...) two-layered evaluation tool. I show that this framework results in a logic that preserves Beall’s key insight and addresses Francez’s concerns. (shrink)

Sally Haslanger is Ford Professor of Philosophy and Women's and Gender Studies at the Massachusetts Institute of Technology and a leading contemporary feminist philosopher. She has worked on analytic metaphysics, epistemology, and ancient philosophy. Her areas of interest are social and political philosophy, feminist theory, and critical race theory. Her 2012 book, Resisting Reality: Social Construction and Social Critique, collects papers published over the course of twenty years that link work in contemporary metaphysics, epistemology, and philosophy of language with social (...) and political issues concerning gender, race, and the family. It was awarded the 2014 Joseph B. Gittler Prize for “outstanding scholarly contribution in the field of the philosophy of one or more of the social sciences.” In this interview, done in the wake of the COVID-19 pandemic and the #BlackLivesMatter movement, we discuss her ideas on social practices, social structure, and structural explanation. We also delve into her debunking project of elucidating the notion of ideology in a way that links it with contemporary work in epistemology, philosophy of language, and philosophy of mind, and to do justice to the materiality of social practices and social structures.

In his Formal Logic, Arthur N. Prior declared that Jan Łukasiewicz's logical notation is ‘unquestionably the best logical symbolism for most purposes’. Whether he had a substantive, and...

In this interview with W. Alton Jones Professor of Philosophy at Vanderbilt University, Lucius T. Outlaw, Jr, we discuss the metaphysical and ethical questions of grouping and classifying people in terms of race and ethnicity. Outlaw is the author of [On Race and Philosophy] and one of the recognised pioneers of Africana Philosophy. Outlaw talks about growing up in racial segregation in Starkville, Mississippi, the Black Power movement, the notion of the Black intellectual, scholarship and teaching, and philosophizing about race. (...) We discuss the ambiguity of the concept of philosophy of race and explore the concepts of raciality, categories, human sociality, evolution, and oppression. With his philosophical, political, and sociological influences, Outlaw asserts that racism makes no sense at all because the diversity of our species is one of our greatest assets; and in terms of survival, we are all of the same species though certain group-shared differences do matter.

In “Sideways Music”, Ned Markosian presents the aesthetic value variance of sideways music as a case against what the Spacetime Thesis—the thesis that time is one of four similar dimensions that make up spacetime. Critics have already raised worries about the premises of his argument. In this paper, I focus on Markosian’s assumed aesthetic realism. I argue that there is a version of aesthetic realism—a version that admits aesthetic value gluts—that is consistent with both the Spacetime Thesis and the aesthetic (...) variance of sideways music. If this is right, then sideways music may simply be a non-issue for proponents of the Spacetime Thesis. (shrink)

What would a romantic relationship between a biological human and an artificial intelligence system look like? The question is explored through a fictional correspondence between Alan Turing and Ada Lovelace.

The hit American TV show The Good Place has garnered quite a following in recent years. Its main premise implies a scorekeeping view of the afterlife. People who have collected enough credits in their earthly lives will make the cut and go to the Good Place, while those who do not will be banished to the Bad Place. We suggest that such a premise would have to come to terms with Ted Sider's puzzle about the compatibility of a binary afterlife (...) with God's divine attributes. (shrink)
