Species Selection and Traditional Concepts in Evolutionary Theory
An Interview with Stewart Shapiro
-———Illustrasjon: Oda Aurora Norlund———-
By the late nineteenth century logic had undergone a revolution. After almost two millennia of playing around with the limited theory of Aristotelian syllogisms, inference patterns of the form
All Bs are Cs
All As are Bs
Therefore, all As are Cs,
logicians, like Gottlob Frege and Charles Sanders Peirce, greatly advanced their subject. They developed formal languages and theories for the classical propositional calculus and predicate logic of first and second order that greatly outstripped the limits of the old syllogistic approach. Alternative theories of logic were also developed in the decades to follow, such as intuitionistic logic, while some theories fell somewhat out of favor (e.g. second order logic). Underlying logicians’ disagreement about what language to state logical theories in and what principles to count as logical was the question: what is the correct logic?
The Continuum Hypothesis and the Set-Theoretic Multiverse
An Interview with Herman Cappelen
-———Illustrasjon: Oda Aurora Norlund———-
Herman Cappelen is a professor of philosophy at the University of Oslo with a part-time position at the University of St. Andrews. He has published influential books and papers on many topics, especially in the philosophy of language but also philosophical methodology, epistemology, metaphysics, and philosophy of mind. In particular, he has worked on the topic of relativism about truth, and, together with John Hawthorne, he wrote the book Relativism and Monadic Truth (2009). The book presents and argues against relativism about truth, while maintaining that truth is a monadic property: if something is true, it is true full stop. In this interview, Cappelen discusses his understanding of relativism about truth and the arguments for and against the view, together with how the debate relates to other questions in philosophy.
