    Peter Railton (Michigan): First Steps Toward an Epistemology of Intuition in Ethics

    Abstract:  Appeals to intuition and intuitions have figured in philosophy at least since Socrates, and in the intervening millennia intuition and intuitions have been put to use for a variety of philosophical purposes, especially, in order to escape worries about regress in perception, thought, and action.  Today, the method of appealing to intuitions in thought experiments has become central to many areas of philosophy—though there has been some dissent over...

    Harvard Logic Colloquium: Theodore Slaman

    4:00pm to 6:00pm


    Logic Center, Room 420, 2 Arrow Street

    Theodore A. Slaman (University of California Berkeley): Recursion Theory and Diophantine Approximation

    Recursion Theory deals with the definability of sets, especially sets of natural numbers or equivalently
    real numbers. Diophantine Approximation deals with the approximation of real numbers by rational
    numbers, which can be viewed as a number theoretic form of definability. We will discuss connections
    between these areas.

    Harvard Logic Colloquium: Joel Hamkins

    4:00pm to 5:00pm


    Logic Center, Room 420, 2 Arrow Street

    Joel Hamkins (City University of New York): Recent Advances in Set-theoretic Geology

    Set-theoretic geology is the study of the set-theoretic universe V in the context of all its ground models and those of its forcing extensions. For example, a bedrock of the universe is a minimal ground model of it and the mantle is the intersection of all grounds. In this talk, I shall explain some recent advances, including especially the breakthrough result of Toshimichi Usuba, who proved the strong downward directed grounds hypothesis: for any set-indexed family of...
