The Perception of Time in Intuitionistic Arithmetic (Vincent Peluce)

The Logic and Metaphysics Workshop will meet on May 20th from 4:15-6:15 in room 7314 of the CUNY Graduate Center for a talk by Vincent Peluce (CUNY).

Title: The Perception of Time in Intuitionistic Arithmetic

AbstractIn L.E.J. Brouwer’s first act of intuitionism, the subject’s perception of time is put forth as the foundation on which arithmetic will be built. According to Brouwer, proper intuitionistic arithmetic, as with the rest of intuitionistic mathematics, is not tied to any particular formal system. When we try to axiomatically approximate an intuitionistic arithmetical system, we are faced with the problem of incorporating the subject and their perception into the axiom system itself. We discuss some unsatisfactory responses to this problem and then offer a solution.

Composition as Identity: A New Approach (Martina Botti)

The Logic and Metaphysics Workshop will meet on May 13th from 4:15-6:15 in room 7314 of the CUNY Graduate Center for a talk by Martina Botti (Columbia).

Title: Composition as Identity: A New Approach

AbstractI argue that the debate on composition as identity – the thesis that any composite object is identical to its parts – is deadlocked because both the defenders and the detractors of the claim have so far defended and criticized respectively something that is not composition as identity. After having made clear how composition as identity should properly be understood, I will set forth a new strategy to defend it.
