Sortal Predication and Identity over time

Wednesday 27 February 2019, 4.00PM to 5:30pm

Speaker(s): Professor Thomas Mueller, Universitat Konstanz

My recipe for making "leaf to root" pesto instructs me to put a whole medium-size basil plant in the blender. If I push the button, do I destroy what is in the blender? Yes and no. Yes: the living basil plant is shredded to pieces and thereby ceases to exist. No: the ingredient for my pesto continues to exist and just undergoes a change of texture. Now, clearly, one and the same thing cannot both cease to exist and continue to exist at the same time. But I certainly put only one thing into the blender, not two. 

The above description of what goes on in my kitchen appears to be inconsistent; we have all the ingredients for a paradox. Is there a way to maintain consistency? In my talk, I will sketch a formal framework, case-intensional first order logic (Belnap & Müller, J Phil Logic 2014), that provides the resources for avoiding inconsistency while (I hope) making good sense of our assumptions. I will introduce the framework in an application to physics (regarding the Second Law of thermodynamics) before reverting to the original biological example. I will end with some speculations about reductionism.
