  • Coincidence and modality 

    Kang, Li (University of St Andrews, 2011) - Thesis
    How should we understand de re modal features of objects, if there are such features? Any answer to the question is connected to how we should think about coincident objects, objects which occupy the same spatio-temporal ...
