Modal realism is the view that the actual and the non-actual are equally real. It contrasts with actualism, the view that fundamental reality is restricted to actuality. Extended modal realism, as developed by Takashi Yagisawa, differs from other versions of modal realism, such as David Lewis' views, in several important aspects. Possible worlds are conceived as points or indices of the modal dimension rather than as isolated space-time structures. Regular objects are extended not only in the spatial and the temporal dimensions but also in the modal dimension: some of their parts belong to non-actual worlds. Among these non-actual worlds within the modal dimension are not just possible worlds but also impossible worlds. There is only one universe encompassing everything that is real in the
