I said that one way of thinking about the Ship of Theseus is to reflect that in this case these two tests point to different conclusions. Spatiotemporal continuity , then, is a criterion of identity on which I rely for most of my judgments of identity. Is it a metaphysically sufficient condition for the persistence of an object? Obviously not; a tree can burn until it is just a pile of ash, though there were no leaps through space or time.The use of a continuous model for spatio-temporal modeling in the context of this work is a formulation very distinct of the usual models based on discrete specifications using lattice structures. However, the use of a lattice structure in the current problem has some limitations. The first important limitation is the fact that the spatial data ...A constant-local-group spatio-temporal box (CLG-ST-box) is a To define the continuity relation between envelopes, we first de- temporal sub-division of an ST-box, over which it is a member of fine a successor relation Suc(E1 , E2 ) ≡def ((e(E1 ) + 1) = a constant local group.
