Perdurantism and Replacement Theory Essay Sample

The difference between perdurantism and replacing theory is located in the apprehension of the related constructs of individuality. alteration. and clip. In many ways it is the 1 of the oldest statements in doctrine dressed up in Einsteinian pretense. Perdurantism holds that an object must be conceived of in a unitary mode bing as a whole which extends in the traditional spacial dimensions and throughout the object’s temporal being. That is. in a manner that respects the sphere of space-time. In perdurantism individuality is understood “in the rigorous mathematical sense of being one and the same object” ( Heller. 1992. p. 697 ) . Change. which needfully invokes the temporal. is manifested by the finiteness of perceptual experience ; in perdurantism we do non see an object but simply a spatio-temporal portion of an object. A portion of the object may hold a belongings which has less temporal continuance that the object itself. Therefore. the object does non alter. we simply perceive different parts of it. In Heller’s position. “our perceptual experience along the temporal dimension is merely one directional” ( Heller. 1984. p. 326 ) . Change is a consequence of that way.

Replacement theory understands change non as a different portion of a perduring 4-dimensional object. instead an object is swapped out by a really similar object. The metaphor is that of a film ( Heller. 1992. p. 699 ) . Our perceptual experience sees uninterrupted gesture due to continuity of vision yet we are shown 30 distinguishable images per second. This is to state replacing theory understands individuality in astation factosense. We understand individuality by roll uping the similar objects under one sense.
