Given substantivalism (and a sensible, flexible theory of de re <a name="2"></a><A HREF="../../Notes/Notes_1/Notes_121.htm">modal</A><SUP>2</SUP> predication), one might as well identify continuants with regions of space-time, which have temporal parts. Alternatively, one could identify continuants with instantaneous slices of space-time and employ temporal counterpart theory; either way, we have a four-dimensionalist metaphysics of continuants. On the other hand, relationalism about space-time cannot be made to work without temporal parts. So either way, we have an argument for four-dimensionalism. </li><li>It can never be vague how many objects exist; if temporal parts do not exist then a restrictive account of which filled regions of space-time contain objects must be given; but no such account can be given that is plausible and non-vague. </li></ol> </li></ul></FONT><BR><U>Sections</U><FONT COLOR = "800080"><ol type="1"><li>Russell's argument from parsimony  75</li><li>The argument from logic  76</li><li>The A-theory of time is incoherent  78</li><li>Four-dimensionalism and special relativity  79</li><li>Space and time are analogous  87</li><li>The problem of temporary intrinsics  92</li><li>Arguments from exotica  98</li><li>The argument from spacetime  110</li><li>The argument from vagueness  120 </li></ol></FONT><FONT COLOR = "0000FF"><HR></P><a name="ColourConventions"></a><p><b>Text Colour Conventions (see <A HREF="../../Notes/Notes_10/Notes_1025.htm">disclaimer</a>)</b></p><OL TYPE="1"><LI><FONT COLOR = "0000FF">Blue</FONT>: Text by me; &copy; Theo Todman, 2018</li><LI><FONT COLOR = "800080">Mauve</FONT>: Text by correspondent(s) or other author(s); &copy; the author(s)</li></OL> <BR><HR><BR><CENTER> <TABLE class = "Bridge" WIDTH=950> <TR><TD WIDTH="30%">&copy; Theo Todman, June 2007 - August 2018.</TD> <TD WIDTH="40%">Please address any comments on this page to <A HREF="mailto:theo@theotodman.com">theo@theotodman.com</A>.</TD> <TD WIDTH="30%">File output: <time datetime="2018-08-03T00:13" pubdate>03/08/2018 00:13:39</time> <br><A HREF="../../Notes/Notes_10/Notes_1010.htm">Website Maintenance Dashboard</A></TD></TR> <TD WIDTH="30%"><A HREF="#Top">Return to Top of this Page</A></TD> <TD WIDTH="40%"><A HREF="../../Notes/Notes_11/Notes_1140.htm">Return to Theo Todman's Philosophy Page</A></TD> <TD WIDTH="30%"><A HREF="../../index.htm">Return to Theo Todman's Home Page</A></TD> </TR></TABLE></CENTER><HR> </BODY> </HTML>
