Four Dimensionalism

Abstract In a recent article, Ned Markosian gives an argument against four-dimensionalism understood as the view that time is one of four similar dimensions that constitute a single four-dimensional manifold. In this paper, I show that Markosian attacks a straw man as his argument targets a theory known to be false on empirical grounds. Four-dimensionalism rightly conceived in no way entails that time is identical to space. I then address two objections raised by Markosian against four-dimensionalism rightly conceived.

The Absolute

In a recent article in this journal, Barbara Lariviere offers a very useful distinction between two ways of understanding the claims that Leibniz, or relational theorists in general, might wish to make about the nature of motion and the structure of space and time; viz.,(L1) There is no real inertial structure to space-time.and(L2) There is a real inertial structure to space-time, but it is dynamical rather than absolute.Citing the authority of Weyl, the author argues that L1 is untenable; indeed, the argument purports to show that if L1 were true, then there would be no coherent basis for a theory of motion, not even a relational theory. My main goal in this note is to point out why this argument is mistaken while at the same time sketching the real reason why the relational conception of motion is untenable. In addition I will offer a few remarks about the relevance of L2 to the absolute-relational controvery.

Flow Of Time

The question used as the title of this article has been asked frequently since the introduction of space–time in which both space and time function as coordinates in a four-dimensional manifold. After a brief review of space–time geometry using the affine bundle it is shown how to construct it from a bundle of linear frames of a five-dimensional manifold. The flow of time is a consequence of the construction.

Spacetime Theory

Spacetime is the four-dimensional manifold proposed by current physics as the arena for Nature’s show. Although Newtonian physics can very well be reformulated in a spacetime setting, the idea of spacetime was not developed until the twentieth century, in connection with Einstein’s theories of special and general relativity. Due to the success of special relativity in microphysics and of general relativity in astronomy and cosmology, every advanced physical theory is now a spacetime theory. Spacetime is undoubtedly an artificial concept, which our hominid ancestors did not possess, but the same is true of Newtonian space and time.
