Author’s Abstract

  1. Murray MacBeath, in his essay "MacBeath (Murray) - Time's Square", describes a fictitious scenario where various physical observations made by the participants would, he claims, invite the interpretation that time for them is two-dimensional.
  2. In the present paper, however, I argue that such observations come close to underdetermining the hypothesis of time's two dimensionality; for a rival hypothesis - that, under certain circumstances, the observations can be explained in terms of the familiar time dilation effects predicted by special relativity - almost fits the evidence as well.
  3. That is, under certain (albeit artificial) circumstances world can already behave almost as though it were temporally two-dimensional.
