ABSTRACT
No mention has yet been made of the Special Theory of Relativity (STR) and as this theory is popularly supposed to embody a radical challenge to our ordinary concepts of space and time this lacuna must now be filled. Interestingly, all that is required in order to pass from this slender basis to the Lorentz transformations which are the heart of the STR is a further causal postulate which is arguably a largely conceptual constraint. The conceptual element in this causal postulate is the claim that if there is a relation of causal connectibility holding between a pair of events, that relation holds regardless of the frame of reference in terms of which the events are described. From the representation of the STR given above, we can see that the theory has no implications for the issue of the topological structure of time.
