gives a detailed discussion, with precedents, of the present as a spacelike hypersurface. It explains why Feynman's time reversal, Malament's theorm about the Lorentz transformation, and tachyons are irrelevant to this, and shows where the present might be in a black hole. The paper also deals with the problem of how the present advances, by introducing something like a computer program running in the before/after order of happening, rather than in the earlier/later order of time coordinates. The program refers to the “highest agent”.

is a very brief further explanation (a) clarifying that RP always means ‘reinterpretation principle’, and (b) mentioning that the idea of the present as a spacelike hypersurface was used by Fred & Geoffrey Hoyle in their 1963 science fiction novel Fifth Planet (London: Heinemann) - see the Preface, p. vii. It omitted to say that Hoyle & Hoyle suggested only that spacelike hypersufaces could give a subjective (and perhaps merely local) present. In fact, the idea works equally well for an objective, universal present. This Erratum is also in Part 1 of its volume.
The development of these ideas culminates, for the moment, in God & Time II (2008). Intermediate provisional ideas occur in other papers on this site.
