 These distinctions will prove helpful in the subsequent discussion of becoming in modern physics. For the moment, one might note that Broad could argue that McTaggart’s (A1) seems plausible if the copula is understood in some tenseless fashion, whereas (A2) is plausible if the copula is tensed. If, however, the copula is not univocal in (A1) and (A2), then there is no contradiction involved in accepting both (Savitt, 2001).
