We explore the role of episodic imagining in explaining why people both differentially report that it seems to them in experience as though time robustly passes, and why they differentially report that they believe that time does in fact robustly pass. We empirically investigate two hypotheses, the differential vividness hypothesis, and the mental time travel hypothesis. According to each of these, the degree to which people vividly episodically imagine past/future states of affairs influences their tendency to report that it seems to them as though time robustly passes and to judge that time does robustly pass. According to the former, a greater degree of vividness will tend to increase the extent to which people make such reports, while according to the latter, it will tend to decrease the extent to which people make such reports. We found weak evidence in favour of the former hypothesis. We reflect on the implications of this finding for theorising about such reports.

Several philosophers have suggested that certain aspects of people’s experience of agency partly explains why people tend to report that it seems to them, in perceptual experience, as though time robustly passes. In turn, it has been suggested that people come to believe that time robustly passes on the basis of its seeming to them in experience that it does. We argue that what require explaining is not just that people report that it seems to them as though time robustly passes, and that they believe that it does, but rather, the substantial variation (a) in people’s reports regarding whether it seems as though time robustly passes, and (b) their beliefs about whether time robustly passes. We empirically investigate the agentive explanation of (a), according to which variation in people’s agentive experiences explains variation in people’s reports regarding whether it seems to them as though time robustly passes. We also empirically investigate the experiential seeming explanation of belief, according to which variation in people’s beliefs about whether time robustly passes is explained by variation in their reports regarding whether it seems in experience as though time robustly passes. We found empirical support for the agentive explanation, but not for the experiential seeming explanation of passage beliefs. We consider the implications of our results for three views about temporal experience and temporal beliefs: dynamism, passage illusionism and deflationism.

In “The Open Future” (2021) Patrick Todd argues that the future is open, and that as a consequence all future contingents are false (as opposed to the more common view that they are neither true nor false). Very roughly, this latter claim is motivated by the idea that (a) presentism is true, and so future (and indeed past) things do not exist and (b) if future things do not exist, then the only thing that could ground there being future tensed facts, and hence make those future tensed claims true, is the present and the laws of nature. But (c) the present and the laws of nature cannot ground there being future tensed facts because they do not necessitate there being any such fact. Hence future tensed claims are all false. Todd then goes on to present a semantics for his version of the open future on which all future contingents are false. In what follows we take up two strands of Todd’s view. First, we begin, in Section 2, by outlining Todd’s argument that future contingents are all false. We suggest that the considerations that Todd adduces for this conclusion do not support this being so. Then in Section 3 we consider the semantics that Todd offers, and argue that it yields implausible consequences.
