This paper investigates the question whether we could have reason to believe that time is two-dimensional. I connect discussion of this question to discussion of the question whether we could have reason to believe that there has been a global time freeze.

There is sufficient evidence at present to justify the belief that the universe began to exist without being caused to do so. This evidence includes the Hawking-Penrose singularity theorems that are based on Einstein's General Theory of Relativity, and the recently introduced Quantum Cosmological Models of the early universe. The singularity theorems lead to an explication of the beginning of the universe that involves the notion of a Big Bang singularity, and the Quantum Cosmological Models represent the beginning largely in (...) terms of the notion of a vacuum fluctuation. Theories that represent the universe as infinitely old or as caused to begin are shown to be at odds with or at least unsupported by these and other current cosmological notions. (shrink)

In the Western theist tradition, the conception of a person tends to be understood as an intrinsic property. Hence, the classification of someone as a person does not depend on relational aspects of that person. From this, Western theists often understand that their conception of God as a person does not clash with the idea of immutability. In this article, I challenge the idea that being a person and being immutable are compatible properties by using Afro-communitarian philosophy and, more specifically (...) Afro-communitarian metaphysics of personhood. Afro-communitarian metaphysics is fundamentally relational, i.e. it understands that most properties of the world depend on the existence of other entities. More precisely, personhood is a property that depends on the existence of relatable beings. But if this is true, then it is not possible to hold that an entity that has the property of personhood also has the property of immutability. More specifically, an entity that is a person has to change due to the fact that personhood is a relational property. This is because it is a necessary condition for being a person that one relates to others, i.e. one only becomes a person when this relation occurs. Hence, the process of becoming a person requires a moment before the relation with another and one after; thereby, the feature of being a person requires the feature of change. With respect to the Christian conception of God, what this implies is that if theist philosophers wish to understand Him as a person, they have to also accept that God is not immutable. For if other beings besides Him are not eternal, then it is only possible that He can be a person when these other beings first started existing. This is the case because the kind of relationality needed to be a person is not simply to relate to something (like emptiness), but to do something that makes Him addressable (which requires that the thing He relates to has the capacity to address Him). This means there are two moments of existence where He has distinct properties and, therefore, is mutable. (shrink)

Bei der Renaissance der philosophischen Auseinandersetzung mit Fragen über Gott spielte der Oxforder Philosoph Richard Swinburne eine wesentliche Rolle. Er kann als der bedeutendste zeitgenössische Vertreter der natürlichen Theologie gelten. Natürliche Theologie ist das Unternehmen, philosophisch zu untersuchen, ob es einen Gott gibt und wie er beschaffen ist. Dies ›philosophisch‹ und nicht theologisch zu untersuchen, heißt, direkte Offenbarung dabei nicht als Erkenntnisquelle zu verwenden.

Recently, JT Turner has argued that proponents of temporally-extended models of purgatory are committed to denying the doctrine of the parousia. Such persons typically argue that temporally-extended models of purgatory are needed to prevent the possibility that a morally imperfect human might become morally perfect too abruptly. In this article, I argue that Turner is mistaken and that by invoking hypertime and a clarification of the sort of abruptness at issue, temps can affirm both purgatory and the doctrine of the (...) parousia. After clarifying the nature of hypertime, I then present a non-temporal model of purgatory. This model permits those uncomfortable with endorsing the metaphysical possibility of hypertime to nevertheless affirm the key intuition motivating temporally-extended models without rejecting the doctrine of the parousia.

Van Bendegem has recently offered an argument to the effect that, if time is discrete, then there should exist a correspondence between the motions of massive bodies and a discrete geometry. On this basis, he concludes that, even if space is continuous, it should nonetheless appear discrete. This paper examines the two possible ways of making sense of that correspondence, and shows that in neither case van Bendegem’s conclusion logically follows.

This essay examines some of the arguments in David Deutsch's book The Fabric of Reality , chief among them its case for the so-called many-universe interpretation of quantum mechanics (QM), presented as the only physically and logically consistent solution to the QM paradoxes of wave/particle dualism, remote simultaneous interaction, the observer-induced 'collapse of the wave-packet', etc. The hypothesis assumes that all possible outcomes are realized in every such momentary 'collapse', since the observer splits off into so many parallel, coexisting, but (...) epistemically non-interaccessible 'worlds' whose subsequent branchings constitute the lifeline-or experiential world-series- for each of those proliferating centres of consciousness. Although Deutsch concedes that his 'multiverse' theory is counter-intuitive, he none the less takes it to be borne out beyond question by the sheer observational/predictive success of QM and the conceptual dilemmas that supposedly arise with alternative (single-universe) accounts. Moreover, he claims the theory resolves a range of longstanding philosophical problems, notably those of mind/body dualism, the various traditional paradoxes of time, and the freewill/determinism issue. The essay suggests on the contrary, that Deutsch unwittingly transposes into the framework of presentday quantum debate speculative themes from the history of rationalist metaphysics, often with bizarre or philosophically dubious results, and that he rules out at least one promising rival account, namely Bohm's 'hidden variables' theory. It goes on to consider reasons for resistance to that theory among proponents of the 'orthodox' (Copenhagen) doctrine, and for the strong anti-realist, at times even irrationalist bias that has characterized much of this discussion since Bohr's debates with Einstein about quantum non-locality, observer-intervention, and the limits of precise measurement. Finally, the contrast is pointed out between Deutsch's ontologically extravagant use of the many-worlds hypothesis (akin to certain ideas advanced by speculative metaphysicians from Leibniz down) and those realist modes of counterfactual reasoning- e.g. in Kripke and the early Putnam- which deploy similar arguments to very different causal-explanatory ends.
