Unlike Cameron, I think that The Block Universe Theory of Time is true, but like Cameron I’ve argued that the best alternative, the theory it should be squaring off against in the World Series of The Philosophy of Time, is The Moving Spotlight Theory. I came to Cameron’s book, therefore, curious about how his argument for this claim was going to go.1...Parts of the book really opened my eyes. I’m thinking especially of Cameron’s discussion of the argument that the presentist can, while the moving spotlight theorist cannot, accept the claim that they know that they are...

But I don’t think they are defective; and what Cameron says is missing from these theories is actually present in a version of MST-Time that appears in the book.Cameron thinks that MST-Supertime, to start with, is inconsistent, and so the worst of the lot. He thinks McTaggart’s argument shows it to be inconsistent. But the theory is not inconsistent. We can draw a picture of what reality is like according to the theory, and the picture doesn’t confuse us the way M. C. Escher's pictures of inconsistent situations do. Figure 1 contains such a picture: the arrows...

What does the passage of time consist in? There are some suggestive metaphors. âEvents approach us, pass us, and recede from us, like sticks and leaves floating on the river of time.â âWe are moving from the past into the future, like ships sailing into an unknown ocean.â There is surely something right and deep about these metaphors. But how close are they to the literal truth? In this book Bradford Skow argues that they are far from the literal truth. Skowâs argument takes the form of a defense of the block universe theory of time, a theory that, in many ways, treats time as a dimension of reality that closely resembles the three dimensions of space. Opposed to the block universe theory of time are theories that take the metaphors more seriously: presentism, the moving spotlight theory, the growing block theory, and the branching time theory. These are theories of ârobustâ passage of time, or âobjective becoming.â Skow argues that the best of these theories, the block universe theoryâs most worthy opponent, is the moving spotlight theory, the theory that says that âpresentnessâ moves along the series of times from the past into the future. Skow defends the moving spotlight theory against the objection that it is inconsistent, and the objection that it cannot answer the question of how fast time passes. He also defends it against the objection that it is incompatible with Einsteinâs theory of relativity. Skow proposes several ways in which the moving spotlight theory may be made compatible with the theory of relativity. Still, this book is ultimately a defense of the block universe theory, not of the moving spotlight theory. Skow holds that the best arguments against the block universe theory, and for the moving spotlight theory, start from the idea that, somehow, the passage of time is given to us in experience. Skow discusses several different arguments that start from this idea, and argues that they all fail.

It is widely accepted that readers will resist imagining that a character in a story did something morally wrong, even if the story endorses this judgement. This paper argues, first, that readers will not resist if the question of whether that act was wrong is not salient as they read; and, second, that asking a certain question can be part of correctly appreciating a story—even if that question is not in the foreground of the story, and even if the story itself discourages readers from asking it, as is common in some forms of the ‘hermeneutics of suspicion’.

Sometimes, a proposition is fictional in a story in virtue of the fact that other fictional truths are good evidence for it. Cases are presented in which this evidential rule, and not some rule that invokes counterfactuals or intentions, is what explains what is fictional. Applications are made to the question of interpretive pluralism and the problem of imaginative resistance. In the background is pluralism about fictionality: the evidential rule is one of a variety of rules that are needed to account for what is fictional in a story.

Bohmian mechanics faces an underdetermination problem: when it comes to solving the measurement problem, alternatives to the Bohmian guidance equa- tion work just as well as the official guidance equation. Dürr, Goldstein, and Zanghì have argued that of the candidate guidance equations, the official guid- ance equation is the simplest Galilean-invariant candidate. This symmetry argument—if it worked—would solve the underdetermination problem. But the argument does not work. It fails because it rests on assumptions about how Galilean transformations act on the wavefunction that are unwarranted. My discussion has larger morals about the phys- ical significance of certain mathematical results in non-orthodox interpretations of quantum mechanics.

In lieu of an abstract, here is a brief excerpt of the content:Groll on Bionormativity and the Value of Genetic KnowledgeBradford Skow (bio)1. IntroductionShould people who plan to use donated sperm and/or eggs to conceive a child use an open donor who agrees ahead of time that any resulting children may be told who the donor is? In Conceiving People: Genetic Knowledge and the Ethics of Sperm and Egg Donation (Groll 2021), Daniel Groll answers yes. He argues that using an anonymous donor would be wrong. Groll does not discuss adoption in detail, but his ideas also support the claim that people who adopt a child should adopt from parents who agree ahead of time that their child may be told who their biological parents are. It is not OK to have a closed adoption, in which information about the child's biological parents that would otherwise be public (for example, information on their original birth certificate) is kept secret by the government, and where (in some cases) the biological parents are promised that their children will never learn who they are. I was adopted in a closed adoption and met my biological family when I was twenty, and I think Groll's answer to his main question is right. That, however, does not mean I agree with all of his reasons. Here I examine those reasons and sketch some places where I would depart from them.2. The argument in outlineThe basic outline of Groll's argument, in simple terms, is as follows.1. If a child's knowing who their genetic parents are will likely benefit them—that is, if it will make their life go better, or increase their wellbeing—and if this is foreseeable, then that is a reason for parents to make the child's learning this possible (at some "appropriate" time).2. That knowledge will likely benefit the child …3.. … and this is foreseeable. [End Page 182]4. This reason favoring parents making genetic knowledge possible is strong enough that, except in maybe very special circumstances, parents should make this knowledge possible.The first point is hard to dispute. If the second point is true, then the third point is also plausible, since it is foreseeable that a child born from gamete donation (or an adopted child) will likely try to learn who their genetic (or biological) parents are. These searches are common and widely known to occur. Most of the action, therefore, is in the second point. Why think that knowing who your genetic or biological parents are is likely to make your life go better? Here the path diverges into a wood.3. First try: getting what you want makes your life go betterThe simplest way to argue that knowing who your genetic parents are is a benefit is to note that many, if not most, people conceived through gamete donation (or adoption) will, at some point, want—intensely want—to know who their genetic (or biological) parents are. One can then appeal to the idea that getting what you want makes your life go better, other things being equal.1Groll does not like this justification. His objection is that it does not show "that there is anything resembling a deep connection between genetic knowledge and well-being" (Groll 2021, 65). On Groll's view, knowing who your genetic (biological) parents are is a benefit, but this is not simply because it is something you want to know. I might know ahead of time that my child will want to live in a red house, and they might therefore be better off if they get to, and I might do my best to make that possible; but the reason I have to make genetic knowledge available to them is much stronger and much weightier than my reason to help them live in the right colored house. (It may be that this is where the fourth point of the argument, about the strength of reasons, comes in.)So why is the reason to provide genetic knowledge stronger? Groll, I think, holds that some things are more worth wanting than others. Getting what you want may benefit you, but getting what you want when what you want is something...

Is double prevention causation? Some say yes and some say no, but the answer is yes and no. Interrupting double prevention, where A prevents B from continuing to prevent something, is causation, while blocking double prevention, where A intervenes before B has begun preventing anything, is not. I present two arguments for this thesis. First, it sorts canonical examples of double prevention correctly. Second, well-known theoretical arguments that double prevention is not causation only show that blocking double prevention is not causation.

Iconoclasts and gadflies might deny it, but they’re just looking for negative attention. It is therefore frustrating to be told, as I have been, that one's theory of time is false because it leaves out the passage of time. In a way, Objective Becoming is a defence of the theory I prefer against this accusation. That theory is the block universe theory of time.1...The bumper-sticker version of the block universe theory says that time is a dimension of reality that is a lot like space. Since space does not move, or flow, neither does time. But that’s okay; time does not need to move or flow in order for it...
