Two open-ended cosmological argument

First argument:

  1. There are no infinite causal regresses or causal loops.

  2. Every ordinary entity has a cause.

  3. So, there is an extraordinary entity.

Second argument:

  1. There is a causal explanation why there are any ordinary entities.

  2. Causal explanations are not circular.

  3. So, there is an extraordinary entity.

Yet another counterexample to Nicod's Principle

Nicod’s Principle says that the claim that all Fs are Gs is confirmed by each instance.

Here’s yet another counterexample. Consider the claim:

  1. All unicorns are male.

We take this claim to be true, albeit vacuously so, since there are no unicorns.

But suppose an instance of (1), namely a male unicorn, were found. We would immediately conclude that (1) is probably false. For if there is a male unicorn, likely there is a female one as well.

The problem here is that when we learn of Sam that it is a male unicorn, we also learn that there are unicorns. And as soon as we learned that there are unicorns, that undercut the reason we had for believing (1), namely that we thought (1) was vacuously true.

Slavery, forced marriage and unjust laws

Slavery is the ownership of one person by another. Since a person no more owns another than a thief owns the purloined goods, there has never been any slavery. But of course there have been institutions thought to be slavery: institutions in which a person was thought to be the property of another. These were not institutions of slavery in the above strict sense but forms of unjust imprisonment, kidnapping, etc.

This seems to be merely a point about words, and a mistaken one at that. “Of course, Alexander II ended serfdom in Russia while Lincoln ended slavery in the US. Words mean what they are used to mean, and to dispute historical claims like these is to be like the fusty grammarian who claims that ‘It’s me’ is bad English.”

I agree that the question of words is unimportant. But here is what is important. Institutions are defined in large part by their norms. It is a defining feature of the norms of slavery (and, with some differences, of serfdom) that one person has property-style rights over another who has onerous obligations corresponding to these rights. But in fact, nobody has such rights over another, and the supposed obligations do not obtain. The institution that the “masters” saw themselves as a part of did not in fact exist, because the rights and obligations that they took to be integral to the institution did not, and could not, in fact exist.

We can use the term “slavery” (and cognates in other languages) for that non-existent institution, just as we use the term “phlogiston” for the substance that chemists mistakenly believed in before oxygen was discovered.

But we could also use distinguish and use two terms. Maybe slaveryh is the historical form of social organization that actually (and deplorably) existed and slaveryn is the normative institution that the mastersh (and maybe some of the slavesh, as well) incorrectly thought to exist and thought to be coextensive with slaveryh.

Again, the words don’t matter, but it matters that there was a morally condemnable attempt to create a certain social institution which attempt failed because the norms that were attempted to be instituted were incapable of institution.

This is a pattern we find in many other cases. There is no such thing as a forced marriage, since the norms of love and sexuality that define marriage do not come into existence apart from the free consent of the parties. But of course over the course of history there have been morally condemnable attempts to force people—especially women—into the institution of marriage. These attempts always failed, and what the victims were forced into was a different institution, one subjecting them to such injustices as kidnapping, unjust imprisonment, rape, etc.

Thomas Aquinas, similarly, holds that there are no unjust laws. Of course, legislators may attempt to enact laws that would be unjust (or they may simply be exercising power and not even trying to legislate). But when they do so, they fail to enact laws. What they enact are mere demands masquarading as laws (philosophical anarchists think all “laws” are like that). Again, the question of words is unimportant, but what is important is the pattern: the legislator is deplorably attempting to create a social institution—a law—and failing to do so, but instead creating another institution.

The particular cases of this pattern are interesting, and so is the pattern itself. A central part of the pattern is an attempt to create an institution (or an instance of an institution) that misfires, and instead another institution is created that is widely but mistakenly thought to be the one that was the target of the attempt. But the cases of slavery, forced marriage and unjust laws also share another feature that not all the cases of misfiring do. For instance, suppose due to an honest mistake in the counting of ballots, there is a mistake as to who the mayor of a town is. The false mayor then attempts to legislate something quite just. The attempt fails, because the false mayor lacks the standing to legislate. But there need be nothing morally deplorable here, as there is in the slavery, forced marriage and unjust law cases.

Moreover, the three cases I started with are not just morally deplorable, but there seems to be an important connection between moral evil and performative misfire. Slaveryh is morally horrific, but slaveryn would be even worse, as the slavesn would be under genuine obligations to do the enforced labor required of them and not to escape. This would, as it were, make morality itself complicit with the master, and the properly formed conscience of the slave into a whip in the master’s hand. And the same holds in the other two cases: morality itself would be a tool of oppression.

There are, alas, times when morality is a tool of oppression. The duties that exist between relatives are frequently exploited by repressive regimes as a means of social control: If you are an Uyghur or Tibetan defecting to a free country and speaking out against the Chinese regime, your relatives back home will suffer, and this restricts your activity because of the duties you have to your relatives. But the kinds of cases where the wicked use morality as a lever against the righteous seem different and less direct from what would be the case if slavery, forced marriage and unjust laws had the normative force that they pretend to. It is a mere coincidental effect of duties to family when these duties make it morally impossible or difficult to stand up to a wicked regime. But it would be of the very nature of the norms induced by slavery, forced marriage and unjust laws—if these norms really came into existence—that they would oppress.

This still leaves an interesting puzzle, which different moral theories will answer differently: Why is it the case that morality does not innately oppress?

Objection: Maybe slaveryh does create norms, but not moral norms.

Response: I myself don’t think there are any non-moral norms. But in any case slaveryh does not create any kind of obligation on the slave to obey the master, whether moral or not, except in some, but not all, cases a prudential one.

The search for new truths

I know that I have two hands. With a bit of thought, I now know a number of truths that it seems no ordinary person has ever known before:

  • I have two hands or there is a palomino painted green and pink with someone in a Darth Vader costume on its back.

  • I have two hands or the number of pigs born in 1745 is odd.

  • I have two hands or Sir Patrick Stewart will consume a prime number of calories tomorrow.

  • I have two hands or Donald Trump issued a series of anti-Klingon tweets yesterday.

And so on, ad infinitum. The search for new truths is thus really easy. I just need to search for silly propositions that no one has thought about, and disjoin them with something I know.

External time as such doesn't matter to us

Suppose a deity threatened to move us all to a universe where everything is pretty much as in our world, except that electric charges are reversed and the laws of nature are tweaked to ensure that this reverse doesn’t affect our lives. Thus, in that world, we are based not on carbon atoms, but on anti-carbon anti-atoms (they will have six anti-protons and six positrons, etc.), but the laws are tweaked so that the anti-atoms would behave just like atoms.

Assuming we can survive the shift, it seems that except for sentimental considerations (maybe when Grandma’s old wedding ring is replaced by a ring of anti-gold, it’s no longer the same ring) it would make no difference to us.

Similarly, if the deity threatened to spatially rotate the world by 180 degrees around some axis, that would make no difference to us.

What if the deity offered to rotate our world in time by 180 degrees, with causation now running temporally backwards, with us being born in the future and dying in the past, but everything being kept intact. It seems to me that this would make no difference to us.

Similarly, it seems to me that if the deity offered to rotate our four-dimensional world so that the temporal dimension and a spatial dimension were swapped, so that we would be born and die at the same time, but in different places along a spatial axis, and causation would run unidirectionally along the spatial axis, again that would make no difference to us.

I think these thought experiments suggest that external time as such is not important. What matters is how the distribution of things interacts with the causal order.

To be honest, though, I am not completely confident that any of these thought experiments make sense. It could be that any dimension along which causation runs much as causation runs along the temporal direction in our world is therefore a time dimension. But if so, then I think it's still true that it is causation, not external time as such, that matters.

I am less confident of this in the case of internal time.

Disembodied trees

Here’s an interesting thesis:

  1. If x has the ys among its parts, and for each z among the ys, x can survive losing z without gaining anything, then x can survive simultaneously losing all the ys without gaining anything.

There are obvious apparent counterexamples. A boat that has sufficient redundancy can survive the loss of any plank, but cannot survive losing them all. An oak tree can lose any cell but cannot lose all cells.

But counterexamples aside, wouldn’t (1) be a nice metaphysical thesis to have? Then essential parts wouldn’t be made of inessential ones. You can see all the nasty ship-of-Theseus questions that would disappear if we had (1).

I think an Aristotelian can embrace (1), and can get around the counterexamples by biting some big bullets. First, like some contemporary Aristotelians, she can deny that artifacts like boats (or bullets) exist. Second, she can say that oak trees can survive the loss of all their matter, becoming constituted by form alone, much as some philosophers say happens to human beings after death (before the resurrection). The second part seems a bigger bullet to bite, as one would need a story as to why in fact oak trees perish when they lose all their cells, even if they don’t have to. But perhaps that’s just contingently how it happens, though an all powerful being could make an oak tree survive the destruction of all its cells.

The big question here is exactly what philosophical advantages embracing (1) has.

Distinguishing between properties

Some philosophers worry about “principles of individuation” that make two things of one kind be different from another. Suppose we share that worry. Then we should be worried about Platonism. For it is very hard to say what make two fundamental Platonic entities of the same sort different, say being positively charged from being negatively charged, or saltiness from sweetness.

However, the light-weight Platonist, who denies that predication is to be grounded in possession of universals, has a nice story to tell about the above kinds of cases. For here is a qualitative difference between saltiness and sweetness:

  • saltiness is necessarily had by all and only salty things, but

  • sweetness is not necessarily had by all and only salty things.

But for the heavy-weight Platonist to tell this story would involve circularity, for what it is for a thing to be salty will be to exemplify saltiness.

Of course, this story only works for properties that aren’t necessarily coextensive. But it’s some progress.

Acting without existing (any more)

Thesis: It is possible for an object to be acting while it does not exist.

Argument:

Imagine a rattlesnake that is ten light-years long, all stretched out. For all one hundred years of life it has been deliberately rattling its rattle. And then at the end of its hundred years, its head is destroyed, and I assume that the destruction of the head of a snake is sufficient for its death.

Rattling continues for at least about ten years even after the snake is dead, since the nerve signals the brain had sent while the snake was alive are continuing to rattle.

If this post-mortem rattle counts as the snake’s activity, the Thesis is established. But it is not clear that this ten years of post-mortem rattle is the snake’s activity.

But now consider the last year of pre-mortem rattling, call it R99 (since it starts in year 99 of the snake’s life). Whatever one says of the post-mortem rattling, clearly R99 is the snake’s activity. However, there is a reference frame—the way I set the length of the snake and the times in the story guarantees this—in which R99 occurs after the snake’s head has been destroyed, and hence occurs after the death of the snake. But R99 is the snake’s activity. Hence, there is a reference frame where an activity of the snake occurs after the snake is dead.

Scholium:

Obviously, only existent things can act. But while existence simpliciter is important for activity, existence-at-a-time does not have the same kind of significance. Obviously, often an actor’s action has a relationship R to some thing x that the actor itself does not have. For instance, an agent’s action may be known by me without the agent being known by me (here, R is being known and x is me).

Now, when we say that Elizabeth II exists as Queen of Canada, that is just an awkward way of saying that she has a monarchic relationship to Canada, rather than being a claim about that mysterious thing deep ontology studies: existence. I think we should think of existing-at-a-time as not really existence but simply as a particular kind of relationship—an occupation or presence relationship. It is not surprising in general that activities can stand in relationships that the agents do not. So, why can’t an activity stand in an occupation relationship to a time that the agent does not?

I think much confusion in philosophy comes from thinking of existence-at-a-time and existence-in-a-place as something special, somehow deeply ontologically different from other relations.
