One approach to time travel is to embrace timeline branching: when someone travels in time and changes something (which is inevitable), then a branch grows from the timeline. This, as was discussed in the previous essay, allows a possible solution to the grandfather paradox. But it also gives rise to various problems and questions, such as the need to account for the creation of a new universe for each timeline branch. The fact that these universes are populated also creates a problem, specifically one with personal identity. Since I used the grandfather paradox as the context previously, I will continue to do so.
Suppose that Sally and Ted travel back in time and Sally kills her grandfather Sam. Ted does not murder his grandfather. Assuming the timeline branching solution to the grandfather problem, Sally creates a new timeline branch in which Sam is killed. While Sally does not exist (one assumes) in the new timeline, Ted does. There would be at least two Teds now: one that is in the original timeline and the Ted in the new timeline. In fact, anyone who was alive for the creation of the new timeline would presumably also in the new timeline as the entire population of the universe would be replicated. This raises some obvious questions about how this would work and issues within the context of personal identity. For the sake of simplicity, I will focus on Ted as my example, but this would also apply to anyone who ends up being branched.
To keep it simple, let us suppose that Sally and Ted are the first time travelers, so there have been no time branches. When they travel back, they create the first branch. While Sally will not exist in the new branch (and her act of murder might result in other people not existing or even new people existing), Ted will exist in both. So how would this work?
One option is to take the time splitting metaphor literally: the universe and the people in it are split into two. Think of this as like an amoeba dividing. This does raise the obvious question of whether whatever makes a person the person they are can be split. For example, Leibniz took a person to be a monad, and his monads are metaphysically simple: they cannot be split. But if personal identity rests on something that can be split up, then this would be possible. For example, Hume (sort of) advances a bundle theory of personal identity. On his view, the self is not a simple, indivisible entity. It is a collection or bundle of perceptions. To use a metaphor, just as a bundle of marbles could be divided up, this bundle could also be divided between timelines. This would lead to questions about trans timeline identity: would there be one divided person or two people who arose from a past person? In the case of Ted, there would be one Ted in each timeline, and they might (or might not) be the same person.
Another option is that the people in the new timeline are identical duplicates. This would require that the basis of personal identity be something that can be copied. Locke, for example, makes consciousness (memory) the basis of personal identity and even considers a case in which a person’s consciousness (memory) is duplicated. With a basis of personal identity that can be copied, the problem is solved: each new timeline person is a copy of the original. This also leads to the question of whether they are a trans timeline person or multiple different people who happen to have originated from the same person. One obvious consideration is that the basis of personal identity is supposed to be what makes a person distinct from all other things and this suggests that there should only be one of each person. But this view can be countered by arguing that it is philosophically fine to have multiples of the same person. This could be reined in a bit by limiting it to one person per timeline, the challenge would be justifying and explaining this restriction. On this view, there would be Ted in the original timeline and a Ted copy in the new timeline, who might or might not be the same person.
A third option is that the new timeline is a completely new creation that just resembles the original. The people do exactly resemble each other, but this is analogous to having two unrelated people that happen to look exactly alike: while the appear to be the same, this is not due to any connection between them. This is essentially an alternative reality view in which the reality begins with a timeline branch. While this does have some appeal, if the branch is not connected to the main timeline, then one must explain how it connects to time travel. One way to do this is to take the view that what seems to be time travel just creates an alternative reality and there is, in fact, no travelling. In this case, there would be a new Ted-like person who just happens to be exactly like Ted but has no metaphysical connection to the original Ted.
This matter becomes even more complex is one starts to consider theological and moral matters. For example, if God exists and people are souls that are sent to an appropriate afterlife, then God would need to sort out who is responsible for what. This should be super easy for God, barely an inconvenience. But without God, the ethics become more challenging: if a person is split into two people, which one is accountable for the past deeds? Perhaps they both are, like an amoeba who has split into two. If a new alternative reality is created and all the people are new, they should not be accountable for any past deeds, because they have no past at that moment of creation. Time travel is, of course, an even bigger mess than one would imagine.

The grandfather problem is a classic time travel problem. Oversimplified, the problem is as follows. If time travel is possible, then a person should be able to go back in time and kill their grandfather before they have any children. But if they do, then the killer would never exist and would not be able to go back in time and kill their grandfather. So, their grandfather would not be killed and they would exist and be able to go back in time and kill him. But if they kill him, then they would not exist. And so on. There have been attempts of varying quality to solve this problem and one is to advance the notion of timeline branching. The simple version is that time is like a river and travelling back in time to change things results in the creation of a new branch of the river, flowing onward in a somewhat different direction.
Texas’ power infrastructure collapsed in the face of a winter storm, leaving many Texans in the frigid darkness. Ted Cruz infamously fled Texas in search of warmer climes, ensuring his ongoing success as an ideal Republican politician. You might expect that Texans would have responded to this disaster by addressing the underlying problems. You might, if you did not understand the Republicans of Texas.
In the context of the war on “cancel culture” Republicans professes devotion to the First Amendment, freedom of expression and the marketplace of ideas. As noted in earlier essays, they generally frame such battles in disingenuous ways or lie. For example, Republicans raged against the alleged cancellation of Dr. Seuss, but the truth is Dr. Seuss’ estate decided to stop selling six books. As another example, Republicans went into a frenzy when Hasbro renamed their Mr. Potato Head product line to “Potato Head” while keeping Mr. and Mrs. Potato Head. In these cases, the companies were not forced to do anything, and these seemed to be marketing decisions based on changing consumer tastes and values.
Another technique is the emphasis. When numbers are used, presenting them with the positive or negative statement can influence people. So, saying 52% of Americans own stocks makes it sound good. But saying 48% of Americans do not own stocks makes it sound bad. Looked at neutrally, 48% is a significant lack. After all, if 48% of Americans lacked shelter or adequate food, we would hardly rejoice that 52% had those things. So, gushing about 52% of Americans owning stock is a bit absurd.
In addition to being evil, bigotry also tends to be repetitive. For example, racists and xenophobes have relentlessly claimed that migrants are diseased job stealing criminals. This has gone on so long in the United States that descendants of migrants who were subject to these bigoted attacks are now using them against the latest wave of migrants. Another classic is the “what about the children!” tactic.
If a person dies in the United States and is not in the care of a doctor, then any investigation into their cause of death will probably be conducted by a medical examiner or coroner. To qualify as a medical examiner, a person must be a physician and are often board qualified in forensic pathology. In contrast, most states have only two qualifications for coroner: they must be of legal age and have no felony convictions. Coroners are often elected while medical examiners are usually appointed.
With a few notable exceptions, Republican politicians backed Trump’s big lie about the 2020 election. Now that Trump is back in office, the big lie has faded into the background. While most Republicans did not deny that Biden was President,
While it is tempting to think of politics as the art of lying, I content it works best when done in good faith. This is based on my conventional political philosophy. As would be expected, I accept that the legitimacy of the state rests on the consent of the governed. As thinkers like Locke and Hobbes have advanced better arguments than I can provide, so I simply steal from them. When it comes to consent, I agree with Socrates’ remarks in the Crito. For a person to consent to the rule of the state, they can neither be deceived nor coerced. People must also have the opportunity to provide this consent; in a democracy (or republic) one means of providing consent is by voting and this is why easy and secure voting is essential to the political legitimacy of a democratic state.
Since the United States has only two major parties, each includes people with very different political philosophies. For example, Harris differs greatly from Bernie Sanders. The Republican Party has become more ideologically homogenous, but it also contains some degree of diversity. Although the anti-Trump Republicans have been assimilated or purged.
