Are immigration restrictions compatible with liberalism? Recently, Freiman and Hidalgo have argued that immigration restrictions conflict with the core commitments of liberalism. A society with immigration restrictions in place may well be optimal in some desired respects, but it is not liberal, they argue. So if you care about liberalism more deeply than you care about immigration restrictions, you should give up on restrictionism. You can’t hold on to both. I argue here that many restrictions on contractual, economic, and associational (...) liberties seem to be justified by considerations other than liberty – thus the task for Freiman and Hidalgo is to tell us why such restrictions are justified but immigration restrictions are not. Moreover, even if this worry can be addressed, I argue, liberalism is not committed to its own demise in scenarios where there exist large enough numbers of would-be immigrants who accept and endorse illiberal norms in a way that is sufficiently resistant to change. Such a commitment requires thinking of border coercion as violating an absolute deontological constraint. This, I contend, is implausible. (shrink)

Political protests, debates on college campuses, and social media tirades make it seem like everyone is speaking their minds today. Surveys, however, reveal that many people increasingly feel like they're walking on eggshells when communicating in public. Speaking your mind can risk relationships and professional opportunities. It can alienate friends and anger colleagues. Isn't it smarter to just put your head down and keep quiet about controversial topics? In this book, Hrishikesh Joshi offers a novel defense of speaking (...) your mind. He explains that because we are social creatures, we never truly think alone. What we know depends on what our community knows. And by bringing our unique perspectives to bear upon public discourse, we enhance our collective ability to reach the truth on a variety of important matters. Speaking your mind is also important for your own sake. It is essential for developing your own thinking. And it's a core aspect of being intellectually courageous and independent. Joshi argues that such independence is a crucial part of a well-lived life. The book draws from Aristotle, John Stuart Mill, Friedrich Nietzsche, Bertrand Russell, and a range of contemporary thinkers to argue that it's OK to speak your mind. Key Features Shows that we have not just a right but a moral duty to publicly share what we know. Argues that discussing your unique ideas with others is essential for developing as a critical thinker. Explores the value of intellectual honesty and independence in the writings of John Stuart Mill and Friedrich Nietzsche and connects their thinking to contemporary problems. Argues that avoiding cultural blind spots today is important for the fate of future generations. (shrink)

Epistemic paternalism involves interfering with the inquiry of others, without their consent, for their own epistemic good. Recently, such paternalism has been discussed as a method of getting the broader public to have more accurate views on important policy relevant matters. In this paper, I discuss a novel problem for such paternalism—what I call epistemic spillovers. The problem arises because what matters for rational belief is one’s total evidence, and further, individual pieces of evidence can have complex interactions with one (...) another. Because of this, I argue that justified epistemic paternalism requires the would-be paternalist to be in an unusually strong epistemic position, one that most would-be paternalists are unlikely to meet.

The American political landscape exhibits significant polarization. People’s political beliefs cluster around two main camps. However, many of the issues with respect to which these two camps disagree seem to be rationally orthogonal. This feature raises an epistemic challenge for the political partisan. If she is justified in consistently adopting the party line, it must be true that her side is reliable on the issues that are the subject of disagreements. It would then follow that the other side is anti-reliable (...) with respect to a host of orthogonal political issues. Yet, it is difficult to find a psychologically plausible explanation for why one side would get things reliably wrong with respect to a wide range of orthogonal issues. While this project’s empirical discussion focuses on the US context, the argument generalizes to any situation where political polarization exists on a sufficiently large number of orthogonal claims.

This paper argues for the existence of a certain type of defeater for one’s belief that P—the presence of social incentives not to share evidence against P. Such pressure makes it relatively likely that there is unpossessed evidence that would provide defeaters for P because it makes it likely that the evidence we have is a lopsided subset. This offers, I suggest, a rational reconstruction of a core strand of argument in Mill’s On Liberty. A consequence of the argument is (...) that on morally and politically laden issues in particular, a high degree of doxastic openness might be appropriate. (shrink)

According to many philosophers, the world should embrace open borders – that is, let people move around the globe and settle as they wish, with exceptions made only in very specific cases such as fugitives or terrorists. Defenders of open borders have adopted two major argumentative strategies. The first is to claim that immigration restrictions involve coercion, and then show that such coercion cannot be morally justified. The second is to argue that adopting worldwide open borders policies would make the (...) world a much better place, particularly by improving average well-being. This essay contends that both of these argumentative strategies fail. Some immigration restrictions are not only morally justified, but morally required. (shrink)

In philosophical work on the ethics of conversational exchange, much has been written regarding the speaker side—i.e., on the rights and duties we have as speakers. This paper explores the relatively neglected topic of the duties pertaining to listeners’ side of the exchange. Following W.K. Clifford, we argue that it’s fruitful to think of our epistemic resources as common property. Furthermore, listeners have a key role in maintaining and improving these resources, perhaps a more important role than speakers. We develop (...) this idea by drawing from Hugo Mercier and Dan Sperber’s “interactionist” picture of reason, which suggests that reasoning is essentially dialogical and relies on the epistemic vigilance of listeners. The paper defends an imperfect, prima facie duty to listen, one that is sufficiently strong to place substantial demands on individuals, but not so overly demanding as to be implausible. (shrink)

This paper explores some key commitments of the idea that it can be rational to do what you believe you ought not to do. I suggest that there is a prima facie tension between this idea and certain plausible coherence constraints on rational agency. I propose a way to resolve this tension. While akratic agents are always irrational, they are not always practically irrational, as many authors assume. Rather, “inverse” akratics like Huck Finn fail in a distinctively theoretical way. What (...) explains why akratic agents are always either theoretically or practically irrational? I suggest that this is true because an agent’s total evidence determines both the beliefs and the intentions it is rational for her to have. Moreover, an agent’s evidence does so in a way such that it is never rational for the agent to at once believe that she ought to Φ and lack the intention to Φ. (shrink)

Censorship involves, inter alia, adopting a certain type of epistemic policy. While much has been written on the harms and benefits of free expression, and the associated rights thereof, the epistemic preconditions of justified censorship are relatively underexplored. In this paper, I argue that examining intrapersonal norms of how we ought to treat evidence that might come to us over time can shed light on interpersonal norms of evidence generation and sharing that are relevant in the context of censorship. The (...) upshot is that justified censorship requires the censor to meet a very high epistemic burden regarding the target proposition(s)—importantly, one that exceeds knowledge. (shrink)

Following Anthony Downs’s classic economic analysis of democracy, it has been widely noted that most voters lack the incentive to be well-informed. Recent empirical work, however, suggests further that political partisans can display selectively lazy or biased reasoning. Unfortunately, political knowledge seems to exacerbate, rather than mitigate, these tendencies. In this paper, I build on these observations to construct a more general skeptical challenge which affects what I call creedal beliefs. Such beliefs share three features: (i) the costs to the (...) individual of being wrong are negligible, (ii) the beliefs are subject to social scrutiny, and (iii) the evidential landscape relevant to the beliefs is sufficiently complex so as to make easy verification difficult. Some philosophers and social scientists have recently argued that under such conditions, beliefs are likely to play a signaling, as opposed to a navigational role, and that our ability to hold beliefs in this way is adaptive. However, if this is right, I argue there is at least a partial debunker for such beliefs. Moreover, this offers, I suggest, one way to develop the skeptical challenge based on etiological explanation that John Stuart Mill presents in On Liberty when he claims that the same causes which lead someone to be a devout Christian in London would have made them a Confucian in Peking. Finally, I contend that this skeptical challenge is appropriately circumscribed so that it does not over-extend in an implausible way. (shrink)

A pervasive feature of democracy is disagreement. And in general, when we encounter disagreement from someone who is at least more reliable than chance, this puts some pressure on us to moderate our beliefs. But this raises the specter of asymmetric compliance—it’s not obvious what to do when we moderate our beliefs but the other party refuses to do so. Whereas an elegant solution is available when it comes to how we can to respond to our higher-order evidence while still (...) preserving democratic fairness, I argue that no such solution is forthcoming when we consider zetetic intransigence—that is, asymmetric compliance with regards to how we inquire, or gather evidence. The upshot is that democratic participation can involve messy tradeoffs with no entirely satisfactory resolution. (shrink)

Within the immigration debate, libertarians have typically come down in favor of open borders by defending two main ideas: i) individuals have a right to free movement; and ii) immigration restrictions are economically inefficient, so that lifting them can make everyone better off. This entry describes the rationale for open borders from a libertarian perspective (in part by analogy to the debate around minimum wage laws). Three main objections within the immigration literature are then discussed: i) the view that states (...) may restrict immigration to protect the interests (e.g. jobs) of their domestic needy; ii) the claim that restrictions are justified as a means of preserving culture; and iii) the influential argument that the right to freedom of association entails a right to exclude. These arguments are well-known, and I describe some of the compelling responses to be found in the recent literature. The essay then turns to more neglected critiques. The first concerns how liberal regimes should think about immigration from countries where the dominant norms are illiberal. The second examines the idea that political and economic institutions are sensitive to immigration policy, especially in the long run. Both of these critiques approach the topic from a non-ideal theory perspective, emphasizing the “public choice” dimensions of immigration policy. The entry closes by suggesting that this form of critique is especially important for open-borders libertarians to respond to given their general commitments to non-ideal, non-romantic theorizing in the context of government institutions and policy.

According to G.A. Cohen, the principles of justice are insensitive to facts about human moral limitations. This assumption allows him to mount a powerful defense of socialism. Here, I present a dilemma for Cohen. On the one hand, if such socialism is to be realized through collective property ownership, then the information problem renders the ideal incoherent, not merely infeasible. On the other hand, if socialism is to incorporate private ownership of productive assets, then Cohen loses the resources to distinguish (...) his view from capitalism. For, if agents were ideally motivated, there would be no need for coercive taxation schemes and limitations on trade. Moreover, incorporating coercion drastically undermines Cohen’s original argument for socialism, which relies on an analogy to a camping trip among friends. (shrink)

This chapter argues that governments have a duty to take reasonably effective and humane steps to minimize the occurrence of unauthorized migration and stay. While the effects of unauthorized migration on a country’s citizens and institutions have been vigorously debated, the literature has largely ignored duties of fairness to would-be immigrants. It is argued here that failing to take reasonable steps to prevent unauthorized migration and stay is deeply unfair to would-be immigrants who are not in a position to bypass (...) visa regulations. Importantly, the argument here is orthogonal to the debate as to how much and what kinds of immigration ought to be allowed. (shrink)

Consider a binary afterlife, wherein some people go to Heaven, others to Hell, and nobody goes to both. Would such a system be just? Theodore Sider argues: no. For, any possible criterion of determining where people go will involve treating very similar individuals very differently. Here, I argue that this point has deep and underappreciated implications for moral philosophy. The argument proceeds by analogy: many ethical theories make a sharp and practically significant distinction between persons and non-persons. Yet, just like (...) in the binary afterlife, this involves treating very similar individuals very differently. I propose two ways out. The first is to deny that such theories are strictly speaking true, but to claim that it is practically best if people adopt them. The second is to modify such theories so as to allow for continuous variation in the scope and strength of the moral obligations arising from personhood. (shrink)

Where does normativity come from? Or alternatively, in virtue of what do facts about what an agent has reason to do obtain? On one class of views, reason facts obtain in virtue of agents’ motivations. It might seem like a truism that at least some of our reasons depend on what we desire or care about. However, some philosophers, notably Derek Parfit, have convincingly argued that no reasons are grounded in this way. Typically, this latter, externalist view of reasons has (...) been thought to enjoy the advantage of extensional adequacy—that is, the ability to account for all the reasons we intuitively think people have. This paper provides a novel argument against this assumption by considering a type of case wherein the relative strengths of the agent’s reasons can only be adequately explained by reference to what she cares about. Adding some further assumptions yields that there are at least some internally sourced reasons. (shrink)

Can a liberal state exclude illiberal immigrants in order to preserve its liberal status? Hrishikesh Joshi has argued that liberalism cannot require a commitment to open borders because this would entail that liberalism is committed to its own demise in circumstances in which many illiberal immigrants aim to immigrate into a liberal society. I argue that liberalism is committed to its own demise in certain circumstances, but that this is not as bad as it may appear. Liberalism’s commitment (...) to its own demise is merely a reflection of the fact that it must take into account the rights of outsiders, not just the rights of existing citizens, and of the fact that circumstances of injustice can sometimes leave liberal societies with no correct choice.

In Why It's OK to Speak Your Mind, Hrishikesh Joshi argues that the open exchange of ideas is essential for the flourishing of individuals and society. He provides two arguments for this claim. First, speaking your mind is essential for the common good: we enhance our collective ability to reach the truth if we share evidence and offer different perspectives. Second, speaking your mind is good for your own sake: it is necessary to develop your rational faculties and (...) exercise intellectual independence, both of which are essential for living a good life. In this paper, I consider the implications of Joshi’s argument and raise several objections to his view. (shrink)

Two enzymes involved in the synthesis of pyrimidine and purine nucleotides, CTP synthase (CTPS) and IMP dehydrogenase (IMPDH), can assemble into a single or very few large filaments called rods and rings (RR) or cytoophidia. Most recently, asymmetric cytoplasmic distribution of organelles during cell division has been described as a decisive event in hematopoietic stem cell fate. We propose that cytoophidia, which could be considered as membrane‐less organelles, may also be distributed asymmetrically during mammalian cell division as previously described for (...) Schizosaccharomyces pombe. Furthermore, because each type of nucleotide intervenes in distinct processes (e.g., membrane synthesis, glycosylation, and G protein‐signaling), alterations in the rate of synthesis of specific nucleotide types could influence cell differentiation in multiple ways. Therefore, we hypothesize that whether a daughter cell inherits or not CTPS or IMPDH filaments determines its fate and that this asymmetric inheritance, together with the dynamic nature of these structures enables plasticity in a cell population.

Increased amyloid beta (Aβ) production by sequential cleavage of the amyloid precursor protein (APP) by the β‐ and γ‐secretases contributes to the etiological basis of Alzheimer's disease (AD). This process requires APP and the secretases to be in the same subcellular compartments, such as the endosomes. Since all membrane organelles in the endomembrane system are kinetically and functionally linked, any defects in the trafficking and sorting machinery would be expected to change the functional properties of the whole system. The Golgi (...) is a primary organelle for protein trafficking, sorting and modifications, and Golgi defects have been reported in AD. Here we hypothesize that Golgi fragmentation in AD accelerates APP trafficking and Aβ production. Furthermore, Golgi defects may perturb the proper trafficking and processing of many essential neuronal proteins, resulting in compromised neuronal function. Therefore, molecular tools that can restore Golgi structure and function could prove useful as potential drugs for AD treatment. (shrink)

We address Northcott’s criticism of Pearson’s correlation coefficient ‘r’ in measuring causal strength by replacing Pearson’s linear regressions by nonparametric nonlinear kernel regressions. Although new proof shows that Suppes’ intuitive causality condition is neither necessary nor sufficient, we resurrect Suppes’ probabilistic causality theory by using nonlinear tools. We use asymmetric generalized partial correlation coefficients from Vinod [2014] as our third criterion in addition to two more criteria. We aggregate the three criteria into one unanimity index, UI in [-100; 100], quantifying (...) causal strengths associated with causal paths: Xi -> Xj, Xj -> Xi, and Xi Xj. (shrink)

Sensorimotor learning refers to improvements that occur through practice in the performance of sensory-guided motor behaviors. Leveraging novel technical capabilities of an immersive virtual environment, we probed the component kinematic processes that mediate sensorimotor learning. Twenty naïve subjects performed a simulated marksmanship task modeled after Olympic Trap Shooting standards. We measured movement kinematics and shooting performance as participants practiced 350 trials while receiving trial-by-trial feedback about shooting success. Spatiotemporal analysis of motion tracking elucidated the ballistic and refinement phases of hand (...) movements. We found systematic changes in movement kinematics that accompanied improvements in shot accuracy during training, though reaction and response times did not change over blocks. In particular, we observed longer, slower, and more precise ballistic movements that replaced effort spent on corrections and refinement. Collectively, these results leverage developments in immersive virtual reality technology to quantify and compare the kinematics of movement during early learning of full-body sensorimotor orienting.

We describe a categorial system (PPTS) based on partial proof trees(PPTs) as the building blocks of the system. The PPTs are obtained byunfolding the arguments of the type that would be associated with a lexicalitem in a simple categorial grammar. The PPTs are the basic types in thesystem and a derivation proceeds by combining PPTs together. We describe theconstruction of the finite set of basic PPTs and the operations forcombining them. PPTS can be viewed as a categorial system incorporating someof (...) the key insights of lexicalized tree adjoining grammar, namely the notionof an extended domain of locality and the consequent factoring of recursionfrom the domain of dependencies. PPTS therefore inherits the linguistic andcomputational properties of that system, and so can be viewed as a middleground between a categorial grammar and a phrase structure grammar. We alsodiscuss the relationship between PPTS, natural deduction, and linear logicproof-nets, and argue that natural deduction rather than a proof-net systemis more appropriate for the construction of the PPTs. We also discuss howthe use of PPTs allows us to localize the management of resources, therebyfreeing us from this management as the PPTs are combined. (shrink)

The role of antibody-antigen affinity and concentrations in adaptive antibody response is analyzed in a framework of probabilistic inventory model for antibody production. Our results indicate significant differences in optimal behaviours of low, moderate and high affinity groups and offer important implications. Interestingly, the involved approach is also of relevance in other production systems. Directions for its applications in industries and information sciences are also presented.
