In a surprisingly contemporary passage of his Summa Theologica, Aquinas noted that the Jewish people of Old Testament times did not admit visitors from all nations equally, since those peoples closer to them were more quickly integrated into the population than those who were not as close.

The ‘Is’ of Identity and the ‘Is’ of Predication: Contra Sommers
Dedication: To Bill Clinton who taught us that much can ride on what the meaning of 'is' is.
………………
The Opponent has a very good post in which he raises the question whether the standard analytic distinction between the 'is' of identity and the 'is' of predication is but fallout from an antecedent decision to adhere to an absolute distinction between names and predicates according to which no name is a predicate and no predicate is a name. If the distinction is absolute, as Gottlob Frege and his epigoni maintain, then names cannot occur in predicate position, and a distinction between the two uses of 'is' is the consequence. But what if no such absolute distinction is made? Could one then dispense with the standard analytic distinction between the two uses of 'is'? Or are there reasons independent of Frege's function-argument analysis of propositions for upholding the distinction between the two uses?
To illustrate the putative distinction, consider
1. George Orwell is Eric Blair
and
2. George Orwell is famous.
Both sentences feature a token of 'is.' Now ask yourself: is 'is' functioning in the same way in both sentences? The standard analytic line is that 'is' functions differently in the two sentences. In (1) it expresses (numerical) identity; in (2) it expresses predication. Identity, among other features, is symmetrical; predication is not. That suffices to distinguish the two uses of 'is.' 'Famous' is predicable of Orwell, but Orwell is not predicable of 'famous.' But if Blair is Orwell, then Orwell is Blair.
Now it is clear, I think, that if one begins with the absolute name-predicate distinction, then the other distinction is also required. For if 'Eric Blair' in (1) cannot be construed as a predicate, then surely the 'is' in (1) does not express predication. The question I am raising, however, is whether the distinction between the two uses of 'is' arises ONLY IF one distinguishes absolutely and categorially between names and predicates.
Fred Sommers seems to think so. The Opponent follows him in this. Referencing the example 'The morning star is Venus,' Sommers writes, "Clearly it is only after one has adopted the syntax that prohibits the predication of proper names that one is forced to read 'a is b' dyadically and to see in it a sign of identity." (The Logic of Natural Language, Oxford 1982, p. 121, emphasis added) The contemporary reader will of course wonder how else 'a is b' could be read if it is not read as expressing a dyadic relation between a and b. How the devil could the 'is' in 'a is b' be read as a sign of predication?
The question can be put like this. Can we justify a distinction between the 'is' of identity and the 'is' of predication even if we do not make an absolute distinction between names (object words) and predicates (concept words)? I think we can.
Is it not obvious that if an individual has a property, then it is not identical to that property? Tom is hypertensive. But it would be absurd to say that Tom is identical to this property. This is so whether you think of properties as universals or as particulars (tropes). Suppose the property of being hypertensive (H-ness) is a universal and that Tom's brother Sal is also hypertensive. It follows that they share this property. So if Tom = H-ness, and Sal = H-ness, then, by the transitivity and symmetry of identity, Tom = Sal, which is absurd.
If properties are tropes, we also get an absurdity. On a trope bundle theory, Tom is a bundle of tropes. But surely Tom cannot be identical to one of his tropes, his H-trope. On a trope substratum theory, tropes are like Aristotelian accidents inhering in a substance. But surely no substance is identical to one of its accidents.
So whether properties are universals or tropes, we cannot sensibly think of an individual's having a property in terms of identity with that property. If H-ness is a universal, then we would speak of Tom's instantiating H-ness, where this relation is obviously asymmetrical and for this reason and others distinct from identity.
Now 'H' is a predicate whereas 'H-ness' is a name. But nothing stops us from parsing 'Tom is hypertensive' as 'Tom instantiates hypertensiveness.' This shows that we can uphold the distinction between the 'is' of identity and the 'is' of predication with a two-name theory of predication, and thus without making Frege's absolute distinction between names and predicates. It appears that Sommers is mistaken in his claim that "Clearly it is only after one has adopted the syntax that prohibits the predication of proper names that one is forced to read 'a is b' dyadically and to see in it a sign of identity."
I am assuming of course that we cannot eke by on predicates alone: we need properties. By my lights this should not be controversial in the least. My nominalist Opponent will demur. In 'Orwell is famous' he seems to be wanting to say that 'Orwell' and 'famous' refer to the same thing. But what could that mean?
First of all, 'Orwell' and 'famous' do not have the same extension: there are many famous people, but only one Orwell. 'Orwell is famous' is true. What makes it true? Presumably the fact that 'Orwell' and 'famous' denote one and the same individual. And which individual is that? Why, it's Orwell! But Orwell might not have been famous. Since it is contingent that Orwell is famous, but noncontingent that Orwell is Orwell, the truth-maker of 'Orwell is famous' cannot be Orwell alone. It has has to be the fact of Orwell's being famous, which fact involves the property of being famous in addition to Orwell.
Nominalists insist that we ought not multiply entities beyond necessity. They are right! But there is no multiplication beyond necessity here since we need to admit properties as features of extralinguistic reality. To explain why 'Orwell is famous' is contingent, one must distinguish Orwell from his contingently possessed properties. Man does not live or think truly by predicates alone.
Matriarchy Mitigated: Another Trumpian Accomplishment
The mitigation of creeping matriarchy requires, among other things, a 'war' against puellafication. I coined the word 'puellafication' here. An ugly word for an ugly thing. Christina Hoff Sommers combats the thing. While so doing she provides further proof that the Left is devoid of common sense:
Across the country, schools are policing and punishing the distinctive, assertive sociability of boys. Many much-loved games have vanished from school playgrounds. At some schools, tug of war has been replaced with “tug of peace.” Since the 1990s, elimination games like dodgeball, red rover and tag have been under a cloud — too damaging to self-esteem and too violent, say certain experts.
Tug of peace? Is that a joke? Peace is better than war, of course, but to secure and maintain peace one must be prepared to wage and win war. Or as the Latin saying has it, Si vis pacem, para bellum. "If you want peace, prepare for war."
Life is competitive and hierarchical. Supervised and respectful competition in the schools on the playing fields and in the classrooms is good preparation for life.
A little tuggy-wuggy never hurt anybody. Dale Tuggy would approve of this message.
And another thing. Bring back the monkey bars and the long summer vacations. Enough with the wussification. (Not a word? It is now.)
Scott Adams’ Starting Point
Here:
For new readers of this blog, my starting point is the understanding that human brains did not evolve to show us reality. We aren’t that smart. Instead, our brains create little movies in our heads, and yours can be completely different from mine. We see that situation now. Half the country thinks President Trump is well on his way to becoming a Hitler-like dictator. But many other Americans think Trump is an effective business person with good intentions. They can’t both be right.
"They can't both be right." True, but how could Adams possibly know this if the human brain does not "show us reality"? According to the "little movie" in Adams' head, Trump cannot be both Hitlerian and non-Hitlerian. But there is this other guy, Shmadams, in whose head a "completely different little movie" plays according to which Trump can be both Hitlerian and non-Hitlerian.
So I tax Adams with the following dilemma. If he is justified in his claim that "They can't both be right," then our brains sometimes "show us reality" and Adams' theory refutes itself. If, on the other hand, Adams' theory is true, then he is not justified in his assertion that "They can't both be right." Nor is he justified in believing that his theory is true.
But I hasten to add that Adams' silly speculation about the brain and reality in no way detracts from his insights into Trump's modus operandi.
He understands that Trump is a negotiator who opens the bidding with an extreme offer so as to be in a position to dial it back to something reasonable. In this way he manages to mollify, to some extent at least, the extremists on his Right and those on his Left.
Every reasonable person must grant that there must be some restrictions placed on whom to allow to immigrate. Trump will alienate Muslims and leftists but he will also insure that what has already happened in Europe won't happen here.
You lefties need to cool your jets, to use an old '70s expression, and give the man a chance. The stroke you prevent may be your own. The more extreme and thuggish your protests, the more asinine your Hitler comparisons, the more you will discredit yourselves in the eyes of the sane.
On the Value of Twitter as a Research Tool
In 2013, a college student assigned to research a deadly substance sought help via Twitter: "I can't find the chemical and physical properties of sarin gas someone please help me." An expert at a security consulting firm tried to be helpful, telling her that sarin is not gas. She replied, "yes the (expletive) it is a gas you ignorant (expletive). sarin is a liquid & can evaporate … shut the (expletive) up."
Nominalism and an Identity Theory of Predication
The Worthy Opponent comments,
We nominalists hold that 'God is good' is true when what is signified by 'God' and what is signified by 'good' are numerically one and the same thing.
I stumble over this.
Apparently, it is The Opponent's view that a sentence such 'Socrates is good' is true when what is signified by 'Socrates' and what is signified by 'good' are numerically one and the same thing. I don't understand. 'Good,' unlike 'Socrates,' is a common term: it applies to many individuals. So there cannot be numerically one thing that both 'Socrates' and 'good' signify. 'Socrates' signifies one thing; 'good' signifies many things.
If, contrary to fact, there were only one good thing, then it would make some sense to say that 'Socrates is good,' which is by its surface grammar a predication, could be read as asserting the numerical identity of Socrates with the one good thing. But if Socrates is good, or seated, or conversing with Theaetetus, this is only contingently the case. So how analyze the possibly true 'Socrates is not good' on the assumption that there is only one good thing? We would have to say that Socrates is distinct from himself — which is absurd. For if, in actuality, Socrates is good in virtue of being identical to the one good thing, then, in the possible counterfactual situation in which he — the very same individual — is not good, he would have to be numerically diverse from the one good thing, namely, himself!
The same argument goes through even if there are many good things. For the Opponent's claim is that Socrates is good in virtue of being identical to one of the many good things. Call this good thing G. The claim is that 'Socrates is good' is an identity proposition in disguise, and that its deep logical form is: S = G.
The problem is that 'Socrates is good' is contingently true. But 'S = G' is not contingently true. So the predication is not an identity proposition in disguise.
This looks to be a pretty powerful objection.
I am assuming something that is well-nigh self-evident, but which I fear the Illustrious Opponent will deny, namely, that if a = b, then this is non-contingently the case. In other words, I am assuming that if a = b, then there is no possible situation in which a and b both exist but are numerically distinct.
Curiously, the Opponent's theory works in one case and one case only. But he has to admit the divine simplicity. So assume that God exists, that God is essentially good, and that God is identical to his attributes, and that therefore God alone is good in this sense. If God is identical to his attributes, then God = the one and only good thing. (Socrates is good only in an analogical and derivative sense.) In this one case, 'God is good' is an identity proposition in disguise.
The Literary/Visual Trope of the Women’s March
I propose the synecdoche:
a figure of speech by which a part is put for the whole (as fifty sail for fifty ships), the whole for a part (as society for high society), the species for the genus (as cutthroat for assassin), the genus for the species (as a creature for a man), or the name of the material for the thing made (as boards for stage).
People who refer to women using 'vagina' or, more commonly, its obscene equivalents are employing the literary device known as the synecdoche. To refer to women as skirts, however, is not a synecdoche but a metonym. The graphic is an example of a visual synecdoche.
Time was, when feminists protested the objectification of women, and rightly so. Nowadays they self-objectify, presumably in the belief that by co-opting 'pussy' and other derogatory words they can remove their sting.
Paradoxes of Illegal Immigration
This entry from 6 January 2012 bears re-posting in the light of current events. 'Light' indeed. A new day is dawning. Things are looking up. We now have a president with the cojones to take action, and he has. Who would have thought that Donald J. Trump of all people would be the patriot to save the country? The Lord does indeed work in mysterious ways. What a week it's been! While conservatives rejoice — I mean true conservatives, not NeverTrump quislings and jokers — leftists lose their minds and descend into thuggery showing themselves plainly for what they were all along.
……………………………………
Philosophers hate a contradiction, but love a paradox. There are paradoxes everywhere, in the precincts of the most abstruse as well as in the precincts of the prosaic. Here are eight paradoxes of illegal immigration suggested to me by Victor Davis Hanson. The titles and formulations are my own. For good measure, I add a ninth, of my own invention.
The Paradox of Profiling. Racial profiling is supposed to be verboten. And yet it is employed by American border guards when they nab and deport thousands of illegal border crossers. Otherwise, how could they pick out illegals from citizens who are merely in the vicinity of the border? How can what is permissible near the border be impermissible far from it in, say, Phoenix? At what distance does permissibility transmogrify into impermissibility? If a border patrolman may profile why may not a highway patrolman? Is legal permissibility within a state indexed to spatiotemporal position and variable with variations in the latter?
The Paradox of Encroachment. The Federal government sues the state of Arizona for upholding Federal immigration law on the ground that it is an encroachment upon Federal jurisdiction. But sanctuary cities flout Federal law by not allowing the enforcement of Federal immigration statutes. Clearly, impeding the enforcement of Federal laws is far worse than duplicating and perhaps interfering with Federal law enforcement efforts. And yet the Feds go after Arizona while ignoring sanctuary cities. Paradoxical, eh?
The Paradox of Blaming the Benefactor. Millions flee Mexico for the U.S. because of the desirability of living and working here and the undesirability of living in a crime-ridden, corrupt, and impoverished country. So what does Mexican president Felipe Calderon do? Why, he criticizes the U.S. even though the U.S. provides to his citizens what he and his government cannot! And what do many Mexicans do? They wave the Mexican flag in a country whose laws they violate and from whose toleration they benefit.
The Paradox of Differential Sovereignty and Variable Border Violability. Apparently, some states are more sovereign than others. The U.S., for some reason, is less sovereign than Mexico, which is highly intolerant of invaders from Central America. Paradoxically, the violability of a border is a function of the countries between which the border falls.
The Paradox of Los Locos Gringos. The gringos are crazy, and racist xenophobes to boot, inasmuch as 70% of them demand border security and support AZ SB 1070. Why then do so many Mexicans want to live among the crazy gringos?
The Paradox of Supporting While Stiffing the Working Stiff. Liberals have traditionally been for the working man. But by being soft on illegal immigration they help drive down the hourly wages of the working poor north of the Rio Grande. (As I have said in other posts, there are liberal arguments against illegal immigration, and here are the makings of one.)
The Paradox of Penalizing the Legal while Tolerating the Illegal. Legal immigrants face hurdles and long waits while illegals are tolerated. But liberals are supposed to be big on fairness. How fair is this?
The Paradox of Subsidizing a Country Whose Citizens Violate our Laws. "America extends housing, food and education subsidies to illegal aliens in need. But Mexico receives more than $20 billion in American remittances a year — its second-highest source of foreign exchange, and almost all of it from its own nationals living in the United States." So the U.S. takes care of illegal aliens from a failed state while subsidizing that state, making it more dependent, and less likely to clean up its act.
The Paradox of the Reconquista. Some Hispanics claim that the Southwest and California were 'stolen' from Mexico by the gringos. Well, suppose that this vast chunk of real estate had not been 'stolen' and now belonged to Mexico. Then it would be as screwed up as the rest of Mexico: as economically indigent, as politically corrupt, as crime-ridden, as drug-infested. Illegal immigrants from southern Mexico would then, in that counterfactual scenario, have farther to travel to get to the U.S., and there would be less of the U.S. for their use and enjoyment. The U.S. would be able to take in fewer of them. They would be worse off. So if Mexico were to re-conquer the lands 'stolen' from it, then it would make itself worse off than it is now. Gaining territory it would lose ground — if I may put paradoxically the Paradox of the Reconquista.

Undocumented Workers and Illegal Aliens
One of the purposes of this website is to combat the stupidity of Political Correctness, a stupidity that in many contemporary liberals, i.e., leftists, is willful and therefore morally censurable. The euphemism 'undocumented worker' is a good example of a PC expression. It does not require great logical acumen to see that 'undocumented worker' and 'illegal alien' are not coextensive expressions. The extension of a term is the class of things to which the term applies. In the diagram below, let A be the class of illegal aliens, B the class of undocumented workers, and A^B the intersection of these two classes. All three regions in the diagram are non-empty, which shows that A and B are not coextensive, and so are not the same class. Since A and B are not the same class, 'undocumented worker' and 'illegal alien' do not have the same intension or meaning. If two terms differ in extension, then they differ in meaning. (The converse does not hold.) Differing in both extension and intension (sense, meaning), 'undocumented workers' and 'illegal aliens' expressions are not intersubstitutable.
To see why, note first that there are illegal aliens who are not workers since they are either petty criminals, or members of organized criminal gangs e.g., MS-13, some of whose illegal alien members are terrorists, or too young to work, or unable to work. Note second that there are illegal aliens who have documents all right — forged documents. Note third that there are undocumented workers who are not aliens: there are American citizens who work but without the legally requisite licenses and permits.
So the correct term is 'illegal alien.' It is descriptive and accurate and there is no reason why it should not be used.
Now will this little logical exercise convince a leftist to use language responsibly and stop obfuscating the issue? Of course not. Leftism in some of its forms is willfully embraced reality denial, and in other of its forms is a cognitive aberration, something like a mental illness, in need of therapy rather than refutation. The latter are sick and one cannot refute the sick. They need treatment and quarantine and those who go near them should employ appropriate prophylactics.
So why did I bother writing the above? Because there are people who have not yet succumbed to the PC malady and might benefit from a bit of logical prophylaxis. One can hope.
Hope for the best. But prepare for the worst.
The winds of change that have blown the Orange Man into the White House have brought us to the shores of hope, hope for a return to sanity and order and the rule of law.

How Could a Simple God be a Person?
The Worthy Opponent writes,
And how is the view of divine simplicity and consequent unintelligibility consistent with the view of God as a person? A person has a mind whose thoughts and feelings are distinct and successive. As Hume (1711–76) argued, a being who is simple has ‘no thought, no reason, no will, no sentiment, no love, no hatred; or in a word, is no mind at all’.i Yet God is obviously a person, according to Plantinga and othersii. Then he is obviously not simple.
i Hume, David. Dialogues concerning Natural Religion. Edited by Richard Popkin. Indianapolis, IN: Hackett, 1980, part 4.
ii Does God Have a Nature? Milwaukee, WI: Marquette University Press, 1980. See Eleanor Stump on the same. ‘We can say ‘you’ to God’. God is a particular, with a mind and a will. ‘We can say ‘you’ to one another, and say ‘you’ to God’.
This is a very hard nut to crack. The problem cannot be solved, in my opinion, by simply denying the divine simplicity. For there is a very powerful argument for it. As I say elsewhere:
I believe a case can be made, pace Alvin Plantinga and other theistic deniers of divine simplicity, that to deny the absolute ontological simplicity of God is to deny theism itself. For what we mean by 'God' is an absolute reality, something metaphysically ultimate, "that than which no greater can be conceived." (Anselm) Now an absolute reality cannot depend for its existence or nature or value upon anything distinct from itself. It must be from itself alone, or a se. Nothing could count as divine, or worthy of worship, or be an object of our ultimate concern, or be maximally great, if it lacked the property of aseity. But the divine aseity, once it is granted, seems straightaway to entail the divine simplicity, as Aquinas argues in ST. For if God is not dependent on anything else for his existence, nature, and value, then God is not a whole of parts, for a whole of parts depends on its parts to be and to be what it is. So if God is a se, then he is not a composite being, but a simple being. This implies that in God there is no real distinction between: existence and essence, form and matter, act and potency, individual and attribute, attribute and attribute. In sum, if God is God, then God is simple. To deny the simplicity of God is to deny the existence of God. It is therefore possible for an atheist to argue: Nothing can be ontologically simple, therefore, God cannot exist.
A theist who denies divine simplicity might conceivably be taxed with idolatry inasmuch as he sets up something as God that falls short of the exacting requirements of deity. The divine transcendence would seem to require that God cannot be a being among beings, but must in some sense be Being itself . (Deus est ipsum esse subsistens: God is not an existent but self-subsisting Existence itself.) On the other hand, a theist who affirms divine simplicity can be taxed, and has been taxed, with incoherence. As an aporetician first and foremost, I seek to lay bare the problem in all its complexity under suspension of the natural urge for a quick solution.
In sum, God must be simple to be God. On the other hand, there can no denying of the force of the Opponent's objection. It has two prongs: the notion of a simple being is unintelligible; no person is simple. But God is a person. This cannot be denied either. We appear to be nailed to the cross of the following aporetic triad:
A.God is a person.
B. No person is simple.
C. God is simple.
The classical theist accepts all three propositions. But they are inconsistent. Some theists will argue that the inconsistency is merely apparent. I don't believe that this can be compellingly established, and neither does the Opponent. He thinks the inconsistency real and so concludes that God is not simple. This makes sense, of course, but it is not quite satisfactory, ignoring as it does the powerful arguments for divine simplicity. God can be neither an impersonal absolute nor a personal non-absolute. The Opponent ends up with the view that God is a personal non-absolute.
I myself am inclined to adopt a mysterian 'solution' according to which we accept all three propositions while confessing that we cannot understand how they could all be true.
If we have good reason to believe that p is true, and good reason to believe that q is true, then we have good reason to believe that p and q are logically consistent (with each other) despite an absence of understanding as to how they could be mutually consistent. What is actual is possible whether or not one can render intelligible how it is possible. For example, motion is actual, hence possible, despite my inability in the teeth of Zenonian considerations to understand how it is possible. Many similar examples could be given.
And so a mysterian move suggests itself: We are justified in maintaining both that God is simple and that God is a person despite the fact that after protracted effort we cannot make logical sense of this conjunction. The fact that the conjunction — God is simple & God is a person — appears to us, and perhaps even necessarily appears to us, given irremediable cognitive limitations on our part, to be or rather entail an explicit logical contradiction is not a good reason to reject the conjunction. The mysterian is not a dialetheist: he does not claim that there are true contradictions. Like the rest of us, the mysterian eschews them like the plague. His point is rather that a proposition's non-episodic and chronic seeming to be a contradiction does not suffice for its rejection. For it may well be that certain truths are inaccessible to us due to our mental limitations and defects, and that among these truths are some that appear to us only in the guise of contradictions, and must so appear.
Compare the mind-body problem. Many are inclined to say that that in us which thinks is the brain. But the brain is wholly material, and matter can't think. No physical state as physical states are understood by physics has semantic content and is directed to an object. Colin McGinn suggests that our cognitive architecture is such as to prevent us from understanding how the limbs of this apparent contradiction can all be true. How the brain thinks is thus a mystery. I am not endorsing McGinn's materialist mysterianism but suggesting that a mysterian approach to theological topics may be the best we can do. Besides divine simplicity, Trinity, Incarnation, and Real Presence are all arguably impervious to understanding by the discursive intellect. We just cannot see how they could be logically possible.
America First
Contrary to what Kristol seems to think, America First is a notion sound and defensible and in no way depressing although it is vulgar in the root sense of the word as I will explain at the end of this entry. Herewith, some notes on what America First means, or rather, what I think it ought to mean. I fancy that I am not far from the meaning Trump would articulate if he were an articulate man.
It does not mean that that the USA ought to be first over other countries, dominating them. It means that every country has the right to prefer itself and its own interests over the interests of other countries. We say 'America first' because we are Americans; the Czechs say or ought to say 'Czech Republic first.' The general principle is that every country has a right to grant preference to itself and its interests over the interests of other countries while respecting their interests and right to self-determination. America First is but an instance of the general principle. The principle, then, is Country First. If I revert to America First, that is to be understand as an instance of Country First.
So America First has nothing to do with chauvinism which could be characterized as a blind and intemperate patriotism, a belligerent and unjustified belief in the superiority of one's own country. America First expresses an enlightened nationalism which is obviously compatible with a sober recognition of national failings. Germany has a rather sordid history; but Germany First is compatible with a recognition of the wrong turn that great nation took during a well-known twelve-year period (1933-1945) in her history.
An enlightened nationalism is distinct from nativism inasmuch as the former does not rule out immigration. By definition, an immigrant is not a native; but an enlightened American nationalism accepts immigrants who accept American values, which of course are not the values of the Left.
An enlightened nationalism is not isolationist. What it eschews is a fruitless meddling and over-eager interventionism. It does not rule out certain necessary interventions when they are in our interests and in the interests of our allies.
So America First is not to be confused with chauvinism or nativism or isolationism.
America First is as sound an idea as that each family has the right to prefer its interests over the interests of other families. If my wife becomes ill, then my obligation is to care for her and expend such financial resources as are necessary to see to her welfare. If this means reducing my charitable contributions to the local food bank, then so be it. Whatever obligations I have to help others 'ripple out' from myself as center, losing claim to my attention the farther out they go, much like the amplitude of waves caused by a rock's falling into a pond diminishes the farther from the point of impact. Spouse and/or children first, then other family members, then old friends, then new friends, then neighbors, and so on.
The details are disputable, but not the general principle. The general principle is that we are justified in looking to our own first.
The main obligation of a government is to protect and serve the citizens of the country of which it is the government. It is a further question whether it has obligations to protect and benefit the citizens of other countries. That is debatable. But if it does, those obligations are trumped by the main obligation just mentioned. I should think that a great nation such as the USA does well to engage in purely humanitarian efforts such as famine relief. Such efforts are arguably supererogatory.
One implication of Country First is that an immigration policy must be to the benefit of the host country. The interests of the members of the host country trump the interests of the immigrants. Obviously, there is no blanket right to immigrate. Obviously, potential immigrants must be vetted and must meet certain standards. Obviously, no country is under any obligation to accept subversive elements or elements who would work to undermine the nation's culture.
Suppose you disagree with the enlightened nationalism I am sketching. What will you put in its place? If you are not a nationalist, what are you? Some sort of internationalist or cosmopolitan. But the notion of being a citizen of the world is empty since there is no world government and never will be. What could hold it together except the hegemony of one of the nations or a coalition of nations ganging up on the others?
The neocons tried to press America and it values and ways upon the world or upon the Middle Eastern portion thereof. The neocon mistake was to imagine that our superior system of government could be imposed on benighted and backward peoples riven by tribal hatreds and depressed by an inferior religion. The folly of that should now be evident. One cannot bomb the benighted into Enlightenment.
Leftist internationalists want to bring the world to America thereby diluting and ultimately destroying our values. The mistake of the multi-culti cultural Marxists is to imagine that comity is possible without commonality, that wildly diverse sorts of people can live together in peace and harmony. Or at least that is one mistake of the politically correct multi-cultis.
So the way forward is enlightened nationalism. Trump understands this in his intuitive and inarticulate way.
As for Bill Kristol, his use of 'vulgar' betrays him. His brand of yap-and-scribble, inside-the-Beltway, bow-tied, pseudo-conservatism puts a premium on courtly behavior and gentlemanly debate that is an end in itself and rarely issues in ameliorative action. The people, however, demand action. Kristol is not a man of the people. Trump the billionaire is, paradoxical as that sounds. He is 'vulgar' in a way that Kristol can never be.
