With narrow search; and with inspection deep
Considered every creature, which of all
Most opportune might serve his wiles; and found
The Serpent subtlest beast of all the field.

“Imagine,” wrote the literary critic Terry Eagleton some years ago in the first line of his review of the biologist Richard Dawkins’ book, The God Delusion, “someone holding forth on biology whose only knowledge of the subject is the Book of British Birds, and you have a rough idea of what it feels like to read Richard Dawkins on theology.” Eagleton could quite easily have left things there—the rest of the review contains not much more information, though if you have a taste for that kind of thing it does have quite a few more mildly-entertaining slurs. Like a capable prosecutor, Eagleton arraigns Dawkins for exceeding his brief as a biologist: that is, of committing the scholarly heresy of speaking from ignorance. Worse, Eagleton appears to be right: of the two, clearly Eagleton is better read in theology. Yet although it may be that Dawkins the real person is ignorant of the subtleties of the study of God, the rules of logic suggest that it’s entirely possible that someone could be just as educated as Eagleton in the theology—and yet hold arguably views closer to Dawkins’ than to Eagleton’s. As it happens, that person not only once existed, but Eagleton wrote a review of someone else’s biography of him. His name is Thomas Aquinas.
Thomas Aquinas is, of course, the Roman Catholic saint whose writings stand, even today, as the basis of Church doctrine: according to Aeterni Patris, an encyclical delivered by Pope Leo XIII in 1879, Aquinas stands as “the chief and master of all” the scholastic Doctors of the church. Just as, in other words, the scholar Richard Hofstadter called American Senator John Calhoun of South Carolina “the Marx of the master class,” so too could Aquinas be called the Marx of the Catholic Church: when a good Roman Catholic searches for the answer to a difficult question, Aquinas is usually the first place to look. It might be difficult then to think of Aquinas, the “Angelic Doctor” as he is sometimes referred to by Catholics, as being on Dawkins’ side in this dispute: both Aquinas and Eagleton lived by means of examining old books and telling people about what they found, whereas Dawkins is, by training at any rate, a zoologist.
Yet, while in that sense it could be argued that the Good Doctor (as another of his Catholic nicknames puts it) is therefore more like Eagleton (who was educated in Catholic schools) than he is like Dawkins, I think it could equally well be argued that it is Dawkins who makes better use of the tools Aquinas made available. Not merely that, however: it’s something that can be demonstrated simply by reference to Eagleton’s own work on Aquinas.
“Whatever other errors believers may commit,” Eagleton for example says about Aquinas’ theology, “not being able to count is not one of them”: in other words, as Eagleton properly says, one of the aims of Aquinas’ work was to assert that “God and the universe do not make two.” That’s a reference to Aquinas’ famous remark, sometimes called the “principle of parsimony,” in his magisterial Summa Contra Gentiles: “If a thing can be done adequately by means of one, it is superfluous to do it by means of several; for we observe that nature does not employ two instruments where one suffices.” But what’s strange about Eagleton’s citation of Aquinas’ thought is that it is usually thought of as a standard argument on Richard Dawkins’ side of the ledger.
Aquinas’ statement is after all sometimes held to be one of the foundations of scientific belief. Sometimes called “Occam’s Razor,” Isaac Newton referred to Aquinas’ axiom in the Principia Mathematica when the great Englishman held that his work would “admit no more causes of natural things than such as are both true and sufficient to explain their appearances.” Later still, in a lecture Albert Einstein gave at Oxford University in 1933, Newton’s successor affirmed that “the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.” Through these lines of argument runs more or less Aquinas’ thought that there is merely a single world—it’s just that the scientists had a rather different idea of what that world is than Aquinas did.
“God for Aquinas is not a thing in or outside the world,” according to Eagleton, “but the ground of possibility of anything whatever”: that is, the world according to Aquinas is a God-infused one. The two great scientists seem to have held, however, a position closer to the view supposed to have been expressed to Napoleon by the eighteenth-century mathematician Pierre-Simon LaPlace: that there is “no need of that hypothesis.” Both in other words think there is a single world; the distinction to be made is simply whether the question of God is important to that world’s description—or not.
One way to understand the point is to say that the scientists have preserved Aquinas’ way of thinking—the axiom sometimes known as the “principle of parsimony”—while discarding (as per the principle itself) that which was unnecessary: that is, God. Viewed in that way, the scientists might be said to be more like Aquinas than Aquinas—or, at least, than Terry Eagleton is like Aquinas. For Eagleton’s disagreement with Aquinas is different: instead of accepting the single-world hypothesis and rejecting whether it is God or not, Eagleton’s contention is with the “principle of parsimony” itself—the contention that there can be merely a single explanation for the world.
Now, getting into that whole subject is worth a library, so we’ll leave it aside here; let me simply ask you to stipulate that there is a lot of discussion about Occam’s Razor and its relation to the sciences, and that Terry Eagleton (a—former?—Marxist) is both aware of it and bases his objection to Aquinas upon it. The real question to my mind is this one: although Eagleton—as befitting a political radical—does what he does on political grounds, is the argumentative move he makes here as legitimate and as righteous as he makes it out to be? The reason I ask this is because the “principle of parsimony” is an essential part of a political case that’s been made for over two centuries—which is to say that, by abandoning Thomas Aquinas’ principle, people adopting Eagleton’s anti-scientific view are essentially conceding that political goal.
That political application concerns the design of legislatures: just as Eagleton and Dawkins argue over whether there is a single world or two, in politics the question of whether legislatures ought to have one house or two has occupied people for centuries. (Leaving aside such cases as Sweden, which once had—in a lovely display of the “diversity” so praised by many of Eagleton’s compatriots—four legislative houses.) The French revolutionary leader, the Abbè Sieyés—author of the manifesto of the French Revolution, What Is the Third Estate?—has likely put the case for a single house most elegantly: the abbè once wrote that legislatures ought to have one house instead of two on the grounds that “if the second chamber agrees with the first, it is useless; if it disagrees it is dangerous.” Many other French revolutionary leaders had similar thoughts: for example, Mirabeau wrote that what are usually termed “second chambers,” like the British House of Lords or the American Senate, are often “the constitutional refuge of the aristocracy and the preservation of the feudal system.” The Marquis de Condorcet thought much the same. But such a thought has not been limited to the eighteenth-century, nor to the right-hand side of the English Channel.
Indeed, there has long been similar-minded people across the Channel—there’s reason in fact to think that the French got the idea from the English in the first place given that Oliver Cromwell’s “Roundhead” regime had abolished the House of Lords in 1649. (Though it was brought back after the return of Charles II.) In 1867’s The English Constitution, the writer and editor-in-chief of The Economist, Walter Bagehot, had asserted that the “evil of two co-equal Houses of distinct natures is obvious.” George Orwell, the English novelist and essayist, thought much the same: in the early part of World War II he fully expected that the need for efficiency produced by the war would result in a government that would “abolish the House of Lords”—and in reality, when the war ended and Clement Atlee’s Labour government took power, one of Orwell’s complaints about it was that it had not made a move “against the House of Lords.” Suffice it to say, in other words, that the British tradition regarding the idea of a single legislative body is at least as strong as that of the French.
Support for the idea of a single legislative house, called unicameralism, is however not limited to European sources. For example, the French revolutionary leader, the Marquis de Condorcet, only began expressing support for the concept after meeting Benjamin Franklin in 1776—the Philadelphian having recently arrived in Paris from an American state, Pennsylvania, best-known for its single-house legislature. (A result of 1701’s Charter of Privileges.) Franklin himself contributed to the literature surrounding this debate by introducing what he called “the famous political Fable of the Snake, with two Heads and one Body,” in which the said thirsty Snake, like Buridan’s Ass, cannot decide which way to proceed towards water—and hence dies of dehydration. Franklin’s concerns were later taken up, a century and half later, by the Nebraskan George Norris—ironically, a member of the U.S. Senate—who criss-crossed his state in the summer of 1934 (famously wearing out two sets of tires in the process) campaigning for the cause of unicameralism. Norris’ side won, and today Nebraska’s laws are passed by a single legislative house.
Lately, however, the action has swung back across the Atlantic: both Britain and Italy have sought to reform, if not abolish, their upper houses. In 1999, the Parliament of Great Britain passed the House of Lords Act, which ended a tradition that had lasted nearly a thousand years: the hereditary right of the aristocracy to sit in that house. More recently, Italian prime minister Matteo Renzi called “for eliminating the Italian Senate,” as Alexander Stille put it in The New Yorker, which the Italian leader claimed—much as Norris had claimed—that doing so would “reduc[e] the cost of the political class and mak[e] its system more functional.” That proved, it seems, a bridge too far for many Italians, who forced Renzi out of office in 2016; similarly, despite the withering scorn of Orwell (who could be quite withering), the House of Lords has not been altogether abolished.
Nevertheless, American professor of political science James Garner observed so early as 1910, citing the example of Canadian provincial legislatures, that among “English speaking people the tendency has been away from two chambers of equal rank for nearly two hundred years”—and the latest information indicates the same tendency at work worldwide. According to the Inter-Parliamentary Union—a kind of trade organization for legislatures—there are for instance currently 116 unicameral legislatures in the world, compared with 77 bicameral ones. That represents a change even from 2014, when there were 3 less unicameral ones and 2 more bicameral ones, according to a 2015 report by Betty Drexage for the Dutch government. Globally, in other words, bicameralism appears to be on the defensive and unicameralism on the rise—for reasons, I would suggest, that have much to do with widespread adoption of a perspective closer to Dawkins’ than to Eagleton’s.
Within the English-speaking world, however—and in particular within the United States—it is in fact Eagleton’s position that appears ascendent. Eagleton’s dualism is, after all, institutionally a far more useful doctrine for the disciplines known, in the United States, as “the humanities”: as the advertisers know, product differentiation is a requirement for success in any market. Yet as the former director of the American National Humanities Center, Geoffrey Galt Harpham, has remarked, the humanities are “truly native only to the United States”—which implies that the dualist conception of knowledge that depicts the sciences as opposed to something called “the humanities” is one that is merely contingent, not a necessary part of reality. Therefore, Terry Eagleton, and other scholars in those disciplines, may advertise themselves as on the side of “the people,” but the real history of the world may differ—which is to say, I suppose, that somebody’s delusional, all right.
It just may not be Richard Dawkins.
