A music appreciation course

May 29, 2023

Over the past 8 or 9 months I’ve been running a weekly “music appreciation” class for a group of homeschooled kids in our neighbourhood. I’ve typically had 10 or 15 of them in our living room for the better part of an hour to talk about and listen to music. I think the oldest of them was about 14, and the youngest maybe 8 or 9.

As we are winding up for the year, I thought I’d post a summary of what we covered. Some of these kids play instruments, and a few sing in parish choirs, so they have some familiarity with our musical tradition, but for the most part this music was new to them.

Rather than just having them listen, I curated a set of live concert recordings (from YouTube, which has a vast collection of such) so that we could listen and watch. This, I thought, would help them to appreciate how, for instance, an orchestra works together to produce music, and how challenging some of the music is to play, and, also, I thought it would be likely to hold their attention better than audio-only would. And in this I think I was right.

The choice of music was guided by a few considerations. My aim was to give them a sense of the arc of development of Western music (so we proceeded chronologically), and also to expose them to the variety of music in our tradition, so we listened to orchestral music, and chamber music, and music for single instruments, and opera, and choral music. I wanted to let them hear acknowledged masterpieces. I sometimes chose pieces in order to highlight particular instruments, or to illustrate certain musical forms. I wanted a good quality video of a good performance. (Indeed, sometimes I chose a fairly obscure piece just because there was a terrific performance to watch.)  Of course the music had to fit into the time we had available, so sometimes we heard entire pieces, and sometimes we heard excerpts. But most of all I wanted them to enjoy the experience, so I tried to choose wonderful music that would delight them.

Anyway, it has been a great experience for me, and I hope for them as well. Here’s a skeleton sketch of how it looked:

Books briefly noted: plays

May 19, 2023

Quick notes today on a few plays I have read recently.

**

The Acharnians
Aristophanes
Translated from the Greek by Paul Roche
(New American, 2005) [425 BC]
62 p.

The Acharnians was not Aristophanes’ first comedy, but it is the earliest that we have. It won first prize at the Lenaean Festival in 425 BC, when the playwright was about twenty years old. It helps to understand the context: Athens was a half-dozen years into the war against Sparta, and each summer the Spartan army was marching into Attica and attempting to destroy the crops; people fled to the safety of the walls of Athens. In the play, Dikaiopolis, grown weary of the war and its hardships, and frustrated with the hawkishness of the Athenian Council, decides to make a private peace with the Spartans, just for himself and his family, so that he can open up trade in the marketplace and have nice things again. A pretty good premise, but Aristophanian humour must be hard to capture in translation, because I had little more enjoyment from this play than I’ve had with other of his plays in the past: mildly amusing, yes, but not much more. The play felt unstructured, the verse awkward, and I had a hard time imagining how the jokes would land successfully.

***

The Changeling
Thomas Middleton
and William Rowley

(Oxford, 2007) [1622]
50 p.

This play, a collaborative venture between Thomas Middleton and William Rowley, has earned a good reputation, with a relatively large number of revivals and adaptations in its wake. The story is about a woman who finds herself at the center of a love quadrangle: she is promised in marriage to a man she does not love, beset by advances from a man she despises, and unable to pursue marriage with the man she does love, and who loves her in return.

To untie this knot, she hits on a plan which she hopes will rid her of both unwanted suitors in one fell swoop. But, this being a Jacobean tragedy, the plan goes disastrously awry. It is worth noting, however, that it doesn’t go as totally awry as it might have; in time bodies do litter the stage, but not everyone’s body.

It seems a good play, but it didn’t appeal to me as some other of Middleton’s plays have. I appreciated the set-up, and the central characters are interesting, but I found some of the plot elements, such as a peculiar elixir to be administered to suspect wives by doubtful husbands, a tad bizarre, and a confusing subplot involving an entirely different cast of characters played for me as mere distraction. Maybe I just failed to grasp what Middleton and Rowley were up to. I confess I don’t understand the play’s title.

The Purgatory of St. Patrick
Pedro Calderón de la Barca
Translated from the Spanish by Denis Florence MacCarthy
(Henry S. King & Co., 1873) [before 1635]

Since medieval times there has been a pilgrimage site in the north of Ireland near Lough Derg called St Patrick’s Purgatory. I picked up this play thinking it would be about the site, and I was right. The pilgrimage site became such because it was believed that St Patrick revealed, on that spot, a cave through which one could pass to Purgatory. The play tells the story of how this came about.

In the first Act, Patrick and a criminal called Luis Enius come to Ireland, the former as a slave and the latter as a fugitive. The Irish people are pagans. In the second Act, Patrick performs miracles and reveals the entrance to Purgatory. In the last Act, many years later, Patrick has died and Luis, passing into Purgatory, goes on a Dante-esque journey through the afterlife that results in his conversion.

The robust Catholic piety of the play was pleasing to me; we English speakers are just not used to this in our theatre, but this Spanish playwright, at least, had no compunction about foregrounding religious matters on his stage. The third Act odyssey through the afterlife is quite imaginatively done.

That said, the play is not very good; certainly it is much inferior to the other of Calderón’s plays that I have read recently. The first Act is thrown off balance by a pair of monstrously oversized monologues from Patrick and Luis. The action of the play develops in a haphazard manner, without a clear logic and without character motivation. The characters themselves are thin. The whole thing seemed to lurch from scene to scene without much at stake.

As to the verse, it’s hard for me to say. The 1873 translation — the only one, so far, into English, I believe — makes a valiant effort to be true to Calderón’s metre and rhyme, but I didn’t find much music in it. Late in the play one of the characters exclaims, “Oh! who that’s not insane / Will enter Patrick’s Purgatory again?”, and while I wouldn’t pose the question in just that way, my answer is very likely, and regrettably, “Not I”.

Maritain: Art and Scholasticism

May 11, 2023

Art and Scholasticism
Jacques Maritain
(Scribner’s, 1930) [1923]
177 p.

Beauty is the word that shall be our first. Beauty is the last thing which the thinking intellect dares to approach, since only it dances as an uncontained splendour around the double constellation of the true and the good and their inseparable relation to one another. Beauty is the disinterested one, without which the ancient world refused to understand itself, a word which both imperceptibly and yet unmistakably has bid farewell to our new world…

— von Balthasar, The Glory of the Lord: a Theological Aesthetics, Vol. 1

Not many philosophers, I think, have written convincingly and insightfully about aesthetics. As Balthasar says above, it’s a slippery topic that seems to resist analysis. The ancient world may, as he says, have refused to understand itself apart from beauty, but nonetheless medieval philosophers said more, and more systematically, about truth and goodness. In this book Jacques Maritain gathers up the stray statements about beauty and art to be found in the scholastics, and especially in the writings of Thomas Aquinas, and puts them into order, thereby sketching for us a basic framework for thinking about art, the making of art, and the place of beauty and morality in artistic appreciation.

**

Art has to do with the practical, rather than the speculative, order. It is not focused simply on truth, as is (say) logic or theology. The practical order has to do with doing and making; doing concerns prudence and ethics and the good of the person acting, but making has to do with the good of the thing made. Art has to do with making.

Art, here, is being treated in its widest connotation: something made. It might be a stool or a Missa Solemnis. The particular distinction that makes something a “fine art” will be discussed below.

Because art as such aims at the excellence of the thing made, it goes astray if it aims at anything else. It may evoke emotion, but it must not aim at doing so. It may earn the artist a living, but that cannot be its purpose. It may give pleasure, but that cannot be its primary aim. It may edify or instruct, but its artistic excellence does not consist in this. It may effect change in the world, but it cannot be made for that reason. Just as a scientist’s intention is only to present his audience with what is true, so the artist must aim only at what is well-made.

Maritain has much to say about the qualities and characteristics of an artist. Following the scholastics, he argues that an artist is someone who possesses the habitus of art. This habitus is a somewhat difficult word; it is not “habit” in the modern sense of something rote and unthinking, for habitus involves intellect and will. It is, he says, a characteristic of the soul that enables a person to do a thing readily and naturally. It is a stable disposition that perfects a faculty of the one possessing it; the habitus of art enables the person to make art naturally, as a capacity of soul. A habitus is a capacity that is realized in a person. The habitus of art involves the intellect inasmuch as the formal element in all art is ruled by the intellect, for art as such is the act of investing matter with form, of imprinting an idea onto matter. A master carpenter is one who knows how to make things from wood. He has a sense of what to do in a given situation, what will work, what will lead to an excellent result. He has the habitus of art as it pertains to woodworking. A mathematician has the habitus of mathematics; he has a sense of it, he knows where he is, he slips into the world of his abstractions as easily as a seal into the water. I’m sure you know people like this, who have a habitus of some kind.

Some habitus can be used for good or for ill, but a habitus that can only do good is what we call a virtue. Justice and courage are virtues. Art, as Maritain means it, is such a habitus. To have it means to have the capacity to make good things.

Art is the investment of matter with form, and as such is addressed to the intellect. Even so, art does not give knowledge but delight (although greater knowledge increases the possibility of delight, which is why there is such a thing as educated or well-formed taste and judgment). Art does not give us an “idea”; a work of art cannot be boiled down to “the point” or “the lesson”. A work of art is what it is precisely because that is the form in which it can be expressed; it cannot be expressed as an idea. “It expresses what our ideas cannot signify.” Art is the one realm in which we know things intuitively and immediately, as angels do, though we know them through our senses rather than (as with angels) abstractly.

God Himself is a maker, and so an artist, and possesses the virtue of art preeminently. God’s love is the cause of beauty, whereas for us beauty is the cause of love. Because beauty involves perception of form, it can be seen more readily by those who know that things have a Creator.

The scholastics did not stress the distinction between the fine arts and other kinds of making. (They distinguished liberal from servile arts, but the division is not the same.) Nonetheless, the distinction between fine arts and other arts is present in their thought: an art is a fine art when it is ordered to beauty as its end, rather than to some other purpose. A shoemaker’s primary purpose is to make good shoes, and making handsome good shoes is part of that purpose but not the whole of it. A chef’s primary purpose is to make an excellent dish, drawing on the many ways in which a dish can be excellent, and the dish may be beautiful, but that is not its main purpose. But a composer aims to make something beautiful per se. That is the source and summit of his labours. What he makes has no other purpose. Likewise for the other fine arts: what sets them apart is that their beauty is the point of their being.

Apprehension of beauty involves perception of form. Maritain argues that we perceive beauty by way of our senses (and specifically sight and hearing). At the same time he defines beauty, following the scholastics, as “being considered as delighting . . . an intellectual nature”. So when we behold a work of art we are integrating our sensory and intellectual capacities in a particularly pure way.

Note well that “beauty” is a multifaceted thing. To say that the fine arts aim at beauty as their end isn’t to confine them to any narrow or conventional standard of beauty. Maritain stresses that “there is always an infinity of ways of being a beautiful work”. We often hear it said that “beauty is in the eye of the beholder”, meaning that it is relative. Maritain agrees that it is relative in some ways, but not with respect to the subject (as is the usual meaning of the phrase in our time). Rather, he argues that beauty is truly apprehended by the subject, but that beauty is relative to the end and conception of the thing made. That is, how it is beautiful depends on its form and purpose. The last string quartet of Shostakovich isn’t beautiful in a conventional sense; it’s thorny and difficult and even, by some standards, ugly, but it realizes its form — it is proportionate, it is intelligible, it has an organic unity — and it exists for no other reason than to do just that. To say that all works of fine art are distinguished by having beauty as their end is not to narrow their range of expression, but it is to give them all a certain dignity.

**

Maritain stresses numerous times that for an artist, the good of the thing being made is the highest concern: excellence above all, a full realization of the conception of the work. The artist cannot be distracted by any other consideration without the work suffering. But this raises the question of how art and morality are related, because the moral excellence of a work of art is distinct, it seems, from its specifically artistic excellence.

In response to this question Maritain makes some important distinctions. Although it is true that the artist as an artist aims only at the good of the work made, this cannot be his highest aim as a human person without leading to idolatry. The artist, as a person, must work for something higher than artistic excellence, and it is here, Maritain thinks, that morality enters the picture, for although the artist as an artist is blind to it, the artist as a human person cannot be:

“Art has no right against God. There is no good opposed to God or the ultimate Good of human life. Art in its own domain is sovereign like wisdom; through its object it is subordinate neither to wisdom nor to prudence nor to any other virtue. But by the subject in which it exists, by man and in man it is subordinate — extrinsically subordinate — to the good of the subject; insofar as it finds itself in man and insofar as the liberty of man makes use of it, it is subordinate to the end of man and to the human virtues.”

Since every human artist is a human being, art is therefore always subject to moral evaluation. As we know it must be. Art may be metaphysically superior to prudence, but in the realm of human action prudence sits in judgment. Beauty and morality are both always relevant to anything made by an artist.

Moral evaluation nonetheless poses certain hazards for art. Art that is too deferential to moral expectations can fail on that account by failing to put the artistic good first. Self-consciously pious religious art and politically correct art are vulnerable to this trap. In another way, even works of great artistic excellence can be unwisely spurned because subjected to the judgment of a narrow, puritanical moral view. The seemingly wholesale rejection of our artistic inheritance from “dead, white males” is the most obvious example of this in our own times.

**

Given the emphasis Maritain puts on the (conditional) autonomy of art, it’s interesting to read his views on religious art, and specifically (since he was a Christian) on Christian art. This is a realm in which, on the one hand, art may be tempted away from its proper good by allowing pious considerations to overrule artistic ones, yet, on the other hand, it is a realm in which the “foreign” good is actually higher than the artistic, and so, perhaps, able to elevate the art even if it, at some level, interferes with its purity.

Maritain makes a distinction between Christian art and religious art. The first is, for him, any art made by a Christian regardless of its content, whereas the second has to do with art intended for an “officially” religious purpose, such as liturgical art. As to the former — “Christian art” — he argues that it refers to no style or technique, but simply to an implicit or latent expression of a Christian view of things, no matter the immediate subject. “Everything belongs to it, the sacred as well as the profane. It is at home wherever the ingenuity and the joy of man extend.” Christianity affects the Christian’s experience of the world in a way that is distinctive and affects his art, for it gives him “simplicity, the peace of awe and of love, [and] the innocence which renders matter docile to men and fraternal”. He finds Christian art wherever a Christian makes art truly and honestly. Like Augustine whose moral counsel was “Love God above all things, and then do as you will”, Maritain’s advice to Christian artists is, “Be a Christian, and simply try to make a beautiful work.”

Religious art, on the other hand, serves a solemn and, at some level, official purpose within a religious tradition. Maritain lays out a few requirements that he thinks such art must satisfy. First, it must be comprehensible by the other adherents of the tradition. The comprehension and appreciation need not be universal, of course, since, as he says, “there are an infinite number of Christians with bad taste”, but it should present itself as intelligible and appropriate by some reasonable standard. Second, it must be well-made, proper, and honest; nothing shabby or substandard should be acceptable in worship. Third, it must be dependent on and deferential to theology; it must be vigilant against doctrinal distortions and against sowing discord or confusion among the faithful. Finally, it should be religious in expression, touched in some way by piety and devotion.

With these criteria in mind, it’s interesting to think of some test cases. The heritage of Gregorian chant, for instance, would be an archetypal example of religious art. We could say with confidence, I think, that Michelangelo’s Last Judgment would qualify. What about one of Vaughan Williams’ hymns? I think so, but is there some friction on the fourth criterion because Vaughan Williams was an agnostic? I hope not. In the last few centuries much Catholic art has fallen under the baleful influence of kitsch, and so fails on the criterion of being well-made, perhaps. (Think of all those images of Divine Mercy.) The dismal parade of folksy music that has displaced the chant since Vatican II fails resoundingly. Maritain thought, in his time, that he could discern “the regermination of a truly Christian art,” and he — and this book — were an influence on, inter alia, Stravinsky, Claudel, and other major artists, but that regermination seems to have fallen afoul of one or more of the hazards outlined in the parable of the sower. Not that we are entirely without hope.

**

It is a stimulating book, rich in ideas. Although it feels in some respects a little “academic” as he rolls out distinctions between speculative and practical, prudential and artistic, servile and liberal, and so on, I suppose a book about scholastics should be expected to be academic, if etymologists are onto something. I appreciated the wide net; many of his statements about art apply as much to the carpenter as the composer. There is a healthy appreciation that art can serve practical purposes, or, put the other way around, that useful, everyday things can, and should, nonetheless be works of art.

The doctrine that fine arts are those that aim at beauty as their primary end has something to it, but it is important, I think, that it be coupled with an expansive idea of beauty; Maritain is careful about this, but it’s the kind of point that might be easily forgotten or oversimplified. I’m also curious about what doesn’t qualify as a fine art under this definition. I wonder, for instance, if narrative arts, like storytelling (on paper or film) are aiming at beauty in the relevant sense. Maritain doesn’t seem to think much of literature, saying at one point that “Literature puts on the work the grimace of personality.. Literature is to art as self-conceit is to the moral life,” which strikes me as harsh. But then he turns around and says that, “Poetry…is to art what grace is to the moral life,” so the written word isn’t entirely excluded from the tent.

Also worthwhile is the framework for thinking about art and morality. We understand that the proper good of a work of art is not a moral one, but also that art cannot be somehow outside the realm of moral evaluation. The series of distinctions he makes provides a way to retain both sides of the issue and understand how they relate.

The book was, I believe, influential in the early twentieth century. Wikipedia cites a scholar who claims the book “was a key text that guided the work of writers such as Allen Tate, Caroline Gordon, Sally and Robert Fitzgerald, Francois Mauriac, Thomas Merton, John Howard Griffin, Flannery O’Connor and T.S. Eliot.” A good list. It also does the valuable service of pulling together St. Thomas’ thoughts on aesthetics and putting them in some kind of order. Still, one wishes that the master might have done it himself!

[Art and love]
The artist has to love, he has to love what he is making, so that his virtue may truly be, in Saint Augustine’s words, ordo amoris, so that beauty may become connatural to him… This undeviating love is the supreme rule.

[On Satie]
Never any sorcery, repetitions [what, never?!? — Ed.], suspicious caresses, fevers, or miasmas. Never does Satie ‘stir the pool’. It is the poetry of childhood relived by a master technician.

[Intelligence and reality]
The intellect…seizes being and draws it into itself — it eats being and drinks being — so as “itself to become, in a certain fashion, all things. […] Like a stag at the gushing spring, intelligence has nothing to do but drink; it drinks the clarity of being.

[The medieval period]
Matchless epoch, in which an ingenuous people was formed in beauty without even realizing it.

Fisher: What is Dark Matter?

May 8, 2023

What is Dark Matter?
Peter Fisher
(Princeton, 2022)
179 p.

As Sherlock Holmes might have said, it pays to make careful observations. Astrophysicists and cosmologists would seem to be working with a significant handicap — the object of their study cannot be reproduced in the laboratory, cannot be touched, cannot be experimented upon. It can only be looked at. Nevertheless, over the past century they have made very careful observations of the heavens, and have delivered a whole series of startling discoveries: there are black holes, there are neutron stars, there are supernovas, the universe had a beginning!

But perhaps the strangest and most unexpected of their findings has been that the stuff we observe in the universe accounts for only a small fraction — about 5% — of the stuff that exists out there. The rest, which we don’t see, astrophysicists call “dark”, and it comes in two species: dark energy, and dark matter. The latter, which is believed to account for about 25% of the mass of the stuff in the universe, is the subject of this book.

The reason we think there is any dark matter is that the gravitational effects we observe are not consistent with the amount of matter we observe, assuming the correctness of Newtonian gravity. Fisher outlines the main lines of evidence: galactic rotation curves (stars in galaxies rotate about the center faster than we expect, and extra gravitating matter is needed to hold the galaxy together), gravitational dynamics of galactic clusters, dynamics of galaxy formation, gravitational lensing, the history of the Bullet Cluster, and the fluctuations of the cosmic microwave background. All point to the existence of something that has gravitational influence but is unseen. The picture that emerges is that galaxies seem to be “shadowed” by a sphere of material that is substantially (ie. 3-4x) greater in extent than the visible matter. It is not dense — at our location in the Milky Way, for example, the expectation is that dark matter contributes the equivalent of a few proton masses per cubic centimeter — but there is so much of it that it makes a difference on the large scale.

The inference to dark matter depends on our trust in the correctness of Newtonian gravity on large distance scales. When I was in graduate school I was friendly toward the idea that modifications to gravity could account for the observations without the need to introduce dark matter. Fisher argues that this possibility has been almost entirely excluded in the intervening years. It seems we’re stuck with dark matter.

***

So what is it? In the early days people thought it might be ordinary matter that just happens to be non-luminous: failed stars, white dwarfs, planetary bodies, interstellar gas. When the neutrino was found to have a small mass it was a candidate for dark matter. Black holes made by earlier generations of supernovae were candidates. But, as Fisher describes, these possibilities have, one by one, been eliminated. Dark matter is not anything we already know about. It’s something new.

Today there are, according to Fisher, three main candidates for dark matter. The first is that it might be primordial black holes; these are small black holes that might have been formed in the very early universe and have not yet radiated away. Their mass range is bounded by data from both below and above. They would be sub-microscopic, having masses in the vicinity of a large asteroid, and would be extremely difficult to detect by any known method. We don’t know if such black holes exist.

A second candidate is what physicists call a WIMP — a weakly interacting massive particle. It’s a pretty generic name, but actually we can say quite a lot about what properties it would need to have, and part of the joy of reading this book is to learn of the very creative and heroically sensitive experimental apparatus’ that have been designed and built to detect them. WIMP detectors are trying to measure recoil of atomic nuclei in the apparatus due to collision with a WIMP. Perhaps my favourite of these experiments is DAMA/LIBRA, which attempts to measure the dark matter “wind” that we would experience if the earth moved through a background of dark matter. Because the earth reverses its direction of motion every six months (during its orbit around the sun), they look for a seasonal variation in their signal, and, to my astonishment, they observe one! I like this experiment not only because it shows a signal (which none of the others have), but because it is so reminiscent of the classic Michelson-Morley interferometer experiment in the late nineteenth-century. It’s quite beautiful. But physicists are generally cautious in interpreting data, and until another experiment can reproduce their findings, there is still a possibility that their signal is due to seasonal systematic errors caused, for instance, by temperature changes in their electronics, or some other hard to identify cause. WIMP searches have been able to put upper limits on the possible masses and interaction strengths of WIMPS with ordinary matter.

The third option for dark matter is a new kind of particle called an axion. Axions were actually invented for another purpose — to account for a peculiar observed feature of our theory of quantum chromodynamics — but it was later realized that, if they exist, they could be dark matter. They would have to have a mass roughly a million billion times less than a proton. Again, a set of fascinating and creative experiments, which Fisher describes, have been done to look for axions, and the lack of success has put upper limits on their masses and interaction strengths with ordinary matter.

Whatever dark matter is, we now know that its probability of interacting with ordinary matter is extremely low. Neutrinos used to be the extreme example of a weakly interacting particle, but the interaction strength of dark matter must be many orders of magnitude smaller. Indeed, the interaction strength is so small that a depressing possibility broods over all efforts to search for dark matter: the interaction strength with ordinary matter might be exactly zero. In that case — the so-called “nightmare scenario” — we will never be able to build an experiment to detect it, and our only hope for studying it would be through its gravitational effects.

I hadn’t been following developments in dark matter research since I finished graduate school, and this was an excellent way to catch up. The book is written in a non-technical, no-nonsense style, and I found it accessible and informative. It’s a little discouraging for me to learn that dark matter actually does, it seems, exist, as I never much liked the idea, but, on the other hand, it was a pleasure to read about the sometimes incredible ingenuity of experimentalists, who are undaunted by even the most formidable technical challenges. An edifying read.

Nero Wolfe, contemplative

May 4, 2023

In his little book Take and Read, Eugene Peterson proposes a surprising but, on reflection, intriguing interpretation of the character of Nero Wolfe in Rex Stout’s novels. I’ve long loved Wolfe as a character — he is, by a good margin, my favourite literary detective — and this way of thinking about him, while perhaps a little idiosyncratic, has enriched my appreciation. I cite Peterson’s comments in their entirety, recommending, at the same time, the book from which they come.

***

Nero Wolfe, the fat detective featured in the numerous Rex Stout murder mysteries, is not a clergyman, but for 30 years I have amused myself and some of my friends by reading him as a parable of the Christian contemplative presence in the world. The popular imagination, told by contemporaneity, sees nothing in the Nero Wolfe stories but detection. But Stout has written a body of work every bit as theologically perspicuous as Swift with the result that he hits the bestseller list as a clever and resourceful detective novelist. To his financial benefit, of course, but still, for a serious writer to be misunderstood so completely must be humiliating no matter what the bank balance. But once the theological intent is suggested, the barest sleuthing quickly discerns Nero Wolfe as a type of the Church’s presence in the world.

The most evident thing about him, his body, provides an analogue to the Church. His vast bulk is evidence of his “weight,“ recalling the etymology of the biblical “glory.“ More than anything else he’s there, visibly. He must be reckoned with. He is corpulent or nothing. And the church is the body of Christ.

Along with an insistence on bodily presence there is a corresponding observation that there is nothing attractive about that body. His body is subject to calumny and jokes. His genius is in his mind and his style. He does not follow on before customers, nor seek “contacts“ (a word, incidentally, that he would never use. He once was found ripping apart a dictionary, page by page, and burning it because it legitimized “contact“ as a transitive verb).

Wolfe will not leave his house on business, that is, accommodate himself to the world’s needs. He is a centre around which the action revolves, the centre of the wheel and meditation, not a centre of power or activity. He provides a paradigm for Christian spirituality that, while reticent and reserved, is there in vast presence when needed. He has no need for advertising techniques or public relations programs. He is there and needed because there is something wrong in the world (murder and other criminal extremes). He models a contemplative life which is not here to be loved, not designed to inspire affection. It is massive, central, important – a genius, in fact. But you don’t have to like it.

In all this there is an implied criticism of a Church that has succumbed to public relations agents who have mounted Christian pulpits to make the church attractive – to personalize her, to sentimentalize her. Wolfe, as Christian ministry, levels a rebuke against that kind of thing. It follows that there is disdain for defensive explanations – a Barthian avoidance of “apologetics“ to a world that seeks assurance of its reliability and effectiveness. To that kind of inquiry he says: “I can give you my word, but I know what it’s worth and you don’t.“ The spiritual life is cheapened when it tries to defend itself or make itself acceptable in terms the world can understand.

Early Tom Stoppard plays

May 1, 2023

A few months ago I was at a second-hand book sale, and, rummaging around in a box under one of the tables, I discovered a large collection of Tom Stoppard’s plays in, mostly, first edition Faber & Faber paperbacks. Stoppard is one of the few modern playwrights whom I admire — and, to be fair, one of the few whom I know about — but most of the plays I discovered in that box were unknown to me. Over the next few months I plan to read through them, posting occasional notes here.

Not all of his plays were in that box, so, because I’m the type that likes to be orderly and systematic, today I’m backing up to the very beginning, or as close as I know how to get, and reading a few plays that I’ve tracked down in the meantime.

The Dissolution of Dominic Boot
[1964]

This brief (quarter-hour) radio play was one of the first things Tom Stoppard did; it played on BBC radio a few years before he splashed into the theatre scene with Rosencrantz and Guildenstern are Dead. It’s a fun little piece in which we follow a young man, hard up for cash, who rides a taxi from bank to bank, and then from friend to friend, trying to gather together enough money to . . . pay for the taxi. The more doors slam in his face, the higher his fare gets, until, at play’s end, he’s bartering away his last belongings to the cabby himself. It’s well-sculpted, riding a natural slope of escalation as the debt hole deepens with each passing mile. I read the play, and also listened to the archival BBC recording from 1964.

‘M’ is for Moon Amongst Other Things
[1964]

Another short radio play originally broadcast on the BBC in 1964, this one is more sober and poignant than The Dissolution of Dominic Boot, though not without an undercurrent of humour. A middle-aged couple, one contemplating her fast-approaching forty-second-and-a-half birthday, the other wrapped up in his newspaper and worries about work, turn on the evening news to hear that Marilyn Monroe has committed suicide, which news provokes in her more anxiety about mortality and in him strange expressions of affection for Marilyn, all the more inappropriate inasmuch as he seems unable to give his wife adequate attention and love. Some good comedy about Catholics eating fish on Friday, alas!

*

A Separate Peace
[1966]

In the middle of the night a middle-aged man, amiable and apparently perfectly healthy, steps into a hospital ward and announces that he intends to stay. He won’t say where he comes from, but he has a large suitcase full of cash to pay for his keep. The staff, naturally, doesn’t know what to do with him. Beds are available; why mayn’t a healthy man occupy one? He likes the regularity of the schedule; he likes being able to stay in bed without feeling guilty about it — where else but in a hospital?

The point is not breakfast in bed, but breakfast in bed without guilt — if you’re not ill. Lunch in bed is more difficult, even for the rich. It’s not any more expensive, but the disapproval is harder to ignore. To stay in bed for tea is almost impossible in decent society, and not to get up at all would probably bring in the authorities. But in a hospital it’s not only understood — it’s expected. That’s the beauty of it.

Such is the setup for this short play, which I believe was written for television, and was broadcast on the BBC in August 1966, the same month in which Rosencrantz premiered. It’s an enjoyable little piece — I’d estimate that it probably ran about half an hour in performance? — that might, given the premise, have become an absurdist comedy à la Beckett, or a sober meditation à la Mann, but instead became a winsome, recognizably Stoppardian, marriage of wit and human warmth.

To my knowledge the original television broadcast has not been archived, or at least is not available to the public, but the play has been reprinted in Volume 3 of Faber and Faber’s edition of Stoppard’s complete plays.
