Chapter 6 — The Ethics at the Edge

"A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise." — Aldo Leopold, A Sand County Almanac (1949)

T his volume has spent five chapters in praise of curiosity. It has followed Darwin around the anchorages of the Beagle as he ate his own specimens, raised a glass to the zoophagists who made a near-doctrine of tasting the animal kingdom, sat down with a straight face to the fermented shark and the living cheese, argued that the insect is merely livestock the West has not yet forgiven, and shown that disgust itself is a costume the culture sews and the child grows into. Curiosity has been the engine throughout, and this chapter has no intention of switching it off. But an engine with no brakes is not free; it is only doomed, and it takes its passengers down with it. The previous chapter closed by dismantling the oldest brake the eater owned — the settled conviction that certain creatures simply are not food — and the honest consequence of that argument is that a replacement must now be built by hand, in daylight, on purpose. This chapter builds it. It is the one place in the book where the naturalist stops asking may I taste it? and asks instead what does my tasting it cost?, and where, for the first time, some of the answers are simply no.

That word deserves its full weight at the outset, because everything else here depends on it. The line this chapter draws is not a matter of taste, and it is not offered as one opinion among several a broad-minded reader might weigh over the port. Curiosity is a virtue only for as long as it is answerable to something larger than itself. Where the price of a food is paid by the eater alone — his squeamishness, his comfort, his inherited sense of the proper — the palate should be as open as this book has spent five chapters arguing. But where the price is paid by a species that cannot afford it, or by an animal made to suffer for no better reason than that its suffering is a novelty, curiosity has reached the edge of its licence. There the answer is not "proceed, with an interesting frisson of guilt." There the answer is "stop."

The Debt Comes Due

The bill this chapter has to settle was run up, in no small part, by the very history the earlier chapters admired. Return to Darwin's Galápagos. The giant tortoises that Chapter One introduced as the larder of the sailing age were, for the better part of three centuries, precisely that: a living tinned food that could be stacked in a ship's hold and would survive for months without water or fodder, to be killed for fresh meat and oil an ocean away from land. Buccaneers began the work and the whalers and sealers finished it, and the best estimates put the total taken across the era at around two hundred thousand animals. Several of the archipelago's dozen-odd forms were driven out of existence altogether; the Pinta Island tortoise dwindled to a single male, discovered in 1971 and known for the rest of his long life as Lonesome George, whose death on the twenty-fourth of June 2012 closed the account on his lineage in front of the world's cameras. The tortoise that provisioned the age of sail is now, every surviving kind of it, listed on Appendix I of the Convention on International Trade in Endangered Species — the strictest tier there is, under which commercial trade is forbidden outright. The larder became a lesson, and the lesson has the force of law.

The whales tell a larger and grimmer version of the same story. Industrial whaling killed on the order of three million great whales in the twentieth century, a slaughter without precedent in the history of the human appetite for a single kind of animal. The blue whale, the largest creature that has ever lived, was very nearly the most complete casualty of it: something like three hundred and fifty thousand were killed, and in the Southern Hemisphere the population was cut by more than ninety-nine per cent, to a remnant of a few thousand from an original two or three hundred thousand. It was only in 1982 that the International Whaling Commission voted for a worldwide moratorium on commercial whaling — the vote was twenty-five to seven — to take effect from the 1986 season; every great whale regulated by the Commission is now also listed on CITES Appendix I. The ban held, though never quite universally: Norway lodged a formal objection and hunts minke whales to this day, and Japan, after decades of whaling it defended as scientific, withdrew from the Commission altogether in 2019 to resume openly commercial hunts within its own waters, while Iceland's once-defiant fishery has dwindled almost to nothing — exceptions that honesty requires naming even while insisting they remain exceptions and not the rule. The moratorium is rightly counted among the leading conservation victories of the last century, and it is worth pausing on why. It worked. It is the hinge on which this whole chapter turns, away from lament and toward something sterner and more useful.

For the modern reality of these animals is not only a catalogue of loss; it is, increasingly, a demonstration that restraint repays. Three instruments do the real work, and the curious eater should know their names, because between them they draw most of the hard lines this chapter is concerned with. CITES, in force since 1975 and binding on more than a hundred and eighty member states, governs what may cross a border: its Appendix I bans commercial trade in the most endangered species, its Appendix II regulates trade in those that would be threatened without control, and its listings are debated and voted every few years at a Conference of the Parties, where a two-thirds majority can move a creature from the second tier to the first. The IUCN Red List, maintained by the International Union for Conservation of Nature, is the world's ledger of how near each species stands to the edge, ranking every assessed creature up a grim ladder — Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild, and at the top of the climb simply Extinct — so that a single reclassification, up or down, is a measured verdict on whether a species is falling toward that summit or being pulled back from it. And beneath both sit national laws — the European Union's Birds Directive, a country's fisheries and wildlife acts — which turn the international verdict into a fine or a prosecution. These are not bureaucratic footnotes to a gastronome's pleasure. They are the built structure that stands where the eater's old instinct used to, and they have teeth.

The instruments are not beyond argument, and an honest chapter should say so. A serious school of conservation holds that a blanket ban is not always the surest protection — that a regulated, legal, sustainable harvest can give a species a cash value that pays for its own survival, as the ranching of the Nile crocodile and the shearing of wild vicuña for their fleece have arguably done, turning a creature worth more dead into one worth more alive and guarded. Where a population is genuinely abundant, that logic has real force. But it runs out precisely where this chapter lives, at the edge, for a species already near collapse cannot bear the gamble that a legal trade will be used to launder an illegal one, and the burden of proof must sit with the harvest and never with the animal. For the truly endangered the precautionary floor holds: when in honest doubt, the answer is still stop.

Consider what those teeth have bought. Turtle soup, the green glory of Georgian and Victorian banquets, was assembled from the green sea turtle, Chelonia mydas, which English sailors first took from the Caribbean in the seventeenth century as shipboard protein and which had become, by the 1750s, a fixture of civic feasts and a byword for luxury; the trade helped press the species toward collapse. The green turtle was listed as Endangered for more than forty years and protected under CITES Appendix I — and in October 2025, on the strength of that long protection, the IUCN reassessed it as Least Concern, its monitored nesting numbers up by roughly a quarter. The Atlantic bluefin tuna, whose bluefin kin the sushi boom hunted so hard that its price became a headline — a single fish sold at Tokyo's Toyosu market in 2019 for more than three million dollars — was likewise moved from Endangered to Least Concern in 2021 after two decades of enforced quotas under the international commission that manages the fishery; its recovered eastern stock is the proof of concept, even as its western stock and the still-Endangered southern bluefin are the reminder that the work is uneven and unfinished. This is the honest modern reality the volume promised to set beside every historical relish: the tortoise, the whale, the turtle and the tuna were all eaten toward the edge, and where we chose to stop, several of them have begun, slowly, to come back.

Where we have not chosen to stop, the wound stays open, and the curious palate should recognise these as the places it does not go. The fin of the shark, sliced off to thicken a celebratory soup, still costs the lives of an estimated tens of millions of sharks a year, many of them from species now hurried onto CITES Appendix II — the oceanic whitetip and the hammerheads listed in 2013, and, in the sweeping decision of 2022 that took effect the following year, the whole of the requiem-shark and hammerhead families, bringing the great bulk of the international fin trade under legal control for the first time. A soup is not a sufficient reason to empty the sea of its oldest predators. And here the principle that governs this entire section can be stated without hedging, because it does not admit of a reasonable other side: novelty is never a sufficient reason to eat a threatened animal. The fact that a dish is rare, storied, expensive, or new to the eater's own experience adds precisely nothing to the ledger against a species' survival. Historical admiration is one thing, and this book has offered plenty of it; a modern plate is another, and the difference between them is the whole of the law and most of the conscience.

The Roll of the Vanishing

The shark is not alone at that frontier, and it is worth naming the company it keeps, because the curious palate meets these creatures precisely where its curiosity must turn back. Each is a delicacy somewhere; each is a species being eaten toward its end; and in each the same lesson recurs, that the rarer and more coveted a wild food becomes, the faster its price on the plate translates into a price on the population. The scale is easy to lose sight of: the IUCN Red List now ranks tens of thousands of species as threatened with extinction, and the roll lengthens with almost every assessment, so that the handful of creatures named below stand only as representatives of a list far longer than any single chapter could hold.

Begin with the animal that has quietly become the emblem of the whole problem: the pangolin, a shy, ant-eating creature of Africa and Asia, the only mammal on earth clad in scales and the survivor of a lineage some eighty million years old and, by every reckoning, the most trafficked wild mammal alive. Its flesh is prized as a luxury meat across parts of East and South-East Asia and its scales — which are nothing but keratin, the stuff of a fingernail — are ground into traditional medicine, and between the two demands something on the order of a million pangolins were stripped from the wild in the decade to the middle of the 2010s. The response was the strongest the system can make: in 2016 all eight species were raised to CITES Appendix I, closing international commercial trade entirely. That a creature most Western readers cannot picture should be hunted harder than any other mammal, for a soup and a folk remedy, is the single clearest measure of what an unchecked appetite for the rare can do.

The sea offers a case sharper still, in which a delicacy is erasing not only its own species but an innocent bystander. The totoaba, a large fish of the Gulf of California, carries a swim bladder that dries into what the Chinese luxury market calls fish maw, a supposed tonic that fetches thousands of dollars a kilogram and has earned the trade the nickname "aquatic cocaine." The totoaba is itself protected on CITES Appendix I; but the true catastrophe swims alongside it, for the illegal gillnets set for the totoaba also drown the vaquita — the smallest porpoise in the world, found in that one corner of sea and nowhere else — whose numbers have now fallen, on the most recent surveys, to fewer than ten individuals, perhaps only a handful. A luxury bladder for which the fish need not even be the target is dragging a separate creature, one no one is trying to eat, off the edge of the world. There is no clearer illustration of the principle that a food's cost is not always paid by the thing on the plate.

The toll is not always so exotic, nor always a single charismatic species. The frog's legs that France has prized since the Middle Ages now arrive, in their billions, from the wetlands of South-East Asia: between 2010 and 2019 the European Union alone imported the legs of as many as two billion frogs, France the largest consumer by a wide margin, and Indonesia — the chief supplier — is watching its big native species, the giant Javan frog and the crab-eating grass frog among them, thin out under a harvest that is almost wholly wild-caught and almost wholly unmonitored. The loss then runs outward in the way an ecologist learns to expect: fewer frogs mean more of the insects the frogs once ate, and so more pesticide sprayed on the rice paddies, and so a further turn of the same wheel. A plate of cuisses de grenouille looks a world away from a poached pangolin, but it sits on the same ledger, and the entry is written in the same ink.

Even a supermarket favourite can belong on this roll. The European eel, the unagi of a thousand Japanese counters, is listed by the IUCN as Critically Endangered — the number of young eels returning to Europe's rivers has fallen by more than ninety per cent since the 1980s — and has been placed on CITES Appendix II, and because the species has never been bred in captivity — every farmed eel begins as a wild-caught juvenile — the trade runs on the trafficking of transparent baby "glass eels" out of Europe on a scale that enforcement bodies have called one of the world's largest wildlife crimes, in defiance of an outright European export ban since 2010. And the songbird, which the Field Note below will follow to its bitter particular in the ortolan, is being eaten in numbers that beggar the imagination: BirdLife International's landmark survey The Killing, published in 2015, put the toll of birds illegally slaughtered around the Mediterranean each year at some twenty-five million, and Cyprus — where tiny warblers and blackcaps, trapped on limed sticks and in mist nets lured by electronic birdsong, are pickled or grilled into the forbidden dish called ambelopoulia and sold by the dozen in the back rooms of restaurants — sits among the very worst offenders, and the worst of all per head of population — though sustained enforcement in the British Sovereign Base Area on the island has since shown that determined policing can drive the killing sharply down. These are not exotic abstractions. They are eels on a conveyor belt and warblers on a lime-stick, and the curious eater's contribution to their survival is the same small, decisive act in every case: to know what he is looking at, and to leave it alone. The diner is the last link in that chain and, being the one who pays, the one best placed to break it — for a delicacy without buyers is a poaching economy with no reason to exist.

The Second Cost

Conservation is the first reason the curious palate stops at certain borders, but it is not the only one, and the second is easy to overlook because it falls not on the animal but on the eater and, through him, on everyone else. The wild meat trade of the tropical forests — bushmeat, in the shorthand of the conservation literature — carries a freight of disease. It is a huge commerce — on the order of millions of tonnes of wild meat are stripped from the Congo Basin alone each year — and to hunt and butcher a wild mammal is to open a direct channel between its bloodstream and one's own. The best evidence traces the origin of the human immunodeficiency virus itself to exactly such a crossing: HIV-1 descends from a simian immunodeficiency virus of chimpanzees that passed into people, most probably through the cuts and contact of hunting and dressing ape carcasses in Central Africa in the early twentieth century, a single spillover that has since cost the world tens of millions of lives. Several outbreaks of Ebola have been traced the same way, to contact with the bodies of infected apes and forest antelope; and the great forests of the Congo basin are meanwhile being hollowed out by the commercial trade into what ecologists call "empty forest syndrome" — woodland still standing, and green, and all but silent, its larger animals shot out along the logging roads that now reach into what was once too remote to plunder. And it is no accident that the coronavirus pandemic which closed the world in 2020 is widely thought to have emerged, in one way or another, from the human trade in wild animals; the appetite for the untamed creature and the emergence of the untamed disease travel, more often than we would wish, the same road. The lesson for this volume is narrow but firm: eating the rare and the wild is not only a debit against a species' survival but, sometimes, a wager with a new pandemic, and the frisson of the truly untamed animal is bought at a price that can be charged to strangers who never sat at the table.

Eating on the Right Side of the Ledger

It would be a poor ethics, and a false one, that left curiosity with nothing to do but abstain — and it need not, because the same open, adventurous palate this book has defended can be turned into one of conservation's more surprising allies. The trick is to point the appetite at the animal whose absence the living world would applaud. Consider the lionfish, a beautiful, venomous native of the Indo-Pacific that escaped into the western Atlantic in the late twentieth century and has since eaten its way through the reef fish of the Caribbean with no native predator to check it. Since 2010 the American ocean agency and reef conservationists have run frank campaigns under the banner of eating the enemy — training divers to spear it, publishing cookbooks, seeding restaurant menus — on the sound reasoning that a fish with a market is a fish with hunters, and that here, uniquely, every one eaten is a gift to the reef it was stripping. The same logic has been applied, with a marketer's cheek, to the invasive carp choking the rivers of the American Midwest and threatening the Great Lakes: in 2022 the state of Illinois formally rebranded the unloved fish as "Copi," a clean new name meant to move it from the problem column to the dinner plate. This is not a loophole in the chapter's rule but the very fulfilment of it. The Leopold sentence at the head of these pages asks only that an act tend toward the integrity and stability of the living community; an appetite that would empty a reef of grouper fails that test, and the identical appetite, aimed at the lionfish eating the grouper, passes it triumphantly. One honest caution belongs beside the enthusiasm — the so-called invasivore's dilemma: an animal with a market is an animal someone may come to wish to keep in supply, and a taste for the invader must never curdle into a reason to preserve it, so the tool is sound only where the aim stays fixed on eradication rather than on a steady harvest. Kept to that discipline, curiosity is not merely permitted here. It is doing good.

The Question of Suffering

Before the hard cases, the principle — and it was put most sharply not by a modern campaigner but by the founder of utilitarian philosophy. In 1789, in a famous footnote to his Introduction to the Principles of Morals and Legislation, Jeremy Bentham considered how the law ought to regard the beasts and swept aside every test but one: "The question is not, Can they reason? nor, Can they talk? but, Can they suffer?" Nearly two centuries later the philosopher Peter Singer built his 1975 Animal Liberation on that single foundation, giving wide currency to the psychologist Richard Ryder's word speciesism — the arbitrary discounting of an interest merely because the one who holds it wears the wrong kind of body — and arguing that the capacity to suffer is the one line that finally matters, the thing that earns a creature the right to have its pain weighed at all. One need not follow Singer to each of his conclusions, and this book does not, to accept the core of the point: where an animal can suffer, its suffering counts for something real, and that something is not cancelled by the fact that a human palate finds the result delicious.

Conservation asks about the species — whether an animal's kind can bear the loss. Welfare asks a different and narrower question, about the individual creature and the quality of its dying, and here this book must be more careful, because here thoughtful people of good faith genuinely part ways, and a chapter that pretended otherwise would be preaching rather than reasoning. Foie gras is the standing test case. The fattened liver is produced by gavage, the force-feeding of ducks and geese through a tube in the last weeks of life until the organ swells to as much as ten times its natural size. Its defenders — and they include serious cooks and some veterinarians — argue that waterfowl are built to gorge before migration, that they lack the gag reflex and possess the pliable oesophagus that make the feeding far less violent than it looks to a squeamish onlooker, and that a well-run farm's birds show few of the classic signs of distress. Its opponents answer that the swollen liver is by any medical definition a diseased one, that the confinement and the mortality rates tell their own story, and that a practice we would call an illness in any other animal cannot be laundered into a delicacy by the excellence of the result. Its production is already illegal in the United Kingdom and in a number of other countries. This book will not hand down a single verdict on foie gras, because the honest state of the argument is that reasonable people, looking at the same birds, still disagree — and saying so is itself part of the ethics.

The same honest uncertainty hangs over the fish on the slab. Whether a fish feels pain as we would recognise it is a question scientists genuinely contest — the biologist Victoria Braithwaite marshalled the evidence that fish possess pain receptors and alter their behaviour when hurt, in a 2010 book that asked the question in its very title, while other researchers hold that a fish's brain lacks the machinery that would turn injury into felt suffering — and the practical upshot is a spreading consensus that the humane course is to stun and kill an animal quickly rather than let it thrash out its death in the air. Here too the reasonable positions have not yet converged, and here too this book declines to pretend that they have.

But disagreement at the frontier does not mean there is no floor, and the clearest way to find the floor is to walk to the case where the ground gives way entirely. Consider the live octopus — swallowed still moving, or sliced while its arms yet coil on the plate, for the frisson of eating something visibly alive. What we have learned about the animal in question makes this the sharpest welfare question in the book. The octopus is not a reflex in a shell; it is, on the current weight of evidence, a genuinely sentient creature of startling intelligence, with a large and distributed nervous system and a repertoire of behaviour that the scientific community now reads as the marks of felt experience. In 2021 an independent review led by the London School of Economics found the evidence for sentience in cephalopod molluscs and decapod crustaceans strong enough to act on, and the Bill that became the United Kingdom's Animal Welfare (Sentience) Act 2022 was amended during its passage to recognise octopuses, along with lobsters and crabs, as sentient beings in law. That same widening circle of recognition had already reached the kitchen elsewhere: since 2018 it has been illegal in Switzerland to drop a live lobster into boiling water without first stunning it, and illegal to keep the animals on ice, the law resting on the plain finding that a crustacean can feel the pain we are inflicting. To eat an animal alive, for the spectacle of its struggle, is the case the floor was built for. Reasonable people may argue about the fair killing of a fish or the fattening of a goose; no honest account can defend inflicting distress on a demonstrably sentient animal because the distress is the entertainment. That is the test this chapter will not soften: cruelty practised for novelty fails it, whatever one concludes about the harder cases above. Suffering is not redeemed by being interesting.

The Forager's Conscience

There remains the wild larder, which feels innocent of all this — no farm, no abattoir, no one's animal, only the free gift of the hedge and the wood. It is not innocent, only quieter, and its harms take three forms the responsible forager learns to see. The first is overharvest. A wild plant can be loved to death, and the clearest recent example is the ramp, the wild leek Allium tricoccum, whose rise to fashion on the spring menus of celebrated restaurants has stripped whole woodlands; the plant is painfully slow, a colony spreading by less than a tenth each year, so that a single enthusiastic afternoon can undo a generation of growth. The Canadian province of Quebec has classed it a vulnerable species since 1995, capping a forager at fifty bulbs a year for personal use and forbidding its commercial sale altogether — which is why a Montréal restaurant, unlike a New York one, cannot legally put it on a plate. The second harm is trespass upon protected ground, where the cumulative arithmetic of many people each taking "just a handful" is exactly the arithmetic that empties a reserve; it is why the law in many places, England's Wildlife and Countryside Act among them, lets a forager pick the fruit and leaves of a wild plant for his own table but forbids him to uproot it, and why some fragile commons now ban the taking of wild fungi outright. And the third harm is the oldest and most personal: the wild table can kill the forager outright. The death cap, Amanita phalloides, is responsible for the great majority — on the order of ninety per cent — of the world's fatal mushroom poisonings, and it kills chiefly by resemblance, taken for an edible straw mushroom in one part of the world or a young Caesar's mushroom in another, odourless and, by the accounts of those who have survived it, pleasant-tasting; worse still, its poison works by ambush, the first symptoms holding off for six to twelve hours or longer — time enough for the victim to conclude the meal was harmless — before the amatoxins begin their silent destruction of the liver; and those toxins are heat-stable, so that no amount of cooking, boiling or drying makes it safe. The forager's first rule, therefore, is not a recipe but a refusal — never eat a wild thing on a probable identification — and the rules that follow are of a piece with the rest of this chapter: take little, take only what will regenerate, never from protected ground, and never, ever on a guess.

Field Note — The Ortolan

No single dish draws the line of this chapter as sharply as the ortolan, and none has been defended with such ceremony. The ortolan bunting, Emberiza hortulana, is a sparrow-sized songbird, netted on its autumn migration through the pine-shaded Landes of Gascony. In the old ritual the captured birds were kept in the dark — historically even blinded — so that, mistaking the constant night for the long dark of pre-migration, they gorged themselves until they doubled or trebled their weight. Fat, they were drowned alive in a glass of Armagnac, which killed and marinated them in a single act; roasted whole; and eaten whole in a mouthful or two, bones and hot fat and all, by a diner who traditionally draped a napkin or a towel over his own head — variously said to trap the escaping perfume, or, more tellingly, to hide the gluttony of the act from the eyes of God. It was reputedly among the last things François Mitterrand chose to eat, twice over, at his final New Year feast before his death in 1996: the dish of a connoisseur's connoisseur, wrapped in the manners of a penitent.

It is also, now, a crime. France banned the taking of ortolans in 1999, and the bird is protected across the European Union under the Birds Directive; yet the ban went largely unenforced for years, with tens of thousands of birds still killed each autumn, until pressure from conservationists drove the European Commission to refer France to the Court of Justice of the European Union in 2016. And the conservation reality is more damning than the global ledger first admits — which is exactly why the case is instructive. The IUCN lists the species as a whole as Least Concern, a label the defenders of the hunt have leaned on; but the European breeding population fell by an estimated eighty-eight per cent between 1980 and 2016, France's own by some thirty per cent in a single decade, and a 2019 study in Science Advances showed that the birds funnelled into the French nets are drawn disproportionately from small, fragmented, sharply declining northern populations, so that the harvest is not the sustainable skimming of an abundant species but a measurable push toward local extinction. Here, then, is the whole argument of the chapter compressed into two mouthfuls: a food of real ritual, real history and, by every account, real deliciousness, whose true price is a collapsing songbird — eaten under a napkin, so that no one, perhaps not even God, has to watch. It is the precise place where curiosity, to remain a virtue, has to say the word this chapter has been teaching it to say.

The Line

The commitment can now be set down in plain words, as the counterpart to the Authenticity Mandate that governed the volume before this one. Curiosity, yes; harm, no. The open palate this book has defended is free to cross every border that culture and squeamishness have drawn, and it is bound at the two borders that matter: it does not eat a species toward its end, and it does not buy its novelty with an animal's gratuitous suffering. Historical dishes that fail this test — the tortoise in the hold, the turtle in the tureen, the whale, the songbird under the napkin — keep their place in these pages as history, told honestly and set beside the conservation reality in the same breath, precisely so that the reader can savour the record without reaching for the plate. Novelty is never a sufficient reason. Rarity is never a sufficient reason. "It is traditional" is never a sufficient reason, for tradition is only a habit with a longer memory, and habits, as the last chapter showed, are the one thing an eater can be taught to change. The naturalist's licence to be curious is real, and this volume has spent itself defending it; but it is a licence, granted on terms, and the terms are written in Leopold's plain sentence at the head of this chapter — that a thing is right when it tends toward the integrity, stability and beauty of the living community, and wrong when it tends the other way.

With that line drawn, the reader can at last be trusted with the menus. The chapter that follows gathers the real and reconstructed bills of fare of this whole adventuring tradition — the Beagle's opportunistic table, the polar rations, the affectionately imagined Glutton Club dinner — and several of their dishes, read cold, would horrify or indict a modern cook. That is the point, and it is why the ethics had to come first. A reader who has built the wall by hand can walk through the museum of the daring palate without mistaking it for a shopping list: free to marvel at what the curious once dared, clear-eyed about what the curious may now do, and able, finally, to tell the difference between admiring a history and repeating it.
