Pollan's Progress

Michael Pollan is the prophet for the local food/real food movement, to the extent that there was a serious effort to have him named as Secretary of Agriculture in the Obama administration. He is probably the person most single-handedly responsible for shifting the perspective of a significant proportion of our nation regarding food and how it should be produced. If he did not coin it, he has clarified and explained the concept of "industrial agriculture". Reading his book, "The Omnivore's Dilemma" (2006), has been what many have described as the signal moment when they realized that they had to redefine their relationship to food, and how it is produced. He has certainly had a profound influence on my thinking.

I've become more and more interested with his progression to where he has arrived. I was intrigued by his statement on a recent TV interview that he had reached this place because of his experience as a gardener. If I recall correctly, he said that gardening had made him think about food and how it was produced. I've been reviewing his books and his personal evolution, as reflected through them. The books are remarkable in that they are both intimate and lofty. While he poses big, universal questions, he then muses aloud, relating his own personal experience (with sometimes embarrassingly self-revelatory snips, like reading The Selfish Gene while stoned on pot), and yet manages to place the subject within an extensively researched and broad historical context (most of his books have a comprehensive bibliography) .

Pollan is a journalist who wrote extensively for the New York Times Magazine before beginning with books. But he bought a piece of an old farm in Connecticut in 1983, began to garden, and then to write about it. This eventually led to his first book, "Second Nature", first published in 1992. The book made quite an impression on me when I read it shortly after its publication. It is a personal exploration of his own evolution as a gardener, with chapters on miscellaneous subjects like choosing a tree to plant (alas, it was a Norway maple), the politics of garden catalogs, his grandfather's garden and what he learned from it, lawns, weeds, and rose gardens. There are some amusing stories, some that are touching. But Pollan gives away his real identity as a seriously serious writer in the Introduction: "...I soon came to the realization that I would not learn to garden very well before I'd also learned about a few other things: about my proper place in nature...about the somewhat peculiar attitudes toward the land that an American is born with...about the troubled borders between nature and culture; and about the experience of place, (and) the moral implications of landscape design..." He then somewhat bashfully admits, "It may be my nature to complicate matters...to search for large meanings in small things...". Yup.

Probably the most significant chapter in the book is "The Idea of a Garden", in which he explores most of those questions from the Introduction. He tells a sad story of old-growth trees in a Nature Conservancy tract that were felled by a tornado. What to do? Remove the trees, which would make the forest pretty again, and less likely to be a fire hazard? Or let "nature" take its course by leaving them in place? The final decision in such cases is destined to meet some human desire (whether for a pretty scene or a sense of untouched wilderness). This leads to a musing on what the real "nature" of such a place really is, and what is the meaning of wilderness in the presence of humans. The overall conclusion is that we treat all of nature as a garden, even when we are trying to "preserve" or to "restore" it.

His next book (if we skip over a book about building a house) was The Botany of Desire (2002). Here again is the theme of the interaction of humans and nature. But a new insight is expressed here - that we are interacting with plants, influencing their evolution while they influence us. Pollan chooses just four plants to discuss, the tulip (a discussion of tulipomania and our fascination with flowers), the apple (Johnny Appleseed, wild and heritage apples), marijuana (humanity's need for intoxication), and the potato.

Particularly in this last chapter, we see the present Pollan emerging. He discusses the spread of the potato across Europe and the effects of the late blight epiphytotic in Ireland in the 1840s, while also traveling to Monsanto in St. Louis to learn about genetic engineering. Talk about going into the belly of the beast - just as he would later buy a steer and follow it all the way to the slaughterhouse, he obtains potatoes that contain the gene for Bt resistance and plants them in his own garden (he would later discard them rather than serve them to the unsuspecting). He later visits a potato farmer in Idaho, where he sees the many baths of pesticides that potatoes grown conventionally must be treated to. (A moment of hilarity ensues when he is served a potato salad made of freshly dug potatoes that include the genetically engineered variety as well as some presumably pesticide-treated ones.) Afterwards, he visits an organic potato farmer, whose complex adaptive strategies are described at length. And then for the first time, he uses the phrase "industrial agriculture", as he discusses the efficiencies of monoculture and the problems it creates. (Of which the Irish potato famine is again presented as a prime example.) After musing on our collective responsibility for demanding perfect McDonalds' french fries and thus perfectly industrially produced potatoes ("the problem of monoculture may be as much a problem of culture as it is of agriculture"), he goes home to harvest his own (untreated) Kennebecs.

So - the perfect circle, from the gardener to the front lines of the food system, and back to the garden again, where it all begins.

Green Mystery

Ah, spring, thou art come at last. I am in my garden, and the students are drinking green beer. Both of these are related to the celebration today of St. Patrick's Day. Who or what St. Patrick was is scarcely relevant to the fact that it gives us all a chance to wear or consume green. But it is also the day on which I aspire to be planting my first crop of the year. I didn't quite make it today because my vegetable garden is still a little too "mudlucious" (apologies to e.e. cummings). Since it was in the mid-60s today, I'll see tomorrow whether I can cultivate a row of soil and sow some lettuce seeds. Some years I have been able to do this on St. Paddy's day. I cover them with row cover and after the obligatory late March snow storm, I find little lettuce seedlings smiling up at me. It means we can enjoy early salads.

I think every human being must notice and rejoice in spring. But to a gardener it is truly like a universal rebirth. There is nothing to make the heart rejoice like the first flowers. I found snowdrops and winter aconites blooming under the shrubs on our east border just a few days ago. But what is even more notable is that our plants are preparing to do their work again to make possible human life and all animal life on this planet for another season. Pretty generous of them, all considered. Although I am thoroughly enchanted by the flowers, another important discovery was that the garlic I planted late last fall is sending up sprouts. The garden has begun.

As a botanist, I've studied details of the miracle of photosynthesis, by which plants convert the energy of sunlight into carbohydrate and thus food. Think about it— our entire global economy is based on it. It is the basis of our "growth strategy"—without a continual energy input, nothing we recognize would exist. And though this process varies in some qualities within organisms that practice it, it always requires chlorophyll, where the actual energy capture occurs. And that is green.

It is surely not an accident that many ancient religions made spring into a special event. And many of them celebrated the green. Most notable of these were perhaps the Druids. From my extensive reading of the literature— er, that's the English mystery novel literature—I know that the Green Man is still regarded as a mythical figure in some English recreations of rituals.

The "mystery religions", secret societies that celebrated the renewal of life, often through the rebirth of a dead god or emissary, have often been cited as the precursors of Christianity. Of course this has been controversial but many Christians, including Martin Luther King, have taken the trouble to rebut this concept. As one of these explained, "The annual vegetation cycle was often at the center of these cults. Deep significance was given to the concepts of growth, death, decay and rebirth." It might be noted that we of the Christian tradition celebrate Easter in the spring, with eggs a symbol of new life. Zorastrianism, another religion sometimes credited as a predecessor of Christianity, made the first day of spring as the beginning of the New Year. Persians (Iranians) still celebrate this festival, called Nowruz . Though they are mostly Moslem now, this ancient Zorastrian holiday (at the spring equinox) is very important in Iran, and is celebrated among other things by having a bowl of wheat, lentil or barley sprouts on the table, as well as an egg for everyone.

My own belief is that all of these rituals and celebrations indicate a deep understanding that those first green sprouts of spring mean that the universe will continue, the plants will bring it to life around us, and we will also persevere, by grace of the green. Lift a mug to it, if you will.

This Garden Earth


Thomas Princen's book, The Logic of Sufficiency, is not an easy read but contains plenty of food for thought about the socioeconomic principles by which we live and their effect on our planet and ourselves. (Yes, I'll get back to the garden at the end.) He points to the ascendance through the last century of the concept of "efficiency", which is used here as a catchall phrase for many terms and practices that characterize the "market" approach (my summary, not his).

He contrasts this with what he calls "sufficiency"; "the sense that, as one does more and more of an activity, there can be enough and there can be too much." I love the illustration on the cover - the glass not half full or half empty, but full. And yet it is not running over.

The point is that "efficiency" is aimed at increasing yield or wealth for individuals or groups, which leads to more and more exploitation of resources, whether they are soil, water, trees, human effort, or the ability of the planet to absorb insults like pollution and global warming. But our planet is near its "biophysical" limits (see also "Spaceship Earth") and we need to adopt approaches that are sustainable on a system-wide level.

This is beginning to sound like an environmental text, but it is not, though he does refer to environmental concerns and endorses "ecological rationality". It is really more of an essay on economics and how assumptions and beliefs about economic mechanics have brought us to where we are, at the brink of a catastrophic tumble (again, my words, not his). One of the frustrating things about reading the book is that he teaches by long example, such as the story of Pacific Lumber (long-term management of old-growth redwoods) and a lobster fishery (deliberate restraints on fishing to maintain stocks). There is no list of bullet points for a quick take-home message; it requires really studying all the examples and what they mean about behavior that incorporates frugality, moderation, a sense of limits, and allowing respite (his term) for people, animals, and natural systems. (Note that "resources" is actually an efficiency-type term.) A great windup is where he shows that "efficiency" is to blame for mad-cow disease. He also mentions (in a book published in 2005) that we have been turned into "consumers" and driven into debt in order to support a society built on efficiency.

Since Princen doesn't supply sound-bites for his thesis, I won't try to either. It does have strong echoes of Garrett Hardin's Tragedy of the Commons. I heard Hardin speak in the 1970s and his favorite story was about the common pasture where 10 cattle could graze without harming the capacity of the pasture to renew itself. If 10 farmers graze 10 cattle, all goes well. But one of them decides that he wants more, so puts an additional animal onto the commons. It suffers just a little but then the others see that someone is getting more than they are, so they put additional cattle on too. Soon the pasture system collapses and can't maintain any cattle at all. That is where the market ideology (aka efficiency) has nearly brought us today.

Yes, I'm postulating that our entire planet is like that pasture - or like a garden. If we can learn to take only from it what is sufficient, while we continually build up the soil and understand the complexity of the plants, animals, and physical environment that make it up, our garden can support us for a long time. We should cultivate it wisely.

Contrariwise

Since I've been predicting disaster for years, I particularly enjoyed an article in the January 26, 2009 New Yorker discussing "The Dystopians". It describes the people who have made it their career or at least their avocation to tell the rest of us about how bad things are going to get. An outstanding example is the author James Howard Kunstler, who has written such books as The Long Emergency. I only discovered him with this article. Another author mentioned is Nassim Nicholas Taleb, who wrote The Black Swan. That one I read last winter, before our economic system collapsed enough that everyone noticed. As the author of the article (Ben McGrath) notes, these days are great for celebration of "triumphant pessimism".

Now Taleb is getting a major following from newly converted financial professionals. His writing is very hard to follow; he alludes to chaos theory and various statistical models without really explaining any of them. The basic idea is that we fall in love with the current trend and situation and expect that things will go on forever as they are, only maybe getting better and better. His clearest exposition of this is with the story of the turkey who enjoys day after day of plentiful food, water, and sunshine. The turkey confidently predicts that this will go on forever, and his predictions are good - until Thanksgiving Day. This was exactly like our county's budget director who every year presented a budget with ever-increasing totals and the comment, "The best prediction of the future is the past." Now the county has a $10 million deficit and is closing entire departments. Unfortunately, my protests at the time had little effect, and someone once informed me that I was a "contrarian". "I told you so" after the fact is pointless and unsatisfying.

McGrath reveals a taxonomy of sorts of pessimists - "peak oilers", "back-to-the-land types", and generalized Cassandras, "doomers". My husband has been a "peak oiler" for decades and the Hubbert Peak was one of the themes of our household discussions. More recently we've both read lots of Jared Diamond. His book, "Collapse" gives a detailed backward look at how many societies have failed, and there are many uncomfortable parallels to be found with our own. There seems to be a fatal human tendency to ignore the long-term consequences of our actions. Since I see the universe in terms of thermodynamics, I have always had trouble with people who persist in believing in the free lunch.

My particular place in the taxonomy of "doomers" is the back-to-the-land type. I've been looking with horror for some years at our drawn-out food chain - how can we possibly be expecting a stable food supply from a distance of thousands of miles? Just as Voltaire cultivated his garden during the dying decades of the French monarchy, I am seeking to find a self-sustaining life to the extent possible. Thus the support for local enterprise, local farming, and thus I grow and preserve as much of our own food as I can. Food security is the most basic human need and it is not a given. We should be worried. I am. More on that later.

Part of being self-sustaining is learning a new way of eating and cooking. I've been learning new ways to use my bountiful sauerkraut production. Here is a new recipe I just discovered. It is modified from one I found among my mother's files.

Winter Slaw with Apples and Sauerkraut

1 quart sauerkraut, preferably raw (drain, place on a board, and cut up into smaller pieces)
1 apple, peeled and chopped
2 celery stalks, chopped
1 small or 1/2 large sweet onion (Walla Walla type), chopped
1/2 sweet red pepper, chopped (I used frozen, roasted and peeled red pepper)
1 T seasoned Japanese rice vinegar (contains sugar and salt)
1 t sugar

Marinate the onion briefly in the vinegar, then add the other chopped ingredients, then the sauerkraut. Mix and chill for a little while before serving.

Note: no salt needed - the kraut is slightly salty, as is the vinegar.
Adjust sugar and vinegar to taste.

This has a nice fresh flavor and is a very light dish.

The Ethics of Eating (a fish tale)

One pleasure of having a vegetable garden is that it embodies sustainability. It is sad that this good word is overused today, but it still speaks to a good concept and ethos. The classic expression was voiced by the UN Brundtland Commission , defining sustainable development that "meets the needs of the present without compromising the ability of future generations to meet their own needs". It implies good resource management and renewal. With a vegetable garden, nothing is wasted; you draw vegetables and life from the good earth, and every stem, stalk, leaf and giant squash that isn’t used goes back to compost to begin again the next year. This has the satisfaction of an ethical act.

The ethics of sustainability are more difficult to achieve with purchased food. If you are a conscientious person, eating most foods requires a considerable amount of selective forgetting. Every bite completes a long chain of events, many of them with ethical coloration. Since it is unpleasant to ingest sins and indiscretions with one’s food, the natural thing is to overlook them. But when we see ourselves as part of the greater scheme of things, it is possible and good to stop sometimes and look that forkful in the eye (or whatever part has been impaled). Here are some ethical questions to consider over dinner.

1. Has the food required the sacrifice of another animal’s life?
2. Was the individual food animal treated humanely before death and was it killed humanely?
3. If the food required restraint of an animal (as, for example, with eggs and milk), was that humanely managed?
4. If harvesting a wild animal was involved, did the process endanger the survival of the species? Were only the animals to be eaten killed?
5. Were whole ecosystems damaged in order to grow a particular food crop?
6. Were people enslaved, maltreated, deprived of their own food choices, or subjected to bad governance in order to grow or process the crop?
7. Is the crop practice appropriate to the whole ecosystem, or does it cause erosion, overfertilization of water sources, greenhouse gas emission, accumulation of toxic chemicals in wildlife and humans, loss of gene plasm diversity in the crop species, air or water pollution?
8. Is the energy cost of processing and transporting the food excessive for the little food value contained in it?

We who seek sustainability are making more and more ethical choices about food. It may restrict the variety of things we can eat or be more expensive but at some point the food looks back at you from the fork and you have to make that next step. We gave up veal a couple of decades ago and never even consider fois gras. Lately we’ve been seeking out meat from grass-fed animals and buying “Amish” poultry because they are reputed to be better treated. We try to buy as much food that is produced locally as is feasible (if it is organic, even better) and look carefully at the selection of fair trade coffee and chocolate. In the process, we change our taste for food so that the unethical choices don’t even look appealing any more.

Michael Pollan certainly laid out a lot of this for us in The Omnivore's Dilemma. Reading that was a life-changing experience for many. Now Mark Bittman, writing in the New York Times, hits us with the bad news about fish.

Here is the short version: Worldwide, we have almost depleted the populations of the most desirable wild fish. In 2003, 32% of populations had crashed, 39% were overfished, and the remaining 29% were "fully exploited", at the limits of sustainability. Even more troubling, industrial fish farming is threatening the stocks of the smaller fish that are the food of the larger ones like salmon and tuna. Huge quantities are being ground up to feed to farmed salmon. Salmon and shrimp farms cause immense water pollution (a farm of 200,000 salmon produces as much fecal matter as 60,000 humans) and despite heavy use of antibiotics, pose a disease threat to wild populations. Bittman proposes that we should avoid farmed fish (though tilapia can be farmed sustainably, he dismisses it as tasteless, which has been my experience) and eat the smaller ones, like sardines and anchovy.

I've been eating more canned sardines and use canned wild salmon, but what about fresh fish? One option is to eat more locally - freshwater fish native to this continent. I love walleye though it is expensive and somewhat seasonal. But in following Bittman's "small fish" lead, I remembered smelt.



The Rainbow Smelt (Osmerus mordax) is not native, but has been established in the upper Midwest freshwater lakes, originally seeded as food for salmon. They are still caught by locals during "smelt runs", typically in March-April. But they are available and cheap (the pound I bought cost $3.49) in the freezer as headless and dressed individually frozen fish.


These little babies are eaten whole and can be panfried or baked. But deep-fried smelt are popular in many Asian cuisines and lakeside fish restaurants. And the bones are good for you. As you crunch, think sustainability. Have your friends over - one pound will feed 4, or 6 with the fried vegetable sides and a salad. There are many possibilities for the breading (including the classic flour-egg/milk-bread crumbs or cornmeal), but I think a very light tempura batter is nicer.




Deep-fried Smelt

Tempura batter: combine 1 egg yolk with 2 cups of ice-cold water and 1/4 t baking soda. Stir in 1 2/3 cups of flour. This should produce a thin batter that is a little frothy.

Drop dressed, thawed and drained smelt into flour (may be seasoned) on a plate, shake off the excess, then quickly drop one at a time into the batter, retrieve with tongs (edit: on trying this again, I found that using one's hands are the easiest and most effective way to take the fish from the batter, though messy), then drop into hot oil. Oil should be deep enough to submerge the fish completely. Do not try to cook more than 3 or 4 (edit: or about 6) at once. Remove with a slotted ladle or frying strainer or tongs after each is light brown (2-4 minutes). Place in pan in a 200° oven while finishing the batch. Serve immediately with any preferred sauce, from mayonnaise-based tartar sauce to Asian soy sauce-based, or just offer lemons to squeeze. Note that this recipe has not included salt unless it was added with the flour. (Edit: a tomatillo/green chile/cilantro salsa or Indian chile/cilantro green sauce are excellent with this and the vegetables. Think pakora.)

Great additions: sweet potato rounds, half mushrooms, cauliflower buds, onion rings, or any vegetable that is not too wet and can stand up to this treatment. Or - make potato (French) fries - the batter makes them wonderful. Dip them in the batter without the preliminary flouring and fry separately from the fish. Remember not to crowd - if the temperature of the oil drops, they'll be oily.

Notes on deep-frying: the secret of delicious fried food, crisp on the outside, moist inside and not oily, lies in using the correct oil temperature. This is usually stated as 325-375° but keeping to the higher temperature is better. Use a kitchen thermometer. You should use only oils that can stand up to the heat. This is dependent on their smoke points - no oil with a smoke point under 400° should be used. I prefer peanut oil because it has a neutral flavor; I find that canola oil develops an unpleasant odor when heated to a high temperature.

There is real danger in heating oil on the stove - you can be severely burned from splashes and it should never be left unattended or allowed to heat to the oil's smoke point. One way to avoid trouble is to use a cast-iron Dutch oven for deep-frying. The steep sides prevent splashing. Don't fill any fuller than necessary. I usually use about a quart of oil in my 7 qt pan. Oil can be reused once if filtered and stored in the refrigerator.

May You Live in Interesting Times

We have certainly arrived in that moment. Although today is a day of hope for new beginnings, it is also surely not the end of a run of really bad news and there is a mountain of uncertainty ahead. Humanity has just about succeeded in ruining the planetary weather systems, kills off an increasing number of other species every year, and it seems that every other week natural disasters like tsunamis and earthquakes claim more human lives. In addition, new plagues (whether AIDS, avian flu, or foodborne toxic E. coli) continue to pose a threat, civil wars in many parts of the globe seem to trend toward genocide in their cruelty and viciousness, food scarcity is increasing, and government regulation has proved ineffective against adulteration of imported foods and drugs. In this country as well as others, civil liberty and freedom of thought have been damaged with the apparent complicity of a good half of the population. On top of all that, the world economic system has been destabilized. What to do? Voltaire had the answer. "Il faut cultiver notre jardin." Or, as usually translated, "We must cultivate our garden."

Voltaire's garden has virtually become a kōan for Western writers. Everyone has an interpretation of what Voltaire meant by this innocent-sounding conclusion to Candide. Surely one of the most leaden ones is that of a recent translator, Burton Raffel. In a rejoinder to a review of his translation, he asserts that "Candide is a novel, not a philosophical tract" and vigorously defends his translation of the phrase as "we need to work our fields", arguing that the verb cultiver meant in Voltaire's time "to bestow labor upon land in order to raise crops".

But as Adam Gopnik argues in a beautiful review of the book Voltaire in Exile, "By 'garden' Voltaire meant a garden, not a field—not the land and task to which we are chained by nature but the better place we build by love. The force of that last great injunction,'We must cultivate our garden', is that our responsibility is local, and concentrated on immediate action." Gopnik also notes that though the conclusion of Candide "seems to retreat from a confrontation with human cruelty to an enclosed garden, its publication marked Voltaire’s... moral development ... toward a faith in liberal meliorism."

Voltaire lived through "interesting times" too. He was born François-Marie Arouet in 1694 in a France where the excesses of the aristocracy and monarchy were already laying the foundation for the French revolution that began nearly a century later (1789). He made his way into the outer circles of high society as a poet and playwright (and assumed the name of Voltaire), was exiled to England for a time because of his impertinence, made money by what appears to be a bit of a scam involving a public lottery, wrote a number of very serious treatises, some of which were iconoclastic, was eventually exiled from France and settled near Geneva. He was appalled by the suffering caused by the Lisbon earthquake of 1755, by the cruelty of the Spanish inquisition, by the destruction caused by the Seven Years' War, by the pitiful condition of the peasants. His disgust at the torture and capital punishment used in France and elsewhere (in which living bodies were rended asunder), especially on religious grounds, led to his campaign against l'infâme.

So what did he do? He made a garden. In exile near Geneva, he developed estates, first at the leased villa Les Délices, then at one he purchased at Ferney. He really did garden, writing the friend who owned Les Délices, "Many thanks for the lavender; I promise to have it planted in all the borders of your kitchen garden...at this moment I am sowing your Egyptian onions...Please send me everything you can in the way of flowers and vegetables."

But Voltaire's garden wasn't just about producing food or having pretty views, though it certainly did that. He created a productive enterprise to benefit his little corner of the world. When he first took possession at Ferney, he wrote to a friend that the landed estate was depopulated and miserable, without industry or resources. "My land is excellent, and yet I have found (50 hectares) belonging to my inhabitants which remain uncultivated...it is seven years since the curé celebrated any marriages, and no children have been born...poor people who have scarcely even any black bread to eat, are arrested every day, stripped, and imprisoned, for having put on this bread a bit of salt which they have bought (without paying taxes)...One's heart is torn when one witnesses so much misery. I only bought the Ferney estate in order to do a bit of good." He immediately put workers to cleaning and widening ditches, plowing fields, and planting vines. He visited his cowsheds: "I love my bulls...I stroke them and they make eyes at me". He bought and bragged about new farm implements. Over time he brought in more people and became the patriarch of a little community. He even initiated an industry to support his people, a watch factory which, with his astuteness in merchandising, became a successful business. (Quotes and information from Voltaire In Exile, by Ian Davidson.)

So, the point - the meaning of Voltaire's garden is not a retreat but an engagement. In times like these, we must make our little corner of the world into a generative force. This includes the support for local farming operations, community gardens, the ability to keep chickens, local commercial enterprises, growing and preparing our own food and in general the betterment of our small community to enhance our sufficiency. This is where reality truly lies and where goodness begins. Now I must go cultivate my garden.

Quantum Broccoflower


For some time now, I've been fascinated by the importance of fractals in nature. These are mathematical relationships that create a certain type of geometry best characterized as "self-similar". I'll let the mathematicians explain. See http://classes.yale.edu/Fractals/ . Fractals are closely related to the Fibonacci sequence, in which each number is the sum of the two preceding numbers, thus 1, 1, 2, 3, 5, 8 and so on. You are saying Why is this in a blog about gardening and food??. Because plants grow according to this mathematical sequence and are themselves fractal in form. The distances between nodes at the growth apex follow the Fibonacci sequence. As shown in this picture of Romanesco broccoflower (a cross between broccoli and cauliflower) , there is a lot of self-similarity to be seen.

But I was surprised to find this picture on the cover of Science illustrating a special issue on quantum matter. The explanation:

"Like a cauliflower, the quantum critical regime has the same appearance irrespective of viewing distance."

See, fractals really do describe the universe and everything.

And now to the garden

Probably Voltaire's best-known quote is from Candide where he concludes "we must cultivate our garden". You remember, Candide is an innocent who begins in a castle, where he studies under Professor Pangloss ("the best of all possible worlds") and falls in love with the beautiful Cunegonde, daughter of the baron. Through a series of misfortunes, he travels the world with Pangloss, (who becomes syphilitic and deformed), and recovers Cunegonde (who was raped and stabbed by invaders, enslaved, prostituted, and ultimately loses her beauty) ; meanwhile Candide is tortured, partially flayed, and almost eaten. Eventually he becomes rich (but loses most of it) and he, Pangloss and Cunegonde, together with a couple of companions, end up on a small farm in Turkey. Pangloss once again philosophizes that all has been for the best. Candide says "That's well said, but we must cultivate our garden". It should be noted that Cunegonde has in the meantime become an excellent pastry cook.

There has been much analysis of what Voltaire actually meant to say by the retreat to the garden. Some may be repeated here in subsequent posts. But for me it has meaning on both the real and metaphysical levels; gardening as a focus on the here and now, the garden as an escape from the cruelty of the world, but also the garden as a symbol of renewal and a metaphor of life. And it produces food, too.

So this blog will also celebrate a retreat to the garden, figuratively and literally. Here will be a record of my garden, musings about the universe — and food.
