Science and beer go together like philosophy and beer. Or art and beer. Or pretzels and beer.
Around the time of the American Revolution, brewing played an important role in the early study of chemistry. Dr. Joseph Priestley was one of the first people to isolate oxygen and identify some of its remarkable properties. He wrote a six-volume work entitled Experiments and Observations on Different Kinds of Air in which he describes a number of different “airs” – “gasses” in modern English – and his experiments with them.
His “fixed air” – our “carbon dioxide” – was readily supplied by a nearby brewery. The fermenting beer provided such a great and steady supply of the gas that it became a favorite subject for experimentation. Dr. Priestley found that in fixed air, “a candle would not burn, and a mouse would have died presently.” He even used an upside-down beer glass for his make-shift gas chamber:
If I want to try whether an animal will live in any kind of air, I first put the air into a small vessel, just large enough to give it room to stretch itself; and as I generally make use of mice for this purpose, I have found it very convenient to use the hollow part of a tall beer-glass… which contains between two and three ounce measures of air. In this vessel a mouse will live twenty minutes or half an hour.
For the purpose of these experiments, it is most convenient to catch the mice in small wire traps, out of which it is easy to take them, and, holding them by the back of the neck, to pass them through the water into the vessel which contains the air. If I expect that the mouse will live a considerable time, I take care to put into the vessel something on which it may conveniently sit, out of reach of the water. If the air be good, the mouse will soon be perfectly at ease, having suffered nothing by its passing through the water. If the air be supposed to be noxious, it will be proper (if the operator be desirous of preserving the mice for further use) to keep hold of their tails, that they may be withdrawn as soon as they begin to show signs of uneasiness; but if the air be throughly noxious, and the mouse happens to get a full inspiration, it will be impossible to do this before it be absolutely irrecoverable.
If that description made you feel bad for the mice, you should know that you are not the first to have that reaction. At least part of the time he was making these experiments, Dr. Priestly was a tutor at the Warrington Academy. A colleague of his at Warrington had a daughter named Anna Laetitia Aikin, later Anna Laetitia Barbauld, who grew up to be a prominent woman of letters. One of her early works was a poem, dedicated to Dr. Priestley, called The Mouse’s Petition. The poem was written from the point of view of a mouse that had been trapped by Dr. Priestley and lamented it’s prospective demise on the alter of scientific research. As the story goes, Anna placed the poem in the trap with the mouse, and when Dr. Priestley found it in the morning, he set the mouse free. Scientists, after all, are not completely heartless.
Beer of the week: Rusty Red Ale – Building on the work of Dr. Priestley, Antoine Lavoisier demonstrated that respiration and combustion are forms of oxidization: oxygen bonding with other elements. Like respiration and combustion, rust forming on iron is a form of oxidization. This red ale is from Wisconsin’s O’so Brewing Company. It pours a dark red-brown with a head that dissipates very quickly. The aroma is mostly of roasted malt. The beer is bready, and the flavor follows. It is pleasant and malty, but I’d like a little more flavor. Even more caramel malt or more hops bitterness. Or both.
Reading of the week: The Mouse’s Petition by Anna Laetitia Barbauld – Barbauld’s narrator mouse makes compelling appeals that are both philosophical and sentimental. The poem also has a line that makes me curious about how intimate the author was with Dr. Priestley’s work. The mouse claims that “The cheerful light, the vital air, / Are blessings widely given.” The term “vital air” was one of the names given to oxygen, so it is possible that Barbauld was making a specific reference to Dr. Priestley’s experiments with different gasses. Also, lest the reader get the wrong idea about the good doctor, Barbauld added a note to this edition of the poem to say that she did not mean to attribute any cruelty to Dr. Priestley, of whom she maintained the highest regard.
Question for the week: The use of animals in scientific research is a touchy subject. Some extremely important discoveries have resulted from the death and suffering of countless animals. Is there anything like a clear line that can be drawn between acceptable and unacceptable animal testing? For example, might we agree that testing cosmetics on animals is never ok, or that testing prosthetics on animals is always ok?
In my experience, people tend toward one of two extremes when analyzing the writings of the ancients (and, to varying degrees, those of other bygone eras.) The one extreme is to assume that the authors, as products of a primitive time, have nothing to offer. We are so much more enlightened now; all of the ancients must be regarded as quite ignorant. The other extreme is to ignore the faults of the ancients, or, if they cannot be ignored, to make every possible contortion to explain them away. The ancients could not err when it came to thinking because, as Homer’s heroes could single-handedly lift boulders that a dozen modern men could hardly budge, the philosophers of old possessed intellectual powers far beyond those of any modern genius.
Take, for example, the treatment of women by Aristotle and Plato. Our modern understanding of the differences between men and women is very much at odds with the apparent opinions of Aristotle and Socrates on the subject. What do we do in the face of these problematic ancient texts?
One approach is to throw out Aristotle and Plato entirely. Sexism is so embedded in their thought, some opine, that their writing can have no value in our modern world. Even as early as the 15th century, William Caxton wrote that “if [Plato] had made fault in writing of women, he ought not, ne should not, be believed in his other dictes and sayings.”* (As we will see shortly, Caxton does not actually find fault with Plato’s treatment of women.) Likewise, Aristotle was extremely wrong about the role of the female in sexual reproduction, so his philosophy on humans generally can’t be trusted. These “dead white men” are so out of touch with our modern knowledge and sensibilities that they can hardly be considered authoritative on any philosophical question.
(I pause to note that the bland dismissal of these thinkers as “dead white men” always amuses me. The ad hominem attack itself adopts the language of racism, implying that the value of the authors is somehow related to their skin color. At the same time, it ignores the fact that classifying Aristotle and Plato as “white” should certainly raise a few eyebrows.)
On the other side, there are those who would wave away the apparent sexism of the ancients. The easiest way to do that is to simply call them a product of their times and move on. But some offer more convoluted explanations in an effort to keep the ancients from ever being “wrong”. Caxton wrote, “I cannot think that so true a man and so noble a philosopher as [Plato] was should write otherwise than truth.” And because Plato must have been right, Caxton was forced to come up with a way to reconcile the apparently sexist writings of Plato with the more enlightened views of his own day. He did so by concluding that if Plato ever said anything derogatory about women, he was only speaking of Greek women. “For I wot well, of whatsoever condition women be in Greece, the women of [England] be right good, wise, pleasant, humble, discreet, sober, chaste, obedient to their husbands, true, secret, steadfast, ever busy, and never idle, attemperate in speaking, and virtuous in all their works—or at least should be so.” So if Plato says, for example, that teaching a woman to write is multiplying evil upon evil, that may true of ancient Greek women, not of modern English women.
A more modern defense of that same type is to find esoteric meanings that are different from the ancients’ explicit meanings. So when Aristotle, in Book I of his Politics, says that “silence is a woman’s ornament,” he actually means nothing of the sort. The line is actually a quotation from Sophocles’s play Ajax. In the play, Ajax has gone insane by the time he utters the line. Obviously, Aristotle would have been familiar both with the play and the context of the quotation. So when Aristotle says “silence is a woman’s ornament,” he is slyly hinting that only a mad man would actually believe what he is saying. See? Aristotle was never sexist in the first place!
As usual, I favor the course of moderation. We should neither discard the ancients (or any author, really) out of hand, nor should we engage in mental gymnastics to defend the position that any author is always right. There is untold value in studying our intellectual predecessors, but nothing is gained by accepting their writings uncritically.
Beer of the week: Furious IPA – This aggressively-hopped ale from Minnesota’s Surly Brewing Company pours with a nice fluffy head. The piney hops certainly dominate, but there is a good balance with caramel malt notes. The label says that this beer defies categorization, but the IPA label seems right to me.
Reading of the week: Hymn To Aphrodite by Sappho – Here’s a crazy idea: if you want to know the ancients’ views on women, how about reading the poetry of an ancient woman? This is the only complete poem that has survived from Greece’s greatest poetess.
Question for the week: Is there any extant writing older than, say, 1,000 years that is actually not worth studying? Is it possible that anything has survived that long without some serious merit?
*Caxton actually discusses the sayings of Socrates as if Socrates himself was the author of the Socratic dialogues. I have substituted Plato into the quotations to give Caxton the benefit of the doubt; surely he meant to discuss what Socrates said and what Plato wrote.
This is the thirty-seventh in a series on The Harvard Classics; the rest of the posts are available here. Volume XXXVII: Locke, Berkeley, Hume
It is shockingly easy to forget just how amazing our surroundings are. Every so often, one needs to be reminded to look on the natural world with awe. Consider this your periodic reminder, care of George Berkeley:
“Look! are not the fields covered with a delightful verdure? Is there not something in the woods and groves, in the rivers and clear springs, that soothes, that delights, that transports the soul? At the prospect of the wide and deep ocean, or some huge mountain whose top is lost in the clouds, or of an old gloomy forest, are not our minds filled with a pleasing horror? Even in rocks and deserts is there not an agreeable wildness? How sincere a pleasure is it to behold the natural beauties of the earth! To preserve and renew our relish for them, is not the veil of night alternately drawn over her face, and doth she not change her dress with the seasons? How aptly are the elements disposed! What variety and use in the meanest productions of nature! What delicacy, what beauty, what contrivance, in animal and vegetable bodies! How exquisitely are all things suited, as well to their particular ends, as to constitute opposite parts of the whole!”
So go outside with a beer and gaze in wonder at how the trees have changed from just a few weeks ago, how the clouds undulate in the sky like foam on a freshly poured beer, or how a stream’s flow is both constant and ever-changing.
Beer of the week: Avalanche Amber Ale – An avalanche is a terrifying and devastating event, but it also has something of a Berkeley’s “pleasing horror.” Avalanche Amber Ale is not terrifying, but it is terrific. It pours with a fluffy tan head atop a dark amber beer. On the nose are bread and caramel. This ale has a surprisingly light mouthfeel and just enough hops to balance out the plentiful malt. Breckenridge seems to know what they are doing.
Reading of the week: Three Dialogues Between Hylas and Philonous by George Berkeley – This short excerpt from the Second Dialogue comes at the end of Philonous’ argument that matter does not exist except in the perception. Just as Hylas has been wrangled into accepting the position that material has no existence independent of humans, Philonous pulls the rug out from under him and declares that material does exist because it is constantly perceived by God.
Question for the week: Where do you look for natural beauty?
This is the thirtieth in a series on The Harvard Classics; the rest of the posts are available here. Volume XXX: Scientific Papers
In 1911, a mere two years after the Harvard Classics was first published, Douglas Mawson (later Sir Douglas Mawson) led an expedition to map the coastline of Antarctica. He was an adventurer and a hero, but he was a man of science first. The great proof of this is not only in his scientific achievements, but also in his very attitude toward his objectives.
In 1912, Mawson was part of a brutal race against time and weather to get back to the base camp. He was part of a three-man surveying party that had pushed over 300 miles into (quite literally) uncharted territory. Suddenly, one of the dogsleds disappeared into a crevasse. With it went one of the men, B. E. S. Ninnis, the better half of the dogs, and most of the rations. Mawson and his remaining companion, Xavier Mertz, with little food (and no dog food) turn back to camp faced with the very real possibility that the weather and lack of supplies would thwart their attempted return.
Frostbite was a problem for them. But even worse was a condition called hypervitaminosis A. When humans consume too much vitamin A, they can suffer from adverse mental effects, hair and skin loss, and a slew of other nasty effects. And it just so happens that husky livers are chock-full of vitamin A. Of course, Mawson and Mertz did not know that; vitamin A was not even named until 1920. So when it came time to eat the sled dogs, they ate them liver and all. The results were deadly.
After nearly a month of trudging, eating stringy dog meat, and deteriorating health, Mertz succumbed. With the wind howling outside of the tent, his team members dead, and his own collection of physical ailments, Mawson considered just staying in his sleeping bag. It would be easy to just stay in the bag forever. But instead, he remembered this poem by Robert W. Service:
When you’re lost in the Wild, and you’re scared as a child,
And Death looks you bang in the eye,
And you’re sore as a boil, it’s according to Hoyle
To cock your revolver and… die.
But the Code of a Man says: “Fight all you can,”
And self-dissolution is barred.
In hunger and woe, oh, it’s easy to blow…
It’s the hell-served-for-breakfast that’s hard.
“You’re sick of the game!” Well, now, that’s a shame.
You’re young and you’re brave and you’re bright.
“You’ve had a raw deal!” I know — but don’t squeal,
Buck up, do your damnedest, and fight.
It’s the plugging away that will win you the day,
So don’t be a piker, old pard!
Just draw on your grit; it’s so easy to quit:
It’s the keeping-your-chin-up that’s hard.
It’s easy to cry that you’re beaten — and die;
It’s easy to crawfish and crawl;
But to fight and to fight when hope’s out of sight —
Why, that’s the best game of them all!
And though you come out of each gruelling bout,
All broken and beaten and scarred,
Just have one more try — it’s dead easy to die,
It’s the keeping-on-living that’s hard.
(Service, by the way, is known as the Bard of the Yukon. How appropriate for someone struggling for life near the South Pole to get strength from a poet of the far north.)
And those words inspired Mawson to break camp and trudge on. The day he buried Mertz in the snow, Mawson wrote in his journal: “I read the Burial Service over Xavier this afternoon. As there is little chance of my reaching human aid alive. I greatly regret inability at the moment to set out the detail of coastline met with for three hundred miles travelled and observations of glacier and ice-formations, etc.; the most of which latter are, of course, committed to my head.” See what I mean about Mawson’s attitude toward his geographic work?
Over the next thirty days, Mawson made his way back toward base. At one point, he fell through the ice. However the sled, what was left of it, wedged in the opening of the crevasse, and Mawson dangled from a rope above the abyss. Despite his weakened state, he hauled himself up, only for the edge to break away beneath him and leave him hanging once more at the end of the rope. He summoned all of his strength for one final attempt and dragged himself from the gulf in the ice.
Eventually, Mawson made it back to base camp. He returned without his companions, without his dogs, and without much of his skin and hair. What he did bring back was a great deal of geographical information, including names for two large glaciers on the Antarctic coast: Ninnis Glacier and Mertz Glacier.
Beer of the week: Alaskan Amber – Alaska has many nicknames, including “The Last Frontier”. But Mawson’s account of Antarctica makes Alaska seem relatively tame. And at least Alaska has breweries. From Juneau comes this delightful amber ale. It pours a clear dark amber with a good head. It smells mostly of roasted malt. The beer is smooth and malty, with hints of marshmallow and apricot. Delicious.
Reading of the week: Geographical Evolution by Sir Archibald Geikie – At the beginning of this essay, Geikie writes, “From the geographical point of view… we must rank an explorer according to his success in widening our knowledge and enlarging our views regarding the aspects of nature.” In this respect, Mawson ranks very highly among the great Antarctic explorers.
Questions of the week: As great a story as it is, is it even possible that the information gathered by the Australasian Antarctic Expedition was worth the human suffering and death?
This is the twenty-ninth in a series on The Harvard Classics; the rest of the posts are available here. Volume XXIX: Voyage of the Beagle
The August issue of National Geographic Magazine has an article about the use of pesticides to poison wildlife in Africa. It is bleak. It seems that some people are poisoning lions and hyenas in retaliation for and prevention of livestock depredation. Poachers and dirt farmers poison elephants and rhinoceroses. And various animals are poisoned to be sold as “bush meat” for human consumption. (Eating poisoned meat doesn’t sound especially safe, but I suppose that if you don’t tell the buyer how the kill was made…) And, predictably, there are tremendous wildlife causalities in the form of collateral damage. Vultures, in particular, are likely to die from eating poisoned carrion.
Driving this disturbing practice is a conflict as old as humanity: competition. A growing human population competes with predators and agricultural pests for resources. It is easy on this side of the Atlantic and this side of a desk job to condemn the killing of lions; but what must life be like for a shepherd whose livelihood is threatened by predators? How many of his sheep must he be willing to lose before he attempts to stop the loses once and for all? And what weapon can he use that is more effective and less dangerous to himself than pesticide? Obviously, using pesticides to poison endangered species is a disgusting and irresponsible practice, but it seems like a natural step in man’s perpetual conflict with the natural world.
When Europeans first came to the Americas, indiscriminate destruction of wildlife was part of the norm as well. Charles Darwin described how early 19th-century South American ranchers hunted pumas (also also commonly known as cougars, mountain lions, panthers, or catamounts): “In an open country, it is first entangled with the bolas, then lazoed, and dragged along the ground till rendered insensible. At Tandeel (south of the Plata), I was told that within three months one hundred were thus destroyed. In Chile they are generally driven up bushes or trees, and are then either shot, or baited to death by dogs.”
By the beginning of the last century, pumas were all but eliminated everywhere east of the Rocky Mountains in the United States. The only puma population left in the eastern US was the critically endangered Florida panther. With such a depleted population, the genetic problems associated with inbreeding have become pronounced in the Florida panthers.
Conservation efforts are underway in both Kenya and Florida. Certain pesticides have been taken off of the market in Kenya, and locals have been hired as rangers and conservationists. In Florida, authorities have released female pumas from Texas to expand the gene pool and put in nighttime speed reduction zones, special roadsides, headlight reflectors, and rumble strips to reduce vehicular collisions with pumas. But the fates of the African lion and the Florida panther are anything but certain. And they will remain uncertain until humans become more mindful of the wide-reaching effects of their actions. As a conservationist quoted in the National Geographic article put it, “wildlife management is people management.”
By the way, tomorrow is the first day of puma (cougar) hunting in Alberta, Canada. The debate about whether sport hunting (together with the licensing fees and game lands management) contribute to healthier and more sustainable animal populations rages on. But Alberta’s got enough of the big cats to get along even if the hunting quota is filled. Assuming those setting the quotas know their business.
Beer of the week: Moosehead Lager – Is there any hunting trophy more iconic than a mounted head? And man, do moose have big heads! From Canada’s oldest independent brewery comes this standard macro lager. It is golden, clear, and fizzy. Neither the taste nor the aroma are anything special, but the little extra hint of malt at the finish makes Moosehead more than just serviceable; it’s actually pretty good. Oh, and this can was among the last to feature the old logo; the company changed it’s packaging this spring.
Reading of the week: The Voyage of the Beagle by Charles Darwin – This excerpt from Chapter XII describes the puma and some of the birds of South America. It is a good example of Darwin’s writing as a naturalist rather than theorist.
Question for the week: Is it possible that the only way to save the African lion and other endangered species is to adopt neo-Malthusian methods? That is, can we only save these animals by taking affirmative steps to reduce the human population?
