David Quammen Quotes

• “Of course anyone who truly loves books buys more of them than he or she can hope to read in one fleeting lifetime. A good book, resting unopened in its slot on a shelf, full of majestic potentiality, is the most comforting sort of intellectual wallpaper.”

• “Make no mistake, they are connected, these disease outbreaks coming one after another. And they are not simply happening to us; they represent the unintended results of things we are doing. They reflect the convergence of two forms of crisis on our planet. The first crisis is ecological, the second is medical.”

• “People come into our lives and then they go out again. The entropy law, as applied to human relations. Sometimes in their passing, though, they register an unimagined and far-reaching influence, as I suspect Hughes Rudd did upon me. There is no scientific way to discern such effects, but memory believes before knowing remembers. And the past lives coiled within the present, beyond sight, beyond revocation, lifting us up or weighting us down, sealed away--almost completely--behind walls of pearl.”

• “بعد أسبوع من موت آني " ابنة داروين" بينماالصورة لا تزال حاضرة في الذاكرة، كتب داروين مذكرة خاصة قصيرة تسجل القليل من مفاتنها، وعاداتها، وسماتها، ورقصاتها حوله بطول الممشى الرملي، وتدقيقها صعب الإرضاء، وحبها للأطفال الأصغر سنًا، وموهبتها الموسيقية، وحماسها للقواميش والخرائط . كتب داروين أنه فقد هو وايما "زوجته" متعة دارهما وأنيسة وحدتهما في عمرهما المتقدم. لا شك أن الفتاة الصغيرة كانت تدرك لأي مدى كانت محبوبة.
  ثم ينهي داروين ما كتبه بقوله : "فلتحل عليها البركات"، وقد أسقط هذه المرة, على نحو مبهم .. ذكر اسم الرب !”

• “The transmission of SARS, Dwyer said, seems to depend much on super spreaders—and their behavior, not to mention the behavior of people around them, can be various. The mathematical ecologist’s term for variousness of behavior is “heterogeneity,” and Dwyer’s models have shown that heterogeneity of behavior, even among forest insects, let alone among humans, can be very important in damping the spread of infectious disease.
  
  “If you hold mean transmission rate constant,” he told me, “just adding heterogeneity by itself will tend to reduce the overall infection rate.” That sounds dry. What it means is that individual effort, individual discernment, individual choice can have huge effects in averting the catastrophes that might otherwise sweep through a herd. An individual gypsy moth may inherit a slightly superior ability to avoid smears of NPV as it grazes on a leaf.
  
  An individual human may choose not to drink the palm sap, not to eat the chimpanzee, not to pen the pig beneath mango trees, not to clear the horse’s windpipe with his bare hand, not to have unprotected sex with the prostitute, not to share the needle in a shooting gallery, not to cough without covering her mouth, not to board a plane while feeling ill, or not to coop his chickens along with his ducks. “Any tiny little thing that people do,” Dwyer said, if it makes them different from one another, from the idealized standard of herd behavior, “is going to reduce infection rates.”

• “Influenza is caused by three types of viruses, of which the most worrisome and widespread is influenza A. Viruses of that type all share certain genetic traits: a single-stranded RNA genome, which is partitioned into eight segments, which serve as templates for eleven different proteins. In other words, they have eight discrete stretches of RNA coding, linked together like eight railroad cars, with eleven different deliverable cargoes. The eleven deliverables are the molecules that comprise the structure and functional machinery of the virus. They are what the genes make. Two of those molecules become spiky protuberances from the outer surface of the viral envelope: hemagglutinin and neuraminidase. Those two, recognizable by an immune system, and crucial for penetrating and exiting cells of a host, give the various subtypes of influenza A their definitive labels: H5N1, H1N1, and so on. The term “H5N1” indicates a virus featuring subtype 5 of the hemagglutinin protein combined with subtype 1 of the neuraminidase protein. Sixteen different kinds of hemagglutinin, plus nine kinds of neuraminidase, have been detected in the natural world. Hemagglutinin is the key that unlocks a cell membrane so that the virus can get in, and neuraminidase is the key for getting back out. Okay so far? Having absorbed this simple paragraph, you understand more about influenza than 99.9 percent of the people on Earth. Pat yourself on the back and get a flu shot in November. At”

• “What do we measure when we measure time? The gloomy answer from Hawking, one of our most implacably cheerful scientists, is that we measure entropy. We measure changes and those changes are all for the worse. We measure increasing disorder. Life is hard, says science, and constancy is the greatest of miracles.”

• “لم تكن إيما تشاركه اهتماماته الفكرية، لم تكن تشاركه ترفّعه عن الدين أو نظرته المادية للعالم، كانت لا تزال تعبد إلهًا مسيحيًا وتشعر بالقلق بشأن روح زوجها، أما هو فكان من ناحيته يحبها حبًا جمًا. لم يستطع التظاهر بأنه يصادق على معتقاداتها، أو يتقبل أعمق أشجانه (كفقدان ابنته آني) وأمراضه بروح من الإذعان التقي، كما كانت إيما تريده أن يفعل. لكنه كان يبجّل ما فيها من خير وكان حساسًا لمشاعرها. ظل أربعين عامًا يحتفظ في مكان ما وسط الحقائب والأوراق بذلك الخطاب الجاد الذي كتبته له قبيل زواجهما، عندما سمعت اعترافه بأفكاره الجامحة المهرطقة. كتبت في إصرار: "لا تظن أن هذا ليس من شأني، وأنه لا يحمل الكثير من الأهمية لي." كتبت له إيما أن هذا أمر له أهميته، وعارضت رأيه بحزم، لكن بحب. فكل ما يخصه يخصها هي أيضًا، وكتبت له قائلة: "سأكون أشد تعاسة لو اعتقدت أنه لا ينتمي أحدنا للآخر إلى الأبد." ومن وقتها ظلت على مر السنين على أملها في أن يكونا معًا إلى الأبد، في الحياة الآخرة، لكن دون أن تلقى أي تأكيد منه لهذا الأمل. لم يكن في استطاعة داروين إلا أن يتعاطف معها، أو يتجنب الموضوع. لم يكن من طبعه أن يكذب، لكنه في وقت ما خط ملحوظة في نهاية خطابها، عُثر عليها بين أوراقه الأخرى، قال فيها:
  
  "عندما أموت، فلتعرفي أني كثيرًا ما قبّلت هذا الخطاب وبكيت.”

• “Ebola is a zoonosis. So is bubonic plague. So was the so-called Spanish influenza of 1918–1919, which had its ultimate source in a wild aquatic bird and, after passing through some combination of domesticated animals (a duck in southern China, a sow in Iowa?) emerged to kill as many as 50 million people before receding into obscurity.”

• “Our findings highlight the critical need for health monitoring and identification of new, potentially zoonotic pathogens in wildlife populations, as a forecast measure for EIDs.” That sounds reasonable: Let’s keep an eye on wild creatures. As we besiege them, as we corner them, as we exterminate them and eat them, we’re getting their diseases.”
