The Science of Conjecture: Evidence & Probability Before Pascal by James Franklin

 

                                                                           2015 edition

If the title of this book seems daunting to you, well, then, your instincts are sound. This is not a book for the faint of heart. However, if you're up for an amazing intellectual trek through the high-country (and some low country) of the mind, then you'll find this book a genuinely rewarding experience. I came to the book via a recommendation from Nassim Taleb, and the praise that Taleb expressed for the book proved more than accurate. 

Author James Franklin

Author James Franklin is an Australian mathematician-philosopher, but this description sells him short. The breadth of learning displayed in this volume is truly astonishing. Reading it, you might guess him a linguist, a lawyer, a rhetorician, a medievalist, a scientist, and so on. As the title lets you know, his topics are broad--"evidence" and "probability"--and his account runs from the dawn of Western civ in Egypt and Mesopotamia up to the early modern period of Pascal. (Would that someone write a similar history of Indian and Chinese thought!) Pascal, along with Fermat and Huygens, and a few lesser-known figures, marked a change in thinking about probability when they developed mathematical models and algorithms for calculating the odds (probabilities) involved in stochastic games of chance, such as dice. But as Franklin notes from the beginning of this book, most thinking about probability throughout Western history, including the period after Pascal, addresses probability (and chance) by the use of ordinary language. We see this demonstrated in terms such as "more likely than not," "a preponderance of the evidence," and "beyond reasonable doubt" to give examples of common phrases still used today by lawyers, judges, and juries.

Franklin traces ideas about evidence and probability through the domain of law, which proves the most significant domain for delineating issues of evidence in general and probabilities in particular. But Franklin also addresses developments about these topics in rhetoric, philosophy, theology, moral theology and philosophy (such as the casuistry of the Jesuits), insurance and business law, and natural science. Thinking about issues of evidence and probability has its roots in Greek and Roman thought, but perhaps more noteworthy is the fact that medieval thought and practice analyzed and advanced these concepts greatly. Franklin argues adamantly against many calumnies hurled against medieval thought by modern critics. Many post-classical, pre-Renaissance thinkers receive attention and implicit praise from Franklin for their groundbreaking insights: names like Baldus, Orseme, Duns Scotus, Buridan, Ockham, John of Salisbury, and Nicholas of Autrecourt, and so on. Many of these thinkers and sources were new or only vaguely familiar to me. 

There are times, I must admit, when I found the going a bit slow, although only in the relatively small section on Pascal and his peers did Franklin delve much into math as such. However, I'm quick to forgive Franklin for going a bit deep into the weeds at some points because of the importance of his overall message. Indeed, if you're pressed for time or just want to dip your toe in the get the feel, just read his prefaces (original and 2015), Conclusion, and Epilogue and you will have received a valuable reward for your time. Issues of evidence and the challenge of probabilities are as important and vital to our well-being today as they have been at any time throughout history. Indeed, given the extraordinary human powers that now threaten the entire planet and the continued well-being and survival of humankind as a species, we'd do well to do all we can to educate ourselves about these principles and thereby promote sound decision-making involving issues of evidence and probability. These terms were a part of my everyday concerns as a lawyer who practiced before trial and appellate courts (and administrative tribunals). But issues of evidence and probability have application quite as much (albeit less explicitly so) in our everyday lives. We experience these issues as individuals and as members of groups, for instance, as members of political entities that make decisions that affect our well-being from the level of our neighborhoods to the level of our nation and even now involving our entire world. For instance, we see these issues raised and discussed in great depth and with great concern in our thinking about how to best address climate change,.

Conclusion: The Science of Conjecture is quite an amazing book as a work of scholarship and as a prompt to thought. I would compare in its comprehensiveness and depth to Thomas McEllivey's The Shape of Ancient Thought: Comparative Studies in Greek and Indian Philosophies. High praise indeed!

Thoughts for the Day: Friday 13 November 2020


 

[Quoting Dr. Donald Stuss is the vice president of research at the Rotman Research Institute, Toronto] “Our studies with the elderly show that the one thing you get with age is wisdom. You’ve got this affective responsiveness, this emotional experience. Somebody once asked me whether there was any benefit to aging, because there seems to be little that’s positive about the body’s physical deterioration. I answered by saying that there is something positive, but it’s more spiritual than physical. If your physical stuff gets peeled away, what do you have left? You have your self, your memories, and your history; and those are your spiritual parts. What is a midlife crisis—it’s preparation for aging. Some people say it’s an assessment of ‘What have I done?’ I would say it’s an assessment of ‘Who am I?’ You are forced, if you can meet the challenge of aging, to develop truly as a human being.”

The above gets personal at my age.


Here's the truth: Unless accompanied by a heavy carb load, fat shouldn't make you fat. Carbs are the perpetrator of our obesity and diabetes epidemics.
I believe that the above statement is likely accurate. Damn!

Science, the form of immediacy perception par excellence, can never answer this question. It can never tell us why a sunset or a string quartet is beautiful. This is no argument against science, merely an acknowledgment of its limits.

Writing biography becomes another “impossible profession,” Janet Malcolm’s characterization of psychoanalysis. Impossible, because the person whom biography purports to be about is not altogether a person, as the case an analyst works with is the invisible psyche, brought in by a person. Biographers are ghost writers, even ghost busters, trying to seize the invisible ghosts in the visibilities of a life. A biography that sticks to the facts as closely as it can finds ever clearer traces of the invisible, those symptoms, serendipities, and intrusive inventions that have led, or pursued, the life the biography recounts.
In order to talk about imagination we must use imagination and in order to talk about language we must use language. We can’t get behind them or stand apart from them, as detached observers, as we can with something in the physical world, but must understand them from ‘inside’. That, in fact, is what Barfield set out to do.

Scott Pruitt, A Good Protection Racket, Science, and Playing By the Rules

EPA Administrator Scott Pruitt artistically (and aptly) rendered



One way of looking at government is to see it as a protection racket. Of course, this seems a bit cynical, and I say it with tongue-in-cheek. But, on the other hand, there's some truth in it.

The primary task of governments since we humans first developed governments (which, I suspect, coincides with civilization), has been to protect inhabitants from threats. In the beginning, the most immediate and easily recognized threats came from invaders. Also, governments began to deal with threats from within, such as criminal acts. As civilization progressed and became more complex, so did the threats. For instance, with cities also came epidemic diseases and the need to supply water and waste disposal for masses of people. In response to threats from disease, governments in the 19th century began to provide safe, potable water and sanitary sewers, which addressed a previously unrecognized threat from unseen germs (via Pasteur and Koch's work in the germ theory of disease). And so it goes. The role of government has expanded as people have comes to appreciate sources of threats to our well-being, and as we have developed ways of addressing these threats. (There are other reasons for the growth of government as well, of course.)

So why the "protection racket"? While some threats are open, obvious, and most efficiently addressed by individual action (e.g., look before you cross a busy street), other threats are either less open and obvious and (or) require collective action to mount an effective response.  You may know that Genghis Khan is coming your way, but acting alone--no matter how acute the perception of the risk to your person and how strong your sword arm--is ineffective. And, some threats, like germs, are invisible. And in the 20th and 21st centuries, we now know that contaminants in the air, water, soil, and food supply threaten us, often without our directly perceiving the threat as it presents itself to us. These threats are perhaps even more insidious than more overt threats, like that of violence, because they are less apparent--they are less visible and slower acting, but lethal nevertheless.

So yes, I'm in favor of this "protection racket." I want the government to protect me from covert threats or those that require collective action. I want protection for me, my family, my friends, my fellow human beings, and the world upon which we depend.

In the U.S. and other liberal democracies, we are protected from the threats of contaminations of our air, water, food, and other necessities by laws and regulations. Laws are enacted mostly by our elected representatives (excepting referendums in some jurisdictions). In theory, elected representatives should be acting in accord with the will of the "people," but for a myriad of reasons, some practical and some nefarious, the actions of any legislative body more often reflect the will of special interests rather than the will and best interests of the general public. Also, as a practical matter, a legislative body, such as Congress, can't act effectively to address all of the details needed to protect the public. Some actions require features that are beyond the reach of Congress (or any legislative body). Therefore, Congress and legislatures delegate authority to regulatory agencies.

Regulatory agencies (such as the EPA, discussed in the article below), are governed by the Administrative Procedure Act, adopted by Congress in 1946, to allow Congress to delegate rule-making authority to agencies based on Congressional mandates. Most states have similar laws. The APA creates a system for rule-making and rule-enforcement that his a hybrid of judicial and legislative procedures. Due process, open hearings, notice, and so on are the hallmarks of the APA and its state off-spring. Indeed, given the obvious and egregious pitfalls of the political system, the administrative rule-making and rule-enforcing systems come across as refreshingly rational.

Thus, for instance, when it comes to keeping us safe from impurities in our air, water, and soil (food safety is under the FDA), the EPA is given a mandate by law along with authority to work out the details. In doing so, the agency must follow strict procedures. In fact, once Congres has approved a law that says (in effect), "Keep our air, water, and soil safe for all Americans," it really should become a matter of exploring the limits. What do I mean by "exploring the limits"?

To explore the limits means to move beyond the obvious. For instance, no one (sane) wants to breathe dense smoke day all day (set aside addicted smokers for a moment). No one wants to experience a stream that's treated as an open sewer running along their backyard, and so on. The tougher questions, the limits questions, are where reasonable minds may differ based on value judgments and imperfect knowledge:

1. The nature and seriousness of some threats are not apparent. Deciding "how much" of any contaminant is "too much" is often difficult to determine (causation is not easily identified and isolated). And if we spend money reducing "x," we'll have less money to reduce "y." 
2. Even if we agree on a threat, the best way to minimize the threat may not be easily identified. Should we adopt strict prohibitions? Tax polluters? Require escrow funds? This issue dovetails with the issue of "who pays?" The polluter? The consumer? The taxpayer? The current generation or future generations?

Just these two broad criteria of disagreement allow us to realize how we may disagree. But on the other hand, if we act with rational and scientific prudence and without unwarranted preference in favor of any limited group, we should be able to confine our disagreements within an arena that would allow a fully informed, neutral decision-maker to arrive at a reasoned decision. To enable this, we need access to uninhibited scientific evidence, and we need to allow debate about the underlying scientific assumptions and processes. We would need to have information from all perspectives (stakeholders) rationally presented and without binding preconceptions by a decision-maker. All evidence and arguments should be subject to cross-examination and debate. We must follow the path of science. We must--in some reasonable measure--learn to doubt our doubt, lest we act like contemporaries who mocked Copernicus and Galileo, Newton, Darwin, Pasteur, Einstein--the list could go on almost endlessly. Of course, at some point, we must reach a conclusion sufficient to act (or to justify inaction.  (But note this: absolute certainty is a chimera and quite often a decoy to assure inaction). Openness, large-mindedness, and commitment to a process of testing and renewal are imperative.

I offer all of the above reflection in response the article below, where I find that Mr. Pruitt seems to be flaunting most of the propositions that I argue in favor of. I disapprove of this whole course of conduct. (I'm also sad to note that Mr.Pruitt is a lawyer, for whom the propositions and values stated above should be apparent.)

For a more in-depth consideration of what Mr. Pruitt is up to, read this profile from The New Yorker
A proposed policy would bar the E.P.A. from considering research that doesn't release its raw data for review, blocking some significant work.

The Collapse of Western Civilization: A View from the Future by Naomi Oreskes & Eric M. Conway

Published 2014, "written" in 2393


This book by two historians of science examines our world through the lens of dystopian fiction. For anyone looking for plot and character, go elsewhere. (I think that they’d recommend the work of Kim Stanley Robinson, whom they acknowledge in the book.) This is a “history” book written by historians looking back from the year 2393 while working in the "Second (Neocommunist) People’s Republic of China". But if you want to learn about what we currently know, what we’re currently doing (or not doing), and how our choices extrapolate into the future, then this is a worthwhile book. Anyone who’s read this blog or followed my Tweets knows that climate change and our collective indifference to it and the future that it holds for us is a major concern of mine. I used to say that this concern would be the problem that my daughters and their generation would have to face. Of course, events have proven this expectation false—it’s here now, staring us in the face, as these two authors make abundantly clear. 

Because the authors are both historians of science, they enjoy street cred with both the science community and the larger community, or at least me. (I won’t give my “all knowledge is a matter of history” talk here, but if you need a quick refresher, see below*.) In a previous book, Merchants of Doubt: Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco to Climate Change (New York: Bloomsbury, 2010), these two authors detailed the use of scientists to peddle doubts for the purpose of delaying action on issues of public health from tobacco use to global climate change. They understand not only the science involved in these issues but also the social context in which that science is practiced. Indeed, the whole point of this exercise is the examine how we in the early 21st century have convinced ourselves that we can ignore these issues and blithely continue down our current path toward disaster. They cite a great deal of relevant science, and they extrapolate from our current knowledge about what may happen to this Earth of ours given our current choices. But their observations about canons of knowledge and ideologies are the more unique and insightful aspects of their project. 

Following are some of the more interesting points taken from the book with my commentary following. 

The physical scientists studying these steadily increasing disasters did not help quell this denial, and instead became entangled in arcane arguments about the “attribution” of singular events [floods, fires, storms, droughts & other weather-related events]. Oreskes, Naomi; Conway, Erik M. (2014-06-24). The Collapse of Western Civilization: A View from the Future (p. 7). Columbia University Press. Kindle Edition.

Although they don’t come out and say it (Oreskes is a Harvard professor), the scientific community often lives in an ivory tower. Science is a social enterprise, a human enterprise par excellence, and to ignore this all too human aspect of science is a terrible mistake. To whom much is given (to wit, money for research grants), much is expected. While arguments over standards and protocols are important, they don’t override the greater concerns of society as a whole. 

[M]ost countries still used the archaic concept of a gross domestic product, a measure of consumption, rather than the Bhutanian concept of gross domestic happiness to evaluate well-being in a state. p. 8

It’s good to realize that the word about the utter inadequacy of GNP as a measure of well-being is growing in popularity. But we should move beyond our snapshot in time (as the authors later suggest) and beyond the immediate human world in measuring performance and well-being. 

Though leaders of the scientific community protested, scientists yielded to the demands, thus helping set the stage for further pressure on scientists from both governments and the industrial enterprises that governments subsidized and protected. Then legislation was passed (particularly in the United States) that placed limits on what scientists could study and how they could study it, beginning with the notorious House Bill 819, better known as the “Sea Level Rise Denial Bill,” passed in 2012 by the government of what was then the U.S. state of North Carolina . . . . pp. 11-12

This is a really frightening realization, one that makes Tennessee’s outlawing of the teaching of evolution (as displayed in the Scopes trial) seem trivial. Really, in 21st century America this could happen? This is Orwellian—or more bluntly, Stalinist. (Orwell, of course, decried such lies; Stalin and his cohort used the airbrush on history and reality with abandon.) 

It is difficult to understand why humans did not respond appropriately in the early Penumbral Period, when preventive measures were still possible. Many have sought an answer in the general phenomenon of human adaptive optimism, which later proved crucial for survivors. p. 13

We humans believe that we can always prevail in the last reel. Maybe, but reality isn't a Hollywood movie, and we test the limits at our peril. One thing that the authors don’t do in this “history” is to explore fully all of the likely social, political, and economic disasters that will likely befall humanity if our environment comes crashing down around us. The Four Horsemen of war, famine, pestilence, and death will ride freely throughout the world. To think that we can “innovate” our way out of such a situation amounts to fantasy, mere wishful thinking. 

Even more elusive to scholars is why scientists, whose job it was to understand the threat and warn their societies—and who thought that they did understand the threat and that they were warning their societies—failed to appreciate the full magnitude of climate change. To shed light on this question, some scholars have pointed to the epistemic structure of Western science, particularly in the late nineteenth and twentieth centuries, which was organized both intellectually and institutionally around “disciplines” in which specialists developed a high level of expertise in a small area of inquiry…. While reductionism proved powerful in many domains, particularly quantum physics and medical diagnostics, it impeded investigations of complex systems. Reductionism also made it difficult for scientists to articulate the threat posed by climatic change, since many experts did not actually know very much about aspects of the problem beyond their expertise. pp. 13-14

Again, an important criticism of what is typical of academia: learning more and more about less and less. We can’t afford this now. Specialization and narrow focus can be a tool in some situations, but like many useful tools, it proves useful only for particular occasions. 

Other scientists promoted the ideas of systems science, complexity science, and, most pertinent to our purposes here, earth systems science, but these so-called holistic approaches still focused almost entirely on natural systems, omitting from consideration the social components. Yet in many cases, the social components were the dominant system drivers. It was often said, for example, that climate change was caused by increased atmospheric concentrations of greenhouse gases. Scientists understood that those greenhouse gases were accumulating because of the activities of human beings—deforestation and fossil fuel combustion—yet they rarely said that the cause was people, and their patterns of conspicuous consumption. pp. 15-16

This is a good point about systems and complexity theories. They are better (i.e., more useful in this context) than reductionist theories, but some do divorce humanity from Nature. We are at once a part of Nature and apart from Nature. We now need to appreciate just how much a part of Nature we are. 

Other scholars have looked to the roots of Western natural science in religious institutions. Just as religious orders of prior centuries had demonstrated moral rigor through extreme practices of asceticism in dress, lodging, behavior, and food—in essence, practices of physical self-denial—so, too, did physical scientists of the twentieth and twenty-first centuries attempt to demonstrate their intellectual rigor through practices of intellectual self-denial. These practices led scientists to demand an excessively stringent standard for accepting claims of any kind, even those involving imminent threats. In an almost childlike attempt to demarcate their practices from those of older explanatory traditions, scientists felt it necessary to prove to themselves and the world how strict they were in their intellectual standards. Thus, they placed the burden of proof on novel claims—even empirical claims about phenomena that their theories predicted. This included claims about changes in the climate. p. 16

This is a fascinating insight: scientists as the new ascetics. This helps me understand someone like the late Seth Roberts, who was (in essence) a human climate-change denier. I argued (in comments on his blog) that the judgment was a practical one requiring action, not one that should be governed by abstract principles of skepticism. My thinking came from my knowledge and experience with the common law tradition of making judgments about practical matters of liability. He never made clear (to me anyway) the nature of his skepticism in the face of so much contrary proof. 

Much of the argument surrounded the concept of statistical significance. Given what we now know about the dominance of nonlinear systems and the distribution of stochastic processes, the then-dominant notion of a 95 percent confidence limit is hard to fathom. Yet overwhelming evidence suggests that twentieth-century scientists believed that a claim could be accepted only if, by the standards of Fisherian statistics, the possibility that an observed event could have happened by chance was less than 1 in 20.. . . . We have come to understand the 95 percent confidence limit as a social convention rooted in scientists’ desire to demonstrate their disciplinary severity. p. 17

I’m so glad to read this. I’m untrained in statistics (one of my many shortcomings), but it always seemed to me that the whole enterprise could be quite arbitrary. This is what they say: you have to do better than 1/20 to have “statistical significance”. That’s probably an extremely useful heuristic, but as a “law”, it’s junk. And as a guide for action? Maybe, but maybe not. The appropriateness of any standard depends upon what’s at stake, other sources of confirmation or disproof, and the time scale in which we must judge. In other words, a common law type of judgment: the likelihood of harm, the magnitude of possible harm, and the cost of alternatives serve as benchmarks for decision-making.

Western scientists built an intellectual culture based on the premise that it was worse to fool oneself into believing in something that did not exist than not to believe in something that did. p. 17

Again, which is the worst mistake depends on the practical outcome of the actions taken as a result of the belief or unbelief. The likely practical consequence of a mistake, not the cause of the possible mistake, should guide action. 

To the historian studying this tragic period of human history, the most astounding fact is that the victims knew what was happening and why. Indeed, they chronicled it in detail precisely because they knew that fossil fuel combustion was to blame. Historical analysis also shows that Western civilization had the technological know-how and capability to effect an orderly transition to renewable energy, yet the available technologies were not implemented in time. p. 35

Exactly: how can we be so dumb? (And by dumb, I mean in action, not simply as a means of name-calling.) This is a social-political problem, a problem of persuasion and decision-making of the highest importance. 

The thesis of this analysis is that Western civilization became trapped in the grip of two inhibiting ideologies: positivism and market fundamentalism. p. 35
Yes! 

[T]he overall philosophy is more accurately known as Baconianism. This philosophy held that through experience, observation, and experiment, one could gather reliable knowledge about the natural world, and that this knowledge would empower its holder. Experience justified the first part of the philosophy (we have recounted how twentieth-century scientists anticipated the consequences of climate change), but the second part—that this knowledge would translate into power—proved less accurate. p. 36

This suggests an extreme naiveté in the scientific community and those who support them. 

A key attribute of the period was that power did not reside in the hands of those who understood the climate system, but rather in political, economic, and social institutions that had a strong interest in maintaining the use of fossil fuels. Historians have labeled this system the carbon-combustion complex: a network of powerful industries comprising fossil fuel producers, industries that served energy companies (such as drilling and oil field service companies and large construction firms), manufacturers whose products relied on inexpensive energy (especially automobiles and aviation, but also aluminum and other forms of smelting and mineral processing), financial institutions that serviced their capital demands, and advertising, public relations, and marketing firms who promoted their products. pp. 36-37

While I’m skeptical of conspiracy theories in general, I do believe that the mindset of the "carbon-combustion complex"  (in part held as an intentional choice and in part as a matter of false consciousness or akrasia). In any event, this mindset trumps rational judgment because it's based upon tangible special interests, and it's repeated frequently and widely disseminated. If the propaganda of communist governments had proven anywhere nearly as effective as the promotion of the "carbon-combustion complex" and market fundamentalist ideology, those regimes would probably still be around today. 

[A] large part of Western society was rejecting that knowledge in favor of an empirically inadequate yet powerful ideological system. Even at the time, some recognized this system as a quasi-religious faith, hence the label market fundamentalism. Market fundamentalism—and its various strands and interpretations known as free-market fundamentalism, neoliberalism, laissez-faire economics, and laissez-faire capitalism—was a two-pronged ideological system. pp. 37-38). 

The first prong held that societal needs were served most efficiently in a free market economic system. Guided by the “invisible hand” of the marketplace, individuals would freely respond to each other’s needs, establishing a net balance between solutions (“supply”) and needs (“demand”). The second prong of the philosophy maintained that free markets were not merely a good or even the best manner of satisfying material wants: they were the only manner of doing so that did not threaten personal freedom. p. 38

Another example of good ideas gone bad. A market economy is better than other forms, but it isn't perfect, and as we humans tend to do, we overreached and made the market absolute. 

The ultimate paradox was that neoliberalism, meant to ensure individual freedom above all, led eventually to a situation that necessitated large-scale government intervention. p. 48

This forecast is probably correct. How ironic! 

Period of the Penumbra  The shadow of anti-intellectualism that fell over the once-Enlightened techno-scientific nations of the Western world during the second half of the twentieth century, preventing them from acting on the scientific knowledge available at the time and condemning their successors to the inundation and desertification of the late twenty-first and twenty-second centuries. pp. 59-60

This leads me back to an insight that I’ve had since I started thinking about this world: human power—via technology—has outrun human wisdom. We've set loose a genie that we can’t control. We humans are the Sorcerer’s Apprentice and none but Nature (the Master Wizard, if you will) can restore order. And it will be messy. 

[Naomi Oreskes being interviewed] The nation in which our historian is writing is the Second PRC, because we imagine that after a period of liberalization and democratization, autocratic forces become resurgent in China, justified by the imperative of dealing with the climate crisis. EC [author Erik Conway]: Chinese civilization has been around a lot longer than Western civilization has and it’s survived a great many traumas. While I’m not sure the current government of China is likely to hold up well—the internal tensions are pretty glaring—it’s hard to imagine a future in which there’s no longer a place called China. And as Naomi explains, authoritarian states may well find it easier to make the changes necessary to survive rapid climate change. With a few exceptions, the so-called liberal democracies are failing to address climate change. p. 70

The authors suggest that China will “go renewable” sooner than the West and will adapt more effectively than the Western nations. Maybe. Currently, China is hell-bent on further economic development, and we can see the effect every day in the air quality. [N.B. As I write these words I'm living in China.] The central government currently has the power to make drastic changes, but how drastic and under what conditions would create a major stress test. The assumption of anything less than a Hobbesian state of nature (or the rise of a Leviathan led by someone as bloodthirsty as a Stalin or a Hitler) seems overly optimistic to me if things deteriorate with the speed and to the extent that the authors suggest that it might. 

This was a one-sitting read. It goes along with William (Patrick) Ophuls and Thomas Homer-Dixon on my (electronic) shelf about the challenge of global climate change. I hope that we can prove their “history” false. 

P.S. The NYT article interview tipped me off to Oreskes and her work, and her TED talk on the practice of science.  
* In sum, the history of anything amounts to that thing itself. History is not a social science but an unavoidable form of thought. That "we live forward but we can only think backward" is true not only of the present (which is always a fleeting illusion) but of our entire view of the future: for even when we think of the future we do this by remembering. But history cannot tell us anything about the future with certainly. Intelligent research, together with a stab of psychological understanding, may enable us to reconstruct something from the past; still, it cannot help us predict the future.

Meditations of a Buddhist Skeptic: A Manifesto for the Mind Sciences and Contemplative Practice by B. Alan Wallace



B. Alan Wallace is among the foremost practitioner-teachers of Buddhism today. He reports “while brought up in a Christian household, and even though I found great meaning in the teachings of Jesus, some of the church’s doctrines made no sense to me”. (Kindle Locations 71-72). He grew up in California, Scotland, and Switzerland. He started as an undergrad at UC San Diego and then he transferred to Göttingen in West Germany, moving from an ecology major at UCSD to a primary interest in philosophy and religion at Gottingen, where he studied the Tibetan language and Tibetan Buddhism. Then, instead of finishing his degree (great message for the parents, no doubt), in 1971 (I’m just transitioning from high school to college), he heads to Tibet. For the next 13 years he studied and meditated in the Tibetan Buddhist tradition in India and Europe, and he came to serve as a translator for the Dalai Lama. After this phase of his life, he returned to academia to complete a degree at Amherst College in physics and philosophy of science. After another meditation retreat, he entered graduate studies in religion at Stanford University. He completed his doctorate, focusing his studies on “the interface between Buddhism and Western science and philosophy”. (B. Alan Wallace website). Since then he has taught, written a number of books for both academic and popular audiences, and he continues to teach meditation. Having read several of his works and now in the midst of listening to podcasts of his meditation retreats, I find him one of the most intriguing, no-nonsense, and persuasive teachers of Buddhism active today. 

This book, his most recent “academic” book (2011), addresses topics important to him. One of the attractive aspects of Buddhism to me and to many others, especially those of us coming from Western traditions, is its radical empiricism and willingness to undergo scrutiny. Wallace scrutinizes the Buddhist tradition, but the main target of his skepticism is Western materialism. Wallace is especially critical of academic psychology for its abandonment of the legacy of William James, who valued and promoted introspection as important source of data about the mind. (Indeed, James is obviously in intellectual hero to Wallace, as well as a great many others—including me.) Instead of following the lead of James, psychology turned to Watson’s behaviorism (no mind, just observable behavior), which was wedded to the ideas of 19th century physics. Wallace is uniquely qualified to challenge the citadel of materialism from his background in physics and philosophy of science combined with his experience in Buddhism. 

While critical of Western materialism (we’re just stuff & consciousness a mere by-product of brain activity), Wallace unabashedly asserts the traditional Buddhist view, which includes an emphasis on mind and consciousness as more than just brain activity and where the paranormal (not magic) exists. Wallace makes these assertions as one who has been on the other side of reality from the majority of Western scientists and philosophers who adhere to the simple materialist paradigm. Wallace also notes the importance of ethical behavior in Buddhism and its effect on our perception of the world. This, too, contrasts markedly with the value-free attitude of Western science. Wallace discusses phenomena like “the placebo effect”, which Western science shunts aside without addressing the implications that physically inert substances can effect with body when combined with the non-physical world of information (even false information). Many in the West know to reject Descartes’s dualism of mind and body, but they attempt to go around it by going all body, no mind. But mind—as in the form of information—is a part of our reality. 

In addition to criticizing the materialists, Wallace also criticizes those who sell “mindfulness” as simply the practice of observing what passes through the mind. This is not Buddhism. Buddhist mindfulness involves mindfulness of right conduct, effort, and livelihood, among other things. It’s not just “whatever”, but an attempt to monitor the contents of the mind. 

All of this simply touches the surface of all that Wallace addresses and argues. His appreciation of the history and enterprise of Western science, Western philosophy and psychology, and traditional Buddhism make him a formidable author. Yet, for all of the depth of his analysis and argument, the book is well written and argued so that it’s easy to follow. In short, he’s an outstanding teacher whom I can’t recommend highly enough (this comes from listening to his podcasts as well). If you want to come into the deep end of the pool, you not find many guides as worthwhile as Wallace.

Hacks, Climate Change, Science & Decisions

Charles Krauthammer, hack writer
I don't often read Charles Kruthammer. I perceive him to be a hack, a tool, a shill--in a word, predictable. I say that with some hesitation because I stopped reading him years ago. I now only glance. I don't want to call people with whom I disagree hacks or other demeaning terms because we disagree. After all, I could be wrong. I can fail to learn by ignoring new information and perspectives. But some writers on both the right and the left are too predictable. They bend the facts to fit their perspectives. We all do that do some degree, but at some point, you just have to stop reading. So why did I read Kruthammer today? 

For reasons that sometimes escape me, our local paper of choice, The Hindu, carries columnists from the NYT & WaPo. Do Indians really get Maureen Dowd? In any event, today I read Krauthammer because I suspected he was full of baloney when I read his title: "The myth of settled science". Here's his opening: 

I repeat: I'm not a global warming believer. I'm not a global warming denier. I've long believed that it cannot be good for humanity to be spewing tonnes of carbon dioxide into the atmosphere. I also believe those scientists who pretend to know exactly what this will cause in 20, 30 or 50 years are white coat propagandists.
Let's unpack this. Healthy skepticism, open-mindedness, continuing inquiry: all are hallmarks of good science. However, this scientific agnosticism, like patriotism, if often the last refuge of scoundrals. Flat-earthers and creationists love to spout it, along with climate change deniers. There is a huge body of science upon which we can have no rational disagreement. Science lives in a double-world: both agreed and open to revision. We have to use sound judgment to distinguish the two. 

In matters concerning global climate change and human carbon-loading of the environment, we have to maintain both attitudes. However, we do have to choose on the basis of the best evidence. We have to make decisions on what we believe to be the truth based on empirical evidence. From this we have to discern  the hypothesis most likely to approximate the truth (facts) that will arise in the future. When it's the future we're considering--and it certainly is in this case--we have to constantly revise our theories and understanding. Double that thought when we're talking about the uber-complex world of the biosphere, perhaps the ultimate complex system that evolves over eons and that fluctuates moment-to-moment. 

Krauthammer unleashes a shotgun spray of arguments in an attempt to hit Obama on this issue. We can't know for sure, so we can't say that "The debate is settled. Climate change is a fact."

Yes, we can. 

It's true to say that we're not sure of how fast change will continue to come, how it will affect weather patterns, and so on. We don't know these things with a high degree of certainty. So does this prevent us from acting? No, we act, regardless. We only can choose whether to act in ignorance or by informed and educated science. We are now acting, only foolishly. What Obama and a decisive majority of the science community are recommending is that we act rationally based on the strong consensus of the scientific community. (I know about Freeman Dyson, but isn't there one in every crowd? Einstein didn't accept quantum theory, either. Even geniuses make mistakes.) Climate change is undoubtedly occurring, even though we don't know with certainty its parameters or trajectory.

We need to act according common law standards for torts (harm to others with whom we don't have a contractual relationship). In other words, we need to gaudge the liklihood of harm, the magnitude of the possible harm, the cost of avoiding the harm, and act accordingly. Climate change-deniers (yes, an apt name for them) ignore the context that we should apply to this type of issue and attempt to make it an all-or-nothing proposition. Nice work if you can get it, but don't expect it in serious issues about the future.

We should recall that we on planet earth are running an N=1 experiment. In doing so, we need to remember that we can't run it again, at least not in this iteration of the universe. Therefore, we ought to be pretty damn careful. I don't like the thought of using less energy--energy is eternal delight. But I don't want to mess up the planet permanently. Especially if we do so by paying attention to hacks like Charles Kruthammer.
