Yes, he is!

US President Barack Obama’s First Inauguration Speech, delivered today:

My fellow citizens:
I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors. I thank President Bush for his service to our nation, as well as the generosity and cooperation he has shown throughout this transition.
Forty-four Americans have now taken the presidential oath. The words have been spoken during rising tides of prosperity and the still waters of peace. Yet, every so often the oath is taken amidst gathering clouds and raging storms. At these moments, America has carried on not simply because of the skill or vision of those in high office, but because We the People have remained faithful to the ideals of our forbearers, and true to our founding documents.
So it has been. So it must be with this generation of Americans.
That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.
These are the indicators of crisis, subject to data and statistics. Less measurable but no less profound is a sapping of confidence across our land – a nagging fear that America’s decline is inevitable, and that the next generation must lower its sights.
Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America – they will be met.
On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord.
On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.
We remain a young nation, but in the words of Scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit; to choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free, and all deserve a chance to pursue their full measure of happiness.
In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of short-cuts or settling for less. It has not been the path for the faint-hearted – for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things – some celebrated but more often men and women obscure in their labor, who have carried us up the long, rugged path towards prosperity and freedom.
For us, they packed up their few worldly possessions and traveled across oceans in search of a new life.
For us, they toiled in sweatshops and settled the West; endured the lash of the whip and plowed the hard earth.
For us, they fought and died, in places like Concord and Gettysburg; Normandy and Khe Sahn.
Time and again these men and women struggled and sacrificed and worked till their hands were raw so that we might live a better life. They saw America as bigger than the sum of our individual ambitions; greater than all the differences of birth or wealth or faction.
This is the journey we continue today. We remain the most prosperous, powerful nation on Earth. Our workers are no less productive than when this crisis began. Our minds are no less inventive, our goods and services no less needed than they were last week or last month or last year. Our capacity remains undiminished. But our time of standing pat, of protecting narrow interests and putting off unpleasant decisions – that time has surely passed. Starting today, we must pick ourselves up, dust ourselves off, and begin again the work of remaking America.
For everywhere we look, there is work to be done. The state of the economy calls for action, bold and swift, and we will act – not only to create new jobs, but to lay a new foundation for growth. We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together. We will restore science to its rightful place, and wield technology’s wonders to raise health care’s quality and lower its cost. We will harness the sun and the winds and the soil to fuel our cars and run our factories. And we will transform our schools and colleges and universities to meet the demands of a new age. All this we can do. And all this we will do.
Now, there are some who question the scale of our ambitions – who suggest that our system cannot tolerate too many big plans. Their memories are short. For they have forgotten what this country has already done; what free men and women can achieve when imagination is joined to common purpose, and necessity to courage.
What the cynics fail to understand is that the ground has shifted beneath them – that the stale political arguments that have consumed us for so long no longer apply. The question we ask today is not whether our government is too big or too small, but whether it works – whether it helps families find jobs at a decent wage, care they can afford, a retirement that is dignified. Where the answer is yes, we intend to move forward. Where the answer is no, programs will end. And those of us who manage the public’s dollars will be held to account – to spend wisely, reform bad habits, and do our business in the light of day – because only then can we restore the vital trust between a people and their government.
Nor is the question before us whether the market is a force for good or ill. Its power to generate wealth and expand freedom is unmatched, but this crisis has reminded us that without a watchful eye, the market can spin out of control – and that a nation cannot prosper long when it favors only the prosperous. The success of our economy has always depended not just on the size of our Gross Domestic Product, but on the reach of our prosperity; on our ability to extend opportunity to every willing heart – not out of charity, but because it is the surest route to our common good.
As for our common defense, we reject as false the choice between our safety and our ideals. Our Founding Fathers, faced with perils we can scarcely imagine, drafted a charter to assure the rule of law and the rights of man, a charter expanded by the blood of generations. Those ideals still light the world, and we will not give them up for expedience’s sake. And so to all other peoples and governments who are watching today, from the grandest capitals to the small village where my father was born: know that America is a friend of each nation and every man, woman, and child who seeks a future of peace and dignity, and that we are ready to lead once more.
Recall that earlier generations faced down fascism and communism not just with missiles and tanks, but with sturdy alliances and enduring convictions. They understood that our power alone cannot protect us, nor does it entitle us to do as we please. Instead, they knew that our power grows through its prudent use; our security emanates from the justness of our cause, the force of our example, the tempering qualities of humility and restraint.
We are the keepers of this legacy. Guided by these principles once more, we can meet those new threats that demand even greater effort – even greater cooperation and understanding between nations. We will begin to responsibly leave Iraq to its people, and forge a hard-earned peace in Afghanistan. With old friends and former foes, we will work tirelessly to lessen the nuclear threat, and roll back the specter of a warming planet. We will not apologize for our way of life, nor will we waver in its defense, and for those who seek to advance their aims by inducing terror and slaughtering innocents, we say to you now that our spirit is stronger and cannot be broken; you cannot outlast us, and we will defeat you.
For we know that our patchwork heritage is a strength, not a weakness. We are a nation of Christians and Muslims, Jews and Hindus – and non-believers. We are shaped by every language and culture, drawn from every end of this Earth; and because we have tasted the bitter swill of civil war and segregation, and emerged from that dark chapter stronger and more united, we cannot help but believe that the old hatreds shall someday pass; that the lines of tribe shall soon dissolve; that as the world grows smaller, our common humanity shall reveal itself; and that America must play its role in ushering in a new era of peace.
To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect. To those leaders around the globe who seek to sow conflict, or blame their society’s ills on the West – know that your people will judge you on what you can build, not what you destroy. To those who cling to power through corruption and deceit and the silencing of dissent, know that you are on the wrong side of history; but that we will extend a hand if you are willing to unclench your fist.
To the people of poor nations, we pledge to work alongside you to make your farms flourish and let clean waters flow; to nourish starved bodies and feed hungry minds. And to those nations like ours that enjoy relative plenty, we say we can no longer afford indifference to suffering outside our borders; nor can we consume the world’s resources without regard to effect. For the world has changed, and we must change with it.
As we consider the road that unfolds before us, we remember with humble gratitude those brave Americans who, at this very hour, patrol far-off deserts and distant mountains. They have something to tell us today, just as the fallen heroes who lie in Arlington whisper through the ages. We honor them not only because they are guardians of our liberty, but because they embody the spirit of service; a willingness to find meaning in something greater than themselves. And yet, at this moment – a moment that will define a generation – it is precisely this spirit that must inhabit us all.
For as much as government can do and must do, it is ultimately the faith and determination of the American people upon which this nation relies. It is the kindness to take in a stranger when the levees break, the selflessness of workers who would rather cut their hours than see a friend lose their job which sees us through our darkest hours. It is the firefighter’s courage to storm a stairway filled with smoke, but also a parent’s willingness to nurture a child, that finally decides our fate.
Our challenges may be new. The instruments with which we meet them may be new. But those values upon which our success depends – hard work and honesty, courage and fair play, tolerance and curiosity, loyalty and patriotism – these things are old. These things are true. They have been the quiet force of progress throughout our history. What is demanded then is a return to these truths. What is required of us now is a new era of responsibility – a recognition, on the part of every American, that we have duties to ourselves, our nation, and the world, duties that we do not grudgingly accept but rather seize gladly, firm in the knowledge that there is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task.
This is the price and the promise of citizenship.
This is the source of our confidence – the knowledge that God calls on us to shape an uncertain destiny.
This is the meaning of our liberty and our creed – why men and women and children of every race and every faith can join in celebration across this magnificent mall, and why a man whose father less than sixty years ago might not have been served at a local restaurant can now stand before you to take a most sacred oath.
So let us mark this day with remembrance, of who we are and how far we have traveled. In the year of America’s birth, in the coldest of months, a small band of patriots huddled by dying campfires on the shores of an icy river. The capital was abandoned. The enemy was advancing. The snow was stained with blood. At a moment when the outcome of our revolution was most in doubt, the father of our nation ordered these words be read to the people:
“Let it be told to the future world…that in the depth of winter, when nothing but hope and virtue could survive…that the city and the country, alarmed at one common danger, came forth to meet [it].”
America. In the face of our common dangers, in this winter of our hardship, let us remember these timeless words. With hope and virtue, let us brave once more the icy currents, and endure what storms may come. Let it be said by our children’s children that when we were tested we refused to let this journey end, that we did not turn back nor did we falter; and with eyes fixed on the horizon and God’s grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.
Thank you.  God bless you, and God bless the United States of America.

Hearing is (not necessarily) believing

Someone (let’s call her Alice) tells you that something is true, say the proposition P.  What can you validly infer from that utterance of Alice?  Not that P is necessarily true, since Alice may be mistaken.  You can’t even infer that Alice believes that P is true, since she may be aiming to mislead you.
Can you then infer that Alice wants you to believe that P is true?  Well, not always, since the two of you may have the sort of history of interactions which leads you to mostly distrust what she says, and she may know this about you, so she may be counting on you believing that P is not true precisely because she told you that it is true.  But, you, in turn, may know this about Alice (that she is counting on you not to believe her regarding the truth of P), and she knows that you know, so she is actually expecting you not to not-believe her on P, but to in fact infer either no opinion on P or to believe that P is true.
So, let us try summarizing what you could infer from Alice telling that P is true:

  • That P is true.
  • That Alice believes that P is true.
  • That Alice desires you to believe that P is true.
  • That Alice desires that you believe that Alice desires you to believe that P is true.
  • That Alice desires you to not believe that P is true.
  • That Alice desires that you believe that Alice desires you to not believe that P is true.
  • That Alice desires you to believe that P is not true.
  • That Alice desires that you believe that Alice desires you to believe that P is not true.
  • And so on, ad infinitum.

Apart from life, the universe and everything, you may be wondering where such ideas would find application.   Well, one place is in Intelligence.   Tennent H. Bagley, in his very thorough book on the Nosenko affair, for example, discusses the ructions in CIA caused by doubts about the veracity of the supposed KGB defector, Yuri Nosenko.    Was he a real defector?  Or was he sent by KGB as a fake defector, in order to lead CIA astray with false or misleading information?  If he was a fake defector, should CIA admit this publicly or should they try to convince KGB that they believe Nosenko and his stories?  Does KGB actually want CIA to conclude that Nosenko is a fake defector, for instance, in order to believe something by an earlier defector which CIA may otherwise doubt?  In which case, should CIA pretend to taken in by Nosenko (to make KGB think their plot was successful) or let KGB know that they were not taken in (in order to make KGB believe that CIA does not believe that other earlier information)?  And so on, ad infinitum.
I have seen similar (although far less dramatic) ructions in companies when they learn of some exciting or important piece of competitor intelligence.   Quite often, the recipient company just assumes the information is true and launches itself into vast efforts executing new plans.  Before doing this, companies should explicitly ask, Is this information true?,  and also pay great attention to the separate question, Who would benefit if we (the recipients) were to believe it?
Another application of these ideas is in the design of computer communications systems.   Machines send messages to each other all the time (for example, via the various Internet protocols, whenever a web-page is browsed or email is sent), and most of these are completely believed by the recipient machine.   To the extent that this is so, the recipient machines can hardly be called intelligent.   Designing intelligent communications between machines requires machines able and willing to query and challenge information they receive when appropriate, and then able to reach an informed conclusion about what received information to believe.
Many computer scientists believe that a key component for such intelligent communications is an agreed semantics for communication interactions between machines, so that the symbols exchanged between different machines are understood by them all in the same way.   The most thoroughly-developed machine semantics to date is the Semantic Language SL of the Agent Communications Language ACL of the IEEE Foundation for Intelligent Physical Agents (IEEE FIPA), which has been formalized in a mix of epistemic and doxastic logics (ie, logics of knowledge and belief).   Unfortunately, the semantics of FIPA ACL requires the sender of information (ie, Alice) to believe that information herself.  This feature precludes the language being used for any interactions involving negotiations or scenario exploration.  The semantics of FIPA ACL also require Alice not to believe that the recipient believes one way or another about the information being communicated (eg, the proposition P).  Presumably this is to prevent Alice wasting the time of the recipient.  But this feature precludes the language being used for one of the most common interactions in computer communications – the citing of a password by someone (human or machine) seeking to access some resource, since the citer of the password assumes that the resource-controller already knows the password.
More work clearly needs doing on the semantics of machine communications.  As the example above demonstrates, communication has many subtleties and complexities.

Epideictic arguments

Suppose you are diagnosed with a serious medical condition, and you seek advice from two doctors.  The first doctor, let’s call him Dr Barack, says that there are three possible courses of treatment.   He labels these courses, A, B and C, and then proceeds to walk you methodically through each course – what separate basic procedures are involved, in what order, with what likely side effects, and with what costs and durations, what chances of success or failure, and what likely survival rates.   He finishes this methodical exposition by summing up each treatment, with pithy statements such as, “Course A is the cheapest and most proven.  Course B is an experimental treatment, which makes it higher risk, but it may be the most effective.  Course C . . .” etc.
The other doctor, let’s call him Dr John, in contrast talks in a manner which is apparently lacking all structure. He begins a long, discursive narrative about the many different basic procedures possible, not in any particular order, jumping back and forth between these as he focuses first on the costs of procedures, then switching to their durations, then back again to costs, then onto their expected side effects, with tangential discussions in the middle about the history of the experimental tests undertaken of one of the procedures and about his having suffered torture while a POW in Vietnam, etc, etc.  And he does all this without any indication that some procedures are part of larger courses of treatment, or are even linked in any way, and speaking without using any patient-friendly labelling or summarizing of the decision-options.
Which doctor would you choose to treat you?  If this description was all that you knew, then Doctor Barack would appear to be the much better organized of the two doctors.   Most of us would have more confidence being treated by a doctor who sounds better-organized, who appears to know what he was doing, compared to a doctor who sounds dis-organized.   More importantly, it is also evident that Doctor Barack knows how to structure what he knows into a coherent whole, into a form which makes his knowledge easier to transmit to others, easier for a patient to understand, and which also facilitates the subsequent decision-making by the patient.  We generally have more confidence in the underlying knowledge and expertise of people able to explain their knowledge and expertise well, than in those who cannot.
If we reasoned this way, we would be choosing between the two doctors on the basis of their different rhetorical styles:  we would be judging the contents of their arguments (in this case, the content is their ability to provide us with effective treatment) on the basis of the styles of their arguments.  Such reasoning processes, which use form to assess content, are called epideictic, as are arguments which draw attention to their own style.
Advertising provides many examples of epideictic arguments, particularly in cultures where the intended target audience is savvy regarding the form of advertisements.  In Britain, for instance, the film director Michael Winner starred in a series of TV advertisements for an insurance company in which the actors pretending to be real people giving endorsements revealed that they were just actors, pretending to be real people giving endorsements.   This was a glimpse behind the curtain of theatrical artifice, with the actors themselves pulling back the curtain.  Why do this?  Well, self-reference only works with a knowledgeable audience, perhaps so knowledgeable that they have even grown cynical with the claims of advertisers.   By winking at the audience, the advertisers are colluding with this cynicism, saying to the audience, “we know you think this and we agree, so our advert is pitched to you, you cynical sophisticates, not to those others who don’t get it.”
The world-weary tone of the narration of Apple’s “Future” series of adverts here is another example of advertisements which knowingly direct our attention to their own style.
Apple Future Advertisement – Robots
And Dr Barack and Dr John?  One argument against electing Senator Obama to the US Presidency was that he lacked executive experience.  A counter-argument, made even by the good Senator Obama himself, was that he demonstrated his executive capabilities through the competence, professionalism and effectiveness of his management of his own campaign.   This is an epideictic argument.
There is nothing necessarily irrational or fallacious about such arguments or such modes of reasoning; indeed, it is often the case that the only relevant information available for a decision on a claim of substantive content is the form of the claim.   Experienced investors in hi-tech start-ups, for example, know that the business plan they are presented with is most unlikely to be implemented, because the world changes too fast and too radically for any plan to endure.   A key factor in the decision to invest must therefore be an assessment of the capability of the management team to adjust the business plan to changing circumstances, from recognizing that circumstances have in fact changed, to acting quickly and effectively in response, through to evaluating the outcomes.   How to assess this capability for decision-making robustness?  Well, one basis is the past experience of the team.  But experience may well hinder managerial flexibility rather than facilitate it, especially in a turbulent environment.  Another way to assess this capability is to subject the team to a stress test – contesting the assumptions and reasoning of the business plan, being unreasonable in questions and challenges, prodding and poking and provoking the team to see how well and how quickly they can respond, in real time, without preparation.   In all of this, a decision on the substance of the investment is being made from evidence about the form – about how well the management team responds to such stress testing.   This is perfectly rational, given the absence of any other basis on which to make a decision and given our imperfect knowledge of the future.
Likewise, an assessment of Senator Obama’s capabilities for high managerial office on the basis of his competence at managing his campaign was also eminently rational and perfectly justifiable.   The incoherent nature of Senator McCain’s campaign and the panic-struck and erratic manner in which he responded to surprising events (such as the financial crisis of September 2008) was similarly an indication of his likely style of government; the style here did not produce confidence in the content.  For many people,  the choice between candidates in the US Presidential campaign was an epideictic one.
POSTSCRIPT (2011-12-14):
Over at Normblog, Norm has a nice example of epideictic reasoning:  deciding between two arguments on the basis of how the arguments were made (presented), rather than by their content.  As always with such reasoning – and contrary to much educated opinion – such reasoning can be perfectly rational, as is the case here.
PS2 (2016-09-05): 
John Lanchester in a book review of a book about investor activism gives a nice example of attempting to influence people’s opinions using epideictic means: Warren Buffet’s annual letters to investors in Berkshire Hathaway:

Even the look of the letters – deliberately plain to the point of hokiness, with old-school fonts and layout hardly changed in fifty years – is didactic. The message is: no flash here, only substance. Go to the company’s Web site, arguably the ugliest in the world, and you are greeted by “A Message from Warren E. Buffet” telling you that he doesn’t make stock recommendations but that you will save money by insuring your car with GEICO and buying your jewelry from Borsheims.” (page 78)

PS3 (2017-04-02):
Dale Russakof, in a New Yorker profile of now-Senator Cory Booker, says:

Over lunch at Andros Diner, Booker told me that [fellow Yale Law School student Ed] Nicoll taught him an invaluable lesson: “Investors bet on people, not on business plans, because they know successful people will find a way to be successful.” (page 60)
