Medicine often focuses only on the physical act of living -- breathing in and out, keeping the heart beating. But human life is more than the functioning of the moving parts. Although healthcare may be the only requirement for a brain-dead accident victim on life support, it is not the only requirement for the rest of us. To live, we need food, we need shelter, we need companionship and work, and hundreds of other material and spiritual requirements. Healthcare is a necessity -- and after a car accident, or during a flu infection, it may be the most important necessity. But it is not the only requirement for life.

When people talk about a 'right' to healthcare, they mean an entitlement to healthcare. They mean that unlike other goods and services that must be earned through individual work or trade, healthcare should be provided for free.

Medicine is not the only industry that fulfills a necessity for life, so what entitles us to the products of this particular industry, and not others? Why not food or clothes? And why not those products that provide a good life -- feather beds or paintings or tickets to the movies? Or are we entitled to those as well?

The issue goes far beyond healthcare. It is a question of what the government's role should be in providing for its citizens. Should the government collect taxes to provide citizens with whatever goods and services they deem 'necessary?' Or is it the responsibility of individual citizens to work for whichever products and services they can independently earn -- with the government existing to secure their freedom to pursue these ends?

Further research by [Fabrizio] Benedetti [of the University of Turin] and others showed that the promise of treatment activates areas of the brain involved in weighing the significance of events and the seriousness of threats. "If a fire alarm goes off and you see smoke, you know something bad is going to happen and you get ready to escape," explains Tor Wager, a neuroscientist at Columbia University. "Expectations about pain and pain relief work in a similar way. Placebo treatments tap into this system and orchestrate the responses in your brain and body accordingly."

[O]ne way that [a] placebo aids recovery is by hacking the mind's ability to predict the future. We are constantly parsing the reactions of those around us--such as the tone a doctor uses to deliver a diagnosis--to generate more-accurate estimations of our fate. One of the most powerful placebogenic triggers is watching someone else experience the benefits of an alleged drug. Researchers call these social aspects of medicine the therapeutic ritual.

Benedetti has helped design a protocol for minimizing volunteers' expectations that he calls "open/hidden." In standard trials, the act of taking a pill or receiving an injection activates the placebo response. In open/hidden trials, drugs and placebos are given to some test subjects in the usual way and to others at random intervals through an IV line controlled by a concealed computer. Drugs that work only when the patient knows they're being administered are placebos themselves.

It is true that the climate panel published a flawed overestimate of the melting rate of debris-covered glaciers in the Himalayas, and used information about the Netherlands provided to it by the government, which was later found to be partly inaccurate. In addition, e-mail messages stolen from the University of East Anglia in Britain showed that scientists besieged by an onslaught of hostile, make-work demands from climate skeptics may not have adequately followed the requirements of the British freedom of information law. But the scientific enterprise will never be completely free of mistakes.

What is important is that the overwhelming consensus on global warming remains unchanged.

Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus...

It would be an enormous relief if the recent attacks on the science of global warming actually indicated that we do not face an unimaginable calamity requiring large-scale, preventive measures to protect human civilization as we know it.

Of course, we would still need to deal with the national security risks of our growing dependence on a global oil market dominated by dwindling reserves in the most unstable region of the world, and the economic risks of sending hundreds of billions of dollars a year overseas in return for that oil. And we would still trail China in the race to develop smart grids, fast trains, solar power, wind, geothermal and other renewable sources of energy — the most important sources of new jobs in the 21st century.

Because these and other effects of global warming are distributed globally, they are difficult to identify and interpret in any particular location. For example, January was seen as unusually cold in much of the United States.

Similarly, even though climate deniers have speciously argued for several years that there has been no warming in the last decade, scientists confirmed last month that the last 10 years were the hottest decade since modern records have been kept.

Simultaneously, changes in America’s political system — including the replacement of newspapers and magazines by television as the dominant medium of communication — conferred powerful advantages on wealthy advocates of unrestrained markets and weakened advocates of legal and regulatory reforms. Some news media organizations now present showmen masquerading as political thinkers who package hatred and divisiveness as entertainment. And as in times past, that has proved to be a potent drug in the veins of the body politic. Their most consistent theme is to label as “socialist” any proposal to reform exploitive behavior in the marketplace.

From the standpoint of governance, what is at stake is our ability to use the rule of law as an instrument of human redemption.

Obamacare represents the government annexation of "one-sixth of the U.S. economy" – i.e., the equivalent of the entire British or French economy, or the entire Indian economy twice over. Nobody has ever attempted this level of centralized planning for an advanced society of 300 million people. Even the control-freaks of the European Union have never tried to impose a unitary "comprehensive" health care system from Galway to Greece. The Soviet Union did, of course, and we know how that worked out.

The economy is a wholly owned subsidiary of the environment, not the other way around.

Marx and Lenin were brilliant intellectuals, and Mr. Obama may be as well. But all share a fundamental lack of understanding about how an economy based on the division of labor works, and how trade, sound money, and private property rights all serve to promote peaceful, harmonious social cooperation as evinced by this division of labor. As such, all fail to see how government policy errors can cause economic disasters, such as the 1930s or today's mess -- these leaders, like most members of the political class, fail to apprehend how wealth is created, and how this process is stultified via government interventions.
