In authoritarian societies, cultural institutions tend to become ideological proxies - think of the National Ballet in Cuba or the East German gymnastics team.

You may or may not agree with Obama's policy prescriptions, but they are, by and large, serious attempts to deal with the biggest issues we face: a failing health care system, oil dependency, income stagnation, and climate change.

The invasion of Iraq was, in ways that have since become hard to dispute, a terrible mistake.

To Trump, being a billionaire means plating everything in gold and slapping his name everywhere in huge block letters. It means that he gets to say whatever pops into his head and never has to say he is sorry.

I think part of the reason anyone goes into journalism is to get a response to what they write.

Members of the middle class do not have to worry about falling off $250,000 sailboats because they don't have $250,000 sailboats to fall off of.

Book collecting is a largely solitary, mostly male, and completely absorbing activity.

Libertarianism, the political philosophy of rugged individualism, ought to hold a natural appeal to tolerant, anti-statist, free-trade conservatives who deplore the turn taken by the party of Abraham Lincoln toward racial prejudice, authoritarianism, and mercantilism.

Despite all the Internet has done to make prices transparent and bibliographic information universal, you can still find - at book sales and thrift shops, auctions and even fancy dealers - unrecognized or underpriced rarities. Getting something valuable for cheap is the basic, greedy thrill of book collecting.

Trade, tourism, cultural exchange, and participation in international institutions all serve to erode the legitimacy of repressive regimes.

As a political party, the Libertarians have always been more party than political.

People tend to throw up hands at Michael Jackson's multifarious bizarreness. But is it really so strange? The boy was forced to work by a cruel and physically abusive father starting at the age of 7.

Only when legislators judge that the risk of continuing to support Trump outweighs the risk of abandoning him will they begin to jump ship.

All kinds of gambling, from bingo to baccarat, are benign entertainment for most people, dangerously addictive to a few, and capable of breeding unwanted side effects for society.

Like other forms of gambling, wagering on the Internet isn't illegal because it's bad. It's bad because we've chosen to make it illegal.

Because conscription appeals to essentially no one, the United States has lived with the All-Volunteer Force since the end of the Vietnam War.

Where the grifter is shameless, the grafter shrinks from exposure, which could only endanger the racket. He is greedy but not creatively ambitious. He toils in mundane self-dealing, insider trading, bribe taking, witness tampering, and other forms of workaday corruption.

If the creators of cartoons are intentionally or unintentionally giving children the idea that gay people are part of the big, happy human family, that's a good thing, not a bad one.

The first conversation I ever had about the Internet was in 1993 with Robert Wright, who was then a colleague at the 'New Republic.'

Thanks to Twitter, I learn about the revolutions in the Middle East via Arab activists and writers, not just from American foreign correspondents.

In authoritarian societies, cultural institutions tend to become ideological proxies - think of the National Ballet in Cuba or the East German gymnastics team.

Academic Marxists were never going to be convinced that anything that happened in the real world could invalidate their belief system. Utopians of the Right, libertarians are just as convinced that their ideas have yet to be tried and that they would work beautifully if we could only just have a do-over of human history.

As with the government failures that made 9/11 possible, neglecting to prevent the crash of '08 was a sin of omission - less the result of deregulation per se than of disbelief in financial regulation as a legitimate mechanism.

The best thing you can say about libertarians is that because their views derive from abstract theory, they tend to be highly principled and rigorous in their logic.

The worst thing you can say about libertarians is that they are intellectually immature, frozen in the worldview many of them absorbed from reading Ayn Rand novels in high school. Like other ideologues, libertarians react to the world's failing to conform to their model by asking where the world went wrong.

Of the alternatives we face in controlling long-term spending growth, moving Medicare to a voucher system seems only mildly unfortunate - and nothing as compared with a debt-driven economic crisis that could stem from inaction.

While 'The Wire' feels startlingly lifelike, it is not, in fact, a naturalistic depiction of ghetto life. That kind of realism better describes an earlier miniseries of Simon's, 'The Corner,' which was based on the book of the same title that he and Ed Burns wrote, set in the same Baltimore ghetto.

What ultimately makes 'The Wire' uplifting amid the heartbreak it conveys is its embodiment of a spirit that Barack Obama calls 'the audacity of hope.' It is filled with characters who should quit but don't, not only the boys themselves but teachers, cops, ex-cops, and ex-cons who lose their hearts to them.

Israel never meant to take over the West Bank and Gaza - it got stuck with them after the 1967 war.

American liberals are an external part of Israel's conscience, and when it disdains them, it becomes a harder and more isolated place. The support that Israel has gained from millenarian American conservatives is no substitute, in part because such allies aren't persuasive global advocates for Israel.

Objecting to someone because of his religious beliefs is not the same thing as prejudice based on religious heritage, race, or gender.
