The bet was on, and it was over the fate of humanity. On one side was the Stanford biologist Paul R. Ehrlich. In his 1968 best seller, The Population Bomb, Ehrlich insisted that it was too late to prevent a doomsday apocalypse resulting from overpopulation. Resource shortages would cause hundreds of millions of starvation deaths within a decade. It was cold, hard math: The human population was growing exponentially; the food supply was not. Ehrlich was an accomplished butterfly specialist. He knew that nature did not regulate animal populations delicately. Populations exploded, blowing past the available resources, and then crashed.

In his book, Ehrlich played out hypothetical scenarios that represented “the kinds of disasters that will occur.” In the worst-case scenario, famine rages across the planet. Russia, China, and the United States are dragged into nuclear war, and the resulting environmental degradation soon extinguishes the human race. In the “cheerful” scenario, population controls begin. Famine spreads, and countries teeter, but the major death wave ends in the mid-1980s. Only half a billion or so people die of starvation. “I challenge you to create one more optimistic,” Ehrlich wrote, adding that he would not count scenarios involving benevolent aliens bearing care packages.

To feel relief at my mother’s being dead was once unthinkable, but then the news came from Ireland. It would have crushed her. An immigrant’s daughter, my mother lived with an eye cast back to the old country, the land against which she measured every virtue. Ireland was heaven to her, and the Catholic Church was heaven’s choir. Then came the Ryan Report.

Not long before The Boston Globe began publishing its series on predator priests, in 2002—the “Spotlight” series that became a movie of the same name—the government of Ireland established a commission, ultimately chaired by Judge Sean Ryan, to investigate accounts and rumors of child abuse in Ireland’s residential institutions for children, nearly all of which were run by the Catholic Church.

PHILADELPHIA—If the new rules of politics post-2016 were to hold up, the official launch rally Joe Biden held here on Saturday would mean that he is in trouble: The crowd wasn’t huge, was largely white and older, and, for the most part, only really got into it when he mentioned Barack Obama or Donald Trump.

Yet Biden’s high-and-getting-higher poll numbers, the early fundraising success that has surprised even his own aides, and the enthusiastic responses I heard from supporters who came out on a hot afternoon to see him don’t show a candidate in much trouble at all. Biden’s campaign is a bet: that in the four years since Trump launched his campaign, the country hasn’t changed, the Democratic Party hasn’t changed, and politics hasn’t changed.

At first glance, the hagfish—a sinuous, tubular animal with pink-grey skin and a paddle-shaped tail—looks very much like an eel. Naturalists can tell the two apart because hagfish, unlike other fish, lack backbones (and, also, jaws). For everyone else, there’s an even easier method. “Look at the hand holding the fish,” the marine biologist Andrew Thaler once noted. “Is it completely covered in slime? Then, it’s a hagfish.”

Hagfish produce slime the way humans produce opinions—readily, swiftly, defensively, and prodigiously. They slime when attacked or simply when stressed. On July 14, 2017, a truck full of hagfish overturned on an Oregon highway. The animals were destined for South Korea, where they are eaten as a delicacy, but instead, they were strewn across a stretch of Highway 101, covering the road (and at least one unfortunate car) in slime.

Saturday Night Live opened the last episode of its 44th season with a sketch featuring Alec Baldwin as Donald Trump, sitting in the Oval Office, telling a few jokes, and then singing a song with a coterie of characters from his administration. That might sound like par for the course for this show, but it was actually Baldwin’s first appearance in character since March, when SNL mocked the president’s reaction to the Mueller report. Almost three years into a presidency one could charitably describe as newsworthy, the best this show could come up with for a season finale was Trump singing Queen’s “Don’t Stop Me Now” and shimmying behind his desk, as if daring the audience to, well, stop him.

The brewing news going into last night’s episode was that Kate McKinnon, the indisputable star of this era of SNL, might be departing for greener pastures. Her contract is up as of now and she may be ready to move on to movie stardom like countless breakout actors before her. But if this was her last hurrah, there was little sign of it, and certainly no grand send-off like the ones Kristen Wiig or Bill Hader got. Instead, there was the same slightly lackluster mix of topical material and unmemorable goofy sketch writing that has defined the show in recent years. SNL has survived for so many decades by knowing when to pull the trigger on a revamp, and Baldwin’s dismal karaoke work last night was the surest sign yet that something needs to change.

In my long career as an academic jack-of-all-trades, I sometimes teach law students Jurisprudence—that is, Philosophy of Law. The course begins with the question “What is law?” and its corollary, “What is lawlessness?”

The latter comes in two flavors. The first is anarchy—Hobbes’s “war of all against all,” a Mad Max moonscape in which only stealth and brute force provide even a semblance of safety. Such situations existed for millennia and, though relatively rare, exist in remote parts of the globe today.

But there is an authoritarian lawlessness that is far more common in the 21st century, and next time I teach the course, I will have the most precise example of this second version I have ever seen: the dispute over 26 U.S. Code § 6103(f)(1), which reads: “Upon written request from the chairman of the Committee on Ways and Means of the House of Representatives, the chairman of the Committee on Finance of the Senate, or the chairman of the Joint Committee on Taxation, the Secretary [of the Treasury] shall furnish such committee with any return or return information specified in such request,” subject only to a requirement that the return be considered in closed session.

Commencement speakers have a routine: a few words of encouragement, a good—or maybe not so good—joke, and a bit of advice. But this year, Robert F. Smith, the billionaire founder of the private equity firm Vista Equity Partners, who delivered the commencement address on Sunday morning at Morehouse College, a historically black college in Atlanta, took a different approach.

“You great Morehouse men are bound only by the limits of your own conviction and creativity,” Smith told the soon-to-be graduates of the venerated HBCU (historically black college or university). Smith then did something astonishing: He did what he could to make that actually true, telling the class that his family would be eliminating the graduates’ student debt. The crowd, as expected, went wild.

On Saturday, Representative Justin Amash became the first Republican member of Congress to suggest that President Trump should be impeached for his misdeeds, a stand that puts him at odds with the GOP and risks his future in the party.

For nine years, the libertarian-leaning Michigander has been an unusually principled and independent-minded pol, breaking partisan ranks whenever he felt the Constitution demanded it. He used Twitter to lay out his conclusions about Special Counsel Robert Mueller’s report, Attorney General William Barr’s characterizations of that report, the portions that have not been released to the public, and his belief that many of his fellow lawmakers are not fully informed about the matter.

Many, many Christians believe they are subject to religious discrimination in the United States. A new report from the Public Religion Research Institute and Brookings offers evidence: Almost half of Americans say discrimination against Christians is as big of a problem as discrimination against other groups, including blacks and minorities. Three-quarters of Republicans and Trump supporters said this, and so did nearly eight out of 10 white evangelical Protestants. Of the latter group, six in 10 believe that although America once was a Christian nation, it is no longer—a huge jump from 2012.

Polling data can be split up in a million different ways. It’s possible to sort by ethnicity, age, political party, and more. The benefit of sorting by religion, though, is that it highlights people’s beliefs: the way their ideological and spiritual convictions shape their self-understanding. This survey suggests that race is not enough to explain the sense of loss some white Americans seem to feel about their country, although it’s part of the story; the same is true of age, education level, and political affiliation. People’s beliefs seem to have a distinctive bearing on how they view changes in American culture, politics, and law—and whether they feel threatened. No group is more likely to express this fear than conservative Christians.

To the six women currently running in the 2020 presidential race, I offer this advice: Study German Chancellor Angela Merkel, the world’s most successful living politician, on the basis of both achievement and longevity. Now in her 14th year as chancellor of Europe’s powerhouse, Merkel has upended the rules of the male-dominated German political culture, and transformed her country along the way.

Without fanfare, Merkel made German society friendlier to the ambitions of women. Merkel’s handpicked successor to lead the Christian Democratic Union is a woman, there are six other women in her cabinet, and women abound in her circle of advisers. Alexander Gauland, the leader of Germany’s far-right political party AfD, recently asked, “Are there no men left in the CDU?” The party still has quite a few men; they just don’t run it any longer.
