The Ezra Klein Show

Consciousness is this amazing, mind-bending riddle. It’s the only thing any of us truly knows. We experience everything else in life through it. And yet we barely understand it. We don’t know what it’s made of or how it works or why it exists. But scientists and theorists have been trying to answer those questions, and have made some startling discoveries. The science writer Michael Pollan, known for books like “The Omnivore’s Dilemma” and “How to Change Your Mind,” spent five years on the vanguard of this research. And his new book, “A World Appears: A Journey Into Consciousness,” shows that the closer you look at consciousness, the weirder it gets. I asked Pollan to walk through some of the places his mind wandered on this journey — including the role of the body and feelings in consciousness, fascinating studies that provide evidence for plant sentience, the researchers who have abandoned their old theories after trying psychedelic drugs, and the possibility that consciousness may not emerge from inside us at all. “I’ve entered this ‘never say never’ realm with this research,” Pollan told me.

Is Trumpism crashing on the shoals of the Iran war? That is what Christopher Caldwell thinks. Caldwell is a prominent thinker on the right. He’s a contributing editor at the conservative publication the Claremont Review of Books,and he’s one of the people who’ve been trying to define, and even craft, a coherent Trumpism. So his recent article in The Spectator, “The End of Trumpism,” sparked a lot of debate on the right. At the core of this debate are some fundamental questions that I think remain unresolved, despite Trump’s decade-long dominance of the Republican Party: What is Trumpism? Is there Trumpism, or is there just Donald Trump? Caldwell is a contributing writer for Times Opinion and the author of “The Age of Entitlement: America Since the Sixties.” In this conversation, he explains how he understood Trumpism as a movement of “democratic restoration” — and why he believes the Iran war betrays that. And I ask him why he sees the seams of Trump’s base fraying, despite polling that suggests otherwise.

Iran has currently shut off more than 10 percent of the world’s oil supply. If that goes on for a lot longer — or if the war escalates to include more strikes on energy infrastructure in the region — the price of oil could go through the roof, and the damage to the global economy could be catastrophic. So what would that look like? What tools does the United States have to avert it? And how is this crisis already reverberating in countries around the world? Jason Bordoff is the founding director of the Center on Global Energy Policy at Columbia University and a founding dean of the Columbia Climate School. He served as a special assistant to President Barack Obama and senior director for energy and climate change on the National Security Council. In this conversation, Bordoff answers all my questions about the crisis so far and how things could spin out from here, the strategic positioning of the United States, Europe, Iran, Russia and China, the developing countries likely to suffer the most and the lessons the world might take from this.

Naomi Klein saw where our politics was headed before most people on the left. Her 2023 book “Doppelganger: A Trip Into the Mirror World” is hard to describe. But among other things, it traces the new coalitions Klein saw forming on the right, the ways they were co-opting issues long associated with the left, and finding huge audiences and influence outside existing institutions. The people and coalitions that Klein wrote about run our world now. We are all living in the mirror world. As she put it, it’s “doppelgangers at the wheel.” So I wanted to have Klein on the show to help understand how that happened, what the left failed to see at the time and the lessons the left should take from it now. As Klein told me: “The thing about doppelgangers is, in literature, they’re always a message telling you a warning: You have to look at yourself. There’s something about yourself that you’re not seeing.” Note: We recorded this episode before the war in Iran.

The Trump administration miscalculated how Iran would respond to this war. And the United States, Iran and Israel were brought to the brink of war in the first place because of a whole series of misjudgments and miscalculations going back decades. Ali Vaez is the Iran project director at the International Crisis Group. He was involved in the negotiations that led to the 2015 nuclear deal, and is in fact himself a nuclear scientist. He’s also an author of “How Sanctions Work: Iran and the Impact of Economic Warfare.” In this conversation, Vaez explains how over 47 years the United States, Israel and Iran came to one another as threats, and why so many efforts to thaw relations failed. It’s the briefing on Iran that Trump should have received before he decided to go to war.
