Essay
Every time we go online, AI is there. Whether we want it to or not, AI is becoming part of our everyday lives. In many cases, it is incredibly convenient—the machine knows! In other situations, it’s enormously unsettling—how can a machine know that? And then there’s the question: Are there other forms of intelligence besides AI? There is the intelligence of life. Ernst Zürcher knows this. Trees are living witnesses to annual rhythms, pulsations of cosmic forces. They are also …

Essay
Discussions on war and geopolitics are the most polarizing. This polarization hinders dialogue and sometimes even thinking itself. Could it be that our cognitive processes shape our perceptions of war and peace? A plea for multiperspectivism, using the war in Ukraine as an example. In Western public discourse and the media, there’s a phrase that’s become widely accepted: the war in Ukraine is “an unprovoked war of aggression.” The war is said to be the result of the imperialist ambitions …

Nakba Day—the Memory of the Catastrophe—is observed annually on May 15. It commemorates the Nakba, the violent uprooting and expulsion of more than 700,000 Palestinians, following the establishment of the State of Israel in 1948.

Column
A tree’s life story is inscribed in its core. Each year, a new layer of cells forms around the existing wood. It’s thickness and color tell the story of weather and circumstances. Was it windy, wet, particularly hot that year? Was there a fire? A drought? It’s all written in the layers of wood, if you know how to read it, and enclosed in a layer of bark.

Column
I asked for a receipt for the far-too-expensive visit to the small Ethiopian farmstead. The men just stared blankly at me. Was I getting ripped off? I sounded like my mother and realized that her way of dealing with things had shaped me. I tried to smooth things over with wit and charm, and without drawing attention to my womanhood. After all, women certainly don’t have much say in matters here. Secretly, I thought the guide was arrogant before realizing that he came from the line of clan leaders. And eventually, I sat in a young wife’s hut and listened to her singing, as beautiful as the savanna wind at 5 p.m.

Letter
Reflections and reader responses to the interview by Frode Barkved with Ukranian Serhii Kopyl, “Everything I Own, I Carry with Me.” Winston Churchill wrote that the first casualty of war is truth, speech. Indeed, violence silences and polarizes. We welcome here an open conversation about this most terrible war in Europe since 1945. Renatus Derbidge Questions We Can No Longer Avoid To me, this article is among the best I have read in Das Goetheanum in a long time. Not …

History
Marginalia on Rudolf Steiner’s Life and Work 39. As a talented editor, Fritz Koegel found his calling at the Nietzsche Archive. He became embroiled in a conflict with Elisabeth Förster-Nietzsche, a conflict Rudolf Steiner was also drawn into. Career setbacks, artistic endeavors, and a family life overshadowed by depression lead to early tragedies. When Rudolf Steiner visited the Nietzsche Archive in Naumburg for the first time on May 26, 1894, along with his colleagues from the archive and the poet …
