Thirty years ago, John Horgan had a dream—or rather a nightmare. Here and there, scientists were saying that all the major problems of the universe had essentially been solved, and that the work of the future was just going to be filling in the details of what we already knew.

But those voices were largely drowned out in the generation of scientists who came of age promoting radical new ideas that they claimed would push their disciplines far beyond what was then-currently known. Despite their creators’ claims, however, ideas like string theory, quantum consciousness, and chaos theory, were unable to generate actual testable ideas and inventions.

Had scientific progress stalled? Is it possible that there are real limits on what humans can ever know because of the type of beings that we are? This was the thesis of John’s book, The End of Science, which was published in 1996.

The book was instantly controversial, and he was fired from Scientific American because of it. And yet in the intervening 30 years, many of the exact same people he had profiled are still promoting the same unproductive ideas.

Is it accurate to say that science is stalled out though? That’s why I wanted to talk with John about the book, and where he sees things in 2026, especially now that one of America’s two major parties has rebuilt itself around attacking science and secular knowledge.
