Michael Sugrue, Whose Philosophy Lectures Were a YouTube Hit, Dies at 66

The college lecturer, in a uniform of rumpled khakis and corduroy blazer, paces on a small stage, head down. “The lectures you’re about to see,” he says in introducing a series of talks, videotaped in somewhat hokey lo-fi style in 1992, “cover the last 3,000 years of Western intellectual history.”

The lecturer, Michael Sugrue, would go on to teach Plato, the Bible, Kant and Kierkegaard to two generations of undergraduates, including for 12 years at Princeton, without ever publishing a book — an academic who hadn’t “really had a career,” as he told The American Conservative after retiring in 2021.

But that same year, in the depths of the pandemic, Dr. Sugrue uploaded his three-decade-old philosophy lectures to YouTube, where many thousands of people whose aperture on the world had narrowed to a laptop screen discovered them. His talk on the Stoic philosopher Marcus Aurelius, in particular, seemed to fit the jittery mood of lockdown, when many people sought a sense of self-sufficiency amid the chaos of the outside world. It has now been viewed 1.5 million times.

“The only matter of concern to a wise and philosophic individual is the things completely under your control,” Dr. Sugrue lectured, iterating Stoic thought. “You can’t control the weather, you can’t control other people, you can’t control the society around you.”

Dr. Sugrue, who became an internet phenomenon through word of mouth — without publicity or viral links from social media — after an academic career spent in near obscurity, died on Jan. 16 in Naples, Fla. He was 66.
