Decadence Henry Sidgwick memorial lecture, 1908

In this thought‑provoking lecture, the speaker turns the familiar notion of “decadence” on its head, moving beyond the familiar artistic clichés to explore the idea of national and political decline as a kind of societal senility. Drawing on historical references from Macaulay to Berkeley, he asks why great civilizations appear to age, weaken, and eventually crumble, and whether such a process is inevitable or merely a convenient metaphor. The discussion weaves together philosophy, biology, and politics, suggesting that the same forces that cause individual organisms to age might also shape the fortunes of whole nations.

Delivered in the grand setting of a university hall in 1908, the address balances scholarly rigor with a conversational tone, inviting listeners to question accepted narratives of progress and to consider the hidden forces that may be eroding modern societies. It offers a rich, reflective journey that feels as relevant today as it did over a century ago, making it an engaging listen for anyone curious about the deeper currents that shape history.
