“Now is our last chance to get the future right.”
When you’re in a mood for a bit of philosophy and history, get comfy and listen to A Short History of Progress, Part One (real audio, ~50 mins), a wonderful, eloquent lecture by Ronald Wright which starts to ask how and why we make progress as a civilization. There is one giant and disturbing insight that connects capitalism to the emergence of homo sapiens.
The rest of the lectures and the book are also available.
