What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Michael Walzer:  He was a very complicated philosopher. He wrote a book about the moral sentiments, which is a wonderful book, and “The Wealth of Nations” is a wonderful book. No, I don’t think he’s wrong. In fact, I suspect that a close reading of his book would suggest that you can’t take, that he didn’t take the invisible hand as some kind of magic mechanism. He thought you did need some regulation of the markets to make it… to make, first of all, certainly you needed the police, you needed to control fraud, you needed to protect consumers against fraudulent behavior , and you needed to protect the competitors against various kinds of illegal uses of force or deceit. But, I think, probably you need a stronger state than he contemplated once you have a full-fledged corporate capitalist system.
