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.

The Big Idea for Tuesday, February 14, 2012

Love is extraordinarily difficult to talk about, because the word recedes into meaninglessness as you try to track down its various real-world correlates and articulate what connects them. The last people to attempt it seriously may have been the ancient Greeks, who distinguished between Eros (passionate, intense desire), Philia (affinity – a strong feeling of friendship, brotherhood, or sisterhood), and Agape (love for God, love for all humanity). 

In its many forms, love is a powerful engine of human activity, yet we struggle to understand how it operates – what facilitates love in its various forms and what hinders it.
