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.

Your Brain is God: Religion in the 21st Century

What's the Latest Development?

Oliver Sacks, the popular author and professor of neuroscience at NYU, claims that the brain alone is sufficient to provide for the kinds of religious experience that have convinced several neuroscientists, presumably skeptical of metaphysical forces, that God and heaven do exist. The dark tunnel often described by people who have near-death experiences can be explained by the constriction of the visual field due to compromised blood pressure in the eyes. And the bright light at the end of the tunnel represents a flow of visual excitation from the brainstem to the visual cortext. 

What's the Big Idea?

Sacks does not deny that the experience of higher realms of existence can play a part in spiritual life or even have great meaning for an individual, but the roots of the experience, he insists, remain terrestrial: "The tendency to spiritual feeling and religious belief lies deep in human nature and seems to have its own neurological basis, though it may be very strong in some people and less developed in others. ... [H]allucinations cannot provide evidence for the existence of any metaphysical beings or places. They provide evidence only of the brain's power to create them."
