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.

QuestionWhy can’t we understand the basis of consciousness?

Richard Dawkins: Well, both what it is -- it clearly has something to do with brains, and it's something that emerges from brains. When brains get sufficiently big, presumably, as human brains have, consciousness seems to emerge. As to what it is, that's a philosophically very difficult question, which biologists are no more equipped to deal with than anybody else. 

QuestionIs there a certain brain capacity necessary for the development of consciousness?

Richard Dawkins: Oh, nobody knows, because we don't know which animals are conscious. We don't actually, technically, even know that any other human being is conscious. We just each of us know that we ourselves are conscious. We infer on pretty good grounds that other people are conscious, and it's the same sort of grounds that lead us to infer that probably chimpanzees are conscious and probably dogs are conscious. But when we come to something like earthworms and snails, it's anybody's guess.

Question: How can science have a unique insight into cognizance?

Richard Dawkins: Well, that's a very difficult question since we can't actually measure whether creatures are conscious. So I guess science has as much insight as any other subject, but I don't think I can answer that question directly. Maybe computer science has as much insight into it as any other science.
