LITERARY agent and provocateur John Brockman has turned popular science into a sort of modern shamanism, packaged non-fiction into gobbets of smart thinking, made stars of unlikely writers and continues to direct, deepen and contribute to some of the most hotly contested conversations in civic life.

This Idea Is Brilliant is the latest of Brockman’s annual anthologies drawn from edge.org, his website and shop window. It is one of the stronger books in the series. It is also one of the more troubling, addressing, informing and entertaining a public that has recently become extraordinarily confused about truth and falsehood, fact and knowledge.

Edge.org’s purpose has always been to collide scientists, business people and public intellectuals in fruitful ways. This year, the mix in the anthology leans towards the cognitive sciences, philosophy and the “freakonomic” end of the non-fiction bookshelf. It is a good time to return to basics: to ask how we know what we know, what role rationality plays in knowing, what tech does to help and hinder that knowing, and, frankly, whether in our hunger to democratise knowledge we have built a primrose-lined digital path straight to post-truth perdition. . . .
