Why read non-fiction? Is it just to find things out? Or is it for pleasure, challenge, adventure, meaning? Here, in seventy new pieces, some of the most original writers and thinkers of our time give their answers.

From Hilton Als on reading as writing's dearest companion to Nicci Gerrard on reading for her life; from Malcolm Gladwell on entering the minds of others to Michael Lewis on books as secret discoveries; and from Lea Ypi on the search for freedom to Slavoj Zizek on violent readings, each offers their own surprising perspective on the simple act of turning a page. The result is a celebration of seeing the world in new ways - and of having our minds changed.
