The academy is in crisis. Students call for speakers to be banned, books to be slapped with trigger warnings and university to be a Safe Space, free of offensive words or upsetting ideas. But as tempting as it is to write off intolerant students as a generational blip, or a science experiment gone wrong, they’ve been getting their ideas from somewhere. Bringing together leading journalists, academics and agitators from the US and UK, Unsafe Space is a wake-up call. From the war on lad culture to the clampdown on climate sceptics, we need to resist all attempts to curtail free speech on campus. But society also needs to take a long, hard look at itself. Our inability to stick up for our founding, liberal values, to insist that the free exchange of ideas should always be a risky business, has eroded free speech from within.
