Weapons of Reason magazine exists to turn knowledge into action. Each issue focuses on a big, difficult, important challenge facing the world and breaks it down into a collection of stories, illustrations and infographics that give an in-depth but accessible account of what’s happening. At the end of most stories you’ll find a ‘What now?’ section recommending practical next steps like further reading, a group you could join or a service you could try.

This eighth and final issue tackles the concept of war.

In this issue:

• War as a constant part of humanity’s story
• How images of heavily militarised policemen became ubiquitous in the media
• On the AK-47, the most popular weapon of the 20th century
