Editor's Take:

Kant spent his entire life in and around the Prussian city of Königsberg, yet his ideas travelled further than almost any philosopher's. His great question was how we can know anything at all, and his answer was that the mind actively shapes the way we experience the world. In ethics he argued that we should act only in ways we would be happy for everyone to follow, a principle still debated in moral philosophy. He also wrote about lasting peace between nations, ideas that later echoed in the founding of international organisations. Reading him is famously hard work, but modern philosophy is unimaginable without him.
