Is childhood something that we can leave behind, or indeed should? In their latest article for Think, Emma Swinn and Steven Campbell-Harris challenge the conventional understanding of children and adults, revealing how these rigid categories create problems in our education system, democracies and personal lives. Through the revolutionary education movement ‘Philosophy for children’ (P4C), they explore how retaining the ‘childlike’ qualities of questioning, playing and embracing uncertainty can transform our approach to learning and paradoxically help us to live more fulfilled adult lives.
