Julian Baggini's book "How the World Thinks: A Global History of Philosophy" provides a comprehensive account of philosophical traditions from antiquity to the present, from ancient Greece to contemporary China. Baggini examines the major theories and thinkers who have influenced how we perceive reality, our place in the world, and ourselves by drawing on a variety of sources and viewpoints. Together with the well-known Western philosophical canon, the book analyses a wide range of philosophical traditions, such as Indian, Chinese, African, and Islamic philosophy. Baggini's research demonstrates how several philosophical traditions can confront and support one another, providing a rich and complex understanding of human cognition and culture.
