An exploration of some of the most important and enduring ideas in human history – from religion, science, philosophy, medicine, psychology, politics, economics and art – each presented in brief, accessible form.

They are the ideas that have had a huge impact on human civilization – and they come from all disciplines of human ingenuity.

Topics covered range widely and include Creation Mythology, Existentialism, The Elements, Relativity, Space Travel, Geometry, Ethics, Behaviourism, Genetics, Warfare, The Nation State, Anarchism, Capitalism, Classical Art and Architecture, The Renaissance – and much more.
