Global Thinking: The Smartest Way to Think

What is global thinking? How does it differ from narrow framing, and why does it help in decision-making?

Homo Sapiens History: From Early Man to Modern Industry

In Sapiens, Yuval Noah Harari uses concepts from physics, chemistry, biology, and history to tell the story of us, Homo sapiens history. Homo Sapiens history is punctuated by four major revolutions: The Cognitive Revolution, the Agricultural Revolution, the Scientific Revolution, and the Industrial Revolution. Each revolution ushered in a new era of innovation (and, often, suffering) for humans. In this brief history of Homo sapiens, we’ll look at each revolution and how it dramatically redirected the course of the history of Sapiens.
