Sapiens: A Brief History of Humankind

I feel like this book should be a required reading for every high school student – it humbles readers by presenting a captivating summary of the origins of our own species, explores how society has changed and evolved throughout millennia, and provides some excellent food for thought regarding the origins of readers' own beliefs and the many social constructs, from human rights to religion to economics, that are widely ingrained in our collective culture.

Definitely my new favorite book, rivaling the Design of Everyday Things, Garbology, and Creativity Inc.
