21 Lessons for the 21st Century

Yuval Noah Harari

Recommended by 2 people on the record.

The bar next to each date shows how long ago it was said: 6d is days, 4yr is years.

Rakhim Davletkaliyev loved it
A very well written bird’s eye view of the humanity landscape. Empathetic and neutral at the same time. I want to Yuval’s other books now.

That little bar

It says how long ago something was said, so you can tell last month from 2014 without doing the arithmetic. Full and green is recent; it drains and cools as the date gets older, and empties completely at about 6 years.

A striped bar means the date itself is an estimate — the source did not carry an exact one. An entry with no date at all gets no bar.
