Book I'm Reading: "21 Lessons for the 21st Century" by Yuval Noah Harari

The people we fight most often are our own family members. Identity is defined by conflicts and dilemmas more than by agreement.

Moreover, it is exceedingly dangerous to assume that a new world war is inevitable. That would be a self-fulfilling prophecy.

That guarantees the eruption of war.
