Continue to read book "Sapiens: A Brief History of Humankind" by Yuval Noah Harari
Harari does not distinguish between his opinion and facts, nor explain the background of how he arrived at the theory of inter-subjectivity. The study of the evolution of cooperation is a hot topic, with political scientists, biologists, mathematicians and even physicists all having theories, and much data collected and many math models developed. It is apparent Harari is aware of this, but does not tell us how his theory fits in. I can only conclude he finds his powers of popular persuasion greater than his powers of scientific persuasion and critical analysis, so he writes a long book instead of a focused research paper.
Near the end Harari reports on happiness research. In this section of the book he takes exception to his usual approach, giving us descriptions of studies and names of researchers so we can trace where these conclusions come from. The book is worth reading for this section.
Occasionally Harari gets facts wrong. You won't realize this unless you have investigated the matter separately. I noticed it because his description of the origin of the caste system in India was wrong, according to current research.
Harari tries to present himself as outside modern factions (or inter-subjective realities), such as nature vs. nurture, liberalism vs. conservatism, etc. But without conscious explication, he suffuses his book with the assumption that any modern human if taken from birth is equally at home in any of the current or historical inter-subjective realities. He does not propose or even consider experiments to determine culture-vs-genetics. So he proposes this important genetic ability evolved in a small population on a single continent between 130kya and 70kya, but that no differentiating evolution has occurred since then.
The question of whether the degree or style of inter-subjectivity is as universal as he implies is important for several reasons. Harari proposes the world is "different" since 1945, with no war between major powers, no more empires expanding by territorial acquisition. He suggests some reasons for this (cost of nuclear war, for example) which are unverified. His book was completed in 2014 before Russia claimed parts of Ukraine and China claimed the entire South China Sea. If inter-subjective capacity is universal, then this situation is likely unstable. People could quit believing it at any moment, and the world could return to any state that it has been in historically. If inter-subjective capacity is not identical in everyone, then it might make a great deal of difference which cultures dominate, even if through historical accident. See for example Boyd and Richerson 2009 Culture and the Evolution of Human Cooperation.
