Yuval Noah Harari is an Israeli historian and a tenured professor.He is the author of the international bestsellers Sapiens:A Brief History of Humankind(2014) and Homo Deus:A Brief History of Tomorrow(2015). His writings examine concepts of free will, consciousness and definitions of intelligence.
The book starts from the initial stages of revolution i.e cognitive revolution and takes us through agricultural revolution,unification of mankind and finally scientific revolution.The book briefly explains about how Homo sapiens has evolved from being a species of no significance to one of great significance(a god) and become a dominant creature in the world. They had become so dominant that they have become selfish and at the cost of lot of things. We have the cause of not only extinct of other human species such neanderthals, as well as other species of flora and fauna. We have create created the world with our vivid imagination, we created politics, caste,creed, religions and the society that we live in. He talks about that this were created out our imagination and hence fiction. He also talks about the rise agriculture ,trade and money and how their impact in our life. They discovery of money not only helps us out to run trade easy, but also helps us build trust among people. Money has become our lifeline and we have grown to anything around the currency we value it more than anything. At the end he concludes with talking of scientific revolution. Apart from Money, science has become part and parcel of life. They have brought in cure for various diseases , increases our life expectancy and thereby increasing the comfort level of life. The basis for the development of science and technology is that we accept that “We do not know the answer for a particular issue” or “there is a better solution”. We are always on look out for answers and not satisfied with what we have around us. He also says that another factor contributed to the scientific revolution-that being innovation brought in by the european elite despite being a small nation with dream of ruling the world. the author easing writes about the existing correlation between science,politics,economy and its impact on growth of nation.
With development of trade, money and scientific development, brought into existence different ideologies such as consumerism,nationalism, communalism, globalisation , liberalisation and thereby creating a complex ecosystem. They have brought the world more closer than ever like never before and it has had its own complication.
Thus concluding the review with a quote from the book:“Ever since the Cognitive Revolution, Sapiens have thus been living in a dual reality. On the one hand, the objective reality of rivers, trees and lions; and on the other hand, the imagined reality of gods, nations and corporations. As time went by, the imagined reality became ever more powerful, so that today the very survival of rivers, trees and lions depends on the grace of imagined entities such as the United States and Google.”
I would rate the 4.5/5 and the book is a good addition to my collection of books and a must read.
