"Against Perfection: The Just Battle between Technology and Humanity is Harvard professor Sandel's work after "Justice" and "What Money Can't Buy". It once again starts from social hot spots and inspires us to grasp real problems more deeply through rational thinking. In the book, the author keenly points out that the pursuit of perfection by human beings using high-tech means is becoming an increasingly fierce trend: parents will be able to freely customize the innate characteristics of their children in the genetic supermarket; athletes will be able to improve their performance on the field through genetic modification; students will be able to take memory pills instead of studying hard in the cold window... Will this bring about the liberation of individuals or the chaos of society? Sandel pointed out that mankind's pursuit of perfection through science and technology may seem like a mass carnival, but in fact it contains a deep crisis - the moral foundation that maintains human society is likely to collapse, and mankind's status in the universe will also be disrupted. Through clear arguments and concise language, we will gradually understand that behind the "anti-perfection" stance, the author has a deep thinking about man's place in the world and a deep concern for the fate of mankind.
