The book presents a comprehensive case for optimism in the modern era, arguing that humanity has made significant progress in various aspects such as health, prosperity, safety, peace, knowledge, and happiness, largely due to the values of the Enlightenment—reason, science, humanism, and progress. The author challenges the pervasive sense of pessimism in contemporary discourse and defends the scientific mindset and rational thinking as the driving forces behind improvements in human well-being. By analyzing a wealth of data and trends, the book encourages readers to appreciate the progress achieved and to continue embracing the Enlightenment principles to address current challenges and further advance the human condition.
