Pinker, Steven  
  
  
    The follow-up to Pinker's groundbreaking "The Better Angels of Our Nature" presents the big picture of human progress: people are living longer
 healthier
 freer
 and happier lives
 and while our problems are formidable
 the solutions lie in the Enlightenment ideal of using reason and science. Far from being a naïve hope
 the Enlightenment
 we now know
 has worked. But more than ever
 it needs a vigorous defense. The Enlightenment project swims against currents of human nature--tribalism
 authoritarianism
 demonization
 magical thinking--which demagogues are all too willing to exploit. Many commentators
 committed to political
 religious
 or romantic ideologies
 fight a rearguard action against it. The result is a corrosive fatalism and a willingness to wreck the precious institutions of liberal democracy and global cooperation.
