Abstract
Steven Pinker's book Enlightenment NOW is in many ways a terrific book, from which I have learnt much. But it is also deeply flawed. Science and reason are at the heart of the book, but the conceptions that Steven Pinker defends are damagingly irrational. And these defective conceptions of science and reason, as a result of being associated with the Enlightenment Programme for the past two or three centuries, have been responsible, in part, for the genesis of the global problems we now suffer from, and our current inability to deal with them properly. There is not a glimmering of an awareness of any of this in Pinker’s book. This flaw in Enlightenment NOW is serious indeed.
