Utopian ideologies of the last century rejected traditional faiths and claimed to be based in science. They were actually secular versions of the myth of Apocalypse - the belief in a world-changing event that brings history, with all its condlicts, to an end. This text argues that the death of Utopia does not mean peace.
The book is well-argued, though it becomes one-sided at certain points due to an overly polemical orientation. Another minor criticism is that the chapter on the American wars of the 2000s and the misinformation strategies feels a bit out of place in the book.
In any case, I find much of what Gray writes to be convincing, in spite of my wish at certain points to disbelieve him. Nevertheless, Gray's underlying skepticism of our capacity to A) change things for the better, and B) live at least MORE if not TOTALLY satisfying societies is, I think, ultimately over-stated. Given that these are the main undercurrents of the book, I suppose that I take what Gray writes to heart, but am not totally persuaded.
