A Response to Ian Linden.

The article discusses the book "A New Map of the World," by Ian Linden. Linden has already moved on since writing the book, and if the book has emphases and approaches in it that are not mine, the development the paper seems to show brings people into almost complete agreement. Linden now, for example, draws into the analysis the enormously significant cases of India and China, which together make up about 40% of the world's population. Nor does he now lay so much emphasis on the Asian collapses of 1978.
