I tried top read online this trash-book, here in Brazil. This book was writen by Sir Charles Galton Darwin (1887-1962), a grandson of Charles Darwin. And such as Charles Darwin, he was an eugenist.
And this book was writen in 1950 decade, when the eugenists became claiming that they were now under then new titles of "malthusianists" or "neo-malthusianists". This trash-book is divided into eleven parts. The first is the introduction and the last is the epilogue. Second part has as title "population". The third part has as title "The four revolutions".
The introduction is a strange misture of nothing with value, lies and believes.
In the chapter about population, page 37, the author follows the same weird believes preached today by Greepeace and WWF. He is cleary against the improvements of live of persons, by a construction of a dam in India.
Even, when it anything with value, there's flaws.
One example is when he talks, about celibacy in Catholic Church. Repeating decades old eugenics' arguments against celibacy, while he forgest that European Catholic countries became far better than China, that had a system with his admiration.
The chapter about limitation of populations, he claims sterilizations for Malthusian reazons, while remembering eugenics. In fact,the author was a knowed eugenist. Malthusian lies are spread in all this book. The author also tells dozens of agronomical lies, repeated today by mafias such as Greepeace.
The last chapter is the epilogue and is even worse that the chapters. The author is pessimistic and wrong, about the world's future.
