Ok, so I got to the end of the F.B. Meyer book. (I’m not a minister, so I don’t spend all my time in my study reading books ).
First off, the paraphrase about F.B. Meyer’s statement is misleading. As a reminder, this book said:
“…the influential Protestant minister F. B. Meyer, author of Religion and Race-Regeneration (1912), warned that the high birthrates of Catholics, Jews, and the feebleminded presented a collective menace to society.”
And this book was referenced as the source.
Well, it turns out that Meyer was actually comparing the consistent birth rate of Catholics, Jews and the feebleminded and casual labourers and clergy (of which he was one), with the decreasing birthrate of the higher classes. He did this to demonstrate that the decreasing birthrate is not due to a natural decline of national fertility, but due to personal choice, including the use of contraceptives.
A disappointing misrepresentation.
However…as you have said, Joseph, F. B. Meyer was a Eugenicist, though of a more Christian flavour. In fact, the beginning of the book lists him as Chairman of the National Council of Public Morals for Great and Greater Britain, a Christian based organisation committed to the regeneration of the British ‘race’.
These are my observations about F. B. Meyer’s take on the issue:
Meyer believed that Britain was well-placed to bring about a new era of Christian paradise - even the new heavens and new earth - through the regeneration of the race.
Science, religion, education and other disciplines can work together to do this, but only religion can provide the necessary motivation to see it through.
Feeblemindedness is seen primarily in terms of laziness, immorality and lack of character.
It is not only about genetics, but largely about the environment of a good home. That is, a home can be converted to produce strong citizens, and individuals can be converted or reformed. As a fruitful evangelist, Meyer saw this as part of the solution, and seemed to believe this should lead to producing a nation of worthy families - I guess where Christians were made in the home.
He does not speak of preventing unsuitable marriages and child-bearing through force, but would encourage people who recognise they have conditions like epilepsy, feeblemindedness, hereditary health problems, etc, to voluntarily avoid marriage so as not to pass their troubles onto their innocent children.
I do not believe he fits the contemporary caricature of a eugenicist - he would deplore the murderous, manipulative and malevolent movement seen in Hitler’s dreams - but he does incorporate the above form of deliberate breeding (in my point no.5) into his strategy for bringing about God’s Kingdom through Britain.
