They wish to investigate, say, the problem of birth-control; what do they do?
The problems of eugenics and of birth-control affect us all.
Of such sort are the majority of inflammatory suffragettes of the sex-hygiene and birth-control species.
It is needless to insist how intimately that secondary end of marriage is bound up with the practice of birth-control.
Birth-control is effecting, and promising to effect, many functions in our social life.
That is a great truth which goes to the heart of the whole complex problem of eugenics and birth-control.
That is to say that the only instrument by which eugenics can be made practically effective in the modern world is birth-control.
For my own part, I scarcely consider that either eugenics or birth-control can be regarded as properly a part of religion.
And it is true that eugenics alone, like birth-control alone, can effect little if the economic basis of society is unsound.
It is a task inextricably bound up with the task of moulding the human race for which birth-control is the elected instrument.
