バートランド・ラッセル英熟語 a051
★ at will [意のままに,自分の思うままに]
The study of heredity may in time make eugenics an exact science, and perhaps we shall in a later age be able to determine at will the sex of our children. This would probably lead to an excess of males, involving a complete change in family institutions.
* eugenics : 優生学
[遺伝研究は,やがては優生学を精密科学に成長させ,恐らく,後世,我々は,意のままに,生まれてくる子供の性(男女の別)を決定できるようになるかも知れない。このことは,多分,男性の数を(女性より)過度にさせ,家族制度に根本的な変化が伴うであろう。
