It is, however, a phase of euthenics, which deals with the environmental factors that affect the individual life.
euthenics precedes eugenics, developing better men now, and thus inevitably creating a better race of men in the future.
euthenics is the term proposed for the preliminary science on which Eugenics must be based.
In another hundred years, then, euthenics may give place to Eugenics, and the better race of men become an actuality.
In this sense, euthenics and eugenics bear the same relation to human progress as a man's two legs do to his locomotion.
The moment of conception is the point at which eugenics gives place to euthenics.
