positive eugenics is the science of race building through wise mating.
This, in brief, is the problem of Negative and of positive eugenics.
The problem of positive eugenics presents an essentially different aspect.
positive eugenics represents the attempt to encourage breeding from every healthy stock.
Negative Eugenics eliminates the unfit; positive eugenics perpetuates the fit.
Negative eugenics tends to be ahead of positive eugenics; it is easier to detect bad stocks than to be quite sure of good stocks.
positive eugenics may be as obvious as Negative Eugenics, but the promulgation of its doctrines is not equally easy.

The investigation of human eugenics, that is, of the conditions under which men of a high type are produced. [Galton, "Human Faculty," 1883]
