Intelligence has a pretty well established definition, the one you quote is fine, "the ability to acquire and apply knowledge and skills." I would say that, if one is really intelligent, one acquires and applies knowledge of oneself and the skills to change habits and behaviours. That's the "self-referential" stage of intelligence. Wisdom, on the other hand, is much harder to define. The definition you quoted is circular, as are almost all dictionary definitions of "wisdom". I've heard it said "A fool never learns, a man learns from his mistakes, the wise man learns from the mistakes of others." Some would say that wisdom comes from loving God and loving your neighbor as yourself. You say that they are different and that I'm "confusing intelligence with wisdom", but I say that wisdom and intelligence are on the same spectrum or continuum, that the former is the refinement and maturity of the latter. In any event, my original point is that proponents of eugenics are not as intelligent as they think they are.
