We seem to be miscommunicating, because I think you understand my point, but think that I don't, and are trying to communicate to me the same thing that I was trying to communicate to you.
To be more clear, then: When I talked about consistent with, what I really mean is probably compatible with. A hammer doesn't logically preclude the existence of tables. A definition of eugenics that is incompatible with the other things we know about evolutionary biology is a poor definition. There are things we know about how environments interact with genes, and if a definition of eugenics is incompatible with those known facts, then it's a useless definition.
Sure, a definition needs to be self-consistent as well as generally consistent (comparable with the other things we know about evolutionary biology) in order to be useful. Again, I take that simply as a given. As such, when one speaks of being consistent with a definition I generally take that to mean, whatever is being discussed, conforms to that definition. Hence, my question of incorporating the difference mentioned in the definition.
To take it back: you talked about a definition of eugenics in which the goal was some sort of perfect human, and that perfection was based not on genes, but outcome (for instance, being control of the breeding process).
No, specifically a genetically perfect human. As such "that perfection was based" primarily and specifically on genetics. Also note that I don't subscribe to the notion of there even being a genetically perfect human. Hence, by that definition eugenics is generally inconsistent.
How do you gauge the success of any such selective breeding program without the outcome of the genetics combined with the environment?
Let's say you're breeding for long legs and you get offspring with long legs. However, those longer legs can't support the body under normal environmental stresses. Is that a selective breeding success or not? Again it comes back to what the intent of the breeding program was. If it was just for long legs to get say more leg meat, longer bones or other aspects not related to the practical functioning of the legs. Then sure that would be a success.
But that outcome is just as influenced by environmental factors that are outside of the control of the genes as it is by anything else.
That's the sociological aspect and intent of eugenics as repeatably noted by, I think,Cavemonster. As the genetics change so too does that sociological environment.
Again with people as the subject of the selective breeding as well as in control of it, the changes in genetics also influence the environment. Both as the rearing and development environment I've mentioned before but also just the type of environment such beings would live in.
Certainly aspects of environment are outside of human control. However, one of the things that makes us successful as a species is our ability to adapt to differing environments. Both by controlling the environment where we can or mitigating its adverse effects on us where we can't exercise control.
Now certainly selective breeding can produce people better suited to a particular environment but that of course tends to leave them more vulnerable in other environments.
If someone were designing a program to breed the perfect or best human, those environmental factors would not be a useful thing to take into consideration because their breeding program only affects genes, not those environmental factors.
Does that make sense?
Sure it did, but that's why I gave the chicken example before where the genetics of the chicken bred for fast growth and big muscles was incompatible with the normal chicken mating environment. In order to continue to breed that type of chicken that environment would have to change. Where I used artificial insemination as an example of such a change.
I think you are still thinking of this in terms of one population selectively breeding another, even as both being humans. Where the etymological and historical context of eugenics has been selective breeding of people by those people and specifically for obtaining the 'best born' of those people. Sort of like the idea of being noble born before. As such the breeding population would inherently be the controlling population as well, including as much control of the environment as humanly possible.
