Langan's Cognitive Theoretic Model of the Universe is a high-level cosmological vision that is the very opposite of materialism. I did a thread describing the CTMU here on the forum, which should come up if you search for it. There is quite a bit of overlap with the cosmology described by the C's. The main difference is that Langan's CTMU is mathematically grounded.
Langan's position on eugenics favors what you might call positive eugenics - incentivizing greater reproduction amongst the smartest and strongest of humanity while encouraging people to reproduce at a responsible level so as to simultaneously gradually improve genetic quality (or simply avoid degradation) while avoiding overcrowding. Note that IQ has been declining quite rapidly in the Western world in recent decades.
His main point of disagreement with the parasite class is that the latter seem intent on dysgenics: turning humanity into a dumbed-down, cyborg slave species. He also strongly opposes centralized, top-down control, of reproduction or anything else. So, rather than something like reproductive licensing boards, think of something more like a general culture that encourages people of high quality to have kids, while discouraging those of low quality. My impression is that he has something much more akin to the eugenic culture of classical Greece, rather than the bureaucracy of Nazi Germany.
Frankly, were it not for the heavy hand of the state creating deliberately perverse incentives, redistributing resources from the capable to the incapable, making family formation almost impossible for high-functioning people, etc., I suspect eugenic breeding would happen quite naturally.
