But this is not due to some chauvanist agenda anymore than a peacock's tail feathers are.

<br>But I suspect that an evolutionary handicap principle might in fact exist. See for instance the exhibition of obviously uselessly dangerous behaviour ("Look, possible sexual mate, if I am ethologically inclined to embark in such futile daring, and yet my genes are still around, they must otherwise be really, really good").<br>
<br>This, of course, need not go away in a posthuman-but-still-biological context. Things would of course be made more complicate by the fact at each generation our genetic endowment can be modified. Yet, the direction in which it is will in turn depend on one's "nature" and preferences, something which is in turn at least to some extent programmed by our existing genetic endowment.<br>
