This is the message as the crawl holds it, before anything
here touched it. What the conversation shows has been through ingest: transfer
encodings decoded, attachments dropped, quote markers repaired, and the
archiver’s ? resolved into quotation marks and dashes. Those
repairs are judgements and some of them are wrong, which is what this page is
for. Email addresses are obscured here as they are everywhere else on the site,
so it is before our repairs rather than byte for byte.

No, this is not correct.

I presume you are thinking about humans here. There is plenty of evidence of epigenetic inheritance, including transmission of behaviours, in other species. Furthermore, the mechanisms, eg genetic imprinting, are well understood mechanistically (sections of DNA are marked by addition of methyl groups to cytosines). > The way one feels toward evolutionary psychology (and related > doctrines) tends to have more to do with how one feels about a range of > philosophical issues, from one's stance on the mind, to the metaphysics > of souls, to base factionalism.

I think Wolfe has thought deeply about this, starting from _tFHoC_, _tDoDI_, to the chems, possession, and Horn-Pas-Silk. Specifically, the chems have souls and an interest in right thought and action, but their *minds* can be completely controlled by others, and they are aware of this. For "ordinary" humans, their actions are just as frequently controlled by society and exigency, even if they have more freedom of thought, so that practically they end up in the same boat. Many of his characters do as much good as they can within strong constraints. Those constraints can easily be genetic predispositions to particular behaviours. Further, staying on Wolfe, he definitely believes in human nature, and that this will persist indefinitely, and will be seen in other species or in robots. A la Lem, you will know when you have a true artificial intelligence when it demonstrates laziness, duplicity, self interest, and a tendency to do other things, such as contributing to news groups, when it should be working.
