First, check out the Wikipedia entry on biological uplift (although this entry could use a lot of work).
Second, there's my paper from a few years back, "All Together Now: Developmental and ethical considerations for biologically uplifting nonhuman animals." My basic argument is that we should strongly consider the inclusion of nonhuman animals into postbiological space. The more the merrier, I say.
Third, be sure to check out (or review) David's seminal work on the matter from a fictional perspective, namely his Uplift Series. Books in this collection include:
- Sundiver (1980)
- Startide Rising (1983)
- The Uplift War (1987)
- The Uplift Storm Trilogy
Lastly, check out some of the work done by Sue Savage-Rumbaugh and the Great Ape Trust. Just to be clear, Sue is not an advocate of biological uplift, but the work that she does integrating bonobos into non-traditional living environments and in comprehending their language and culture speaks directly to this issue; there's a very fine line between cultural and biological uplift. For starters, check out the article, "Sue Savage-Rumbaugh on the welfare of apes in captivity." Also be sure to check out the work of the Great Ape Trust.
And while we're on this topic: please support the work done by the Great Ape Project and advocate for the inclusion of great apes into the personhood spectrum.
