Here's the abstract in its current incarnation (feedback welcome):
As the potential for enhancement technologies migrates from the theoretical to the practical, a difficult and important decision will be imposed upon human civilization, namely the issue as to whether or not we are morally obligated to biologically enhance nonhuman animals and integrate them into human and posthuman society. Precedents for intra-species cultural uplift abound in human history, providing both sobering and edifying episodes showcasing the possibilities for the instigated and accelerated advancement of technologically delayed societies. As a number of scientists, philosophers and futurists have recently argued, there is mounting evidence in support of the suggestion that these historical episodes are symptomatic of a larger developmental trend, namely the inexorable and steady advancement of intelligence. Civilizational progress necessarily implies increasing levels of organization and refinement across all realms of activity. Consequently, the status of nonhuman species and the biosphere will eventually come under the purview of guided intelligence rather than autonomous processes. That said, a developmental tendency towards uplift does not imply that it is good or right; more properly, it can be argued that uplift scenarios do in fact carry moral currency. Through the application of Rawlsian moral frameworks, and in consideration of the acknowledgement of legally recognized nonhuman persons, it can be shown that the existence of uplift biotechnologies will represent a new primary good and will thus necessitate the inclusion of highly sapient nonhumans into what has traditionally been regarded as human society. In addition to issues of distributive justice, the Rawlsian notion of original position can be used to answer the question of whether or not there is consent to uplift. Finally, it will be shown that the presence of uplift biotechnologies in the absence of the legal recognition of nonhuman persons and a mandate for responsible uplifting will ultimately lead to abuse, adding another important consideration to the uplift imperative.
