"Contributions to the volume expose and challenge a number of assumptions in unpacking and interrogating the notion of enhancement. ... those interested in the direction of theory and debate about notions of enhancement, the animal question ... and broader societal implications will find contributions in this volume to be useful. ... This volume provides an interesting contribution to what will continue to be a substantive debate." (Colin Salter, Nanoethics, Vol. 10, 2016)
