“The Virtual body is a body of great potential. On this body we can reinscribe ourselves using whatever coding system we desire. We can try on new body configurations. We can experiment with immortality by going places and doing things that would be impossible in the physical world. For the virtual body, nothing is fixed and everything is possible. Indeed, this is the reason why hackers wish to become disembodied consciousness flowing freely through cyberspace, willing the idea of their own bodies and environments.” Flesh Machine: Critical Art Ensemble 1998.
If you've not read the book Flesh Machine you can download it for free from the Critical Art Ensemble's website. It's definitely a must if you're interested in Cyborg/Posthuman theory (along with other issues such as Eugenics, Pancapitalisn, and the Net)
