Transhumanism is a blanket term given to the school of thought that refuses to accept traditional human limitations such as death, disease and other biological frailties.
Dr McNamee said transhumans are typically interested in a variety of futurist topics, including space migration, mind uploading, cryonic suspension and more current subjects like nanotechnology, computers and neurology.
He said, "Of the many points that may be said in favour of TH, I note three.
"The use of technology to improve the lot of humans is something we pretty much take for granted. Much good has been achieved with low-level technology in the promotion of public health.
"Second, proponents of TH say it presents an opportunity to plan the future development of human beings, the species homo sapiens, instead of this being left to the evolutionary process and its exploitation of random mutations.
"Third, the view that moral status is independent of membership of a particular species (or indeed any biological species), TH presents a way in which moral status can be shown to be bound to intellectual qualities."
He admitted there were critics of TH who feared it could lead to the existence of two types of being.
