 While many ethical systems place a primary moral value on preserving and protecting nature and the natural given world, transhumanists do not see any intrinsic value in defining what is natural and what is not and consider arguments to preserve some perceived natural state of the human body as an unjustifiable obstacle to progress. Not all philosophers are critical of transhumanism, as an example Nick Bostrom (2008) of the Future of Humanity Institute at Oxford University argues that putting aside the feasibility argument, we must conclude that there are forms of posthumanism that would lead to long and worthwhile lives and that it would be overall a very good thing for humans to become posthuman if it is at all possible (Bostrom, 2008).
