Should or shouldn’t Christians endorse the transhumanist agenda of changing human nature in ways fitting to one’s needs? To answer this question, we first have to be clear on what precisely the thesis of transhumanism entails that we are going to evaluate. Once this point is clarified, I argue that Christians can in principle fully endorse the transhumanist agenda because there is nothing in Christian faith that is in contradiction to it. In fact, given certain plausible moral assumptions, Christians should (...) endorse a moderate enhancement of human nature. I end with a brief case study that analyses the theological implications of the idea of immortal Christian cyborgs. I argue that the existence of Christian cyborgs who know no natural death has no impact on the Christian hope of immortality in the presence of God. (shrink)
