In case you hadn't noticed, I recently added a link in the left-hand column to the BioEthics Defense Fund. Do go have a look at their website, and support them if you can. These kinds of issues are quickly becoming the leading edge of the moral battle in modern times, eclipsing things like sexual behavior, war, drugs, violence and political corruption.
The Blue Boar contributes a piece on the current Chinese practice of harvesting - and selling - the organs of executed political prisoners and other Enemies of the State.
These practices, like abortion, are outrages committed against human dignity, as if our humanistic modern world has ironically turned against human beings. Like so many humanitarians, they labor for the good of some abstract thing called "humanity", while counting individual humans to be of no inherent value.
So, one human is worthless, but a lot of us together are important, for some reason.
C.S. Lewis examines this in his prophetic little book, Men Without Chests;
First of all, he might say that the real value lay in the utility of such sacrifice to the community. 'Good', he might say, 'means what is useful to the community.' But of course the death of the community is not useful to the community—only the death of some of its members. What is really meant is that the death of some men is useful to other men. That is very true. But on what ground are some men being asked to die for the benefit of others?
Without a transcendent morality, it all comes down to power, sooner or later.
