”Merely fact-minded sciences make merely factminded people.”“ …the positivistic concept of science in our time is, historically speaking, a residual concept. It has dropped all the questions which had been considered under the now narrower, now broader concepts of metaphysics….all these ‘metaphysical’ questions, taken broadly – commonly called specifically philosophical questions – surpass the world understood as the universe of mere facts. They surpass it precisely as being questions with the idea of reason in mind. And they all claim a (...) higher dignity than questions of fact, which are subordinated to them even in the order of inquiry. Positivism, in a manner of speaking, decapitates philosophy.”Edmund HusserlIn ethical literature associated with controversies at the beginning and end of human life, there is often a two-part structure: first, basic facts about the topic are presented in a more or less descriptive format, then there is the ethics or policy.

The ethical issues integral to embryo research and brain death are intertwined with comprehensive views of life that are not explicitly discussed in most policy debate. I consider three representative views – a naturalist, romantic, and theist – and show how these might inform the way practical ethical issues are addressed. I then consider in detail one influential argument in embryo research that attempts to bypass deep values. I show that this twinning argument is deeply flawed. It presupposes naturalist commitments (...) that are at issue in the embryo research debate, and exhibits a blindness to alternative philosophical viewpoints. By considering the work of Hans Driesch, the discoverer of the facts of embryology integral to the twinning argument, I show how the twinning facts are compatible with romantic and theistic accounts that affirm full moral status for the early embryo. While these alternative interpretations might have a tenuous status in current scientific debate, they should be respected in ethical and policy debate. (shrink)
