Bioethics Today

At the Center for Inquiry's Point of Inquiry blog, Chris Mooney speaks with bioethicist Art Caplan about the state of bioethics today, and how the most pressing issues in the field have changed during the past several years. Where the Bush administration was "too philosophical" in its application of bioethics over issues like stem cells and cloning, the Obama administration has done a "full 180" and is "more policy oriented" when it comes to legislating ethically tricky issues, Caplan says. Now the problem is access to health care, he adds.
