"It is easy to take umbrage at Mr. Ponnuru's blunt and sometimes inflammatory rhetoric, but it is hard to read his survey of the controversies in bioethics today without shuddering at the outer limits of what is now permissible under law. And it is hard not to worry about the coarsening of our moral sensibilities and fear for a more permissible future....But bright lines do not always exist--in law, ethics or politics. That doesn't mean that lines cannot be drawn; they can indeed, carefully, responsibly and defensibly. But they may be neither brightly obvious nor rigidly predictable. They may even shift over time, affected by the kind of debate to which Mr. Ponnuru has made such a forceful contribution."Ponnuru, Ramesh is the author of 'Party of Death The Democrats, the Media, the Courts, and the Disregard for Human Life', published 2006 under ISBN 9781596980044 and ISBN 1596980044.
