Even More.....

Steve Chapman lays out the stem-cell debate further.

Harold Varmus, co-chairman of the president's scientific advisory council,
said it showed the president would rely on "sound scientific practice ...
instead of dogma in developing federal policy." But one person's dogma is
another one's ethical imperative or moral principle. Science can tell us
how to build a nuclear weapon. But science can't tell us whether we should use it. Just because research may be useful in combating disease doesn't
mean it's ethically acceptable. The infamous Tuskegee syphilis experiment -- in
which the federal Public Health Service secretly withheld treatment from
infected black men to learn more about the disease -- might have yielded
valuable data. But no scientific discovery could possibly have justified
it. [emphasis mine]

That's precisely what I say here and here.
