My job is to provide the president with the richest possible consideration, so that he knows what is at stake in whatever decision he makes.

Cloning represents a very clear, powerful, and immediate example in which we are in danger of turning procreation into manufacture.

The benefits of biomedical progress are obvious, clear, and powerful. The hazards are much less well appreciated.

We know next to nothing of what we're going to know in 20 or 50 years.

Many other countries have already banned human cloning, and there are efforts at the UN to make such a ban universal.

I don't believe that efforts to prohibit only so-called reproductive cloning can be successful.
