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

In cloning, in contrast, reproduction is asexual - the cloned child is the product not of two but of one.

As bad as it might be to destroy a creature made in God's image, it might be very much worse to be creating them after images of one's own.

Human life without death would be something other than human; consciousness of mortality gives rise to out deepest longings and greatest accomplishments.

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

I have nothing against respecting people who lived before, but we have no responsibility toward them.

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.
