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

Genetics is crude, but neuroscience goes directly to work on the brain, and the mind follows.

The human animal has evolved as a preeminently social animal.

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

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

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

Biology, meaning the science of all life, is a late notion.
