One could look over the past century and ask oneself, has the increased longevity been good, bad or indifferent?

Is it possible to covet a much longer life for one's self and be as devoted to the well-being of the next generation? It's a long argument.

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

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

We are somehow natured, not just to reproduce, but for sociality and even for culture.

Once you put human life in human hands, you have started on a slippery slope that knows no boundaries.

There's an ancient tension between wanting to savor the world as it is and wanting to improve on the world as given.
