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

In the case of abortion, one pits the life of the fetus against the interests of the pregnant woman.

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

The abortion controversy is important for what it says about our stance toward procreation and children altogether.

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.

Perhaps you could sympathize with those who seek to replace a dead child with a copy, or to copy a parent or a relative or even a celebrity.
