The use of fetuses as organ and tissue donors is a ticking time bomb of bioethics.

[Cloning] can't make you immortal because clearly the clone is a different person. If I take twins and shoot one of them, it will be faint consolation to the dead one that the other one is still running around, even though they are genetically identical. So the road to immortality is not through cloning.

The time to talk about it [genetic engineering to improve a baby's genes] in schools and churches and magazines and debate societies is now. If you wait, five years from now the gene doctor will be hanging out the MAKE A SMARTER BABY sign down the street.

The challenge is for bioethicists to position themselves to be on panels, boards and other decision making bodies where oublic policy positions wil be established-where the exploding changes in health care that are now underway will be addressed.

With terminal illness, your fate is sealed. Morally, we're more comfortable with a situation where you don't cause death, but you hasten it. We think that's a bright line. Comparing the U.S. with Switzerland, where assisted suicide is legal for patients suffering 'intolerable health problems.'

Bodies aren't the same as Coca-Cola cans.

There has never been just 'coach class' health care, but with these amenities you are seeing people get priorities according to your ability to pay. It's one thing to say you get perks; it's another to say you can buy your way to the head of the line.
