I am trying to get at the moral arguments and the ethical status of various attempts at enhancement, or genetic engineering, or the bid for designer children. But there are implications for society at large.

Over the past three decades, markets and market thinking have been reaching into spheres of life traditionally governed by non-market norms. As a result, we've drifted from having a market economy to becoming a market society.

If parents are aiming at choosing children who will be good athletes, or great musicians, or who will get into Ivy League schools, or who will be tall enough to make the basketball team, then there is a danger that the life of the child will bear the burden of that expectation; and the risk of disappointment and the cost of disappointment will be even higher than they are now, and even now they can be considerable.

I'm a supporter of embryonic stem cell research. I do think there are very important moral and also religious questions at stake in the debate over embryonic stem cell research.

I think it would be a great tragedy to devote medical resources and genetic technological breakthroughs to purposes that are not to do with health or medicine, but instead are to do with satisfying the desires that are created by the consumer society.

The most fateful change that unfolded during the past three decades was not an increase in greed. It was the expansion of markets, and of market values, into spheres of life where they don’t belong.

If you go back to Adam Smith, you find the idea that markets and market forces operate as an invisible hand. This is the traditional laissez-faire market idea. But today, when economics is increasingly defined as the science of incentive, it becomes clear that the use of incentives involves quite active intervention, either by an economist or a policy maker, in using financial inducements to motivate behavior. In fact, so much though that we now almost take for granted that incentives are central to the subject of economics.
