There's no necessary connection between maximizing social utility or economic wealth and creating a flourishing democracy. The first does not guarantee the second. The only way to create a flourishing democracy is to find ways to reason together about the big questions, including hard questions about justice and the common good, to reason together about these questions so that we as citizens can decide how to shape the forces that govern our lives.

My argument is not that we must never intervene in nature. My argument is that there is a moral difference between intervention for the sake of health, to cure or prevent disease, and intervention for the sake of achieving a competitive edge for our kids in a consumer society.

Aiming at health, restoring health - that is a goal that is both morally important and limited, because it aims at the restoration of normal human functioning, which is an important part of human flourishing.

First, individual rights cannot be sacrificed for the sake of the general good, and second, the principles of justice that specify these rights cannot be premised on any particular vision of the good life. What justifies the rights is not that they maximize the general welfare or otherwise promote the good, but rather that they comprise a fair framework within which individuals and groups can choose their own values and ends, consistent with a similar liberty for others.

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.

It's ultimately the purpose of education to cultivate the love of learning for its own sake.

Other animals can make sounds, and sounds can indicate pleasure and pain. But language, a distinctly human capacity, isn´t just for registering pleasure and pain. It´s about declaring what is just and what is unjust, and distinguishing right from wrong. We don´t grasp these things silently, and then put words to them; language is the medium through which we discern and deliberate about the good.
