Suppose that over the next couple decades, the study of the brain provides solid evidence that certain kinds of behavior promote/hinder human flourishing. How might we use such information or enforce a "new" morality? Can we keep all our freedoms?
(By the way, I think the findings will be more or less a confirmation of things we already seem to "know," however, when dealing with matters of fact, policies might be more justifiable. For instance, wearing a seat belt has proven to be safer than not, so now its a law.)
I want to keep the questions above open for discussion, but...
One of the biggest issues I foresee is that we will continue to discover the importance of early childhood in shaping who we are (our moral selves especially). In this hypothetical future, "good" parenting might require more than some are willing to give. How sacred is our right to parenthood?
