A medical ethicist recently proposed that selecting (and possibly engineering) certain traits into our children is not just morally permissible but desirable:
Professor Julian Savulescu said that creating so-called designer babies could be considered a "moral obligation" as it makes them grow up into "ethically better children".
The expert in practical ethics said that we should actively give parents the choice to screen out personality flaws in their children as it meant they were then less likely to "harm themselves and others".
I am curious what schools of thought there are in the philosophical community (or individual viewpoints) regarding this issue.
Is any sort of interference morally problematic? (Many would think so intuitively, especially within religious communities, but intuition can be wrong.)
If selection and screening are okay, is introducing new genes okay/desirable also--assuming that we know what the impact will be--or is there a fundamental difference between selecting between possibilities that already were going to occur, and creating people with a new genetic composition that they couldn't have acquired "naturally"?
