Glen: An emphasis on law's purely procedural side produces a concern with personal rights that leads to the individual's indifference to society's welfare.
Glen
The primary role of law should be to create virtuous citizens, but when we emphasize law's purely procedural side, it makes people more concerned with personal rights and less concerned with society's welfare.
Sara
If the role of law were to create virtuous citizens, it would mean that the government was deciding which types of life were virtuous. That would be a worse situation than having a government that's overprotective of individual's rights.
Evaluation
Does Sara argue against either of Glen's explicit claims?
Does she argue that emphasizing procedural law does not emphasize personal rights over societal well being? No, she seems to accept that part. She alludes to the idea that the government in this scenario might be overprotective of personal rights, which sounds like emphasis.
Does she argue that law's primary role should not be to create virtuous citizens? Yes, it seems like she's arguing in that direction, because she thinks it's dangerous for the government to be trying to decide with types of lives are truly virtuous.
Goal
They seem to be fighting over whether law's primary role should be to create virtuous citizens, or whether it's better for a government to be overprotective of personal rights or better for a government to be deciding on what would make a virtuous citizen.
