The Best Way to Avoid Wrongful Harm

It seems to me that the best way to avoid wrongful harm is to be able to identify which kinds of harm are genuinely wrongful. If we can't talk about things and discuss them, investigate the different views that people have, subject them to reasoned scrutiny, we're just going to be casting about blindly. We're much more likely to do harm through ignorance than we are through careful, reasoned discussion of issues. It's not as if we know the answers to these difficult moral issues a priori. We simply have to think these things through ifw unless we want to just be guided by ignorance.
