While general ethical training exists, a focus on collegial ethics is required to develop this needed field. Some might argue that this is just general ethics and no special attention to collegial aspects is needed. But, as noted above, we have subfields of ethics that include business ethics, situational ethics, medical ethics, etc. This is useful to provide an emphasis on the subfield and it helps its development. Collegial ethics is no doubt as important as any other subfield, and perhaps it is even a foundation of some of them. It clearly deserves its own identity and special effort.

Why should I pay attention to collegial ethics? Isn’t it just common sense? Well, it is often common sense, but, for example, Voltaire said that common sense is not so common!

Collegial behavior is becoming more and more important in an interactive world.

Having a personal belief, solely and simply by itself, cannot justify harmful actions to others. The actions and their consequences must be judged by themselves and independent of underlying beliefs.
 

Simple dislike of a person can never justify destructive actions toward that person.
