Understanding the meaning of common good is difficult because of its individualistic meanings. Defining an idea, may be useful looking at the opposites. The Oxford Dictionary defines turmoil as “a state of great disturbance, confusion, or uncertainty”. Turmoil for an individual is anxiety, for the collective it is civil disorder. Both anxiety and civil disorder are dysfunctional. Dysfunctionality means that something is not working. Therefore, any individual, or group of individuals in turmoil is the opposite of the common good.
The normal goal of any organism (individual or institutional) is homeostasis. This being the case then the objective of the common good is to eliminate turmoil. If you accept this premise, then the abstract common good idea becomes more tangible. Rather than trying to tackle the entire abstract idea, you begin by establishing the things that work against it. It is like building a structure, you lay out the foundation brick by brick. In this way, you create a solid substratum allowing a sustainable outcome as you grow the concept.
Trying to solve civil disorder is impossible, if you cannot understand the genesis of the turmoil. Disorder is the symptom of deeper underlying issues. Anxiety is not in itself the source, but the manifestation of inner turmoil. There is no difference between the anxiety of an individual and the anxiety (unrest) of the crowd.
Frequently we dismiss the herd anxiety, because it is difficult to understand its cause. Thus, we tend to judge and condemn the actions of the group as abnormal. Instead, we should see it as a normal reaction to underlying issues. It does not mean that there are individual who will take advantage of a situation to push their agenda. The agenda may be political or selfish. This is too easy; you must look beyond the rhetoric or the evil of individuals to ascertain the reason for this turmoil.
