Ode In (Co) Existence

Dear reader,

I am currently reading about the anatomy of the body and I cannot help but comment on the perfection of this system. Together with this thought I had several others about the operation of systems and their individual parts based on recent events in Greek society.

The body is an organism consisting of liquids and solids (and gases) of different dimensions, shapes, capacities and functions that work together every moment to keep the organism alive. At the same time, it cooperates with its external environment, with the air that surrounds it (breathing), the bacteria, the food it it needs to continue living, etc.

At any time anything from this well-organised chain can stop working or start operating in a different way. Many of the diseases that occur in a body have exactly this cause and we strive in every way to bring it back to its 'normal' or smooth function. The evolution of man allowed a specific science, medicine, to create and administer drugs, to operate, to replace parts of our body and to try on the basis of what he knows to restore the system to a good functional state.
It is truly miraculous how much we have evolved to be able to intervene in nature and prolong life.

We could extend this reasoning to other aspects of human life. For example, human society (whether it is a village, a city, a country or humanity as a whole) is a system and every person is a member of that system. The system was formed evolutionary as it was better for its members to survive. Every man undertakes a function within the society that serves, simultaneously, his own survival and the survival of his society as a whole.

Of course, over the years societies became more and more complex and from only hunting, cooking and protecting the new members the collective tasks expanded into technical works of materials, law, accounting, education, psychology and so many others that daily ensure not only the survival of the system but its prosperity and wealth, how it expands its activity and thus its existence. The proper functioning of such a complex system requires rules and a mechanism that will be responsible for their implementation, that is law and the judicial system.

In this process of expansion we are witnessing today two seemingly opposite things.
First, man through studying the world finds that as a planet and species we are part of a larger system (galaxy, universe) and at the same time within the planet man distinguishes himself from other people, he has created  subsystems.
We have the system of organism (body) and outside the environment (including other people), we have larger systems such as family, close people, like-minded people, religion and ethnic comrades and so on.

Every system is selfish, it aims first and foremost towards its survival and for this reason it will do everything to defend its members and its own self when it feels threatened, including murdering someone, just as our ancestors did when the were threatened by wild animals.
In this light, it is easily explainable (but not acceptable) that people continue today to kill other people because they are not the same as them, because they do not agree with them. because they do not do the same things with them, because they experience them as a threat to their system or, worse, as not worthy to live, otherwise they would have no reason to eliminate their presence.

Any man who turns against another man by attempting to eliminate him in any form (physical, emotional, spiritual) is the same thing as a cell in an organism that decides to work against other cells and against the organism that it lives in.

The 'medicine' of behaviour, justice (or better penitentiary), as well as the medicine of the body, have corrective functions where a symptom has been shown already.
Who has the role, therefore, the responsibility to operate precautionary in favour of health and against illness within a system?
Where can we hide the causes of a pathogenicity where a part of a whole is directed against another part of the same whole and how does the whole respond this pathogenicity?

Will we ever be able to live in conscious harmony with ourselves and with our broader environment just as our body does on its own every day in order to continue living?

With Love,
Panos
