Showing concern through mutual responsibility
We evolved into a fully interconnected world where each person depends on everybody else, each being fully responsible for all.
Thus showing concern for the community means taking on the inevitable mutual responsibility for others in increasing circles through a purposeful and highly practical method, where each learns how to make calculations for the benefit of the collective above personal benefit.
After all, if I am but an individual cell in a huge, living organism - which we have become as a result of Nature’s evolution - my life depends on the health, optimal development of the whole organism.
