Different contexts and cultures do not necessarily align. An advisable intervention route in one culture could be antagonizing in an other, and visa versa. Cultural expressions and interactions could look like the inverse of each other.
What are our common grounds?
Without a shared history - and with limited interest or narrow communication channels for dissemination knowledge and intangible cultural heritage - in my view, common grounds are our shared, human values.
A worthwhile exercise would be the formulation of “The Universal Values of Humanity”. A really challenging excise, no doubt, and possibly one that could linger long.
Of course, we have got “The Universal Rights of People”, but that is just one side of a reality. Where are “The Universal Responsibilities of People”?
Can both be reconciled in “The Universal Values of Humanity”?
