The different songs performed ( Homo cantor) and the different proverbs evoked (Homo educandus) in different circumstances of life are part of the collective memory of a given people, becoming aware of them expresses human authenticity or congruence (knowing how to assume oneself and be a conveyor belt of one's culture) and making them a sentinel of one's cultural identity opens one's mind to discover common denominators or cultural invariants between different cultures and thus making cultural diversity a richness.
