Answer 2

Unity in diversity is a concept of "unity without uniformity and diversity without fragmentation"[1] that shifts focus from unity based on a mere tolerance of physical, cultural, linguistic, social, religious, political, ideological and/or psychological differences towards a more complex unity based on an understanding that difference enriches human interactions. It has applications in many fields, including ecology,[1] cosmology, philosophy,[2] religion[3] and politics.[4]

The idea and related phrase is very old and dates back to ancient times in both Western and Eastern Old World cultures. The concept of unity in diversity was used by both the indigenous peoples of North America and Taoist societies in 400–500 B.C. In premodern Western culture, it has existed in an implicit form in certain organic conceptions of the universe that developed in the civilizations of ancient Greece and Rome.[1]

"Unity in diversity" is used as a popular slogan or motto by a variety of religious and political groups as an expression of harmony and unity between dissimilar individuals or groups. The phrase is a deliberate oxymoron, the rhetorical combination of two antonyms, unitas "unity, oneness" and varietas "variety, variousness". When used in a political context, it is often used to advocate federalism and multiculturalism.
