Final answer:
A group of people does not need to have a written language to be considered civilized. Civilization is defined by various factors such as social structures, cultural practices, and the ability to live together in organized communities. While a written language can facilitate communication, there have been civilizations throughout history that thrived without one.
Step-by-step explanation:
Written language is not necessarily a requirement for a group of people to be considered civilized. Civilization is more broadly defined by the development of social structures, cultural practices, and the ability to live together in organized communities. While a written language can facilitate communication and the exchange of ideas, there have been civilizations throughout history, such as some Indigenous cultures, that thrived without a formal system of writing. For example, the Inca civilization in South America relied on quipus, a system of knots on strings, for record-keeping and communication.
Additionally, there are many factors that contribute to civilization, including agriculture, technology, governance, and social organization. These aspects can be present and developed in a society without the existence of a written language. The San people of South Africa, mentioned in the provided text, had a complex social structure and system of customs to maintain order, even though they did not have a written language.
It's important to recognize that while a written language can be an important tool for communication and preservation of knowledge, it is not the sole determinant of civilization.
