Common knowledge refers to information or facts that are widely known, understood, and accepted by a majority of people within a particular society or community. It refers to knowledge that is publicly available, easily accessible, and commonly taught or shared in educational institutions or through cultural channels. Common knowledge is usually acquired through general exposure to the world around us, education, and social interactions.
Common knowledge encompasses a broad range of topics, including historical events, scientific principles, cultural traditions, and basic information about the world. It includes facts that are generally accepted without requiring specific sources or references because they are considered true and well-known to the general population. For instance, the fact that water boils at 100 degrees Celsius or that the sun rises in the east and sets in the west are examples of common knowledge.
Additionally, common knowledge is subject to change over time and can vary across different cultures or regions. It is often used as a foundation for further knowledge and is expected to be known in order to have well-informed conversations or participate in social interactions.
In academic settings, writers often need to be cautious about relying solely on common knowledge, as proper citation and referencing of sources is necessary to substantiate claims and maintain academic integrity. However, in everyday conversations or informal contexts, common knowledge serves as a shared understanding that allows individuals to communicate effectively and comprehend each other's ideas.
The word "common knowledges" is a combination of two words, "common" and "knowledge".
1. Common:
The word "common" comes from the Old English word "cȳm(e)ne", which means "belonging to all" or "public". It ultimately stems from the Proto-Germanic word "kamnaz", which means "together". In Latin, "common" translates to "communis", which carries a similar meaning. Over time, the word "common" has retained its essential meaning of something that is shared or available to all.
2. Knowledge:
The term "knowledge" has its roots in the Old English word "cnāwlece", which is derived from the Proto-Germanic word "kunnan", meaning "to know". The Old English term gradually evolved into "knowleche" in Middle English before becoming the modern English "knowledge".
