The term in question refers to a set of basic beliefs, understandings, and practical judgments considered ordinary or reasonable by the majority of people. It encompasses the knowledge and abilities that are acquired through everyday experience and are typically shared within a given culture or society. An example of this would be recognizing that fire is hot and should be avoided, or understanding that if one plants seeds, one can expect plants to grow. These are assumptions and principles that are so widely held that they are rarely explicitly questioned.
Its value lies in facilitating social interaction, enabling individuals to navigate daily life effectively, and providing a foundation for more complex reasoning. Historically, this concept has been used to justify certain actions or beliefs, often without the need for further explanation or proof. Its widespread acceptance contributes to social cohesion and allows for efficient communication, as it provides a shared understanding of fundamental principles and expectations.
