Final answer:
In Vidal's formulation, holding a worldview is considered to be essential, as it shapes how individuals perceive and interact with the world around them.
Step-by-step explanation:
In Vidal's formulation, holding a worldview is Essential. A worldview encompasses the fundamental cognitive orientation of an individual or society encompassing the entirety of the individual or society's knowledge and point of view. It is a system of beliefs, values, and understanding that influences how a person perceives and interacts with the world. Accordingly, having a worldview is important because it helps to frame our thoughts, actions, and perspectives, guiding us through the complex social and natural world. Just as we cannot analyze a scientific element without considering its essential properties, we cannot fully understand human actions or societal developments without acknowledging the role of worldviews.
