A worldview is a person's set of assumptions about the basic makeup and nature of the world and universe.
We all have a worldview. It is how we see and interpret our world. One definition of worldview is: "The totality of one's beliefs about reality.
There are only four truly important questions in life: Who am I? Where did I come from? Why am I here? Where am I going when I die? How you view your world will determine how you answer those four questions.
Most people have a pair of philosophical worldview glasses that they usually wear, and usually, like a pair of sunglasses, often do not realize they have them on.
Most people are unable to tell where science or reality ends, and their philosophical belief system begins. They continually equate their philosophical interpretations of scientific evidence with the evidence itself, and perceive them to be the same thing.
Like wearing regular sunglasses, if you try to remove them so they can see clearly, they jump back and try to defend themselves as if under attack, not realizing someone is trying to help them.
The best reason for separating our worldview from science is for the sake of good science itself. Agendas and worldviews may be affecting science more than we often are aware of.
Learning to tell the difference is a difficult task. We need to ask ourselves, is the integrity of the field of science worth the effort?
