A worldview is a network of presuppositions not verified by natural science; in terms of which every aspect of experience is interrelated and interpreted.
This involves a person’s most basic and foundational beliefs. People cannot believe just one thing. They, by necessity, have a network of beliefs. Beliefs come in clusters (every single one being connected to and supporting another).
Nevertheless, within these clusters, there are central beliefs which are basic, foundational, and authoritative. The most basic of these beliefs are our presuppositions.
Presuppositions are clustered as well. Each presupposition in this cluster is dependent upon, determinative of and interrelated with each other. These presuppositions address the following issues:
1. The nature of reality (metaphysics)
2. Theory of knowledge (epistemology)
3. How we should live (ethics)
At the center of everyone’s beliefs is a cluster of presuppositions. These presuppositions are held by faith. Faith is whatever is believed without direct observation.
Since this is the case, presuppositions are adhered to religiously. Religion is not ritual; it is an ultimate commitment (what one lives and dies for). Everyone has such an ultimate commitment and this commitment guides every aspect of their life.
No one likes their ultimate commitments to be challenged; for it threatens their entire system and organization of thought. That is why they are religiously adhered to. It is convenient, safe, and easy to reject anything else. To renegotiate these beliefs would mess up one’s entire life. For one’s worldview is necessarily related to all experience and everyday affairs. One’s worldview provides coherence.
Everyone has a worldview. But not everyone has a rational and consistent one.
