According to Apostel, a worldview is an ontology, or a descriptive model of the world. It should comprise these six elements:
- An explanation of the world
- A futurology, answering the question “where are we heading?”
- Values, answers to ethical questions: “What should we do?”
- A praxeology, or methodology, or theory of action.: “How should we attain our goals?”
- An epistemology, or theory of knowledge. “What is true and false?”
- An etiology. A constructed world-view should contain an account of its own “building blocks,” its origins and construction.
1. There are many explanations of worldly phenomenon, and therefore many worldviews, i.e. etiologies.
(The multiplicity of perspectives, variably determined by the union of direct experience and the influence of the prevailing ideologies within any given context of culture, render unique explanations for every individual; while similarities exist, no two perspectives are completely commensurable. Socialization, or more specifically enculturation, is the single most important determinate in shaping a subjective perspective.)
2. Each explanation contains its own end, or futurology. (Explanations may change when a subject recognizes and challenges the limits of their experience and the latent ideology maintained by their subjective perspective.)
3. Values and ethics are dependent on these ends and seek to preserve these ends.
4. The justification of ends, i.e. the methodology for their achievement, is dependent upon the content of these values and ethics.
5. A subjects epistemology is determined by their perspective, which in turn yields their explanations. (See 1)
6. A world view is domain constituted by the propositional content and functionality maintained by a subjective perspective. (See 1-5.)
