Consider weltanschauung or worldview.
From Wiktionary on weltanschauung:
A person's or a group's conception, philosophy or view of the world; a worldview.
… and worldview:
- One's personal view of the world and how one interprets it.
- The totality of one's beliefs about reality.
- A general philosophy or view of life.
Also Wikipedia on worldview:
A worldview or a world-view or Weltanschauung is the fundamental cognitive orientation of an individual or society encompassing the whole of the individual's or society's knowledge, culture, and point of view. A worldview can include natural philosophy; fundamental, existential, and normative postulates; or themes, values, emotions, and ethics.
In my understanding this fails to capture the more practical aspects of philosophy, religion, and occultism such as applied ethics, rituals, or religious communities. However, my educated guess is that this is not what you are after.
