Final answer:
The term 'immutable' means something that is fixed or cannot be changed. Belief in immutable destiny aligns with the concept of fatalism, which holds that all events are predetermined and inescapable.
Step-by-step explanation:
The term immutable refers to something that is fixed or unchangeable. In the context of discussions about destiny and determinism, those who believe our destinies are immutable think that our paths are set and cannot be altered. This belief aligns with the concept of fatalism, which asserts that all events are predetermined and therefore unavoidable. Fatalism often includes the assumption that either universal causation governs all events, or that some form of divine omniscience determines the future. On the other hand, some philosophical arguments, like those in favor of libretext or cultural pluralism, suggest that choices and human actions can influence the future, rejecting the notion of an inexorable fate.
