fundamentalism

This term describes a rigid, uncompromising commitment to a set of core beliefs. While it is most frequently associated with religious contexts where sacred texts are interpreted literally, it also applies to secular ideologies, such as economic or political systems, where a foundational theory is applied without deviation.

In modern discourse, the word often carries a negative connotation, implying intolerance, dogmatism, or a refusal to adapt to changing social and intellectual landscapes. It suggests a binary worldview where the core tenets are viewed as absolute truths that supersede nuance or compromise.
