gnosticism

This term describes a specific theological framework where the physical universe is viewed as a flawed creation, often attributed to a lesser deity, rather than the supreme divine source. It carries a connotation of exclusivity and mystery, as it emphasizes a hidden truth accessible only to an enlightened few through direct spiritual experience rather than faith or tradition.

As an abstract noun referring to a system of belief or a philosophical school of thought, it is treated as an uncountable mass noun. It does not have a plural form in standard usage, as it represents a singular conceptual category of ancient heresy or mysticism.
