Cognitive closure (philosophy)
Cognitive closure refers to the concept in the philosophy of mind and philosophy of science that suggests human cognitive faculties are fundamentally incapable of solving certain philosophical problems. These problems, which have persisted throughout the history of philosophy, are considered beyond the reach of human understanding, not because of insufficient data or research, but due to inherent limits in the structure or capabilities of the mind.
