The concept of the "law of universal causation" refers to the belief that every event or phenomenon has a cause or causes that can be traced back through a chain of causality. It is an integral principle in various fields, including philosophy, physics, and metaphysics. Synonyms for this profound principle include the "principle of causality", "causal determinism", or simply the "causal law". These terms express the notion that everything in the universe has a cause and effect relationship, establishing a logical framework that governs the interconnectedness of all things. Such interchangeable synonyms serve to emphasize the pervasive nature of causation within the universal fabric.
