Abstract
We discuss the significance of Einstein’s second postulate of the special theory of relativity (STR) stipulating the constancy of the speed of light in vacuum. The causality that follows from the STR may be a more general principle to organize our knowledge of all phenomena. In particular, quantum dynamics can be derived using the causality principle. Causality does not prohibit quantum mechanics to be non-local, and this has implications in the real world.
