This document explores what the number four represents on deeper levels beyond its typical definition as a countable quantity. It discusses how Buddha used silence and a flower to convey an "abstract thought" to Mahakasyapa that could not be expressed through words. The document then traces the development of logic from ancient Greek philosophers like Pythagoras and Plato. Finally, it argues that the number four is best understood as a symbolic representation of the abstract, non-physical concept it denotes, allowing us to interpret and quantify the concrete world.
