Bertrand Russell Quote

As a proposition of linguistics: "Energy" is the name of the mathematical expression in question...As a propo sition of psychology: our senses are such that we notice what is roughly the mathematical expression in question, and we are led nearer and nearer to it as we refine upon our crude perceptions by scientific observation.
