The quintessence of science is the Principle of Simplicity,which refers to logical simplicity and is based on the concept of falsifiability.Paradigm shift in scientific research is driven by the Principle.Simplicity or elegance is a measure of value in both physics and linguistics.The main body of this paper introduces many examples of carrying out the Principle in language studies both in China and abroad,and the work done by the author in this respect.The author calls for guarding against the effect of Inverse Occam's Razor,dispelling misunderstandings of the Principle of Simplicity,and paying attention to drawing a clear primary-secondary distinction.
