从事任何科学研究都必须以客观事实为基础,在对事实的分析中提炼总结出具有规律性和指导意义的理论。没有事实,理论就无从建立;没有理论,事实就得不到分析和解释,一个学科的存在和发展也将是不可能的,因而这两者都极端重要,理想的状态是二者兼顾并重。但在研究实践中,却往往会出现倚重倚轻的现象:或材料宏富,而理论说明贫乏;或理论框架完备,而材料不足。就语言学领域而言,在这样一个基本问题上不同学者、不同流派之间一直存在着一些分歧。 Any scientific research must be based on objective facts, in the analysis of facts extracted summed up the regularity and guiding theory. Without fact, theory can not be established. Without theory, facts can not be analyzed and explained. It is impossible for a subject to exist and develop. Therefore, both are extremely important and ideal state takes both into consideration. However, in research practice, there is often a phenomenon of reliance on lightness, or the wealth of materials, and the lack of theory, or the complete theoretical framework and insufficient materials. In the field of linguistics, there have been some differences between different scholars and different schools on such a basic issue.
