So to analyze in the aspect of description, it is useful to delouse the fount how inarticulateness comes into being; Based on the economic relationship and from the viewpoint of the pursuit of aim, the object of studying, the original creation of aesthetics, as well as the articulate knowledge and inarticulate knowledge, Polanyi distinguished the acquisitive way of science and technology. The development model of personal Knowledge can be generalized as the enthusiasm of seeking knowledge; Polanyi revealed how personal factors of mathematician cut across logical chasm, and gained mathematics findings in math" s activities. Thus he proved mathematics was also activity-needed techniques as natural science; Last evaluating the theory of "Personal Knowledge systematically, it can reveal its realistic significance and limitation.

波兰尼把认知结构区分为可言传知识与不可言传知识，与20世纪以来西方哲学的中心课题转向语言学的研究一致，所以从言述的角度出发，有助于了解不可言传性如何形成的根源；波兰尼以经济关系为立足点，从科学与技术的目的追求、研究对象、美的原创性，以及从可言传知识与默会知识的角度对两者的获取途径做了区分；其个人知识发展模式可以概括为：求知热情→启发性热情→说服性热情……；波兰尼揭示出数学家的个人因素是如何在数学活动中跨越逻辑鸿沟，取得数学发现的，从而证明数学同自然科学一样，也是一项需要技能的活动；最后对&个人知识&理论作一系统的评价，揭示&个人知识&理论的现实意义和局限性。
