This paper is the first in a series of study on Lin Yao-de and his writings. In this paper, I examine Lin's early works that have not yet received critical attention in order to discover the nutrients for his mind, thoughts, and personality.Most scholars assumed that Lin was critical and anti-traditional in nature and that Wen Rui-an incident was a major turning point of life for him. However, growing up in a traditional (Chinese) family, Lin was conventional in many ways. By examining many unpublished manuscripts of his early years, I come to a conclusion that Lin was educated to conform with the traditional sentiments, value, and characteristic of the scholar. This family background shaped his mindset in writing and this influence will be demonstrated with textual evidence.In my preliminary research, the changes of Lin’s writings from his teenage to adulthood could be observed in the following four aspects: from being sentimental to intellectual, from expressing private emotions to holistic concern, from studying human civilization to exploring cosmic mysteries, and from tracing literary canons to breaking relevant conventions, deconstructing genres and constructing novel ideas. These aspects will be discussed in the next paper, ”Split and Cross: Study on Adult Lin Yao-de and his Literary Fields of Vision.”
