Philippe Aries (1962) was the first sociologist to claim that the concept of childhood was invented, and that it did not exist until the 17th century. Since then many scholars began to discuss the concepts of childhood. This study is to examine the relationship between the concepts of childhood and the development of children's literature through a historical review both in the West and in Taiwan. It is found that the concepts of childhood and children's literature have been closely related to each other. Basically the concepts of childhood have effected the development of children's literature; however, in Taiwan the children's literature introduced from the West gave quite an influence to the development of the views of childhood. On the other hand, the Chinese traditional pragmatic value toward childhood also hinders children's literature from growing brilliantly. Consequently children's literature packed with didacticism finds it way to develop in Taiwan.
