Spirit has many different definitions. We generally define the concept of spirit in this sense: it is an intentional existence within human beings, an organic unity of many psychological factors of human rationality and sensibility, and a psychological activity process of human beings constantly surpassing themselves and perfecting themselves.
Therefore, spiritual value is different from material value, and spiritual value is internal, ontological and constantly surpassing itself. Literary creation is the spiritual activity of literary and art workers, literary works belong to the spiritual products of human beings, and the acceptance and appreciation of literature and art also belong to human spiritual activities.
Information literature in a broad sense is one of the humanities, and it ranks at the top of the social building alongside philosophy, religion, law and politics. It originated from human thinking activities. Oral literature first appeared, usually combined with music to form lyric poems that can be sung. The earliest written documents are China's The Book of Songs, Indian Ramayana and ancient Greek Ilion Ji.
China's works written in words in the pre-Qin period were collectively referred to as literature, and literary works were listed separately only after Wei and Jin Dynasties. The classification of European traditional literature theory divides literature into three categories: poetry, prose and drama. Modern literature is usually divided into four categories: poetry, novel, prose and drama.
