The difference between "central idea" and "writing purpose"
"Central idea" and "writing purpose" are two common concepts in novel writing, but there is no clear relationship between them. Generally speaking, the "central idea" refers to the core content and theme of the novel. It is the soul and core of the entire novel, which outlines the main plot and character image of the novel, expressing the author's creative intention and creative concept. The central idea was usually expressed at the beginning or end of the novel. It was also an important concept that the reader could summarize and understand through reading the novel. Writing purpose referred to the author's creative purpose and intention in the process of writing, including the story plot, character creation, plot twist, ending, etc. It was an important part of the entire novel and the original intention and purpose of the author's creation. The purpose of writing may be expressed at the beginning or end of the novel through description, dialogue, etc., or it may be gradually revealed as the plot of the novel advances. Therefore, although the "central idea" and "writing purpose" are closely related, their ways of expression and emphasis are different. The central idea was the soul and core of the novel, which was an important concept that the readers could summarize and understand through reading the novel, while the purpose of writing was an important part of the novel creation, which was the original intention and purpose of the author.
