There are some interesting parallels here between the development of scientific thinking and the development of literature:
The novel broke from those narrative predecessors that used timeless stories to mirror unchanging moral truths. It was a product of an intellectual milieu shaped by the great seventeenth-century philosophers, Descartes and Locke, who insisted upon the importance of individual experience. They believed that reality could be discovered by the individual through the senses. Thus, the novel emphasized specific, observed details. It individualized its characters by locating them precisely in time and space.
