In the second half (Parts V and VI) of *Discourse on Method* [1637] Descartes gives his views on natural philosophy and his criteria for advancing the investigation of nature.
In Part V, Descartes sketches how in an unpublished treatise (published posthumously as *Le Monde*) he had laid out his ideas regarding the laws of nature, the sun and stars, the moon as the cause of the tides, gravitation, light, and heat. To avoid theological controversy, Descartes frames his mechanistic laws of nature as applying to a theoretical "new world" created by God. This hypothetical world would be a deistic universe.
In Part VI, Descartes admits his hesitation about publishing his work. But since people have begun to hear of the work, he felt compelled to publish small parts of it so that people do *not* wonder why he *doesn't* publish. Descartes says scientific experimentation is time-consuming, hard to delegate – and essential. He asks readers to test the claims in *Dioptrique*, *Météores*, and *Géométrie* and send their feedback to his publisher, with a promise to publish the questions with his replies.
