"All one's inventions are true, you can be sure of that. Poetry is as exact a science as geometry"

In this quote, Gustave Flaubert is revealing his belief that all of one's creations, or developments, hold true in their own method. He suggests that even though they may not be based on factual evidence, they still hold a specific reality and validity. Flaubert then goes on to compare poetry to geometry, mentioning that it is just as precise and accurate as a scientific discipline. This highlights the concept that poetry is not just a form of artistic expression, but likewise an approach of understanding and analyzing the world around us. Flaubert's words remind us that imagination and creativity can hold simply as much truth as logic and factor.
