"In writing this work, I set out to answer this question: How, in the name of what conceptions, according to what method, by what means, if we can know, - was the Coup de Dés made? In the interest of my business, I have submitted to observing several rules, which I believe I can formulate as follows: Group and compare analogous facts and find out if a guiding idea emerges from their comparison. Group and compare these guiding ideas and investigate whether from their comparison emerges a central aesthetic conception, capable of claiming the primitive conception and allowing the poem to be enclosed in a higher synthesis."
