Does content exist before form? Furthermore, is there a hierarchy between form and content? There can be no precedence or superiority between form and content because they are inseparably intertwined, each enabling the existence of the other. Asking about precedence or superiority is akin to asking, “Which came first, the chicken or the egg?” Regardless of which comes first, form gives rise to content, and content gives rise to form. 《Which Came First》 reveals that there can be no before and after, no superior or inferior, between the two by reversing the conventional order of form and content through an experimental process that inverts the typical stages of book creation.
