In Western literary criticism, the debate between expressive and constructive theories represents a fundamental antithesis regarding the nature of the writer’s role.1

The Constructive Theory

The constructive school views the writer as a technician—akin to an architect or engineer—who designs a work to elicit a specific aesthetic response from an audience. This approach focuses on the theoretical construction of a piece, prioritizing structure and analytical principles. Aristotle is considered the primary representative of this school, particularly through his work Poetics, where he treats literary composition as a deliberate, objective craft.1

The Expressive Theory

Conversely, the expressive theory posits that the writer is a virtuoso who creates by giving voice to the deepest realities of their own personality. The power of the work to move readers stems from their profound identification with the author’s self-expression. This perspective is exemplified by the 1st-century treatise On the Sublime, which seeks to define greatness in literature through the lens of personal expression rather than technical rules.1

Ultimately, this tension has persisted throughout history, manifesting in movements such as Classicism versus Romanticism.1
