Context:

Interestingly, it was literary Symbolism in particular that anticipated the way that language has developed as an visual art form, not only because the poet Stephan Mallarmé produced important pioneering work that addressed
the plasticity of words on a page, but also because language orthodoxies were being challenged by other members of the movement.For example, the literary Symbolist Remy de Gourmont’s championing of the commonplace comes to mind when discussing Holzer’s frequent parodying of everyday platitudes. Referring to the commonplace as a recurring device in religious sermons, de Gourmont saw it as a means by which durable essences or abstract ideas could be represented to the congregation. Its brevity makes it accessible and its repetition in the mass chanting of simply understood phrases unites its audience.
