Why does Doctor Noir warn Stello to avoid direct political involvement?

In the work Stello (1832), Doctor Noir—who serves as a symbolic representation of the author's own intellect—advises the poet Stello to avoid direct political involvement to preserve the dignity of his art.1

Through a series of anecdotes, Doctor Noir demonstrates that various political regimes and ideologies, ranging from the levity of Louis XV to the fanaticism of Robespierre, consistently inflict a state of "perpetual ostracism" upon poets. By prescribing a separation between poetic life and political life, the doctor aims to protect the poet from the "horrible cruelties" and inherent fanaticism that characterize public and political arenas. Ultimately, this counsel reflects the author's own disillusionment with political authority and his belief that the poet must remain detached to maintain moral and artistic integrity.12
