Baudelaire witnessed a number of important historical events firsthand. One of his early childhood memories was the 1830 Revolution. His stepfather was a general in the army, meaning that political events had a great impact on his personal life. As he grew to dislike his stepfather he, thus, grew to dislike the government. For example, during the 1848 Revolution his stepfather led the troops that quelled the insurrection, while Baudelaire exhorted a mob to go kill him. He was also extremely disappointed at Louis-Napoleon's coup d'état, which ended the Second Republic. Thus, the rapid societal and political changes Baudelaire witnessed led him both to respect and abhor tradition. Consequently, his poems both follow specific rules and break them. Yet his overriding reaction to this tumultuous era was a feeling of alienation, especially in light of the swift rebuilding of Paris in the 1850s. As a result, his poetry often addressed feelings of isolation, failure, the fear of death, as well as nostalgia for a less industrialized time.
Throughout
Ostensibly a description of an encounter between two lovers, "To a Passerby" is actually a poem about deception, death, and the impossibility of love. Emerging from the threatening background of the city, the woman is first compared to a statue. But her seductive beauty elicits not only the obsessive stare of the speaker but a temptation toward death. The modern city prohibits a healthy or normal encounter: The speaker's passion is destined to wither away for "eternity"—the next time they will meet will be in death. Love, overshadowed by spleen, becomes impossible because "pleasure kills." The pain of the woman's fleeting presence leads the speaker to doubt if she ever even existed.
