Song Meaning
This poem immediately throws down a gauntlet, declaring a radical, almost shocking, form of fidelity. The speaker isn't bound by promises or oaths; their only true allegiance is to the abstract concept of 'love's self.' This isn't a gentle confession but a bold assertion of a self-serving, yet strangely pure, devotion to the feeling itself, not to any specific person or commitment.
The central tension lies in the speaker's conditional loyalty. They explicitly state they would leave if the beloved ceased to be 'lovely' or 'hunger's rarest food.' This isn't about enduring hardship or staying out of obligation; it's about a constant, active pursuit of beauty and satisfaction. The speaker's desire is paramount, and the beloved is only worthy as long as they embody those qualities.
The real brilliance emerges in the final lines, where the speaker finds a loophole in their own self-declared creed. Because the beloved is 'changeful' and 'mobile,' the speaker can remain 'faithful' by simply following their constant shifts. The paradox is that the speaker's 'faithless' nature is mirrored by the beloved's own inconstancy, allowing the speaker to be 'most faithless' (in their commitment to a static vow) when they are 'most true' (to their core desire for beauty and their beloved's ever-changing allure).
This intricate dance of conditional love and mutable beauty makes the poem resonate. It captures a specific, perhaps uncomfortable, truth about attraction: that sometimes, staying together requires not steadfastness, but an agile embrace of change. The speaker's honesty, however brutal, about their motivations and their clever justification for staying creates a compelling, if morally ambiguous, portrait of desire.
