Subjectivism about wellbeing rests on the idea that what is good for a person must ‘fit’ her, ‘resonate’ with her, not be ‘alien’ to her, etc. This idea has been called the ‘beating heart’ of subjectivism. In this article, I present the No-Beating-Heart Challenge for subjectivism, which holds that there is no satisfactory statement of this idea. I proceed by first identifying three criteria that any statement of the idea must meet if it is to provide support for subjectivism: Distinctness, Exclusiveness, and Explicitness. I then argue that no statement of this idea meets these criteria.
