Sharon Street is an American philosopher at New York University whose work centers on metaethics, particularly the relationship between evolutionary biology and moral realism. She is best known for her 'Darwinian Dilemma' argument, which contends that natural selection's shaping of our evaluative attitudes poses a fatal challenge to mind-independent moral realism. She defends a Humean constructivist position on the nature of practical reasons and moral value.
