Sensibility, defined as an acute awareness of emotions and the environment, emerged in 18th-century Britain, blending philosophy, medicine, and literature. Initially associated with heightened perception and moral understanding, as John Locke proposed, it became central to sentimental novels, where characters like those in William Hill Brown’s works responded strongly to emotional stimuli.
However, critics like Samuel Johnson condemned such extremes as self-centered theatrics, a theme addressed in Jane Austen’s Sense and Sensibility. Mary Wollstonecraft praised sensibility as a quality that nurtured genius, while Th. Ribot investigated its ongoing psychological impact. This duality—viewed as empathy yet criticized as weakness—shaped discussions about the role of emotion in morality and art.
