Historically speaking, the arts were typically grouped into two modes: ‘classic’ and ‘romantic’. ‘Sensibility’ looks at the more recent academic move to use the term sensibility to describe a development against classical norms that took place in the mid-18th century. What does sensibility mean within this context? Sensibility fits into the following three periods: Classicism or Neoclassicism, sometimes also called the Augustan Age (1660–1740); Sensibility (1740–1789); and Romanticism (1789–1832). Definitions of the classical versus definitions of the Romantic are examined, and Romanticism as a rebellion against classicism and the Enlightenment outlined. The cult of Ossian, its influence across Europe, and its place within Romanticism is explained.
