Sentimentalism in eighteenth-century Scottish literature reflected the ideas of moral philosophers like Francis Hutcheson, David Hume and Adam Smith, who argued that our sense of morality has its origins in feelings aroused by impressions conveyed by the senses. The influence of Smith’s concept of the impartial spectator, an imaginary witness and judge of human interactions, is evident in novels by Henry Mackenzie and Tobias Smollett, whose characters’ emotional responses to scenes of suffering are described in great detail. In theatre, John Homes’ Douglas was deemed a success by the amount of tears shed by the audience, while Joanna Baillie’s plays dramatised moral sentiments by illustrating particular vices and virtues. Macpherson’s Ossianic poems became an international sensation through their nostalgic sentimentalism, which depicted the pure and noble virtues of a bygone era. Sentimentalism in the poetry of Robert Burns celebrates both individual subjectivity and common humanity through his treatment of universal themes like love and nature. Unlike the Romantic movement that would follow it, which tended to privilege individual autonomy and subjectivity over sociability, sentimentalism in Scottish literature depicted individuals as social beings whose sensibility was stimulated and defined by their interactions with others.
