 Smith relates sympathy to approval. For a spectator to approve of an agent’s feelings is for him to observe that he sympathises with the agent. This account is used as the basis of the analysis of propriety. For a spectator to judge that an agent’s act is proper or appropriate is for him to approve of the agent’s act. The agent’s act lacks propriety, in the judgment of the spectator, if the spectator does not sympathise with the agent’s performance.
