 The first causes of sympathy, Grouchy argues, are the sensations of pains and pleasure one experiences as part of our relationship to another. A baby who finds comfort at the breast of its nurse will experience pain when it is separated from it, and later learn to recognize and care for the pain experienced by the nurse. Grouchy distinguishes between physical and moral pleasures and pains on the one hand, and present and remembered pleasures and pains on the other. She also argues that we can derive abstract ideas of pleasures and pains.
