Manual of Artistic Anatomy (1852) – but abandoned them as unreliable, although Shakespearean quotations are scattered through the text. It is notable also that Darwin does not include a discussion of deception in his psychology of emotional expression. Structure Darwin opens the book with three chapters on "the general principles of expression", introducing the rather Lamarckist phrase serviceable associated habits. With this phrase, Darwin seeks to describe the initially voluntary actions which come together to constitute the complex expressions of emotion. He then invokes a principle of antithesis, through which opposite states of mind induce directly opposing movements. Finally, he discusses a direct action of the nervous system, in which an overflow of emotion is widely discharged, producing more generalised emotional expression. This is followed by a section (three more chapters) on modes of emotional expression peculiar to particular species, including man. He then moves on to the main argument with his characteristic approach of astonishingly widespread and detailed observations. Chapter 7 discusses "low spirits", including anxiety, grief, dejection and despair; and the contrasting Chapter 8 "high spirits" with joy, love, tender feelings and devotion. In his discussion of "low spirits", Darwin writes: "After the mind has suffered an acute paroxysm of grief, and the cause still continues, we fall into a state of low spirits, or we may be utterly cast down and dejected. Prolonged bodily pain, if not amounting to an agony, generally leads to the same state of mind. If we expect to suffer, we are anxious; if we have no hope of relief, we despair." Subsequent chapters include considerations of "reflection and meditation" (associated with "ill-temper", sulkiness and determination), Chapter 10 on hatred and anger, Chapter 11 on "disdain, contempt, disgust, guilt, pride, helplessness, patience and affirmation" and Chapter 12 on "surprise, astonishment, fear and horror". In his discussion of the emotion of disgust, Darwin notes its close links to the sense of smell, and conjectures an association with excretory products. In Chapter 13, Darwin discusses complex emotional states including self-attention, shame, shyness, modesty and blushing. Darwin describes blushing as "the most peculiar and most human of the expressions". Darwin closes the book with Chapter 14 in which he recapitulates his main argument: he shows how human emotions link mental states with bodily movement, and are genetically determined, deriving from purposeful animal actions. He comments on the implications of the book: a single origin for the
