The Scent of Desire: Discovering Our Enigmatic Sense of Smell

Herz, a Brown University professor specializing in the psychology of smell, demonstrates that this sense is vital to our well being—so important to mental and physical health that its loss can drive some people to suicide. Herz explores the relationships between scent, emotion and behavior, emphasizing that scent is an important component of sexual attraction and thus crucial for the survival of our species. Many intriguing facts enliven her book. For example, scents are intimately connected to memory and can be used as memory aids; olfaction shuts down while we are asleep; newborns and their mothers recognize each other by their scent. Herz debunks the mystique of aromatherapy, which she says is effective because of our emotional associations with scents rather than because of any direct action of the scent. Emerging technologies of scent, such as electronic noses that can sniff out terrorists, breath analyzers that can detect diseases and marketing theories based on scents, are given a chapter, but Herz admits that she would rather see the development of technologies to restore the sense of smell to people who have lost it, because for her, scent “is essential to our humanity.” This illuminating book argues convincingly that the sense of smell should never be taken for granted.
