“The Forgotten Sense leaves us with the hope of new discoveries and new recoveries—so that we may once again revel in the glorious, fragrant world around us.”—Wall Street Journal

By one of the world’s leading researchers into the science of smell, a fascinating exploration of our most essential yet least understood sense—enabling us to appreciate food and drink, warning us of dangers, and even influencing who we fall in love with

Our sense of smell guides our lives far more than our screen-heavy, sight-privileged era would suggest. It animates our experience of food and drink, helps us access memories, and strengthens our intimacy with each other. But, long considered our most “beastly” sense, the inner workings of smell have stumped scientists for centuries.

Now, cognitive scientist and leading smell researcher Jonas Olofsson uncovers the sophisticated processes that drive our olfactory system, with profound implications for how we perceive the world around us. Drawing from cutting-edge original research, Olofsson shows that not only is our sense of smell extraordinarily sensitive, its process of chemical exchange shaped human evolution on its most fundamental level.

From the pheromones, environmental signals, and emotions we process with each breath, olfaction makes us the individuals we are. Moreover, smelling is an intellectual exercise, Olofsson argues, one that we have the remarkable capacity to strengthen and, with some effort, even regain after illness.

With infectious curiosity and a host of applications—from emotional health and gastronomy to literature and even politics—The Forgotten Sense is a wide-ranging and entertaining look at this most understudied function of human life.
