Feelings of pain or pleasure or some quality in between are the bedrock of our minds. We often fail to notice this simple reality because the mental images of the objects and events that surround us, along with the images of the words and sentences that describe them, use up so much of our overburdened attention. But there they are, feelings of myriad emotions and related states, the continuous musical line of our minds, the unstoppable humming of the most universal of melodies that only dies down when we go to sleep, a humming that turns into all-out singing when we are occupied by joy, or a mournful requiem when sorrow takes over.

Given the ubiquity of feelings, one would have thought that their science would have been elucidated long agowhat feelings are, how they work, what they meanbut that is hardly the case. Of all the mental phenomena we can describe, feelings and their essential ingredientspain and pleasureare the least understood in biological and specifically neurobiological terms. This is all the more puzzling considering that advanced societies cultivate feelings shamelessly and dedicate so many resources and efforts to manipulating those feelings with alcohol, drugs of abuse, medical drugs, food, real sex, virtual sex, all manner of feel-good consumption, and all manner of feel-good social and religious practices. We doctor our feelings with pills, drinks, health spas, workouts, and spiritual exercises, but neither the public nor science have yet come to grips with what feelings are, biologically speaking.

I am not really surprised at this state of affairs, considering what I grew up believing about feelings. Most of it simply was not true. For example, I thought that feelings were impossible to define with specificity, unlike objects you could see, hear, or touch. Unlike those concrete entities, feelings were intangible. When I started musing about how the brain managed to create the mind, I accepted the established advice that feelings were out of the scientific picture. One could study how the brain makes us move. One could study sensory processes, visual and otherwise, and understand how thoughts are put together. One could study how the brain learns and memorizes thoughts. One could even study the emotional reactions with which we respond to varied objects and events. But feelingswhich can be distinguished from emotions, as we shall see in the next chapterremained elusive. Feelings were to stay forever mysterious. They were private and inaccessible. It was not possible to explain how feelings happened or where they happened. One simply could not get "behind" feelings.
