Adults envy the openhearted and open-minded explorations of children; seeing their joy and curiosity, we pine for our own lost capacity for wide-eyed… - Gabor Maté

Boredom, rooted in a fundamental discomfort with the self, is one of the least tolerable mental states.

The addict’s reliance on the drug to reawaken her dulled feelings is no adolescent caprice. The dullness is itself a consequence of an emotional malfunction not of her making: the internal shutdown of vulnerability.
From the latin word vulnerare, ‘to wound’, vulnerability is our susceptibility to be wounded. This fragility is part of our nature and cannot be escaped. The best the brain can do is to shut down conscious awareness of it when pain becomes so vast or unbearable that it threatens to overwhelm our capacity to function. The automatic repression of painful emotions is a helpless child’s prime defence mechanism and can enable the child to endure trauma that would otherwise be catastrophic. The unfortunate consequence is a wholesale dulling of emotional awareness. ‘Everybody knows there is no fineness or accuracy of suppression,’ wrote the American novelist Saul Bellow in The Adventures of Augie March; ‘if you hold down one thing you hold down the adjoining.’
Intuitively we all know that it’s better to feel than not to feel. Beyond their energizing subjective change, emotions have crucial survival value. They orient us, interpret the world for us and offer us vital information. They tell us what is dangerous and what is benign, what threatens our existence and what will nurture our growth. Imagine how disabled we would be if we could not see or hear or taste or sense heat or cold or physical pain. Emotional shutdown is similar. Our emotions are an indispensable part of our sensory apparatus and an essential part of who we are. They make life worthwhile, exciting, challenging, beautiful and meaningful.
When we flee our vulnerability, we lose our full capacity for feeling emotion. We may even become emotional amnesiacs, not remembering ever having felt truly elated or truly sad. A nagging void opens, and we experience it as alienation, as profound as ennui, as the sense of deficient emptiness…

Settling for the view that illnesses, mental or physical, are primarily genetic allows us to avoid disturbing questions about the nature of the society in which we live. If “science” enables us to ignore poverty or man-made toxins or a frenetic and stressful social culture as contributors to disease, we can look only to simple answers: pharmacological and biological.

Much of what we do arises from automatic programming that bypasses conscious awareness and may even run contrary to our intentions, as Dr. Schwartz points out:
The passive side of mental life, which is generated solely and completely by brain mechanisms, dominates the tone and tenor of our day-to-day, even our second-to-second experience. During the quotidian business of daily life, the brain does indeed operate very much as a machine does.
Decisions that we may believe to be freely made can arise from unconscious emotional drives or subliminal beliefs. They can be dictated by events of which we have no recollection. The stronger a person’s automatic brain mechanisms and the weaker the parts of the brain that can impose conscious control, the less true freedom that person will be able to exercise in her life. In OCD, and in many other conditions, no matter how intelligent and well-meaning the individual, the malfunctioning brain circuitry may override rational judgment and intention. Almost any human being when overwhelmed by stress or powerful emotions, will act or react not from intention but from mechanisms that are set off deep in the brain, rather than being generated in the conscious and volitional segments of the cortex. When acting from a driven or triggered state, we are not free.
