One morning, my father died at home. I awoke to a call for help – my name shouted once, loudly, desperately, fearfully, by my mother – ran into my parents’ bedroom, and found my father convulsing in the throes of a massive heart attack. His body bucked on a deadly trampoline, his chest heaved, spittle flecked his lips and the sides of his mouth as he desperately sought to fill his lungs with air. By the time our friendly family doctor arrived, stethoscope and black bag in tow, my father was dead. A dashing pilot and war hero, he had flown supersonic fighter jets in two wars, evaded anti-aircraft fire and airborne interceptors, only to come home and die as his wife and two sons looked on helplessly. Bullets and shells had missed their mark; a clogged artery, a fragment of plaque, had not. He was 43 years old. I was 12.

Fourteen years later, after a protracted struggle with breast cancer that included a disfiguring mastectomy, adjuvant chemotherapy, blasts of directed radiation, hormonal treatment, and a four-year remission, my mother, too, succumbed and passed away. Her last days were painful, mind-numbingly so. She was nauseated, incoherent, delirious, sleepless, her skin yellowed by her failing liver, her lungs crushed. The morphine we asked her doctors to administer made her catatonic and slowed her pulse to a barely discernible crawl. I had become unrecognisable to her; she to me. She was 52 years old. I was 26.

When my parents died, a fundamental, metaphysical sundering between the world and me took place. Lightning had struck twice. The gravity the world had promised – the anchoring of my flights of anxious fancy – had disappeared. The world was now treacherous, lurking with pitfalls, crevasses and trapdoors. The world of misfortune was once dimly glimpsed, its details barely visible, but now I lived in it. I had imagined that with my father’s death, the world had exacted its pound of flesh, a tax so terrible it would be levied only once. But in 14 years, death came calling again. One God – a child’s God, mythical and compassionate – died with my father; another – an adult’s God, a God of reasonableness, the one that ensured this world would not do excessively badly by you – died with my mother.

My parents’ deaths, occupying polar positions on a spectrum of suddenness, infected my life with a persistent dread; they suffused my life with an incurable anxiety, a dread that did not require an identifiable object. Their deaths taught me that this world is ruled by merciless probabilities: there are no warnings attached to daybreak that this might be the day of catastrophic misfortune, of fatal eventuality. In her memoir The Year of Magical Thinking (2007), Joan Didion wrote that recollections of disaster always begin with the mundane nature of the day; the day my father died, the day my mother’s cancer was diagnosed, began as ordinary ones before becoming extraordinary and world-historical. I learned the hard way that there is cause and occasion to fret, to feel anxious, even when there is no indication of disaster. The universe, if not actively malignant, is indifferent to our fates, and cares little for our lives and loves.

Anxiety is insidious, more than just a simple fear. It is, all at once, a fever and an occupation, an affliction and a constitution. An anxiety is a lens through which to view the world, a colouration that grants the sufferer’s experiences their distinctive hue. The Buddha alerted us to a fundamental metaphysical feature of this world, the ‘co-dependent arising’ of all that we experience and know. That is, nothing possesses existence independent of all else that makes it so: an anxious person inhabits a world coloured and contoured by their own, highly individual anxieties; it is a world co-constructed by the sufferer and his or her anxieties. Anxiety is therefore a perspective, a hermeneutical relationship with the world, whose text now gets read in a very peculiar way by this anxiety-laden vision. Things and persons and events fall into focus depending on their interactions with our anxieties: that man in the corner becomes threatening, this chair becomes unstable and unbalanced, that food becomes the agent of a fatal illness, my family – my wife, my daughter – appear as targets for cruel twists of fate. I live in a distinctive world shaded and illuminated by an idiosyncratic anxiety.

I began therapy at 29. During the five years of visits to the clinics that followed – two sessions a week of interpersonal, psychodynamic and Kleinian psychotherapy – I ‘found out’ that I had always been an anxious child, that I had not started being anxious at the time of my father’s death, that in some measure, my anxiety marked me out as a fellow sufferer to all humans. My anxieties had become worse; my parents’ deaths traumatised a subject primed to be so. Their deaths had interrupted a continuum of development in which I would have separated myself from my parents ‘naturally’; as the psychologist Rollo May would have put it, those deaths had threatened values that I held essential to my existence. In the clinic and on the couch, I ‘found out’ that anxiety is fertile, capable of bringing forth newer versions, ever more novel imprints of itself. Prompted by the production of new traumas and losses in our lives, anxieties can interact and recombine like viruses to form newer ‘strains’ that course through us, surprising us with their ferocity and visceral feel. We should not expect our anxieties to remain the same as we age; by paying close attention to their nature, their ‘look and feel’, we can track changes in ourselves and our ‘table of values’.

I learned that I respond with anxiety to this world’s offerings. I’m a better person for this knowledge of myself

Anxiety is not singular; individual anxieties make up a sufferer’s full complement. An anxiety might be a distinctive suite packaged for application to a particular situation of time, place, circumstance and connotation. To know oneself is, very often, an injunction to know one’s anxieties – individually, distinctively – and to know how they change and morph as we do. I have learned, partially, which environments provoke and sustain my anxieties; my future steps are circumscribed by this induced caution. My trajectory through the world is thus informed, at every step, by the anxieties that afflict me.

Anxieties are not immortal. Some die on their own, subdued by exposure to enough recalcitrant facts about the world to make some terrors untenable. Moreover, anxieties are not impervious to relief: sometimes an ‘all will be well’ missive arrives from origins unknown. At that moment, the fog lifts, the burden eases, and an exhilarating giddiness makes its presence felt. The clarity of that moment is intensely pleasurable, so pronounced is the relief from the anxiety’s chafing that had preceded it. The drooping shoulder lifts, there is a slight spring in the step. Caffeine, alcohol and marijuana can induce this effect, a pleasing trait that partially accounts for their perennial popularity across cultures and civilisations. I have flirted with these palliatives, pushing them to the boundaries of their use. But when they ran out, anxiety returned. I then felt a painful, tender nostalgia for the comfort of the ones I love. Thus did I find out how acutely fear of loneliness and abandonment underwrote my anxieties. I abstain from alcohol now, because I cannot handle the anxieties associated with excessive drinking: anxiety was never conquered, it just gave way in the face of a greater one. As Friedrich Nietzsche noted in The Dawn of Day (1881), to master a drive, we need another just as strong, just as needy and demanding. But the ‘victory’ of that drive also informs us of its existence. We might be surprised to find out what else lurks within us.

Sigmund Freud suggested in 1895 that the purpose of therapy was to get us from hysterical misery to common unhappiness, and a key component of that movement is the attention paid to anxiety. Therapy, accordingly, did not comfort or ‘cure’ me. I had hoped to learn that ‘simple’ trauma had caused my anxiety, but instead I learned that anxiety was constitutive of my being: I respond with anxiety to this world’s offerings. I’m a better person for this knowledge of myself.

We are rational animals, but implicit in that rationality is an anxiety. The rational animal remembers and has learned from its past; it anticipates and plans for its future; it modifies its present, anxiously, in response to these memories and anticipations; it is anxious to avoid mistakes, even those it cannot remember and has consigned to the unconscious forgotten. If memory, as John Locke suggested in 1690, is constitutive of our personal identities, then so are our anxieties. The Buddha and David Hume considered the self to be a bundle of ever-changing perceptions and thoughts and images. Similarly, I propose a ‘self-as-bundled-anxieties’ theory: we are a bundle of anxieties; by examining them, to see what vexes us, what makes us anxious, we come to know who we are. Anxiety is a reminder that our selves are rather more diffuse and disorderly than we might imagine, that there are more bits to be seized as they swirl ‘about’ and ‘inside’ us.

Søren Kierkegaard suggested in The Concept of Anxiety (1844) that one of existentialism’s hard-fought rewards – our encounters with true freedom – comes with the terrible burden of encounters with dread and anxiety. This burden, he claimed, was one we should ‘happily’ bear. It is our own cross, and we will find ourselves by our willingness to go forth with it, along the paths of our choosing. Kierkegaard thus enabled an understanding of the value of the most persistent, enduring and subtle of existential responses: unease with the unrealised universe of our lives. There would be little to no anxiety if our lives were mapped out with trajectories and actions articulated for us to follow, with fates and fortunes predetermined and predestined.

Instead, confrontations with existential anxiety take place at the boundaries of each instant of our lives, each experienced as free. Anxiety, Kierkegaard suggests, is present in the movement from possibility to actuality, from the present to the future. Our confrontations with anxiety hold the possibility of self-discovery – what are we capable of, what might we do? Will we have the strength to bear up to the consequences, intended or otherwise, of our actions? To move on with our lives despite the discomfort of these encounters is, for Kierkegaard, the basis of selfhood.

The psychic burden of anxiety is offset by the gains in self-knowledge it affords; to experience anxiety is to experience our self in the making. To allow ourselves to experience anxiety is to engage in a self-observation sensitive to one’s deepest affective responses, alert to the shapelessness of our lives – and our responsibility for mapping our lives anew at every step. This freedom to create ourselves, the subject, is also the vulnerability of the object to which things happen. We dread what we might become, both by our own agency and by the imprint of the world on us.

Our anxieties rush into the mental spaces we leave open, reminding us of all that can go terribly wrong

Perhaps then, anxiety – precisely because it affords a moment for discovery, reconceptualisation and self-construction – should not be medicated out of existence. (Blaise Pascal noted in Penseés (1670) that people employed ‘diversions’ to escape ‘thoughts of themselves’.) Anxiety is, of course, unpleasant, and all too easily triggers the palliative responses of intoxication or medication. So medication might be necessary when anxiety becomes neurotic and crippling – a distinction present in Kierkegaard – but, as May points out, it is an ‘illogical belief’ that mental health consists in being anxiety-free.

Instead, living with the felt experience of anxiety, a conscious ‘wallowing’ and ‘inspection’ can enable an investigation of the self and the particular economy of its lived life. Anxiety, as Kierkegaard claimed, is a ‘school’ for the self. When we meditate, we allow ourselves to feel our anxieties; they rush into the mental spaces we leave open, reminding us of all that can go terribly, terribly wrong; they wash over us, almost making us leap out of our meditative postures. But, there too, while meditating, we can closely inspect the nature of the beast. As Freud might suggest, to medicate anxiety away could indicate a resistance underwritten by fear of finding out who we are. Smashing idols is never easy.

The most significant aspect of Kierkegaard’s suggestion that we pay attention to anxiety is that by noticing it, and talking about it, and acknowledging it, not as pathology but as an informative part of ourselves, it becomes not something to be expelled, but to be welcomed as a message from ourselves. To stop and respond to anxiety’s challenge is to accept dialogue with ourselves. There is a Nietzschean note here: we must display amor fati, a love of fate; we must ‘own’ our anxiety as part of us, to be integrated and deployed to make our lives what we wish them to be. Acceptance of anxiety is the acceptance of the Buddhist Noble Truth that suffering is ever-present in our lives, and to integrate that anxiety into our sense of ourselves is akin to the many therapeutic manoeuvers that the Buddha recommended for us along the Eight-Fold Path of Action and Righteous Duty. It is a movement from being an ‘unskilled’ practitioner of this life’s arts to being a skilled one.

Anxiety taught me the place that death has in my life. Death’s early presence ensured that every loss in my life – migration included – would be coloured by the deadly fear evoked by the most terrible losses of all, those of my parents; nothing has been quite as formative of my philosophical dispositions as those twinned blows. After my mother passed away, a fundamental crisis overcame me: I realised that I was ‘free’ as never before. I had understood my life till then as bound up with my parents. Perhaps I had to aspire to their standards, perhaps I had to seek their approval, perhaps I had to live life less recklessly because of their sensitivities. Now, all such barriers were removed, I was free to ‘do whatever I want, any old time’. I could put myself out of my misery, secure in the knowledge that my parents would not have to grieve the loss of their precious son. This realisation provoked a terror all of its own; it was the first time I experienced true dread, the first time I understood what the existentialists had been getting at.

The upending of this world’s order by my parents’ deaths and my resultant anxiety made me suffer a conceptual shift in my understanding of its workings; it became a philosophical commonplace for me to believe in claims about this world’s malleability through our conscious, emotional, not-entirely rational understanding of it. My parents’ deaths taught me that this world was quicksand built on quicksand, that talk of certainty was laughable, that all things came to be and passed away, that God did not exist, that there were no truths more vital than love, that all we wanted was companionship and spiritual solace. I found myself drawn to philosophical theories that assured me there was no meaning or value to life save the ones we gave it, ones that told me there was no predetermined purpose to my existence. To believe that there was a final end to my life, a purpose, a destination, an intended teleology, was to be infected with an anxiety that I was not fulfilling my purpose in life, that I was ‘wasting’ my life. That anxiety could be relieved only by convincing myself that this life was purposeless, that I could never snatch defeat from the jaws of victory. Curiously enough, this thought was more sustaining than airy directives for how to seek out the Truth about Reality and the Being that underlay it.

My anxiety is intimately related to a hard-won knowledge about this world’s eternally changing nature

These philosophical doctrines provided actual, real psychic relief. By raising the possibility of this life’s meaninglessness, they eased the terrible, anxiety-provoking thought of a pre-existent meaning, value and essence not discoverable or realisable by me. In a world with no ‘wrong’ decisions, there would not be the anxieties of cognitive dissonance either. I realised the therapeutic value of such philosophising and embraced it. My anxious state made me receptive to it; it prepared the intellectual ground by saturating it with an emotional and affective field sustained by an acute anxiety. Philosophy done in this therapeutic fashion is not a shameful state of affairs, it is precisely as it should be: philosophy employed to teach us a better way to live, to dispel those illusions and delusions that make this life harder than it needs to be.

Because of my anxieties, I have come to understand why I’m the philosopher I am, why I hold the views I do, why I do not trust that there is an inherent, essential, meaning or purpose to life. My anxiety is intimately related to a hard-won knowledge about this world’s eternally changing nature, one that often runs afoul of human plans, intentions, attachments or relationships; it informs me that it cannot be so, and it is no less valuable for that as a source of my knowledge. Why privilege some supposedly logical inference over this? Inferences and realisations are prompted by new inputs received, new beliefs formed, new inferences made. We might find ourselves forced toward the conclusion of a train of thought by anxiety, compelling us to move on till we face the truth of that which made us anxious.

My anxieties tell me I’m still capable of feeling. They provide an acute reminder that I’m alive and responsive, and yes, anxious. My anxieties about my family inform me that I have let myself become wrapped up in their selves; they inform me of the boundaries I have formed around and about myself; they inform me of what my self is. They inform me of the risibility of the claim that we are isolated beings whose boundaries terminate at our fingertips, at the surface of our skins. Thus does anxiety inform me of who I am.
