Sleep and the Meaning of Life: Fernando Pessoa on the Existential Dimension of the Horizontal Hours

One of the most important things I have learned about living is that, in any life of purpose and creative vitality, you must be as religious and disciplined about your sleep as about your work. And yet one of the great self-betrayals of our culture is the way it wears the lack of sleep as a badge of honor on the lapel of the ego of achievement — the cult of productivity gone past the sacrifice of presence, sacrificing even that precious nightly absence of conscious thought and metabolic urgency necessary to recover, to reset, to recalibrate so that we may begin again, in the deepest sense, in the new day. Trouble sleeping both troubles living and signals a troubled life — because sleep is how most of the body’s physical systems recover; because, ever since evolution invented REM in the bird brain, it has been helping us regulate our negative emotions; because sleep goes beyond the physical, the mental, and the emotional to touch the existential. No one has written more passionately or more perceptively about that existential dimension of sleep than the Portuguese poet and philosopher Fernando Pessoa (June 13, 1888–November 30, 1935) throughout The Book of Disquiet (public library) — the posthumously published masterpiece that also gave us Pessoa on how to be a good explorer in the lifelong expedition to yourself, the trouble with love, and how to unself into who you really are. Pessoa recognizes that, more than a biological impediment, all those unsolved disquietudes and subtle estrangements from ourselves that keep the eyelids from closing the curtain on the day are emissaries of our existential angst. Wrestling with his own, he writes: I’m going to life’s bed wide awake, unaccompanied and without peace, in the ebb and flow of my confused consciousness, like two tides in the black night where the destinies of nostalgia and desolation meet. While Kafka is reverencing the creative power of insomnia a dozen degrees of latitude north, Pessoa discovers in his sleeplessness a strange metaphysical power: The clock in the back of the deserted house (everyone’s sleeping) slowly lets the clear quadruple sound of four o’clock in the morning fall. I still haven’t fallen asleep, and I don’t expect to. There’s nothing on my mind to keep me from sleeping and no physical pain to prevent me from relaxing, but the dull silence of my strange body just lies there in the darkness, made even more desolate by the feeble moonlight of the street lamps. I’m so sleepy I can’t even think, so sleepless I can’t feel. Everything around me is the naked, abstract universe, consisting of nocturnal negations. Divided between tired and restless, I succeed in touching — with the awareness of my body — a metaphysical knowledge of the mystery of things.

The portal into that mystery, Pessoa realizes, is the cessation of selfing that marks waking life: To cease, to sleep, to replace this intermittent consciousness with better, melancholy things, whispered in secret to someone who doesn’t know me! … To cease, to be the ebb and flow of a vast sea, fluidly skirting real shores, on a night in which one really sleeps! … To cease, to be unknown and external, a swaying of branches in distant rows of trees, a gentle falling of leaves, their sound noted more than their fall, the ocean spray of far-off fountains, and all the uncertainty of parks at night, lost in endless tangles, natural labyrinths of darkness! … To cease, to end at last, but surviving as something else: the page of a book, a tuft of dishevelled hair, the quiver of the creeping plant next to a half-open window, the irrelevant footsteps in the gravel of the bend, the last smoke to rise from the village going to sleep, the wagoner’s whip left on the early morning roadside… Absurdity, confusion, oblivion — everything that isn’t life… Behind me, on the other side of where I’m lying down, the silence of the house touches infinity.
