Philosophers Asleep

It is easy to see why philosophers have, on the whole, avoided talking about sleep. Those who see the aim of philosophy as being to cultivate the most unpeeled mode of wakefulness are likely to treat sleep as an enemy. Hypnophobia was a striking theme in Existentialist thought. “Blessed are the sleepy ones” Nietzsche said sarcastically, “for they shall soon drop off.” And he sometimes endeavoured to do without sleep, on one occasion trying to live on four hours sleep a night for a fortnight. (I read this unimpressed when I was a junior doctor in the 1970s, and my 104-hour-week included periods of up to 48 hours continuously on call.) Jean-Paul Sartre’s Antoine Roquentin, the anti-hero of Sartre’s Nausea (1938), expresses his contempt for the landlord of the café he frequents by observing that “when this man is alone, he falls asleep.” And a character in one of his other novels observes with horror the person opposite him on the train, fast asleep, passively swaying in time to the movement of the carriage, reduced to a material object. This continuation of our lives in the absence of our waking self, in which the living daylights are replaced by the half-living nightlights, is a creepy reminder of the unchosen automatisms upon which our chosen lives depend.

Not only is sleep a reminder of our ultimate helplessness, or even of how circumscribed a place thought sometimes plays in our lives, there is also the fear of contagion, as if talking about sleep might induce it – just as this reference to yawning will get at least 50% of you yawning in the next 15 minutes. (It’s a fact, honest!)

Of course, there is no reason why the mind should not think about its antithesis, nor why super-mindful philosophers should not take an interest in our regular spells of compulsory mindlessness. After all, physicists have devoted much of their extraordinarily brilliant intellectual exertions to clarifying the nature of matter – of what is there, stripped of the kinds of meanings that fill their own consciousnesses. Philosophers, however, have a particular fear of one kind of sleep: the sleep that their own works may induce. Those carefully crafted arguments, the painstakingly revised sentences, expressing insights, so they hope, into the most fundamental aspects of the world, seem less able than a strip cartoon or a gossip column to hold back the reader from a world-dissolving snooze. Honest philosophers know they cannot complain about casting their philosophical pearls before drowsy swine, because they, too, have fallen asleep over the works of philosophers greater than themselves. I speak as a minor player who has sometimes dozed off while reading Heidegger’s Being and Time – possibly the greatest philosophical work of the last century, and the subject of a monograph I published a decade ago, and over which others too have dozed off. On other occasions I have woken with a start to discover that Kant’s Critique of Pure Reason has fallen from my slackening hand. There could be no more profound critique of reason, pure or impure.

For Descartes, cessation of thinking meant ceasing to be an ‘I’, so thoughtless sleep was vexing indeed – a vegetable, organic gap in our spiritual life. As James Hill (to whom I owe most of the contents of this paragraph) pointed out in ‘The Philosophy of Sleep: Descartes, Locke and Leibniz’ (in The Richmond Journal of Philosophy, Spring 2004), Descartes’ view of the mind as a substance did not allow for any pause in the continuity of thought. If the mind were the kind of thing that could be extinguished by the sound of a lecturer’s voice and rekindled by a wet flannel, it would not be worthy of the status of a substance, which should be immune from mere accidents. Descartes therefore concluded that we never stop thinking, even in the deepest sleep; however, in our deepest sleep we do not lay down any memories of our thoughts. Ad hoc or what?

John Locke would have none of it. Empirical evidence, he says, tells us that we do not think when asleep, and that’s the end of the story: “every drowsy Nod shakes [the Cartesian] Doctrine.” Leibniz, anticipating the confusions of Herr Professor Freud, argued that Descartes was right: we are thinking during dreamless sleep, but our thoughts are unconscious – rather like the perceptions we have without noticing them. I leave the reader to referee the discussion, but its unsatisfactory nature offers another reason why most philosophers have shied away from sleep.

  4. The author seems to want to further the philosophical discussions of sleep, despite it being relatively historically neglected. There seems to be no agreed upon philosophies of sleep.

  5. Sleep has always been a tough subject for history’s famous philosophers. Some have even been out right hostile towards the idea of it. The state of oblivion and helplessness that accompanies this state of consciousness unsettles even the most learned men, perhaps due to their own inevitable submission to its will. The lack of thought, or at least the lack of awareness of thought, makes sleep unlikely to be deciphered by philosophical inquiry any time soon.
