Remember Plato’s Cave allegory? In his Republic he describes a scenario in which some people have spent their lives chained in a cave so they can only see the wall in front of them. There is a fire behind them that casts shadows on the wall that they have no way of knowing are only shadows. For these people, the shadows are their reality. There seem to be many versions of what happens next, but the variation I prefer is that one of the people escapes from the cave and discovers the sun outside for the first time; he realizes that what he had assumed was real -the shadows- were just that: merely the shadows cast by the actual objects themselves.

Sometimes we become so accustomed to seeing things a certain way, we find it difficult, if not impossible, to believe there could be an alternative view. Or assume that, even if there were another version, it must be wrong. But can we be sure that we are evaluating the alternative fairly and without prejudice? Can we assess it with sufficient objectivity to allow a critical analysis? Or are we unavoidably trapped in the prevailing contemporary Weltanschauung? It’s an interesting question to be sure, and one that begs for examination, if only to explore the world behind the mirror.

I stumbled upon an essay by Julie Reshe, a psychoanalyst and philosopher, who, after recovering from a bout of depression, began to wonder whether depression itself was actually the baseline state, and one that allowed a more accurate view of how things actually are:

I have to admit that I had to temporarily divorce myself from my usually optimistic worldview to be able to fathom her argument, and I found it rather uncomfortable. But sometimes it’s instructive -even valuable- to look under a rock.

As a philosopher, Reshe felt the need to examine both sides of an argument critically, putting aside preconceptions and biases. ‘Depressogenic thoughts are unpleasant and even unbearable,’ she writes, ‘but this doesn’t necessarily mean that they are distorted representations of reality. What if reality truly sucks and, while depressed, we lose the very illusions that help us to not realise this? What if, to the contrary, positive thinking represents a biased grasp of reality? … What if it was a collapse of illusions – the collapse of unrealistic thinking – and the glimpse of a reality that actually caused my anxiety? What if, when depressed, we actually perceive reality more accurately? What if both my need to be happy and the demand of psychotherapy to heal depression are based on the same illusion?’ In other words, what if I am actually not a nice person? What if there’s a reason people don’t like me?

Whoa! Suppose this is not a counterfactual? After all, other philosophers have wondered about this. For example, Arthur Schopenhauer whose deeply pessimistic writings about the lack of meaning and purpose of existence I have never understood, or the equally famous German philosopher Martin Heidegger who felt that anxiety was the basic mode of human existence. ‘We mostly live inauthentically in our everyday lives, where we are immersed in everyday tasks, troubles and worries, so that our awareness of the futility and meaninglessness of our existence is silenced by everyday noise… But the authentic life is disclosed only in anxiety.’ My god, where’s my knife?

And even Freud wasn’t optimistic about the outcome of psychotherapeutic treatment, and was ‘reluctant to promise happiness as a result.’ He felt that ‘psychoanalysis could transform hysterical misery into ‘common unhappiness’. Great…

And then, of course, there’s the philosophical tradition called ‘depressive realism’ which holds that ‘reality is always more transparent through a depressed person’s lens.’ And just to add more poison to the cake, ‘the Australian social psychologist Joseph Forgas and colleagues showed that sadness reinforces critical thinking: it helps people reduce judgmental bias, improve attention, increase perseverance, and generally promotes a more skeptical, detailed and attentive thinking style.’

All of which is to say, I suppose, ‘The evolutionary function of depression is to develop analytical thinking mechanisms and to assist in solving complex mental problems. Depressive rumination helps us to concentrate and solve the problems we are ruminating about… depressive rumination is a problemsolving mechanism that draws attention to and promotes analysis of certain problems.’

I have presented these deeply troubling ideas merely as an exercise in perspective, I hasten to add. Sometimes it is valuable to try to grasp the Umwelt of the stranger on the other side of the door before we open it. We can only help if we are willing to understand why they are there.

Part of the solution may lie in puzzling out Reshe’s counterfactuals. She seems to want to assign meaning to her former depression, as have many of the other people she mentions, to buttress her point. She also seems to feel that there was a time when that point of view might have seemed more mainstream. That nowadays there is just too much expectation of happiness -unrealistic expectations by and large, which presents a problem in and of itself. If we constantly expect to achieve a goal, but, like a prairie horizon, it remains temptingly close and yet just out of reach, we are doomed to frustration -a self-fulfilling prophecy.

And yet, it seems to me that resigning oneself to unhappiness, or its cousin depression, doesn’t represent a paradigm shift, but rather a rationalization that it must be the default position -and therefore must serve some useful evolutionary purpose; a position benighted and stigmatized because it advertises the owner’s failure to achieve the goal that others seem to have realized.

I’m certainly not disparaging depression, but neither am I willing to accept that it serves any evolutionary strategy except that of a temporary, albeit necessary harbour until the storm passes. And to suggest that positive emotions -happiness, contentment, joy, or pleasure, to name just a few- however short-lived, are illusory, and unrealistic expectations, is merely to excuse and perhaps justify an approach to depression that isn’t working. A trail that only wanders further into the woods.

I’m certainly cognizant of the fact that there is a spectrum of depressions, from ennui to psychotic and that some are more refractory to resolution than others, but that very fact argues against leaving them to strengthen, lest they progress to an even more untenable and dangerous state.

Perhaps we need to comfort ourselves with the ever-changing, ever-contrasting nature of emotions, and not expect of them a permanence they were likely never evolved to achieve.

Goldilocks, it seems to me, realized something rather profound when she chose the baby bear’s porridge after finding papa bear’s porridge too hot, and mamma bear’s too cold: it was just right…
