Can Thought Experiments Solve Ethical Dilemmas?


In ethics, the appeal to expand the “moral circle” typically requires moving from consideration of yourself to that of all of nature.

By Keith Tidman

What, in ethical terms, do we owe others, especially when lives are at stake? This is the crux of the ‘Drowning Child’ thought experiment posed by the contemporary philosopher, Peter Singer.

Singer illustrates the question to his students in this way:

You are walking to class when you spot a child drowning in a campus pond. You know nothing of the child’s life; and there is no personal affiliation. The pond is shallow, so it would be easy to wade in and rescue her. You would not endanger yourself, or anyone else, by going into the water and pulling the child out.
But, he adds, there are two catches. One is that your clothes will become saturated, caked in mud, and possibly ruined. The other is that taking the time to go back to your dorm to dry off and change clothes will mean missing the class you were crossing the campus for.

Singer then asks his students, ‘Do you have an obligation to rescue the child?’

The students, without exception and as one might expect, think that they do. The circumstances seem simple. Including that events are just yards away. The students, unprompted, recognise their direct responsibility to save the flailing child. The students’ moral, and even pragmatic, calculus is that the life of the child outweighs the possibility of ruined clothes and a missed class. And, for that matter, possibly the sheer ‘nuisance’ of it all. To the students, there is no ambiguity; the moral obligation is obvious; the costs, even to the cash-strapped students, are trivial.

The students’ answer to the hypothetical about saving a drowning child, as framed above, is straightforward — a one-off situation, perhaps, whose altruistic consequences end upon saving the drowning child who is then safe with family. But ought the situation be so narrowly prescribed? After all, as the stakes are raised, the moral issues, including the range of consequences, arguably become more ambiguous, nuanced, and soul-searching.

At this point, let’s pivot away from Singer’s students and toward the rest of us more generally. In pivoting, let’s also switch situations.

Suppose you are walking on the grounds of a ritzy hotel, to celebrate your fiftieth anniversary in a lavish rented ballroom, where many guests gleefully await you. Because of the once-in-a-lifetime situation, you’re wearing an expensive suit, have a wallet filled with several one-hundred-dollar bills, and are wearing a family legacy watch that you rarely wear.
Plainly, the stakes, at least in terms of potential material sacrifices, are much higher than in the first scenario.

If, then, you spot a child drowning in the hotel’s shallow pond nearby, would you wade in and save the child? Even if the expensive suit will be ruined, the paper money will fall apart from saturation, the family antique watch will not be repairable, and the long-planned event will have to be canceled, disappointing the many guests who expectantly flew in at significant expense?

 

The answer to ‘Do you have an obligation to rescue the child?’ is probably still a resounding yes — at least, let’s hope, for most of us. The moral calculus arguably doesn’t change, even if what materially is at risk for you and others does intensify. Sure, there may be momentary hesitation because of the costlier circumstances. Self-interests may marginally intrude, perhaps causing a pause to see if someone else might jump in instead. But hesitation is likely quickly set aside as altruistic and humanitarian instincts kick in.

To ratchet up the circumstances further, Singer turns to a child starving in an impoverished village, in a faraway country whose resources are insufficient to sustain its population, many of whom live in wretched conditions. Taking moral action to give that child a chance to survive, through a donation, would still be within most people’s finances in the developed world, including the person about to celebrate his anniversary. However, there are two obvious catches: one is that the child is far off, in an unfamiliar land; the other is that remoteness makes it easier to avert eyes and ears, in an effort at psychological detachment.

We might further equivocate based on other grounds, as we search for differentiators that may morally justify not donating to save the starving child abroad, after all. Platitudinous rationales might enter our thinking, such as the presence of local government corruption, the excessive administrative costs of charities, or the bigger, systemic problem of over-population needing to be solved first. Intended to trick and assuage our consciences, and repress urges to help.

Strapped for money and consumed by tuition debt, Singer’s students likely won’t be able to afford donating much, if anything, toward the welfare of the faraway starving child. Circumstances matter, like the inaccessibility; there’s therefore seemingly less of a moral imperative. However, the wealthier individual celebrating his anniversary arguably has a commensurately higher moral obligation to donate, despite the remoteness. A donation equal, let’s say, to the expense of the suit, money, and watch that would be ruined in saving the child in the hotel pond.

So, ought we donate? Would we donate? Even if there might appear to be a gnawing conflict between the morality of altruism and the hard-to-ignore sense of ostensible pointlessness in light of the systemic conditions in the country that perpetuate widespread childhood starvation? Under those circumstances, how might we calculate ‘effective altruism’, combining the empathy felt and the odds of meaningful utilitarian outcomes?

After all, what we ought to do and how we act based on what’s morally right not infrequently diverge. Even when we are confronted with stark images on television, social media, and newspapers of the distended stomachs of toddlers, with flies hovering around their eyes.

For most people, the cost of a donation to save the starving child far away is reasonable and socially just. But the concept of social justice might seem nebulous as we hurry on in the clamour of our daily lives. We don’t necessarily equate, in our minds, saving the drowning child with saving the starving child; moral dissonance might influence choices.

To summarise, Singer presented the ethical calculus in all these situations this way: ‘If it is within our power to prevent something bad from happening, without sacrificing anything of comparable moral importance, we ought, morally, to do it’. Including saving the life of a stranger to avoid a child’s preventable death.

For someone like the financially comfortable anniversary celebrator — if not for the financially struggling college students, who would nevertheless feel morally responsible for saving the child drowning on campus — there’s an equally direct line of responsibility in donating to support the starving child far away. Both situations entail moral imperatives in their own fashion, though again circumstances matter.

The important core of these ethical expectations is the idea of ‘cosmopolitanism’: simply, to value everyone equally, as citizens of the world. Idealistic, yes; but in the context of personal moral responsibility, there’s an obligation to the welfare of others, even strangers, and to treat human life reverentially. Humanitarianism and the ‘common good’ writ large, we suppose.

To this critical point, Singer directs us to the political theorist William Lecky, who wrote of an ‘expanding circle of concern’. It is a circle that starts with the individual and family, and then widens to encompass ‘a class, then a nation, then a coalition of nations, then all humanity’. A circle that is a reflection of our rapid globalisation.

Perhaps, the ‘Drowning Child’ thought experiment exposes divides between how we hypothesize about doing right and actually doing right, and the ambiguity surrounding the consistency of moral decision-making.

Mathematical Meditations

by Thomas Scarborough

I shall call this post an exploration—a survey. Is mathematics, as Galileo Galilei described it, ‘the language in which God has written the universe’? Are the numerical features of the world, in the words of the authors of the Collins Dictionary of Philosophy, Godfrey Vesey and Paul Foulkes, ‘free from the inaccuracies we meet in other fields'? Many would say yes—however, there are things which give us pause for thought.

  • Sometimes reality may be too complex for our mathematics to apply. It is impossible to calculate in advance something as simple as the trail of a snail on a wall. Stephen Hawking noted, 'Even if we do achieve a complete unified theory, we shall not be able to make detailed predictions in any but the simplest situations.' If we do try to do so, therefore, we abuse mathematics—or perhaps we should say, in many contexts, mathematics fails. 
  • Our measurement of the world may be inadequate to the task—in varying degrees. I take a ruler, and draw a line precisely 100 mm in length. But now I notice the grain of the paper, that my pencil mark is indistinct, and that the ruler's notches are crude. In many cases, mathematics is not the finest fit with the reality we deal with. In some cases, no fit at all. I measure the position of a particle, only to find that theoretical physicist Werner Heisenberg was right: I have lost its velocity. 
  • The cosmologist Rodney Holder notes that, with regard to numbers—all numbers—'a finite number of decimal places constitutes an error'. Owners of early Sinclair calculators, such as myself, viewed the propagation of errors in these devices with astonishment. While calculators are now much refined, the problem is still there, and always will be. This error, writes Holder, 'propagates so rapidly that prediction is impossible'. 
  • In 1931, the mathematician Kurt Gödel presented his incompleteness theorems. Numbers systems, he showed, have limits of provability. We cannot unite what is provable with what is true—given that what this really means is, in the words of Natalie Wolchover, ‘ill-understood’. A better known consequence of this is that no program can find all the viruses on one’s computer. Consider also that no system in itself can prove one’s own veracity. 
  • Then, it is we ourselves who decide what makes up each unit of mathematics. A unit may be one atom, one litre of water, or one summer. But it is not that simple. Albert Einstein noted that a unit 'singles out a complex from nature'. Units may represent clouds with noses, ants which fall off a wall, names which start with a 'J', and so on. How suitable are our units, in each case, for manipulation with mathematics?
  • Worst of all, there are always things which lie beyond our equations. Whenever we scope a system, in the words of philosophy professor Simon Blackburn, there is 'the selection of particular facts as the essential ones'. We must first define a system’s boundaries. We must choose what it will include and what not.  This is practically impossible, for the reason that, in the words of Thomas Berry, an Earth historian, 'nothing is completely itself without everything else'. 
  • I shall add, myself, a 'post-Gödelian' theorem. Any and every mathematical equation assumes that it represents totality. In the simple equation x + y = z, there is nothing beyond z. As human beings, we can see that many things lie outside z, but if the equation could speak, it would know nothing of it. z revolts against the world, because the equation assumes a unitary result, which treats itself as the whole.
Certainly, we can calculate things with such stunning accuracy today that we can send a probe to land on a distant planet’s moon (Titan), to send back moving pictures. We have done even more wonderful things since, with ever increasing precision. Yet still the equations occupy their own totality. Everything else is banished. At what cost?

Picture Post #70: Civilisation!



'Because things don’t appear to be the known thing; they aren’t what they seemed to be
neither will they become what they might appear to become.'

Rooftop Madrid. 2021. 

The last two picture posts did regard a certain idea of decay, and as a threesome, this picture might enhance that subtle fascination that surrounds those layered surfaces.

The abstract has often been criticized as either easy art or difficult thinking. Even when we became used to abstract ideas and turned them into what is called: rational thinking. Do we not mostly accept what is convenient in some way or other, no matter how illusory things are, and all the rest we prefer to discard? 

We overlap thoughts with actions and emotions; overlapping is our strength and our misery. Continuous overlapping sketches the picture we live in, and so, rather unawares, we shake a cocktail that we define as ‘our life’. 

What we can apprehend simply by viewing even trash, so complicated by its nature for refuse(d), and often wished unseen, is that everything traces into something else, and transforms. 

Symbolically, when we look at ourselves, we might find a trashy landscape far worse than this rooftop. Although the terror of seeing the veritable junkyard from within also shows the many forgotten things that we touched and related to during our life. And we’re all that, not just a part. 

The picture we prefer to see cannot match the reality we imagine. How real can we truly be?

Looking Backward, Looking Forward

by Allister Marran

Who here thinks that life today will be what life is like in 20 years, or 50 or 100?

I mean, when I was born in 1976 there was no such thing as television in South Africa. That came later that year, with a measly one channel and a broadcast time of a couple of hours a day. And it was introduced as another propaganda arm of the apartheid government, carefully orchestrated to feed misinformation to those fortunate enough to afford one, which coincidentally was their target market.

Nobody came home from work or school back then and parked off in front of a 75 inch box with 1000 streaming channels at the ready. Life was vastly, fundamentally different.

Board games, visiting friends for coffee, swimming, clubs, dinner parties, cricket and soccer and four square in the road, reading and collecting and creating. People did stuff.

In 1982 I got my first computer for Christmas, a ZX Spectrum with 48k ram. It was mind blowing what it could do. My life irrevocably changed, the future had arrived and I was a part of it. And it was good.

I sat I front of that computer and learned the ins and outs of basic programming, and I played games. Boy did I play a lot of games. I was hooked.

As processing power increased exponentially so did graphics and game logic, and soon the game worlds were massively immersive, 2D became 3D, polygons became textured and colour pallettes went from 8 colour to 16 million colours in a matter of a few short years. It was glorious.

In the mid 90s I got my first mobile phone, an Ericsson 628 with a single line of display text. It was like a mini PDA like those Tricorder things they carry on Star Trek, or so it felt to me. 

A year or so later the internet came into our homes. Email, webpages and rudimentary forms of social media like bulletin boards, IRC and later instant chat hubs and comment sections on web based message boards.

The world was connected in every way. You no longer had to get out the house, you had a phone in your pocket, you could chat to your mates while.sitting in your study on your PC, you could download episodes of your favorite shows and watch them. And a new thing was on the horizon, you could even shop online for books and later groceries too. Soon you would never have to go out ever again.

The last puzzle piece was the smart phone in 2008 or so. A single device that drew it all together, your PC and tablet and gaming and television and phone and social media and alarm clock and watch and camera and video recorder and file server and banking and weather forecast and news source and calendar and email and GPS all in one place, on one device.

We can marvel at how in 45 years we have progressed from the first TV shows to a super computer in your pocket. And indeed, it's an engineering feat of incredible proportions. 

But is the world better for it?

In a world where people would visit friends and neighbors instead of turn on the telly, in a world where people would go for a run with a mate instead of spending an hour or two on Fortnite, in a world where people were not constantly bombarded with anxiety causing social media hysteria and toxic crazies yelling about the end times because of government over-reach and scaring the crap out of you every day, maybe the simple times without technology were indeed the good old days.

People certainly seemed happier back then.

The world will continue to change, it has to. It's called progress. More new things will come to be in the next 45 years, and your kids who are young today will lament their lot in life and yearn for the simpler times of 2021 when things were easier, when they only had to deal with an iPhone screen and a bit of harmless social media pressure.

Never lose sight of what is truly important in this world, things that have stayed constant throughout the ages, regardless of technological advances and social upheaval.

Treasure friends and family. Seek out and promote honesty and righteousness. Gravitate towards love and caring. Never lose site of your morals, your values and your God. Fight the good fight.

Don't let them grind you down.

We live in 2021. It's a scary place, full of screens and bots and AI's and algorithms.
But our souls can still hark back to that day before it all changed back in 1976, before that test pattern brought the future into our homes.

Change will always affect your life, but don't let it define who you are.
