Six things... that challenge truth

Ahead of his appearance at Southbank Centre as part of our Belief & Beyond Belief series in September 2017, British philosopher Julian Baggini mused on the notion of truth.


I’m not convinced we live in a post-truth world. But truth is certainly in some kind of trouble, challenged on many fronts. Surprisingly, the sources of several of those challenges are good things.

1. Science

Science is the most efficient truth-generating machine humankind has created. However, such is its power to overturn common sense that its growth has arguably contributed to scepticism that we can ever know the truth at all. Science tells us that the apparently solid objects around us are “really” just collections of particles, which are themselves made up of smaller parts we don’t really understand. Time and space are relative. Today’s orthodoxies are tomorrow’s discredited theories. Science made humanity doubt its own perception of reality and helped sow the seeds for the idea that ultimate truth was beyond us.

2. Liberty

The freedom to think and choose for ourselves is a precious one. However, it has created an exaggerated sense that we are sovereigns of our selves, the sole authors of our lives. The right to a point of view became so sanctified  it became detached from the responsibility to ensure that view is well-grounded. One consequence is that we assert “my truth”, “our truth”, “your truth” as though there were no truth independent of a point of view. But this extremely subjective approach ultimately undermines the whole idea of truth, which if it is to mean anything at all, must involve a recognition of things that are the case whether we perceive them as so or not.

 3. The decline of elites

For most of human history the fates of the many have been in the hands of too few. Elites decided what was best for us, whatever we may think. The forces of democratisation have eroded this privilege. This has been accompanied by a decline of respect for expertise. No longer deferential to the great and the good, we have seen more clearly how experts often get it wrong. However, there is so much we cannot know for ourselves that if we do not defer to experts at all we are left only with our ill-informed hunches and gut feelings. Truth is not a democracy but democratisation has made us less willing to trust those whose expertise can point us to the truth.

4. Globalisation

Our massively interconnected world has brought us closer together and enabled us to understand and celebrate our differences more than ever. It has also exposed our arrogance in believing that “our” way – whoever “we” are – is superior and that we have a monopoly on truth. The moral should have been that we need to consider as many perspectives as possible if we want to get a fuller picture of the truth. Instead, too many have concluded that there are no universal truths, only culturally relative “truths”, none of which is more valid than any other.

5. Psychology

Everyone now “knows” that the conscious, rational mind is not in the driving seat. Unconscious often irrational processes dictate the vast majority of what we do and all the conscious mind does is rationalises it. That’s the message many have taken from the work of psychologists such as Daniel Kahneman and Amos Tversky. It has undermined our confidence in our rationality and with it our capacity to get to the truth. But of course it was only by using reason that these psychologists mapped its limitations clearly. Knowing the limits of conscious rationality should enable us to use it better, not lead us to throw it out.

 6. The free press

Journalists have traditionally seen themselves as discoverers and defenders of the truth. That role is as vital as ever. But in some respects journalism has undermined confidence in the possibility of knowing the truth. Every time a scandal is uncovered it adds to the sense that nothing we are told really is true. At the same time, the less savoury episodes in the history of journalism mean that people don’t necessarily trust newspapers and television channels to tell the truth easily, especially when so many are clearly partisan. An atmosphere of distrust has been created in which suspension of all belief seem preferable to commitment to any truth.

What these six things have in common is that they are all positive developments in human culture than have nonetheless made the possibility of knowing truth – or even of there being a truth to know – seem more difficult than ever. But none should make us doubt that there is any truth there at all, or that it is always beyond us. 

The way forward must start with an acceptance that all six factors show that getting to the truth is difficult and that when we find it, it is often complicated. We should be humble and modest about our ability to know any truths for certain but unless we believe truth is out there and can be discovered, all we have to go on is prejudice, opinion and power.

Being A Man Festival 2016 - Highlights by southbankcentre

Listen to audio highlights of Southbank Centre's Being a Man festival 2016 including Professor Green, Roger Moore, Grayson Perry and Ashley Walters plus topical debates covering subjects from male suicide and paternity to gaming.

Being a man in the 21st century to me, is to be someone that feels good in his skin, that takes care of himself and the people around him, that is capable of love - because yes, men do have feelings too - and is not ashamed of himself. He is what he wants to be; himself.

Science Versus Religion: Do We Need to Choose? – Saturday Day Pass

How soon is now?

‘I saw huge buildings rise up faint and fair, and pass like dreams…’ 

In 1895, the writer HG Wells imagined a time traveller’s journey through the fourth dimension, thousands of years into the future of London. He returns to tell a tale of fantastic landscapes, androgynous people and a society both horrifying, and mysteriously familiar.  

Through visions of society and technology, the future of gender and the changing natural world, yesterday’s science fiction provides strange hints of today’s realities. This year, our London Literature Festival investigates groundbreaking literature and asks writers and thinkers to imagine the future from the perspective of our rapidly changing times.

Margaret Atwood

Which idea about the future proposed in your fiction would you posit as the most likely to come true? 

Many are equally horrible, but it seems as if the use of the blood of young people to rejuvenate rich older people – as posited in The Heart Goes Last – is already in process.

Richard Dawkins

What are your fears and hopes for the future?

My hope is that we will increasingly govern humanity’s affairs by reason, based on objectively and publicly verifiable evidence. My fear is that this will not happen and that superstition, religion and prejudice will continue to plague the world.

Etgar Keret


I think that the greatest challenge was and will always be to serve as an interface between a child and a world that often makes very little sense. Technology may advance but human behavior will stay unpredictable and often difficult to explain.

What are your fears and hopes for the future? 

My fear is that we miss the opportunity to act as a cohesive global society to address the environmental challenges we face and end up in a situation in which a small population thrives but many struggle in poverty. My hope is that instead we face up to the crises ... and negotiate a way to share the world’s resources.

Thomas Thwaites

How do you think human relationships with other species will change in the years to come?

I think that the non-human animal rights project will succeed in its mission to see some animals granted some of the rights of humans… I’m interested in the idea of victimless meat: growing meat in vats rather than rearing a whole sentient being just so we can eventually eat its muscles.

Nikesh Shukla

What will immigration look like 50 years from now?

It could go two ways. One way: Britain embraces the whole ‘no man is an island but Great Britain is so piss off foreigners’ ethos. And that’s it... what does Britain have to offer then? Or it could go that Britain realises what good work is being done in the cities, in London, Bristol, Manchester and Birmingham, that it has an outward-facing attitude to the world ... and it’ll thrive because people love our big dumb accents. I don’t know. Can you tell I don’t feel hopeful? 

Lauren Beukes


I hope more men will figure out a meaningful way of being in the world, stepping away from the ridiculous and destructive ideals society holds them to, that we are complicit in, that masculinity is tough and savage, that they must be the providers and protectors ... and that anything less is a humiliation. Because that sense of powerlessness, that humiliation, fear and ego, drives domestic violence and homophobia, and kills compassion.
