Some of the stars of this year’s Glastonbury festival have joined the chorus of campaigners denouncing ‘throwaway fashion’. They’ve given some of their own clothing to Oxfam and are encouraging their fans to buy their outfits second-hand (or ‘pre-cherished’). These days you can buy a dress for a fiver and wear it once before chucking it away. Is that proof that capitalism has gone too far? Critics of the industry cite the appalling conditions and rates of pay in the third-world factories churning out garments that will end up as non-biodegradable landfill quicker than you can say “sustainability”. There are those, on the other hand, who prefer not to be lectured by celebs famous for their multiple costume changes and who point out that the minimum wage doesn’t run to a wardrobe of high-quality clobber. Beyond the social and environmental implications of fast fashion, what about the moral value of clothes themselves? We humans have covered our nakedness ever since Adam and Eve embarrassed themselves in the Garden of Eden. Fashion lovers say that our clothes matter because they are expressions of an aesthetic sensibility, intrinsic to both self-esteem and dignity. Others believe the fuss about this season’s ‘look’ is a cynical manipulation of insecurity and a celebration of vanity and superficiality. The morality of fashion: fashionably moral.

Famously photographed stuck on a zipwire, Boris Johnson is now attempting the tightrope. Unless he falls off, the pollsters suggest, he will alight in four weeks’ time in Downing Street. Perhaps understandably, he is trying to limit the number of buffetings to which he subjects himself in the meantime. Buffetings, however, continue. While it may be fascinating to voyeurs that he apparently spilled wine on a sofa and had a crockery-smashing row with his partner, is that really important? The Boris backers said this was politically-motivated, Corbynista curtain-twitching. The neighbours defended their actions, saying they recorded the proceedings out of genuine concern and passed the audio to The Guardian in the public interest. But was it? How much, if anything, do we have a right to know about a domestic quarrel involving a potential PM? How, indeed, should we balance the competing rights of public figures to a private life and of citizens to know about those in power over them? What about the value we place in moral character itself? It could be argued that honesty in small things is no small thing – as Abraham Lincoln said: “I am not bound to win, but I am bound to be true”. These days however, politicians should be judged, many insist, not on the content of their character, but on the merits of their manifestos. Yet, paradoxically, it has become a commonplace of Twitter that political foes are attacked not for having bad ideas but for being thoroughly bad people. So what is the relationship between virtue and effectiveness? Is the requirement for moral character in politicians overrated or overdue?

Comedy is a serious business, as Jo Brand discovered when she made a joke about throwing battery acid at politicians. The police have now dropped their investigation into her and she has not been sacked by the BBC – unlike Danny Baker after his apparently ‘racist’ tweet last month. Guardians of free speech worry about the policing of humour and the erosion of the right to offend. Yet we live in politically-febrile times and a joke may provoke more than mere amusement or even offence. Jokes can be deemed to trivialise political violence, encourage hatred and excuse rape. With that in mind, do comedians have a social responsibility to rein themselves in, even if they believe they’re ‘punching up’, not ‘punching down’? Or should they follow their comedic instinct when it’s telling them to let rip? After all, humour is by nature subversive and, from Martin Luther to Mock The Week, it has always been an important part of political discourse. Beyond politics, where should we draw the line on funny lines? It could be argued that a joke becomes unacceptable when it dehumanises minorities or incites violence. Yet aren’t these criteria themselves subjective? Context and tone are everything in comedy but they’re fiendishly difficult to define. Does it matter that the intent behind a gag is benign if the consequences of telling it are harmful?

Discussion of the Tory leadership race has shifted from questions of policy to issues of personal morality. Given that most of the candidates have admitted – to a greater or lesser extent – snorting, smoking or supping illegal substances at some point in the past, how thunderously should they be condemned? Shouldn’t people running for high office be blasted for their past ‘indiscretions’? Isn’t it right that any person in a position of privilege and authority who has shown a contempt for the law should suffer the consequences? Or should we worry that our 21st century witch-finders have developed an unhealthy obsession with ‘offence archaeology’ – the diligent digging-up of an historic misdemeanour and using it as a basis upon which to judge a person’s entire character? It’s been asserted that even worse than the crime itself is the sin of hypocrisy. An article from 1999 has been republished in which Michael Gove criticised "middle class professionals" who took drugs, at the same time that he himself was taking cocaine. He has defended himself against headlines calling him a hypocrite, saying: “If any of us lapse sometimes from standards that we uphold, that is human.” Hypocrisy is an easy accusation to hurl but a tricky sin to understand - La Rochefoucauld famously called it “a tribute vice pays to virtue". Our own moral boundaries are so often flexible, yet psychologists suggest we’re less inclined to give others the ethical wiggle room we might afford ourselves. So should we have more humility to look inward before judging others? Or is it a moral cop-out simply to say, “Let the person who is without sin cast the first stone”?

The Allied invasion of Normandy, 75 years ago, was the biggest land, air and naval operation in history. It led to the liberation of Europe from Nazi control and was the galvanising moment of the age, but it came at a cost that is almost unimaginable: at least 2,700 British soldiers, sailors and airmen lost their lives in the first 24 hours. Their sacrifice ensured that later generations would enjoy a lifetime of peace in Europe. Very few people in Britain today, other than military professionals, have ever worried about having to fight a war. Does that collective comfort also mean that we would be incapable of answering the same call? It is instructive to consider how society has changed in 75 years of peacetime - in particular our loss of deference. Some say that’s a good thing; it empowers us to stand up to institutions on behalf of the marginalised and the oppressed. Others, however, lament the erosion of the national virtues – duty, self-sacrifice, respect for our leaders – that made D-Day possible. As the author David Brooks put it, we’ve moved as a society from “We’re all in this together” to “I’m free to be myself”. And what of the nature of warfare itself? In 1944, though the cost to human life was enormous, it was a straightforward fight with a uniformed enemy led by villains. Conversely, modern, surgical warfare kills fewer people but is more remote and, according to its critics, further blurs the distinction between soldiers and civilians. What does D-Day teach us about how we might judge ourselves morally against our forebears?

The Sackler Trust has suspended new charitable donations in the UK, following claims that the Sackler family billions are linked to the opioid crisis in the US. The family denies the allegations, but both the National Portrait Gallery and the Tate group have refused its money. Whether that money is tainted or not (the question is hotly disputed) the controversy raises important questions about the ethics of funding for the arts, sport and philanthropic charities. Purists believe that good causes should always refuse money from bad sources, no matter how much potential benefit that money could bring. More grateful recipients hold their begging bowl with one hand and their nose with the other, insisting that there is no such thing as dirty money because a coin is morally neutral; whatever real, perceived or alleged crimes may have been committed to earn it should not rest on the conscience of the recipient. How should we view this quest for moral purity? It does appear that society is becoming increasingly intolerant of moral grey areas. It’s a short step from turning down dodgy donors to ‘no platforming’ those with unfashionable opinions. Perhaps that’s a good thing, an inspiring translation of principles into action predicated on equality and justice for all. Or perhaps such thinking is a new form of secular puritanism which is intolerant and dangerous. When does the enforcement of moral principles make us better? When does the attempt to resist moral pollution become its own form of rules-based bigotry?

Brexit is only days away and we still don’t have a plan. This is enraging for many, perplexing for most, and amusing for those who like their humour black. As one current slogan observes, “even Baldrick had a plan”. Some argue we are locked in a crisis of leadership. The major parties are fragmenting, collective cabinet responsibility has been trashed and the political atmosphere in parts of Britain is toxic. Have the two main party leaders ever been as weak? Many voters can’t understand how Parliament has so dismally failed to follow a simple instruction, and why the political class has flunked collective moral leadership. Kinder observers point out that the task facing MPs was anything but simple, and explain that while politics is working exactly as it should, the chaos in Parliament reflects an electorate with a split personality. So, with all this in mind, what sort of commanders-in-chief do we need now, in politics and beyond? Visionaries? Listeners? Pragmatists? Power-watchers have reported a sea change in recent years: many leaders now spend more time trying to please their rank and file, they say, and less time actually leading. There was a time when leaders were prepared to defy their supporters for “the greater good of all”. That sounds persuasive unless you think it was the top-down, managerial style of leadership that contributed to people’s sense of political alienation in the first place. Do leaders like Churchill, Thatcher, Blair and May define their eras or do the events of different eras determine the leaders? Do we always get the leaders we deserve?

The rise in the number of fatal stabbings in recent months has generated big headlines and heated political debate. Teenage knife crime is high on the national agenda. There is broad agreement that something has to change but not as much agreement about what that is. Should there be more police officers on the streets? more surrender bins? more use of stop and search? more weapons sweeps? tougher sentences? Do we need a knife crime ‘tsar’ to co-ordinate it all? What about the role of schools and youth clubs? But before we start writing policy prescriptions, let’s ask a more basic question: are we seeing a long-overdue response to a desperate and tragic situation, or a nation in the grip of full-blown moral panic? The phrase ‘moral panic’ - which was popularised by sociologist Stanley Cohen in his 1972 book about mods and rockers - is nearly always used pejoratively to denote an over-the-top expression of public anxiety about the lowering of moral standards. Yet it could be argued that a moral panic is like a whistling kettle - it’s a warning that things have come to the boil. Perhaps we shouldn’t speak of moral panics but of moral calls to action – opportunities to get money spent and policies reformed on important issues that are usually below the national radar. Or perhaps such societal soul-searchings are just spasms of empathy, emotional outbursts that take no account of long-term trends, get in the way of clear-eyed policy-making and divert resources from duller but worthier causes. Are moral panics good for society?

“Leaving Neverland”, a two-part TV documentary broadcast this week, details child sex abuse claims against Michael Jackson. The renewed allegations have prompted a debate about whether we should stop listening to his music. Some believe a boycott takes an important moral stand against the late singer’s alleged crimes. To pay any such artist the compliment of our appreciation, they say, is to undermine the victims. Others think the moral character of the artist has no bearing on the worth of the art. In his essay ‘The Death of the Author’, the French literary critic Roland Barthes argues that a book and its creator are entirely unrelated. Is he right? Does a work of art have intrinsic moral value? Or should we reappraise certain works in light of the questionable behaviour and beliefs of the cultural figures that created them? Charles Dickens, who has a worldwide reputation as a compassionate moralist, was also (according to recently-unearthed letters) a ruthless husband who tried to have his wife locked up in a lunatic asylum because "she had outgrown his liking.” Should we judge any public figures (now or in the past) by their private lives and prejudices, or should we rate them instead on their competence and achievements?

At the end of a landmark Vatican summit on paedophilia in the Catholic Church, Pope Francis had strong words for guilty clergy, describing them as "tools of Satan." Campaigners, though, are looking for the devil in the detail of the Pope’s proposals. Some of them are saying that the Church has now simply lost its claim to moral authority. Has it? Or, in our understandable revulsion to this scandal, do we risk overlooking what institutional religion might still have to offer? The loss of trust in institutions is also part of a wider cultural story that’s been playing out in the West for nearly a century, and that’s the story of the decline of obedience. For many, this is something to be celebrated, a recognition of the dignity of the individual, the primacy of personal sovereignty. For others, it has created a moral relativism that is making people more self-absorbed and selfish, and that will tear society apart. Cardinal John Henry Newman (who is about to be canonised) once said: "I shall drink … to Conscience first, and to the Pope afterwards." Should we have a duty to anything other than our own conscience? If so, what else should demand a claim on our obedience? Many who applaud the civil disobedience of school pupils leaving lessons to join climate protests are appalled by the rise of recreational drug-taking, yet both are acts of rebellion. Individual disobedience can be harmful to ourselves and others, but mass disobedience can change the world. Does our culture value obedience too highly, or not highly enough?
