Why are so many statues naked? – Artie, age 12, Astoria, New York

We are all born naked, and sculptures of the human body in its natural state are as old as humankind.

In the history of art, nudity does not have just one meaning; it can express everything from innocence to sexual desire, from triumph to defeat. The 20th-century art historian Kenneth Clark made a distinction between the “naked,” meaning unclothed and ashamed, and the “nude,” meaning the body in its most beautiful form. Most people today use the two words interchangeably, though.

The most influential male nude statues come from ancient Greece, starting in the sixth century B.C.E. There were a number of reasons for this cultural focus on the nude male body – in fact, the classics scholar Larissa Bonfante encouraged thinking of Greek nudity not just as a lack of clothing but as a “costume” in and of itself. In other words, nudity was something you wore in particular situations.

Artists portrayed many of the valued figures in Greek society – including gods, athletes, warriors and heroes – naked. Nudity was a feature of public life in certain settings: For example, athletes exercised and competed in the nude, and statues of the brawny nude demigod Herakles might adorn a temple. Nude, striding statues of young men called kouroi were used both as offerings to the gods and as grave markers.

Having a fine, athletic, youthful body, whether honed for athletic competition or for fighting wars, was not only a sign of being “kalos,” or beautiful, but also could prove your “arete,” or excellence.

Embodying ideals of beauty and excellence

These abstract ideals are exemplified in a famous statue called the “Spear Bearer,” made by the sculptor Polykleitos about 2,400 years ago. He believed that beauty was achieved through a harmony of parts. In addition to its symmetry, the “Spear Bearer” stands balanced in a “counterpoised” pose, with one supporting and one resting leg.

The “Spear Bearer” inspired many copies, including when it provided the model for the portrait of the first Roman emperor Augustus five centuries later.

The emperor is shown with the same athletic build and “counterpoised” stance, but he has been transformed into a specific portrait via his aristocratic toga clothing and elaborately detailed armor.

Here, the body of the emperor projects an overall message of confident heroism, while his garments fill in details about his status and achievements. This statue illustrates how clothing can be very specific to a moment, place or role, while classical nudity may look more timeless.

The classics reborn

Classical revivals such as the European Renaissance, around 1400-1600 C.E., and neoclassicism, around 1750-1900 C.E., brought back “heroic nudity,” each time helping it become even more a part of Western culture.

The rediscovery of ancient statues that had been buried in rubble after the fall of the Roman Empire excited artists of those eras, and they created many copies and adaptations of those models. Sketching and creating while studying nude live models became an important part of how artists trained, starting with the rise of art academies in the 1500s.

But like clothing, the nude “costume” could change over time.

For example, Michelangelo’s “David,” completed in 1504, imagines the Biblical hero as a pensive nude sporting only the rock and sling that will kill Goliath. The narrow-hipped body of “David” is a very different type from the “Spear Bearer” and does not fit Polykleitos’ ideal proportions.

Nudity continued to be associated with godlike beauty and power. Michelangelo’s “Risen Christ,” for instance, shows Jesus standing heroically nude, divine and resurrected.

And while an emperor would not usually have a nude portrait, French emperor Napoleon Bonaparte asked in 1802 to be sculpted as Mars, connecting him metaphorically to the Roman god of war and visually to the “Spear Bearer” and “Apollo Belvedere.”

A different standard for women

Female nudity in sculpture has its own history. Some of the earliest sculptures ever depict naked women with unnaturally exaggerated breasts, hips and pubic triangles, but scholars still disagree about how to interpret them.

For example, the 30,000-year-old Paleolithic “Woman from Willendorf,” discovered in 1908, was often called the “Venus of Willendorf,” associating her with the Roman goddess of love from tens of thousands of years later. But the figurine’s nakedness could have been more practical than erotic – to show bodily changes during pregnancy, for instance.

In ancient Mesopotamia 5,000 years ago, beautiful nudes depict both ideal women and goddesses. But in Greece, female nudity was considered inappropriate and did not become popular in statues until the fourth century B.C.E.

The best-known Greek female nude, the “Aphrodite of Knidos” by the sculptor Praxiteles, was revolutionary for its time and has inspired countless copies, particularly for her modest gesture covering her genitals. A Roman adaptation of this gesture covering both breasts and genitals is known as the Venus pudica type and is still seen frequently today.

In Egypt, the first female pharaoh Hatshepsut presents a fascinating case of artists figuring out how to treat a female body in a traditionally male role. Topless and wearing a kilt and false beard like other pharaohs, her body is sexually ambiguous – that of a ruler rather than a woman.

Artists work in tradition – or not

Artists of every culture have explored the human body as a subject, so artists today are following in a very, very long tradition when they sculpt or paint the human figure without clothes.

They can be aiming for something that doesn’t seem as tied to one specific time or place, the way using clothes from a particular moment would. Or they could be trying to express some of the same ideals the ancient sculptors were, such as perfection, immortality or divinity.

But many modern artists challenge these long traditions, creating statues of figures that are fully clothed. Consider Thomas J. Price’s “Grounded in the Stars”: a 12-foot, monumental sculpture of a woman standing in heroic counterpoise, wearing a T-shirt, leggings and comfortable shoes!

A well-designed 10-minute online exercise can spark small reductions in depression. That’s the key finding of my team’s paper, published in Nature Human Behaviour.

Many people believe that to start overcoming depression, they need a therapist, medication or a radical change in their environment. However, our study shows that taking small steps to learn practical skills can lead to measurable improvements in depressive symptoms.

In 2024, my team and I took to social media to pose a question to the field of mental health: If you could get 500 people struggling with depression to give you just 10 minutes of their attention, how would you spend that time? We received 66 responses from people around the world, including scientists, mental health app developers, popular YouTubers and students.

We chose what we considered the 12 most promising submissions to develop and rigorously test in one of the largest randomized controlled trials of mental health interventions ever conducted. These 12 “single-session interventions” ranged widely. Some used science-backed approaches emerging from in-person psychotherapy, while others were entirely novel. One featured a generative artificial intelligence-based expressive writing exercise. Another repurposed an inspirational Thai Life Insurance ad to show how helping others in small ways can make life more meaningful. Each intervention took under 10 minutes and was entirely self-guided.

In the study, we randomly assigned 7,505 American adult participants to complete one of the 12 single-session interventions or a control condition where they learned about trout. Participants answered questions about their well-being immediately after completing the intervention and again a month later. Each participant only completed the intervention (or control) one time.

Nearly all the interventions left users feeling hopeful and motivated to make positive changes immediately after completing them. But a month later, only two – Interactive Cognitive Reappraisal and Finding Focus – meaningfully reduced depression. These monthlong gains were small on average – around a 4% greater reduction on a standard depression measure for the top two exercises compared with the control – but small average effects can make a real difference, especially because these programs’ free, brief nature gives them a unique ability to reach people at a global scale.

Why it matters

Depression is a profound burden for the 332 million people it affects each year globally. While evidence-based treatments like psychotherapy are effective, long-term professional care is not an option for most people due to barriers like lack of access, cost and stigma. Our study is the first to show that single-session interventions can lead to monthlong reductions in depression in adults.

My team’s objective in studying single-session interventions is simple: If we can distill core elements of effective psychological treatments into short, user-friendly formats, many more people will be able to access science-backed support when they need it. The goal is not to replace therapists or psychiatrists, but to offer a reliable option for people who may otherwise receive no support at all. Single-session interventions like these can also be used to support traditional treatments, like for people on a waitlist to see a therapist.

What’s next

Having identified effective single-session interventions for overcoming depression, our top priority is to spread the word that these evidence-based brief mental health resources are available online at no cost. For example, Koko, the team that created the most impactful intervention in our study, created free five- to 10-minute interventions for a range of mental health challenges. You can also try all 12 of the single-session interventions we tested. Our published paper has more information about each one’s effectiveness.

My team is continuing to research single-session interventions and study their implementation in a range of settings, including social media, schools and therapy waitlists. Our collaborators are exploring how AI can make single-session interventions more engaging and personalized to users’ needs.

For many people, depression can make gaining control of one’s thoughts and feelings seem out of reach. This study shows that taking just 10 minutes to learn evidence-based skills can be a valuable first step toward longer-term improvement.

Since President Donald Trump issued a July 2025 executive order aimed at “ending crime and disorder on America’s streets,” national attention has increasingly focused on involuntary treatment as a response to visible homelessness and drug use.

A few months later, in September 2025, officials in Utah announced plans for a 16-acre facility on the edge of Salt Lake City that would hold up to 1,300 people experiencing homelessness after they are removed from public spaces and offered a choice: the facility’s abstinence-based shelter or jail time. The facility also plans to include 300 to 400 beds reserved for involuntary treatment, for adults who have psychiatric and substance use disorders.

Supporters of this facility describe it as a humane alternative to the streets, while detractors liken it to prison.

Since the release of the executive order, other proposals for expanding involuntary treatment for adults with substance use disorder have been cropping up across the U.S., including in New Jersey, Washington state and New York state.

I am a licensed clinical psychologist, substance-use treatment professional and researcher at the University of Washington. Throughout my three decades in the field, my research has focused on what works when it comes to substance use treatment, including among people experiencing homelessness.

I started reading research on involuntary treatment in 2018, when Ricky’s law – Washington’s version of involuntary treatment – was implemented where I live and work.

What I have learned is that involuntary treatment for adults with substance use disorders is necessary in extreme cases, but it does not outperform voluntary care and raises serious concerns about patient safety.

‘Involuntary’ or ‘forced’ treatment

People who have substance use disorder often experience pressure to enter treatment and stop using alcohol and drugs. This pressure ranges from informal coercion, like family pleas or providers leveraging housing or other services, to formal coercion, like treatment mandated by the court system.

Involuntary treatment, referred to in the U.S. as “involuntary civil commitment,” is distinct from these approaches and is the most restrictive means of formal coercion. Civil commitment authorizes a court, often based on a health care professional’s assessment, to order the involuntary deprivation of liberty, usually by confining a person to a locked treatment facility.

Unlike court-mandated treatment, which involves consent and choice, albeit limited, involuntary treatment does not involve consent and is often administered against a person’s will, with the length of treatment determined by court order and state law.

Such treatment is typically considered when a person poses an imminent risk of serious physical harm to themselves or others – for example, expressing suicidal or homicidal intent with a plan and means to carry it out. It may also be considered in cases of grave disability, such that an adult is unable to care for themselves without assistance.

A history of abuse

There is a reason involuntary treatment is reserved for these extreme cases. In the 19th and early 20th centuries, institutional abuses were rampant in state psychiatric hospitals, where patients were often confined and stripped of their civil rights for years, sometimes indefinitely. Through reforms in the 1960s, civil commitment law was applied in fewer cases, and legal protections for patients were strengthened.

But recent decades have seen a renewed interest in involuntary treatment specifically for substance use disorder. As of early 2026, 37 states and the District of Columbia have laws allowing involuntary treatment for substance use disorder, with most having added new and expanded civil commitment statutes in just the past 10 years.

In practice, these statutes vary widely in criteria, duration and utilization, reflecting a lack of consensus about their proper role.

Heightened risk of relapse, rearrest and death

Yet even as involuntary treatment for substance use disorder is being expanded, there is no clear scientific evidence that it is effective.

Three systematic reviews – wide-ranging analyses of the peer-reviewed, scientific literature – published in 2005, 2016 and 2023 have summarized the research on coercive substance use treatment in adults.

Within these reviews, some studies that are labeled as “involuntary treatment” actually refer to mandated but voluntary treatment, not civil commitment. When limited to studies of true involuntary treatment for substance use disorder, the literature indicates no measurable benefit and in some cases clear harm.

The most commonly cited harms are higher risk of relapse, rearrest and even death after release from treatment. In fact, one international research study showed that risk of death increases two- to nearly fourfold in the weeks following release, primarily due to overdose.

Unfortunately, there is no consistent and transparent program evaluation and reporting framework for involuntary substance use treatment in the U.S. To date, Massachusetts and Washington appear to be the only states to have published outcome evaluations of their involuntary substance use treatment programs.

Data from Massachusetts echoes the pattern reflected in the larger research literature: Adults with a history of involuntary treatment experienced 40% higher risk of death from overdose than people with no involuntary treatment history.

In its eight years of operation, Washington’s involuntary treatment program has published only one program evaluation. Findings showed mixed short-term results: There were modest reductions in emergency department use and homelessness, but lower rates of follow-up treatment for substance use and no change in arrests or employment. Most important, there has been no analysis of subsequent substance use outcomes or post-release mortality.

More data and more frequent reporting are needed to determine the effectiveness and safety of involuntary treatment for substance use disorder in the U.S.

In addition to documenting quantitative outcomes, documenting patients’ own subjective experiences of involuntary treatment for substance use disorder, as has been done for patients in involuntary treatment for psychiatric disorders, may help improve its delivery, even as it remains a last resort.

Calculating the cost

While patient health and civil liberties are top priorities, states also have to consider costs. It has been long documented that voluntary inpatient substance use treatment is substantially more expensive than lower-intensity, lower-barrier treatment and service settings. However, involuntary treatment layers on further costs of secured, statutorily designated placement with formal court proceedings and ongoing legal oversight.

Involuntary treatment under Massachusetts Section 35 law costs an estimated US$76,819 per male patient annually. In Washington, the average 11-day stay costs $7,298. Washington’s program yielded a low benefit-to-cost ratio, with the program losing approximately 81 cents for every dollar spent within the first year after treatment.

The few U.S. evaluations of involuntary treatment conducted to date have thus not indicated that involuntary treatment reduces publicly funded service costs sufficiently to offset its expense.

Other solutions

Meanwhile, the evidence consistently points to lower-barrier and voluntary approaches as more effective, less costly and less risky than involuntary treatment.

For people with substance use disorder who also experience homelessness, this includes a range of affordable and supportive housing options, from abstinence-based recovery housing to low-barrier permanent supportive housing paired with services, such as Housing First. Research shows Housing First effectively increases housing stability and reduces use of publicly funded services.

Evidence also supports implementing harm-reduction programs, including street-based engagement, syringe service programs and providing naloxone kits for overdose reversal. Collectively, these programs have been shown to prevent overdose, reduce transmission of blood-borne illness and connect people to voluntary services and treatment.

Effective behavioral treatments and medications that reduce craving and overdose risk, such as buprenorphine, methadone, naloxone and naltrexone, represent the gold standards in substance use treatment and overdose prevention.

Justice system diversion programs have been shown to be effective in keeping those convicted of low-level drug use and possession crimes out of jail. Case managers for these programs help participants find housing and vocational services, improving their stability. These programs reduce recidivism and relieve an already overloaded legal system.

Given the lack of existing evidence supporting involuntary treatment, I believe expanding it beyond acute, life-threatening crises is unwarranted. It is not a substitute for investing in and delivering lower-barrier, voluntary services that already have been shown to save lives, reduce harm and foster sustainable recovery.

Three rounds of nuclear talks between the U.S. and Iran failed to persuade President Donald Trump that a solution to the two country’s nuclear impasse lay in diplomacy, rather than military action. A perceived lack of progress in the last of those indirect negotiations on Feb 26, 2026, was enough to prompt Trump to green-light a massive onslaught of missiles that has degraded Iran’s offensive capabilities and killed Ayatollah Ali Khamenei and several members of Iran’s senior military leadership.

In response, Tehran has launched strikes across the Middle East, targeting Israel as well as Gulf states that host U.S. airbases. At least three Americans have been killed.

While the scale of the U.S., Israeli and Iranian strikes has taken some observers by surprise, the failure of the talks that led to them was all too predictable.

For diplomacy to be successful, both sides need to agree on the issues subject to negotiation and also believe that peaceful resolution is more valuable than military engagement. This clearly was not the case in the U.S.-Iran nuclear talks of 2025 and 2026.

As someone who has researched nonproliferation and U.S. national security for two decades and was involved in State Department nuclear diplomacy, I know that even under more favorable conditions, negotiations often fail. And the chances for success in the Iran-U.S. talks were always slim. In fact, publicly stated red lines by both sides were incompatible with each other – meaning negotiations were always likely to fail.

Iran wanted the talks confined only to guarantees about the civilian purpose of its nuclear program, not its missile program, support of regional proxy groups or human rights abuses. Essentially it wanted a return to 2015’s Joint Comprehensive Plan of Action, which halted Iran’s development of nuclear technology and stockpiling of nuclear material in exchange for lifting multiple international economic sanctions placed on Iran.

Meanwhile, Trump insisted on limits to Iran’s ballistic missiles and the cutting of Tehran’s support for regional militias. These were not included in the 2015 agreement, with parties ultimately deciding that a nuclear deal was better than the alternative of no deal at all.

False hope

Nevertheless, there had been a slim chance for a breakthrough of late.

While the positions of both the U.S. and Iranian governments had ossified since May 8, 2018 – the date when the first Trump administration withdrew the United States from the Obama-era Iran nuclear deal – there had been some recent movement by Iran, according to former U.S. diplomats involved in negotiations during the Obama and Biden administrations.

With U.S. military building up in the region, Iran appeared more willing to negotiate within the nuclear arena than before. There were plausible solutions to the issue of Iran’s enrichment of uranium capabilities, including maintaining a minimum domestic capacity to develop medical isotopes and a removal of Iran’s stockpile of enriched uranium necessary to build a nuclear bomb.

There was less openness on other points of contention. Notably, there was no movement on ballistic missiles, which had always been a red line. On the eve of the round of discussions held in Geneva on Feb. 17, Trump stated: “I think they want to make a deal.” Iran’s foreign minister, Abbas Araghchi, noted progress over the “guiding principles” of the talks.

But a lot of this optimism appeared to have dissipated by the time the two sides held another round of talks on Feb. 26. While mediator Oman’s negotiators continued to talk of progress, the U.S. side was noticeably silent. Reporting since has suggested that Trump was displeased with the way the talks had gone, setting the stage for the Feb. 28 attack.

Military brinkmanship

The threat of military action was, of course, a continued backdrop to the talks.

The USS Abraham Lincoln carrier group was deployed near Iranian waters in January as a signal of support to the Iranian protesters. The USS Gerald R Ford carrier group joined the buildup before the last round of talks.

Trump warned Iran that “if they don’t make a deal, the consequences are very steep.”

The thinking may have been that Iran, weakened by both the June 2025 U.S.-Israeli strikes and diminished capabilities of Tehran proxies Hamas and Hezbollah, was playing a weak hand in the talks.

Yet Iran also signaled a willingness to engage in military action. In the run-up to the last round of talks, Iran held military exercises and closed the Strait of Hormuz for a live-fire drill. Leaders in Tehran also declared that they would not restrain its response to another attack. The world is seeing that now, with a response that has seen Iran launch missiles across the Middle East and at rival Gulf nations.

Optimism has fallen before

Trump isn’t the first president to fail to secure a nuclear deal, although he is the first to respond to that failure with military action.

The Biden administration publicly pledged to strengthen and renew the Obama-era nuclear deal in 2021. However, Iran had significantly increased its nuclear technical capability during the years that had passed since the Joint Comprehensive Plan of Action collapsed. That increased the difficulty – just to return to the previous deal would have required Iran to give up the new technical capability it had achieved for no new benefits.

That window closed in 2022 after Iran removed all of the International Atomic Energy Agency’s surveillance and monitoring under the deal and started enriching uranium to near-weapons levels and stockpiling sufficient amounts for several nuclear weapons. The IAEA, the United Nations’ nuclear watchdog, maintains only normal safeguards that Iran had agreed to before the plan of action.

Optimism also existed for a short time in spring 2025 during five rounds of indirect talks that preceded the United States bombing Iran’s nuclear infrastructure in June as part of a broader Israeli attack.

A more unstable Middle East

When I worked in multilateral nuclear diplomacy for the U.S. State Department, we saw talks fail in 2009 regarding North Korea’s nuclear weapons program, after six years of on-and-off progress. The consequence of that failure is a more unstable East Asia and renewed interest by South Korea in developing nuclear weapons.

Unfortunately, the same dynamic appears to be playing out in the Middle East.

Military strikes have already killed more than 200 in Iran and across the region. A wider war in the Middle East is a possibility, and should the Iranian regime survive, it may commit to developing nuclear weapons given that the lack of them proved no deterrent to U.S. and Israeli military action.

Talks do not necessarily need an end point – in the shape of a deal – for them to have purpose. Under situations of increased military brinkmanship, talks could have helped the U.S. and Iran step back from the edge, build trust and perhaps develop better political relations – even if an actual deal remained out of reach.

Instead, Trump opted to go a different route.
