Hannah Arendt has been on my thoughts quite a bit recently. The Twentieth-century German-Jewish political philosopher escaped the Nazi Holocaust, and gained regard as one of many world’s best public intellectuals at a time when few ladies had been appointed to school schools. She drew on historical past, literature and her personal life to determine the conditions beneath which open and liberal societies flip into authoritarian states. Seven many years in the past she made observations that also provide highly effective insights in the present day.
In The Origins of Totalitarianism,Arendtemphasized one main issue within the rise of authoritarianism that has little apparent connection to politics: loneliness. Whereas we normally assume of loneliness as not having our social wants met, Arendt outlined the phrase as one thing deeper. Loneliness occurs when there are not any shared goal information and no potential collective motion to unravel shared challenges. It’s a state of being the place you possibly can’t belief others. Loneliness, in Arendt’s telling, inflames the connective tissues of a society. It weakens the physique politic in order that demagogues and despots can prey. “What prepares males for totalitarian domination,” she wrote, “… is the truth that loneliness, as soon as a borderline expertise normally suffered in sure marginal social circumstances like outdated age, has turn into an on a regular basis expertise.”
Arendt—so far as I do know—didn’t use the phrase “irritation” to explain the results of social isolation on a rustic or tradition. Nevertheless it’s the metaphor that, to me, will get to the essence of her warning.

Inflammation is the body’s response to a way of risk—a protecting, contractionary response that may prolong even to the mobile degree. It’s a response that may inhibit therapeutic. A group or society that faces a deficit of significant connectedness is equally in a state of perpetual risk; individuals are unable to pay attention to 1 one other, to belief one another, to maintain trust in shared institutions, or to collectively overcome divisions.
This would possibly sound acquainted.
From 2003 to 2022, face-to-face socializing amongst U.S. men fell by 30 %. For teenagers, it was a staggering 45 percent. An estimated 12 % of People report having no close friends, a fourfold enhance since 1990. Whereas social media was purported to amplify human connection, the rise of comparison culture, social sorting into echo chambers and the fast decline of in-person social connection have as an alternative coincided with unprecedented levels of anxiety, depression and distrust.
It ought to subsequently come as no shock that, in America, we’re seeing democratic backsliding like Hannah Arendt warned of—together with mass polarization, intentional disinformation and a politics of concern, retribution and rage.
Loneliness inflames societies.
It simply so occurs that loneliness inflames the physique, too.
20 years in the past, researchers Louise Hawkley and John Cacioppo on the College of Chicago demonstrated in a landmark study that loneliness acts as a chronic stressor that triggers the physique’s innate stress-response programs. Social isolation retains the hypothalamic-pituitary-adrenal (HPA) axis in a continuing state of arousal, driving persistent cortisol launch. This hormonal imbalance heightens inflammation. And this could, in flip, weaken the immune system, compromise cardiovascular well being and worsen vulnerability to psychological well being circumstances resembling despair and anxiousness. In brief, the absence of significant social bonds can actually recalibrate the body’s physiological mechanisms towards higher stress and sickness.
Over the previous twenty years, additional research have solely bolstered the hyperlink between loneliness and inflammatory pathways. George Slavich of the College of California, Los Angeles, underscores that experiencing social disconnection can mimic bodily threats in how our brains and immune programs reply—magnifying the discharge of inflammatory brokers. From an evolutionary standpoint, sustained isolation disrupts our primal want for social integration—resulting in irritation and a complete host of downstream penalties.
It is simple to downplay the loneliness drawback. When former U.S. surgeon common Vivek Murthy warned of the risks of social isolation and proposed options, no significant authorities interventions ensued. Likewise, when the U.Ok. authorities appointed a minister for loneliness in 2018, many likened the transfer to a Monty Python sketch slightly than seeing it as a severe coverage intervention.
However the medical, social and even political prices of rising social isolation imply that we will now not afford to disregard it.
Some options are simple. Medical innovators at the moment are addressing social isolation via practices like “social prescribing”—whereby well being professionals connect patients who’re lonely with nonmedical group companies, volunteer packages, train teams and humanities actions to enhance their well-being. As an alternative of writing prescriptions for tablets, medical doctors can prescribe a free go to a museum, an invite to affix a gardening membership, or a assist group for folks dealing with comparable struggles. A current multiyear analysis of nature-oriented social prescribing within the U.Ok. discovered that packages considerably helped individuals cut back anxiousness and enhance happiness.
Different options are extra systemic. When Pete Buttigieg ran for president in 2020, he laid out an agenda for “belonging and healing”—emphasizing new funding and insurance policies round psychological well being and dependancy in addition to nationwide service to rebuild group establishments and promote environmental restoration. Leaders ought to suggest scaling up “belonging infrastructure”—transit, inexperienced areas, cultural venues, and psychological well being facilities—whereas increasing purpose-driven national service programs like Americorps and investing in native journalism via public grants or tax incentives to revive trusted data sources and restore necessary foundations of group life.
This ought to be a bipartisan trigger. Conservatives and liberals alike have a gap to deal with the disaster by leveraging religion and veterans’ teams–for instance, granting tax incentives or small federal matches that would assist church buildings, synagogues, and veterans’ teams construct mentoring initiatives, dependancy restoration assist and efforts to revitalize parks, libraries and civic areas. There’s additionally rising bipartisan recognition of the function of social media within the disaster. In tackling large tech’s influence on youth, leaders throughout the ideological spectrum ought to push towards full algorithmic transparency, restrictions to exploitative design options, and mandates for strong digital well-being protections for youngsters.
Like irritation within the physique, social isolation weakens our civic “immune system,” fueling polarization and making us extra vulnerable to authoritarian impulses. However Hannah Arendt emphasised that the situation is reversible. By investing within the foundations of shared belonging, we will restore our adapt to adapt to the challenges we face—from wildfires to pandemics to misinformation. It’s time to get severe about our therapeutic.
