Eight years have elapsed since Pope Francis released โ€œLaudato Si,โ€ his encyclical urging โ€œcare for our common home.โ€ Though hailed as an eloquent plea to protect the environment, climate change was just one part of the popeโ€™s message, from encouraging solidarity with the poor to criticizing โ€œblind confidenceโ€ in technology.

On Oct. 4, 2023, Francis released an addendum to โ€œLaudato Si,โ€ addressed to โ€œall people of good will on the climate crisis.โ€ October 4 marks the feast day of the popeโ€™s namesake, St. Francis of Assisi, who famously loved all of creation. The new installment, โ€œLaudate Deumโ€ โ€“ โ€œPraise Godโ€ โ€“ is no less sweeping in the way it links environmental problems with economic, social and technological issues.

Like โ€œLaudato Si,โ€ the new document strongly reproaches wealthy nations that contribute the most to climate change, accusing them of ignoring the plight of the poor. It offers a similar rebuke of rampant individualism, lamenting that responses to global crises of climate change and the pandemic have led to โ€œgreater individualismโ€ and hoarding of wealth, rather than increased solidarity.

Scarcely any facet of modern life emerges unscathed by Francisโ€™ sometimes withering critiques. In his view, societies have failed to respond to crises that are profoundly interrelated: global inequality, pollution and even new forms of artificial intelligence that feed the illusion of humansโ€™ unlimited power. His 2015 broadside, in fact, targeted todayโ€™s โ€œtechnocratic paradigmโ€ with such vehemence that one critic likened these passages to the rantings of an โ€œAmish hippie.โ€

At the root of Earthโ€™s interlocking crises, the pope argued in 2015 and again in 2023, is a denial of the fact that all life exists in relationships. The larger whole in which all beings are embedded is, for Francis, both an inescapable reality and a source of wonder.

An integrated vision

I am an environmental ethicist, and my work explores both science and religion. And while these fields often look at the natural world through very different lenses, they also share a common value: wonder. Francisโ€™ social critique, I believe, stems from his vision of life โ€“ one filled with awe for the depth of meaning and mystery to be found in an interconnected world.

Conversely, the list of social and environmental ills Francis addresses in his environmental documents all involve a tendency to fracture and obscure the bigger picture โ€“ to ignore the larger context of each particular issue. He criticizes โ€œexcessive anthropocentrism,โ€ for example: overlooking humansโ€™ bonds with the rest of creation. Within society, excessive individualism similarly prioritizes โ€œpartsโ€ at the expense of the whole community.

Cheap consumer goods mask the full cost of production, such as the environmental and health costs of manufacturing, obscuring the relationship between customersโ€™ habits and their harmful consequences. The impacts of air travel, for example โ€“ air and noise pollution, land use, carbon emissions โ€“ are not factored into the ticket price. Failure to see these connections contributes to what Francis assails as an unsustainable โ€œthrowaway culture.โ€

Meanwhile, ubiquitous technology โ€“ with an app for everything at each personโ€™s fingertips โ€“ encourages a techno-fix mentality. Francisโ€™ environmental writings reprove tech solutions that target the symptoms of problems without addressing their deeper causes. Geoengineering may offer hope to mitigate the effects of climate change, but not if societies keep burning fossil fuels in the meantime. Social media supposedly helps build connections, but researchers have found that people who go on the apps to maintain relationships feel more lonely than other users. In an August 2023 speech, Francis warned of social mediaโ€™s โ€œreduction of human relationships to mere algorithms.โ€

Integral ecology

In Francisโ€™ eyes, all these problems result from denial of how deeply interconnected the world is. When humans attempt to declare โ€œindependence from reality,โ€ he writes, relationships are the first casualty.

The word โ€œrealityโ€ appears over 40 times in the popeโ€™s 2015 encyclical, by my count. In his 2023 addendum, Francis once more features the word prominently. He argues that nonhuman creatures have their own โ€œrealityโ€ and that climate change is a complex โ€œglobal realityโ€ that many try to deny, or simplify by blaming others โ€“ notably developing societies โ€“ rather than recognize their own role.

To understand what he means by โ€œreality,โ€ I look to the idea of โ€œintegral ecology,โ€ a term popularized by Francisโ€™ 2015 encyclical. In short, integral ecology is a holistic way of thinking about economic, social, political, ethical and environmental problems. The Earth is not confronting a variety of separate crises, Francis insists, but rather โ€œone complex crisisโ€ with many faces. His new document reinforces this idea, stressing that climate concerns are about more than ecology, because care for the Earth and care for one another are intimately linked.

Mystery in a dewdrop

The pope often turns to Saint Francis of Assisi, patron saint of animals, as a model of integral thought. The 13th century saint understood the โ€œinseparable bondโ€ that exists โ€œbetween concern for nature, justice for the poor, commitment to society, and interior peace,โ€ the pope wrote in 2015. St. Francis spoke of all of creation as family, praising โ€œMother Earth,โ€ โ€œBrother Moonโ€ and โ€œSister Sun.โ€

In 2015, the pope wrote admiringly about his namesakeโ€™s sense of awe, adding that without wonder, humansโ€™ attitude is that of โ€œmasters, consumers, ruthless exploiters.โ€

Indeed, wonder can create a shift in how people understand themselves in relation to something larger. There has recently been a renaissance of interest across many fields of study in the power of wonder to encourage behaviors that are good for the environment and for human health and relationships.

Psychologists have found that experiences of wonder can shrink the ego, encouraging generosity, humility and ethical decision-making. Wonder also weakens the perception of boundaries, increasing a personโ€™s sense of connection with something larger than the self. Other studies suggest that experiences of awe have the power to broaden peopleโ€™s moral concerns, increasing their consideration toward other humans, plants, animals and the environment.

For the pope, however, integral reality is about more than humans and nature; it encompasses relationships between all living things and God โ€“ an even larger, mysterious reality that is divine.

โ€œThe universe unfolds in God, who fills it completely,โ€ he writes in both documents. Therefore, โ€œThere is a mystical meaning to be found in a leaf, in a mountain trail, in a dewdrop, in a poor personโ€™s face.โ€ All are knit together in wondrous patterns of interconnection.
