The Last Island is a book written by Adam Goodheart, who is a contemporary hystorian, essayist and author.
The Field of Anthropology
According to the U.S. Bureau of Labor Statistics, anthropologists and archaeologists held approximately 8,800 jobs in 2024, and employment in the field is projected to grow by 4% between 2024 and 2034. The median annual salary was reported to be $64,910, and most positions require at least a master’s degree. To enter the occupation, anthropologists and archaeologists typically
need at least a master’s degree in anthropology or archaeology. Employers may prefer to hire candidates who have experience doing fieldwork in their discipline.
Cultural anthropologists often work in universities, research institutes, museums, governmental agencies, and organizations dealing with indigenous rights and cultural heritage. My particular interest here lies in the anthropology of isolated
indigenous communities, such as the Sentinelese of North Sentinel Island, and the ethical debates concerning the protection of uncontacted peoples.
A relevant institution in the field of anthropology and indigenous studies is UNESCO. The organisation plays an important role in promoting the rights of Indigenous Peoples, as well as in safeguarding their cultural and linguistic diversity. According to UNESCO, it supports Indigenous communities through programmes such as the Local and Indigenous Knowledge Systems (LINKS) initiative, which aims to integrate indigenous knowledge into global decisionmaking processes and sustainable development policies.
In addition, UNESCO works on protecting intangible cultural heritage and encouraging the participation of Indigenous Peoples in the management of World Heritage sites, recognising them as key stewards of global biodiversity and cultural diversity.
In practice, anthropologists working in or with UNESCO-related frameworks may contribute to research on traditional knowledge systems, assist in documenting endangered languages, or collaborate with local communities in order to ensure that cultural heritage is preserved in a way that respects indigenous agency. This reflects a broader shift in anthropology from extractive
fieldwork models toward participatory and rights-based approaches, where communities are not only objects of study but active partners in knowledge production.
A historical and anthropological account of North Sentinel Island and the Sentinelese people
The book raised for me a number of ethical questions concerning cultural preservation, isolation, and the legitimacy
of outside intervention, which leads me to explore anthropology as a possible academic and professional field in the future.
In his book, Goodheart mentions the famous account of a young American missionary, John Allen Chau who, in 2018
adventured to North Sentinel Island with the goal to spread the Gospel to the most uncontacted tribe in the world. Whether what he did was noble or stupid is left to the rest of us.
As a matter of fact, there is also a 2023 documentary talking about this very thing, called The mission. Goodheart asks in his book: “I have sometimes wondered whether Chau’s secular critics are just as delusional, just as much in thrall to their own mythology. Visions of the Sentinelese dwelling in happy perpetuity on their island are probably almost as unrealistic as visions of them dancing eternally with John Chau around the throne of Jesus” (p 218).
Now, both the book and the documentary push us to ask a few relevant questions:
What are the limits of anthropological research? Do uncontacted communities have a moral right to remain uncontacted? Is scientific curiosity sufficient to justify contact? How can the desire for knowledge be reconciled with respect for the autonomy of other cultures?
Every time Adam Goodheart mentions an episode where an ineny (“both they and the Jarawa refer to outsiders as ineny, a term deriving from ineny-lau, the spirits who come from the sea” (p 63)) takes hold of the indigenous and bring them to the so-called “civilized” world, they always end up either getting sick or dying of disease. In one of his journeys, when Goodheart asks a native from Jarawa who learned some basic English language what he dislikes about the civilized world, he replied that it was full of diseases.
That makes me think that the law given by India to protect the Island has at its basis an ethical dimension. Its peoples must
be protected first of all because they lack our immunity. Just by contact they can easily disappear, although usually when they come across to our part of the world. However, authorities in India did fear that John Chau’s interference with the Sentinelese could spread some disease amongst them.
The Missconception of “Discovery”
In terms of relevant developments in the field, the book allows for a discussion of a significant shift in contemporary anthropology: the move away from earlier models based on “discovery” and direct contact with isolated populations, toward
a stronger emphasis on indigenous rights, self-determination, and policies of nonintervention. The case of the Sentinelese is often cited as an example of this broader paradigm shift, in which the ethical risks of contact are increasingly seen as outweighing the epistemic gains of direct access. Adam Goodheart writes:
“Another common theme is that today’s “lost” tribes are usually not so much lost
as they are in hiding: a matter of prudent foreign policy. Indeed, many of today’s
experts avoid the term “uncontacted” – which implies that those groups are still
ripe for discovery – preferring ‘indigenous peoples in voluntary isolation’ “ (p
24).
Of course, this withdrawal has to do with past encounters with the outside world that have gone unrecorded and also warnings past by other tribes through word of mouth. This change in terminology reflects a deeper epistemological shift in anthropology, where the emphasis is no longer placed on gaining direct access to “unknown” cultures, but rather on acknowledging the agency of groups who actively maintain distance from the outside world.
At the same time, this development raises methodological challenges, as it limits the possibility of traditional fieldwork and forces anthropologists to rely more heavily on indirect
forms of evidence. The Sentinelese case represents an extreme example of this tension, where ethical considerations and state policy effectively replace the possibility of anthropological observation with protection and non-interference.
Ethics of Protection
Within this broader shift, the case of North Sentinel Island functions as a paradigmatic ethical case study. The Sentinelese people are among the most isolated populations in the world, and their protection is enforced by strict Indian government policies that prohibit contact and restrict access to the island. This makes North Sentinel not only an anthropological subject, but also a legal andmoral boundary-zone, where questions of knowledge, sovereignty, and harm intersect.
The central ethical tension in this case lies in the question of intervention: whether any external attempt to establish contact can ever be justified, even in the name of scientific knowledge, humanitarian concern, or religious belief. On the one hand, non-intervention can be seen as a form of respect for autonomy and cultural self-determination, acknowledging the possibility that isolation itself may be a conscious or culturally embedded form of protection.
On the other hand, the absolute refusal of contact raises questions about epistemic limits and moral responsibility, particularly in situations where ignorance about the group’s internal conditions leaves open hypothetical concerns about vulnerability or lack of medical immunity. This tension directly informs my guiding question: to what extent can or should external agents intervene in the lives of isolated communities, and how can anthropology reconcile its commitment to knowledge production with an increasing ethical emphasis on non-interference? In this sense, North Sentinel is not simply an object of study, but a limit-case that exposes the boundaries of both anthropological inquiry and moral justification within the field.
