Biocentrism (from Greek βίος bios, "life" and κέντρον kentron, "center"), in a political and ecological sense, as well as literally, is an ethical point of view that extends equal inherent value to all living things. It is an understanding of how the earth works, particularly as it relates to its biosphere or biodiversity. It stands in contrast to anthropocentrism, which centers on the value of humans, and to pathocentrism, which places value in sentient beings or beings capable of feeling pain. The related ecocentrism extends inherent value to the whole of nature.

Advocates of biocentrism often promote the preservation of biodiversity, animal rights, and environmental protection. The term has also been employed by advocates of "left biocentrism", which combines deep ecology with an "anti-industrial and anti-capitalist" position (according to David Orton et al.).

Definition In the simplest of terms as well as form, biocentrism is the belief that all living organisms, without exception, individually possess equal value and the same exact right to live, requiring identical moral treatment, regard, and prioritization.

Usually, the term biocentrism encompasses all environmental ethics that "extend the status of moral object from human beings to all living things in nature". Biocentric ethics calls for a rethinking of the relationship between humans and nature. It states that nature does not exist simply to be used or consumed by humans, but that humans are simply one species amongst many, and that because we are part of an ecosystem, any actions which negatively affect the living systems of which we are a part adversely affect us as well, whether or not we maintain a biocentric worldview. Biocentrists observe that all species have inherent value, and that humans are not "superior" to other species in a moral or ethical sense.

The four main pillars of a biocentric outlook are:

Humans and all other species are members of Earth's community. All species are part of a system of interdependence. All living organisms pursue their own "good" in their own ways. Human beings are not inherently superior to other living things.

The most important of these four main pillars is likely the idea that human beings are not inherently superior to other living things. People have divergent views on many specific aspects of almost everything. Not all biocentrists even subscribe to the abstract concept of value, which is why heavy emphasis is placed on the fourth pillar.

Relationship with animals and environment

Biocentrism views individual species as parts of the living biosphere. It observes the consequences of reducing biodiversity on both small and large scales and points to the inherent value all species have to the environment.

The environment is seen for what it is; the biosphere within which we live and depend on the maintaining of its diversity for our health. From these observations the ethical points are raised.

History and development

Biocentric ethics differs from classical and traditional ethical thinking. Rather than focusing on strict moral rules, as in Classical ethics, it focuses on attitudes and character. In contrast with traditional ethics, it is nonhierarchical and gives priority to the natural world rather than to humankind exclusively.

Biocentric ethics includes Albert Schweitzer's ethics of "Reverence for Life", Peter Singer's ethics of Animal Liberation and Paul W. Taylor's ethics of biocentric egalitarianism.

Albert Schweitzer's "reverence for life" principle was a precursor of modern biocentric ethics. In contrast with traditional ethics, the ethics of "reverence for life" denies any distinction between "high and low" or "valuable and less valuable" life forms, dismissing such categorization as arbitrary and subjective. Conventional ethics concerned itself exclusively with human beings—that is to say, morality applied only to interpersonal relationships—whereas Schweitzer's ethical philosophy introduced a "depth, energy, and function that differ[s] from the ethics that merely involved humans". "Reverence for life" was a "new ethics, because it is not only an extension of ethics, but also a transformation of the nature of ethics".

Similarly, Peter Singer argues that non-human animals deserve the same equality of consideration that we extend to human beings. His argument is roughly as follows:

Membership in the species Homo sapiens is the only criterion of moral importance that includes all humans and excludes all non-humans. Using membership in the species Homo sapiens as a criterion of moral importance is completely arbitrary. Of the remaining criteria we might consider, only sentience is a plausible criterion of moral importance. Using sentience as a criterion of moral importance entails that we extend the same basic moral consideration (i.e. "basic principle of equality") to other sentient creatures that we do to human beings. Therefore, we ought to extend to animals the same equality of consideration that we extend to human beings.

Singer's work, while notable in the canon of environmental ethics, should not be considered as fully biocentric. Singer's ethics is extended from humans to nonhuman animals because the criterion for moral inclusion (sentience) is found in both humans and nonhuman animals, thus it would be arbitrary to deny it to nonhuman animals simply because they were not human. However, not all biological entities are sentient, consider: algae, plants and trees, fungi, lichens, mollusks, protozoa, for example. For an ethical theory to be biocentric, it must have a reason for extending ethical inclusion to the entire biosphere (as in Taylor and Schweitzer). The requirement for environmental ethics to move beyond sentience as criteria for inclusion in the moral realm is discussed in Tom Regan's 1981 paper "The Nature and Possibility of an Environmental Ethic".

Biocentrism is most commonly associated with the work of Paul W. Taylor, especially his book Respect for Nature: A Theory of Environmental Ethics (1986). Taylor maintains that biocentrism is an "attitude of respect for nature", whereby one attempts to make an effort to live one's life in a way that respects the welfare and inherent worth of all living creatures. Taylor states that:

Humans are members of a community of life along with all other species, and on equal terms. This community consists of a system of interdependence between all members, both physically, and in terms of relationships with other species. Every organism is a "teleological centre of life", that is, each organism has a purpose and a reason for being, which is inherently "good" or "valuable". Humans are not inherently superior to other species.

Historian Donald Worster traces today's biocentric philosophies, which he sees as part of a recovery of a sense of kinship between man and nature, to the reaction by the British intelligencia of the Victorian era against the Christian ethic of dominion over nature. He has pointed to Charles Darwin as an important spokesman for the biocentric view in ecological thought and quotes from Darwin's Notebook on Transmutation of Species (1837): If we choose to let conjecture run wild, then animals, our fellow brethren in pain, diseases, death, suffering and famine—our slaves in the most laborious works, our companions in our amusement—they may partake of our origin in one common ancestor—we may be all netted together.

In 1859, Charles Darwin published his book On the Origin of Species. This publication sparked the beginning of biocentrist views by introducing evolution and "its removal of humans from their supernatural origins and placement into the framework of natural laws".

The work of Aldo Leopold has also been associated with biocentrism. The essay "The Land Ethic" in Leopold's book Sand County Almanac (1949) points out that although throughout history women and slaves have been considered property, all people have now been granted rights and freedoms. Leopold notes that today land is still considered property as people once were. He asserts that ethics should be extended to the land as "an evolutionary possibility and an ecological necessity". He argues that while people's instincts encourage them to compete with others, their ethics encourage them to co-operate with others. He suggests that "the land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land". In a sense this attitude would encourage humans to co-operate with the land rather than compete with it.

Outside of formal philosophical works biocentric thought is common among pre-colonial tribal peoples who knew no world other than the natural world.

In law The paradigm of biocentrism and the values that it promotes are beginning to be used in law.

In recent years (as of 2011), cities in Maine, Pennsylvania, New Hampshire and Virginia have adopted laws that protect the rights of nature. The purpose of these laws is to prevent the degradation of nature, especially by corporations who may want to exploit natural resources and land space, and to also use the environment as a dumping ground for toxic waste.

The first country to include rights of nature in its constitution is Ecuador (see 2008 Constitution of Ecuador). Article 71 states that nature "has the right to integral respect for its existence and for the maintenance and regeneration of its life cycles, structure, functions and evolutionary processes".

In religion

Islam

In Islam, biocentric ethics stem from the belief that all of creation belongs to Allah (God), not humans, and to assume that non-human animals and plants exist merely to benefit humankind leads to environmental destruction and misuse. As all living organisms exist to praise God, human destruction of other living things prevents the earth's natural and subtle means of praising God. The Qur'an acknowledges that humans are not the only all-important creatures and emphasizes a respect for nature. Muhammad was once asked whether there would be a reward for those who show charity to nature and animals, to which he replied, "for charity shown to each creature with a wet heart [i.e. that is alive], there is a reward."

Hinduism Hinduism contains many elements of biocentrism. In Hinduism, humans have no special authority over other creatures, and all living things have souls ('atman'). Brahman (God) is the "efficient cause" and Prakrti (nature), is the "material cause" of the universe. However, Brahman and Prakrti are not considered truly divided: "They are one in [sic] the same, or perhaps better stated, they are the one in the many and the many in the one."

However, while Hinduism does not give the same direct authority over nature that the Judeo-Christian-Islamic god grants, they are subject to a "higher and more authoritative responsibility for creation". The most important aspect of this is the doctrine of Ahimsa (non-violence). The Yājñavalkya Smṛti warns, "the wicked person who kills animals which are protected has to live in hell fire for the days equal to the number of hairs on the body of that animal". The essential aspect of this doctrine is the belief that the Supreme Being incarnates into the forms of various species. The Hindu belief in Saṃsāra (the cycle of life, death and rebirth) encompasses reincarnation into non-human forms. It is believed that one lives 8,400,000 lifetimes before one becomes a human. Each species is in this process of samsara until one attains moksha (liberation).
