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

'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 Ludwig Philipp Albert Schweitzer (; 14 January 1875 – 4 September 1965) was a German and French polymath from Alsace. He was a theologian, organist, musicologist, writer, humanitarian, philosopher, and physician. As a Lutheran minister, ...
'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 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 Sentience is the ability to experience feelings and sensations. It may not necessarily imply higher cognitive functions such as awareness, reasoning, or complex thought processes. Some writers define sentience exclusively as the capacity for ''v ...
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 "

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

Another essential Jain teaching is self-restraint. Jainism discourages wasting the gifts of nature, and encourages its practitioners to reduce their needs as far as possible.

's teachings encourage people "to live simply, to cherish tranquility, to appreciate the natural cycle of life". Buddhism emphasizes that everything in the universe affects everything else. "Nature is an ecosystem in which trees affect climate, the soil, and the animals, just as the climate affects the trees, the soil, the animals and so on. The ocean, the sky, the air are all interrelated, and interdependent—water is life and air is life." Although this holistic approach is more ecocentric than biocentric, it is also biocentric, as it maintains that all living things are important and that humans are not above other creatures or nature. Buddhism teaches that "once we treat nature as our friend, to cherish it, then we can see the need to change from the attitude of dominating nature to an attitude of working with nature—we are an intrinsic part of all existence rather than seeing ourselves as in control of it."

Criticism

Biocentrism has faced criticism for a number of reasons. Some of this criticism grows out of the concern that biocentrism is an anti-human paradigm and that it will not hesitate to sacrifice human well-being for the greater good. Biocentrism has also been criticized for its

, which sees humans as having a higher status than other species, biocentrism puts humans on a par with the rest of nature, and not above it. In his essay ''A Critique of Anti-Anthropocentric Biocentrism'' Richard Watson suggests that if this is the case, then "Human ways—human culture—and human actions are as natural as the ways in which any other species of animals behaves". He goes on to suggest that if humans must change their behavior to refrain from disturbing and damaging the natural environment, then that results in setting humans apart from other species and assigning more power to them. This then takes us back to the basic beliefs of anthropocentrism. Watson also claims that the extinction of species is "Nature's way" and that if humans were to instigate their own self-destruction by exploiting the rest of nature, then so be it. Therefore, he suggests that the real reason humans should reduce their destructive behavior in relation to other species is not because we are equals but because the destruction of other species will also result in our own destruction. This view also brings us back to an anthropocentric perspective.
