Speciesism is a term used in philosophy regarding the treatment of individuals of different species. The term has several different definitions. Some specifically define speciesism as discrimination or unjustified treatment based on an individual's species membership, while others define it as differential treatment without regard to whether the treatment is justified or not. Richard D. Ryder, who coined the term, defined it as "a prejudice or attitude of bias in favour of the interests of members of one's own species and against those of members of other species". Speciesism results in the belief that humans have the right to use non-human animals in exploitative ways which is pervasive in the modern society. Studies from 2015 and 2019 suggest that people who support animal exploitation also tend to have intersectional bias that encapsulates and endorses racist, sexist, and other prejudicial views, which furthers the beliefs in human supremacy and group dominance to justify systems of inequality and oppression.
Animal Liberation: A New Ethics for Our Treatment of Animals is a 1975 book by Australian philosopher Peter Singer. It is widely considered within the animal liberation movement to be the founding philosophical statement of its ideas. Singer himself rejected the use of the theoretical framework of rights when it comes to human and nonhuman animals. Following Jeremy Bentham, Singer argued that the interests of animals should be considered because of their ability to experience suffering and that the idea of rights was not necessary in order to consider them. He popularized the term "speciesism" in the book, which had been coined by Richard D. Ryder to describe the exploitative treatment of animals.
Tom Regan was an American philosopher who specialized in animal rights theory. He was professor emeritus of philosophy at North Carolina State University, where he had taught from 1967 until his retirement in 2001.
The animal rightsmovement, sometimes called the animal liberation, animal personhood, or animal advocacy movement, is a social movement that advocates an end to the rigid moral and legal distinction drawn between human and non-human animals, an end to the status of animals as property, and an end to their use in the research, food, clothing, and entertainment industries.
Kantian ethics refers to a deontological ethical theory developed by German philosopher Immanuel Kant that is based on the notion that "I ought never to act except in such a way that I could also will that my maxim should become a universal law." It is also associated with the idea that "it is impossible to think of anything at all in the world, or indeed even beyond it, that could be considered good without limitation except a good will." The theory was developed in the context of Enlightenment rationalism. It states that an action can only be moral if it is motivated by a sense of duty, and its maxim may be rationally willed a universal, objective law.
Animal rights is the philosophy according to which many or all sentient animals have moral worth independent of their utility to humans, and that their most basic interests—such as avoiding suffering—should be afforded the same consideration as similar interests of human beings. Broadly speaking, and particularly in popular discourse, the term "animal rights" is often used synonymously with "animal protection" or "animal liberation". More narrowly, "animal rights" refers to the idea that many animals have fundamental rights to be treated with respect as individuals—rights to life, liberty, and freedom from torture that may not be overridden by considerations of aggregate welfare.
The argument from marginal cases is a philosophical argument within animal rights theory regarding the moral status of non-human animals. Its proponents hold that if human infants, senile people, the comatose, and cognitively disabled people have direct moral status, non-human animals must have a similar status, since there is no known morally relevant characteristic that those marginal-case humans have that animals lack. "Moral status" may refer to a right not to be killed or made to suffer, or to a general moral requirement to be treated in a certain way.

Paul W. Taylor was an American philosopher best known for his work in the field of environmental ethics.
Animal ethics is a branch of ethics which examines human-animal relationships, the moral consideration of animals and how nonhuman animals ought to be treated. The subject matter includes animal rights, animal welfare, animal law, speciesism, animal cognition, wildlife conservation, wild animal suffering, the moral status of nonhuman animals, the concept of nonhuman personhood, human exceptionalism, the history of animal use, and theories of justice. Several different theoretical approaches have been proposed to examine this field, in accordance with the different theories currently defended in moral and political philosophy. There is no theory which is completely accepted due to the differing understandings of what is meant by the term ethics; however, there are theories that are more widely accepted by society such as animal rights and utilitarianism.
Abolitionism or abolitionist veganism is the animal rights based opposition to all animal use by humans. Abolitionism intends to eliminate all forms of animal use by maintaining that all sentient beings, humans or nonhumans, share a basic right not to be treated as properties or objects. Abolitionists emphasize that the production of animal products requires treating animals as property or resources, and that animal products are not necessary for human health in modern societies. Abolitionists believe that everyone who can live vegan is therefore morally obligated to be vegan.
The concept of moral rights for animals is believed to date as far back as Ancient India, particularly early Jainist and Hindu history. What follows is mainly the history of animal rights in the Western world. There is a rich history of animal protection in the ancient texts, lives, and stories of Eastern, African, and Indigenous peoples.
Joan Dunayer is an American philosopher and abolitionist animal rights advocate. She is the author of two books, Animal Equality (2001) and Speciesism (2004). She has argued for "species equality" the view that all animals including insects should be given rights.
Raymond G. Frey was a professor of philosophy at Bowling Green State University, specializing in moral, political and legal philosophy, and author or editor of a number of books. He was a noted critic of animal rights.
Alasdair Cochrane is a British political theorist and ethicist who is currently Professor of Political Theory in the Department of Politics and International Relations at the University of Sheffield. He is known for his work on animal rights from the perspective of political theory, which is the subject of his two books: An Introduction to Animals and Political Theory and Animal Rights Without Liberation. His third book, Sentientist Politics, was published by Oxford University Press in 2018. He is a founding member of the Centre for Animals and Social Justice, a UK-based think tank focused on furthering the social and political status of nonhuman animals. He joined the Department at Sheffield in 2012, having previously been a faculty member at the Centre for the Study of Human Rights, London School of Economics. Cochrane is a Sentientist. Sentientism is a naturalistic worldview that grants moral consideration to all sentient beings.
Animal Rights Without Liberation: Applied Ethics and Human Obligations is a 2012 book by the British political theorist Alasdair Cochrane, in which it is argued that animal rights philosophy can be decoupled from animal liberation philosophy by the adoption of the interest-based rights approach. Cochrane, arguing that there is no reason that (nonhuman) animals should be excluded from justice, adopts Joseph Raz's account of interest rights and extends it to include animals. He argues that sentient animals possess a right not to be made to suffer and a right not to be killed, but not a right to freedom. The book's chapters apply Cochrane's account to a number of interactions between humans and animals; first animal experimentation, then animal agriculture, the genetic engineering of animals, the use of animals in entertainment and sport, the relationship of animals to environmental practices and the use of animals in cultural practices.
Evelyn B. Pluhar-Adams is an American philosopher specialising in moral philosophy and the philosophy of mind, especially concerning the moral status of animals.
The relationship between animal ethics and environmental ethics concerns the differing ethical consideration of individual nonhuman animals—particularly those living in spaces outside of direct human control—and conceptual entities such as species, populations and ecosystems. The intersection of these two fields is a prominent component of vegan discourse.
Insects and human ethical obligations towards them have been discussed by a number of writers and figures throughout history, many of whom, arguing from a variety of different perspectives, have contended that there exists a moral obligation towards not harming or killing insects. According to generally accepted definitions in animal welfare and agricultural ethics, however, it is argued that individual insects do not have a "right to life".
Wild Animal Ethics: The Moral and Political Problem of Wild Animal Suffering is a 2020 book by the philosopher Kyle Johannsen, that examines whether humans, from a deontological perspective, have a duty to reduce wild animal suffering. He concludes that such a duty exists and recommends effective interventions that could be potentially undertaken to help these sentient individuals.
