Speciesism is a term used in philosophy regarding the treatment of individuals of different species. The term has several different definitions within the relevant literature. Some sources specifically define speciesism as discrimination or unjustified treatment based on an individual's species membership, while other sources define it as differential treatment without regard to whether the treatment is justified or not. Richard 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, which scholars say is pervasive in the modern society. Studies from 2015 and 2019 suggest that people who support animal exploitation also tend to endorse racist, sexist, and other prejudicial views, which furthers the beliefs in human supremacy and group dominance to justify systems of inequality and oppression.
Anthropocentrism is the belief that human beings are the central or most important entity on the planet. The term can be used interchangeably with humanocentrism, and some refer to the concept as human supremacy or human exceptionalism. From an anthropocentric perspective, humankind is seen as separate from nature and superior to it, and other entities are viewed as resources for humans to use.
Henry Shakespear Stephens Salt was an English writer and campaigner for social reform in the fields of prisons, schools, economic institutions, and the treatment of animals. He was a noted ethical vegetarian, anti-vivisectionist, socialist, and pacifist, and was well known as a literary critic, biographer, classical scholar and naturalist. It was Salt who first introduced Mohandas Gandhi to the influential works of Henry David Thoreau, and influenced Gandhi's study of vegetarianism. Salt is considered, by some, to be the "father of animal rights," having been one of the first writers to argue explicitly in favour of animal rights, rather than just improvements to animal welfare, in his Animals' Rights: Considered in Relation to Social Progress (1892).

The predation problem or predation argument refers to the consideration of the harms experienced by animals due to predation as a moral problem, that humans may or may not have an obligation to work towards preventing. Discourse on this topic has, by and large, been held within the disciplines of animal and environmental ethics. The issue has particularly been discussed in relation to animal rights and wild animal suffering. Some critics have considered an obligation to prevent predation as untenable or absurd and have used the position as a reductio ad absurdum to reject the concept of animal rights altogether. Others have criticized any obligation implied by the animal rights position as environmentally harmful.

It expands on the ideas espoused in his 1906 book, The Universal Kinship.
Moral circle expansion is an increase over time in the number and type of entities given moral consideration. The general idea of moral inclusion was discussed by ancient philosophers and since the 19th century has inspired social movements related to human rights and animal rights. Especially in relation to animal rights, the philosopher Peter Singer has written about the subject since the 1970s, and since 2017 so has the think tank Sentience Institute, part of the 21st-century effective altruism movement. There is significant debate on whether humanity actually has an expanding moral circle, considering topics such as the lack of a uniform border of growing moral consideration and the disconnect between people's moral attitudes and their behavior. Research into the phenomenon is ongoing.
