Sentience in the context of "Sanctity of life"

Animal welfare is the quality of life and overall well-being of animals. Formal standards of animal welfare vary between contexts, but are debated mostly by animal welfare groups, legislators, and academics. Animal welfare science uses measures such as longevity, disease, immunosuppression, behavior, physiology, and reproduction, although there is debate about which of these best indicate animal welfare.

Respect for animal welfare is often based on the belief that nonhuman animals are sentient and that consideration should be given to their well-being or suffering, especially when they are under the care of humans. These concerns can include how animals are slaughtered for food, how they are used in scientific research, how they are kept (as pets, in zoos, farms, circuses, etc.), and how human activities affect the welfare and survival of wild species.

Emanationism is a speculative theory in the cosmology or cosmogony of certain religious and philosophical systems, that posits the concept of emanation. According to this theory, emanation, from the Latin emanare meaning "to flow from" or "to pour forth or out of", is the mode by which all existing things are derived from a 'first reality', or first principle. In the emanationist concept all things are derived from this first reality or perfect God, by consecutive steps of degradation, to a lower degree of this first reality or God: at every consecutive step the emanating beings are less pure, less perfect, less divine. Emanationism posits a transcendent principle from which everything is derived, as opposed to creationism, that considers the universe to be created by a sentient God who is separate from creation, and to materialism, which posits no underlying subjective and/or ontological nature behind phenomena, all phenomena being considered immanent.

In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that lead to the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea that underpins them all is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as the capacity of actions or objects to produce benefits, such as pleasure, happiness, and good, or to prevent harm, such as pain and unhappiness, to those affected.

Utilitarianism is a version of consequentialism, which states that the consequences of any action are the only standard of right and wrong. Unlike other forms of consequentialism, such as egoism and altruism, egalitarian utilitarianism considers either the interests of all humanity or all sentient beings equally. Proponents of utilitarianism have disagreed on a number of issues, such as whether actions should be chosen based on their likely results (act utilitarianism), or whether agents should conform to rules that maximize utility (rule utilitarianism). There is also disagreement as to whether total utility (total utilitarianism) or average utility (average utilitarianism) should be maximized.

Jīva (Sanskrit: जीव) is a philosophical term used within Jainism to identify the soul. As per Jain cosmology, jīva is the principle of sentience and is one of the tattvas or one of the fundamental substances forming part of the universe. The jiva, according to Jainism, is an essential part of how the process of karma, rebirth and the process of liberation from rebirth works.

Mahayana is the largest branch of Buddhism, followed by Theravada. It is a broad group of Buddhist traditions, texts, philosophies, and practices developed in ancient India (c. 1st century BCE onwards). Mahāyāna accepts the main scriptures and teachings of early Buddhism but also recognizes various doctrines and texts that are not accepted by Theravada Buddhism as original. These include the Mahāyāna sūtras and their emphasis on the bodhisattva path and Prajñāpāramitā. Vajrayana or Mantra traditions are a subset of Mahāyāna which makes use of numerous Tantric methods Vajrayānists consider to help achieve Buddhahood.

Mahāyāna also refers to the path of the bodhisattva striving to become a fully awakened Buddha for the benefit of all sentient beings, and is thus also called the "Bodhisattva Vehicle" (Bodhisattvayāna). Mahāyāna Buddhism generally sees the goal of becoming a Buddha through the bodhisattva path as being available to all and sees the state of the arhat as incomplete. Mahāyāna also includes numerous Buddhas and bodhisattvas that are not found in Theravada (such as Amitābha and Vairocana). Mahāyāna Buddhist philosophy also promotes unique theories, such as the Madhyamaka theory of emptiness (śūnyatā), the Vijñānavāda ("the doctrine of consciousness" also called "mind-only"), and the Buddha-nature teaching.

Survival or survivorship, the act of surviving, is the propensity of something to continue existing, particularly when this is done despite conditions that might kill or destroy it. The concept can be applied to humans and other living things (or, hypothetically, any sentient being), to a physical object, and to abstract things such as beliefs or ideas. Living things generally have a self-preservation instinct to survive, while objects intended for use in harsh conditions are designed for survivability.

In Buddhism, sentient beings or living beings are beings with consciousness, sentience, or in some contexts life itself.

Vegetarianism is the practice of abstaining from the consumption of meat (red meat, poultry, seafood, insects, and the flesh of any other animal). It may also include abstaining from eating all by-products of animal slaughter. A person who practices vegetarianism is known as a vegetarian.

Vegetarianism may be adopted for various reasons. Many people object to eating meat out of respect for sentient animal life. Such ethical motivations have been codified under various religious beliefs as well as animal rights advocacy. Other motivations for vegetarianism are health-related, political, environmental, cultural, aesthetic, economic, taste-related, or relate to other personal preferences. Vegans are regularly also described as vegetarians, especially by carnists.
