A person (pl.: people or persons, depending on context) is a being who has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility.[1][2][3][4] The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts.[5][6]
In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes.
The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of person. The plural form "persons" is often used in philosophical and legal writing.
The criteria for being a person... are designed to capture those attributes which are the subject of our most humane concern with ourselves and the source of what we regard as most important and most problematical in our lives.
Personhood is the status of being a person. Defining personhood is a controversial topic in philosophy and law, and is closely tied to legal and political concepts of citizenship, equality, and liberty. According to common worldwide general legal practice, only a natural person or legal personality has rights, protections, privileges, responsibilities, and legal liability. Personhood continues to be a topic of international debate, and has been questioned during the abolition of slavery and the fight for women's rights, in debates about abortion, fetal rights, and in animal rights advocacy.[7][6]
Various debates have focused on questions about the personhood of different classes of entities. Historically, the personhood of women, and slaves has been a catalyst of social upheaval. In most societies today, postnatal humans are defined as persons. Likewise, certain legal entities such as corporations, sovereign states and other polities, or estates in probate are legally defined as persons.[8] However, some people believe that other groups should be included; depending on the theory, the category of "person" may be taken to include or not pre-natal humans or such non-human entities as animals, artificial intelligences, or extraterrestrial life.
