What is a person?
Why does it matter?
“Human” rights: do you have to be human to
deserve human rights?
Restricted rights? Rights of protection, etc.
granted to children, the severely mentally ill and
others that are not granted full human rights
The right to be counted in utilitarian calculations,
i.e. to have one’s pleasure and suffering matter
morally
What does it take to be a person?
1) A member of the species Homo sapiens
• People vs. “persons”
• Brain-dead, talking pig, aliens, computers, robots,
apes, dolphins
• Cyborgs (part human, part machine): how much
of a human being can be replaced by machinery
or artificial parts before personhood is lost?
2) A certain level of intelligence?
• How to define? Merely quantitative or qualitative,
e.g. understanding concepts, having intentionality?
• Not necessary? Baby, mentally disabled
• Not sufficient? Intelligent but not sentient computer,
deep blue, “zombie”
3) Being consciousness and/or having feelings
• Lower animals, e.g. rabbits, chickens
• Does consciousness come in degrees? Is a certain
degree of consciousness necessary?
• How to determine consciousness?
• The Problem of Other Minds
4) Moral agenthood
Kant:
“…rational beings are called persons inasmuch as their nature already
marks them out as ends in themselves” (1785)
Definition of a person: "a thinking intelligent Being, that has reason and
reflection, and can consider it self as it self, the same thinking thing in
different times and places; which it does only by that consciousness,
which is inseparable from thinking, and as it seems to me essential to
it" (Kant, Essay on Human Understanding)
• Kant’s requirements of a person: rationality, autonomy, able to
understand moral judgments and choose to act morally, free will
• Problem cases:
Babies, mentally deficient people, apes, dolphins, computers, robots
Problem cases
Babies, mentally deficient people, apes, dolphins,
computers, robots
Morally responsible vs. morally considerable
– Even if only “persons” are moral agents (hence,
morally responsible) , “non-persons” may be
morally considerable
5) Some combination?
• Having sufficient intelligence, being a moral agent, being
conscious, having free will, (being homo sapiens)?
• What combination would you choose?
• Are the criteria too strict?
• Can fulfilling some criteria be sufficient, e.g. either being
homo sapiens or being sufficiently intelligent and conscious?
Apes and Persons
Great Apes
• Chimpanzees, gorillas, orangutans, bonobos
• Could apes fit all the criteria (except being homo
sapiens)?
• Do apes have:

The Great Ape Project
Campaigning for a United Nations Declaration on Great Apes
Supported by Peter Singer, Jane Goodall, Richard Dawkins, etc.
To create a “community of equals” among people and apes
• Three goals:
• Right to life (except in cases of self-defense, etc.)
• Right to liberty (except where in the ape’s best interest,
or where necessary to protect the public)
• Right to be protected from physical abuse
Implications:
• Ban on using apes in scientific research
• Ban on eating ape-meat (bush meat)
• Ban on using apes in circuses, zoos, tv commercials, pets
Ape rights success
• 2007 Balearic Islands (province of Spain)
passed world’s first laws to grant rights to
great apes
• 2008 Spanish parliament drafted bill to grant
primates right to life and liberty
Criticisms
• Apes cannot enter into a reciprocal
legal relationship with people
– Apes cannot be held responsible
– Apes cannot enter into contracts, obey laws, etc.
– Roger Scruton: only humans have duties and thus only humans
have rights
• People have a natural and justifiable tendency to favor their
own species
• Slippery slope
