personism

thumb|right|130px|Personism states that being human does not give one exclusive claim to moral rights.

Personism is the moral philosophy of personhood as typified by the thought of the utilitarian philosopher Peter Singer. It amounts to a branch of secular humanism with an emphasis on certain rights-criteria. Personists believe that rights are conferred to the extent that a creature is a person. Michael Tooley provides the relevant definition of a person, saying it is a creature that is "capable of desiring to continue as a subject of experience and other mental states".
