Philosophical identity is the relation each thing bears only to itself, which gives rise to many philosophical problems, including the identity of indiscernibles and questions about change and personal identity over time. Qualitative identity and numerical identity must be distinguished. The philosophical concept of identity is distinct from the better-known notion of identity in use in psychology and the social sciences. The sociological notion of identity concerns a person's self-conception, social presentation, and the aspects of a person that make them unique. Identity has been conceptualized considering humans' position within the ecological web of life. The law of identity originates from classical antiquity. The modern formulation of identity is that of Gottfried Leibniz, who held that x is the same as y if and only if every predicate true of x is true of y as well. Some philosophers have denied that there is such a relation as identity. Kind-terms, or sortals give a criterion of identity and non-identity among items of their kind.
