Personal Identity
Personal identity is the unique identity of persons through time. That is to say, the necessary and sufficient conditions under which a person at one time and a person at another time can be said to be the same person, persisting through time. In the modern philosophy of mind, this concept of personal identity is sometimes referred to as the diachronic problem of personal identity. The synchronic problem is grounded in the question of what features or traits characterize a given person at one time.
Identity is an issue for both continental philosophy and analytic philosophy. A key question in continental philosophy is in what sense we can maintain the modern conception of identity, while realizing many of our prior assumptions about the world are incorrect.
Proposed solutions to the problem of personal identity include continuity of the physical body, continuity of an immaterial mind or soul, continuity of consciousness or memory, the bundle theory of self, and proposals that there are actually no persons or selves which persist over time at all.

Famous quotes containing the words personal and/or identity:
“I was not at all apprehensive about ... disease ... [it] had no terrors for me. The thing I most feared in the world was hunger. That was something of which I had personal knowledge.”
—Madeleine [Blair], U.S. prostitute and “madam.” Madeleine, ch. 4 (1919)
“Unlike Boswell, whose Journals record a long and unrewarded search for a self, Johnson possessed a formidable one. His life in London—he arrived twenty-five years earlier than Boswell—turned out to be a long defense of the values of Augustan humanism against the pressures of other possibilities. In contrast to Boswell, Johnson possesses an identity not because he has gone in search of one, but because of his allegiance to a set of assumptions that he regards as objectively true.”
—Jeffrey Hart (b. 1930)
