, particularly the use of language to express concepts and to refer to individuals.
In Naming and Necessity, Kripke considers several questions that are important within analytic philosophy:
  • How do names refer to things in the world? (the problem of intensionality)
  • Are all statements that can be known a priori necessarily
    Logical truth
    Logical truth is one of the most fundamental concepts in logic, and there are different theories on its nature. A logical truth is a statement which is true and remains true under all reinterpretations of its components other than its logical constants. It is a type of analytic statement.Logical...

Kripke's three lectures constitute an attack on descriptivist theories of proper names
Descriptivist theory of names
Descriptivist theory of names is a view of the nature of the meaning and reference of proper names generally attributed to Gottlob Frege and Bertrand Russell...

. Kripke attributes variants of descriptivist theories to Frege, Russell, Ludwig Wittgenstein and John Searle, among others. According to descriptivist theories, proper names either are synonymous with descriptions, or have their reference determined by virtue of the name's being associated with a description or cluster of descriptions that an object uniquely satisfies. Kripke rejects both these kinds of descriptivism. He gives several examples purporting to render descriptivism implausible as a theory of how names get their reference determined (e.g., surely Aristotle could have died at age two and so not satisfied any of the descriptions we associate with his name, and yet it would seem wrong to deny that he was Aristotle). As an alternative, Kripke adumbrated a causal theory of reference, according to which a name refers to an object by virtue of a causal connection with the object as mediated through communities of speakers. He points out that proper names, in contrast to most descriptions, are rigid designators: A proper name refers to the named object in every possible world in which the object exists, while most descriptions designate different objects in different possible worlds. For example, 'Nixon' refers to the same person in every possible world in which Nixon exists, while 'the person who won the United States presidential election of 1968' could refer to Nixon, Humphrey, or others in different possible worlds.
Kripke also raised the prospect of a posteriori necessities — facts that are necessarily true, though they can be known only through empirical investigation. Examples include “Hesperus is Phosphorus”, “Cicero is Tully”, “Water is H2O” and other identity claims where two names refer to the same object.

Finally, Kripke gave an argument against identity materialism in the philosophy of mind, the view that every mental fact

 is identical with some physical fact (See talk). Kripke argued that the only way to defend this identity is as an a posteriori necessary identity, but that such an identity — e.g., pain is C-fibers firing — could not be necessary, given the possibility of pain that has nothing to do with C-fibers firing. Similar arguments have been proposed by David Chalmers.

Kripke delivered the John Locke lectures in philosophy at Oxford in 1973. Titled Reference and Existence, they are in many respects a continuation of Naming and Necessity, and deal with the subjects of fictional names and perceptual error. They have never been published and the transcript is officially available only in a reading copy in the university philosophy library, which cannot be copied or cited without Kripke's permission.

. Kripke is alleged to have misunderstood Marcus' ideas during a 1969 lecture which he attended (based on the questions he asked), and later arrived at similar conclusions. Marcus, however, has refused to publish the verbatim transcript of the lecture. Smith's view is very controversial, and several well-known scholars (for example, Stephen Neale

) have subsequently offered detailed responses arguing that his account is mistaken.

A theory of naming

In the first lecture, Kripke introduced a schematic semi-formal version of the kind of "theory of naming" he was criticising (1980:64–65). He began the second lecture by recapitulating the "theses" of this theory, together with the "noncircularity condition" he had discussed in closing the first lecture. Apparently, the theses and condition had been written up on a board for all to see. This text was reproduced, as quoted below, in the "lightly edited" transcript of 1980 (p. 71).
  1. To every name or designating expression 'X', there corresponds a cluster of properties, namely the family of those properties φ such that A believes 'φX'.
  2. One of the properties, or some conjointly, are believed by A to pick out some individual uniquely.
  3. If most, or a weighted most, of the φ's are satisfied by one unique object y, then y is the referent of 'X'.
  4. If the vote yields no unique object, 'X' does not refer.
  5. The statement, 'If X exists, then X has most of the φ's' is known a priori by the speaker.
  6. The statement, 'If X exists, then X has most of the φ's' expresses a necessary truth (in the idiolect of the speaker). For any successful theory, the account must not be circular. The properties which are used in the vote must not themselves involve the notion of reference in such a way that it is ultimately impossible to eliminate.

Lecture I: January 20, 1970

Kripke's main goals in this first lecture are to explain and critique the existing philosophical opinions on the way that names work.

In the mid-20th century, the most significant philosophical theory about the nature of names and naming was a theory of Gottlob Frege

 and Peter Strawson. However, Kripke believed that the existing arguments against the Frege-Russell descriptive theory of names failed to identify the real problems with the theory.

Lecture II: January 22, 1970

In 'Lecture II', Kripke reconsiders the cluster theory of names and argues for his own position on the nature of reference, a position that contributed to the development of the causal theory of reference

.

Kripke begins by summarising the conclusions drawn in the first two lectures. First, the referent of names is not usually fixed by some property or set of properties that the speaker believes are possessed by the thing or person named. Instead, the referent of names is usually determined by a series of causal links between people who have used the name. Second, when the referent of a name is determined by a property attributed to the thing named, the link is contingent, rather than necessary or essential. People begin using the name 'Jack the Ripper
Jack the Ripper
"Jack the Ripper" is the best-known name given to an unidentified serial killer who was active in the largely impoverished areas in and around the Whitechapel district of London in 1888. The name originated in a letter, written by someone claiming to be the murderer, that was disseminated in the...

' to refer to the person responsible for the murder of five women in London. So, the name was fixed to its referent by a description. However, the person who carried out the murders might have been jailed for another crime and, thus, might never have had the property of murdering those women. So, the link between the property of being a murderer and the person referred to is contingent. Third, identity is not a relation that holds between names. It is a relation that holds between an object and itself. When someone accurately claims that two names refer to the same object, the claim is necessarily true, even though it may be known a posteriori

. Thus, Kripke claims to have successfully refuted the assumption made by everyone before him that anything that is necessarily true will be known a priori.

Importance

In Philosophical Analysis in the Twentieth Century: Volume 2: The Age of Meaning, Scott Soames wrote:
In the philosophy of language, Naming and Necessity is among the most important works ever, ranking with the classical work of Frege in the late nineteenth century, and of Russell, Tarski and Wittgenstein in the first half of the twentieth century . . . Naming and Necessity played a large role in the implicit, but widespread, rejection of the view—so popular among ordinary language philosophers—that philosophy is nothing more than the analysis of language.
