Word and Object is a 1960 work by the philosopher Willard Van Orman Quine, in which the author expands upon the line of thought of his earlier writings in From a Logical Point of View (1953), and reformulates some of his earlier arguments, such as his attack in "Two Dogmas of Empiricism" on the analytic–synthetic distinction. The thought experiment of radical translation and the accompanying notion of indeterminacy of translation are original to Word and Object, which is Quine's most famous book.
Synopsis
Quine emphasizes his naturalism, the doctrine that philosophy should be pursued as part of natural science. He argues in favor of naturalizing epistemology, physicalism as against phenomenalism and mind-body dualism, and extensionality as against intensionality. He also develops a behavioristic conception of sentence-meaning, theorizes about language learning, speculates on the ontogenesis of reference, explains various forms of ambiguity and vagueness, and recommends measures for regimenting language so as to eliminate ambiguity and vagueness as well as to make a theory's logic and ontic commitments perspicuous ("to be is to be the value of a bound variable"). He argues, moreover, against quantified modal logic and the essentialism it presupposes, argues for Platonic realism in mathematics, rejects instrumentalism in favor of scientific realism, develops a view of philosophical analysis as explication, argues against analyticity and for holism, against countenancing propositions, and tries to show that the meanings of theoretical sentences are indeterminate and that the reference of terms is inscrutable.
Behaviorism
Central to Quine's philosophy is his linguistic behaviorism. Quine has remarked that one may or may not choose to be a behaviorist in psychology, but one has no choice but to be a behaviorist in linguistics.
This influence can be seen in Word and Object. In chapter 2 a linguist has to translate a native's unknown language into English. What is so specifically behavioristic there is that the linguist has nothing to go on but verbal behavior from the native and the visible environment the native interacts with. The same view is displayed in chapter 3 where Quine describes how a baby learns its first words. In this chapter Quine also mentions B.F. Skinner, a well known behaviorist, as one of his influences. The opposite view to Quine's and Skinner's in philosophy of language is represented by Noam Chomsky's linguistic nativism.
Translation and meaning
In the second chapter of Word and Object, Quine investigates the concept of meaning. He shows to what extent his own, empirical, notion of meaning can give an account for our intuitive concept of meaning: 'what a sentence shares with its translation'. Quine also introduces his famous principle of indeterminacy of translation, with the help of the thought experiment of radical translation, i.e. translation of a hitherto unknown language (called Jungle by Quine) into English. The point of this thought experiment is to show that a behavioristic account of meaning does not allow for the determination of the right manual for translating one language into another, as there is no such single right translation manual.
A linguist desiring to translate Jungle has to set up his translation manual based only on the events happening around him/her, the stimulations, combined with the verbal and non-verbal behaviour of Jungle natives. The linguist can thus only use empirical information, therefore, radical translation will tell us which part of our language can be accounted for by stimulus conditions. In the experiment, Quine assumes that functional Jungle equivalents of 'Yes' and 'No' are relatively easy to be found. This allows the linguist to actively query the utterances of the natives, by repeating words (s)he has heard the native utter, and to subsequently record the native's reaction of assent or dissent.
