108. The Philosophy of Logic and Language

The purpose of this topic is to enable you to examine some fundamental questions relating to reasoning and language. The philosophy of logic is not itself a symbolic or mathematical subject, but examines concepts of interest to the logician. If you want to know the answer to the question 'What is truth?', this is a subject for you. Central also are questions about the status of basic logical laws and the nature of logical necessity. What, if anything, makes it true that nothing can be at the same time both green and not green all over? Is that necessity the result of our conventions or stipulations, or the reflection of how things have to be independently of us? Philosophy of language is closely related. It covers the very general question how language can describe reality at all: what makes our sentences meaningful and, on occasion, true? How do parts of our language refer to objects in the world? What is involved in understanding speech (or the written word)? You may also investigate more specific issues concerning the correct analysis of particular linguistic expressions such as names, descriptions, pronouns, or adverbs, and aspects of linguistics and grammatical theory.
