Bertrand russell, In his paper on "vagueness," claims that all language is vague. His first argument is that language is vague because all words-Physical-Object words, Logical words, Proper names, Etc.-Are vague. Or, To state the argument more fully: a word is vague if it is a word the extent of whose application is essentially doubtful; all words have an extent of application that is essentially doubtful; hence all words are vague. There are several difficulties, Most of which result from russell's (...) use of the phrase 'essentially doubtful'. Physical-Object words may be used vaguely. But to say that words may be used vaguely is not the same as saying that they are vague. Similar considerations apply to logical words. Concerning proper names I argue, First, That, Given russell's theory, He cannot consistently maintain that they are vague, And, Second, That the evidence he offers is not evidence for the vagueness of proper names but evidence that we are sometimes in doubt whether or not to give an entity a name. Russell's second argument is that language is a system, And, Since the system is vague, The component parts of the system must be vague. The argument has its difficulties. (shrink)

There is an argument against abortion that should be rejected. It is the argument that abortion is the killing of an innocent human being, and since the killing of an innocent human being is immoral, abortion is therefore immoral. The major premise should be corrected to read: ?Generally speaking, the killing of innocent human beings is immoral'; for in some situations morality demands the killing of the innocent. Moreover, given the deep structure of English and the differences between unborn and (...) born progeny, the question of whether a human fetus is a human being is best answered in the negative.
