Publisher's Synopsis
It is vital in a discussion like this that we should make sure we are going by meanings and not by mere words. It is not necessary in any argument to settle what a word means or ought to mean. But it is necessary in every argument to settle what we propose to mean by the word. So long as our opponent understands what is the thing of which we are talking, it does not matter to the argument whether the word is or is not the one he would have chosen. A soldier does not say "We were ordered to go to Mechlin; but I would rather go to Malines." He may discuss the etymology and archaeology of the difference on the march: but the point is that he knows where to go. So long as we know what a given word is to mean in a given discussion, it does not even matter if it means something else in some other and quite distinct discussion.
