One has been tempted to say that “now” is the name of an instant of time, and this, of course, would be like saying that “here” is the name of a place, “this” the name of a thing, and “I” the name of a man. (One could of course also have said “a year ago” was the name of a time, “over there” the name of a place, and “you” the name of a person.) But nothing is more unlike than the use of the word “this” and the use of a proper name, – – I mean the games played with these words, not the phrases in which they are used. For we do say, “This is short” and “Jack is short”; but remember that “This is short” without the pointing gesture and without the thing we are pointing to would be meaningless. ‒ ‒ What can be compared with a name is not the word “this” but, if you like, the symbol consisting of this word, the gesture, and the sample. We might say: Nothing is more characteristic of a proper name A than that we can use it in such a phrase as, “This is A”; & it makes no sense to say, “This is this” or “Now is now” or “Here is here”.
