Here is the past and all its inhabitants miraculously sealed as in a magic tank; all we have to do is to look and to listen and to listen and to look and soon the little figures - for they are rather under life size - will begin to move and to speak, and as they move we shall arrange them in all sorts of patterns of which they were ignorant, for they thought when they were alive that they could go where they liked; and as they speak we shall read into their sayings all kinds of meanings which never struck them, for they believed when they were alive that they said straight off whatever came into their heads. But once you are in a biography all is different.
