Again, the other chief accusation against Dickens was that his characters and their actions were exaggerated and impossible. But this only meant that they were exaggerated and impossible as compared with the modern world and with certain writers (like Thackeray or Trollope) who were making a very exact copy of the manners of the modern world. Some people, oddly enough have suggested that Dickens has suffered or will suffer from the change of manners. Surely this is irrational. It is not the creators of the impossible who will suffer from the process of time: Mr. Bunsby can never be any more impossible than he was when Dickens made him. The writers who will obviously suffer from time will be the careful and realistic writers; the writers who have observed every detail of the fashion of this world which passeth away. It is surely obvious that there is nothing so fragile as a fact, that a fact flies away quicker than a fancy. A fancy will endure for two thousand years. For instance, we all have fancy for an entirely fearless man, a hero: and the Achilles of Homer still remains. But exactly the thing we do not know about Achilles is how far he was possible. The realistic narrators of the time are all forgotten (thank God); so we cannot tell whether Homer slightly exaggerated or wildly exaggerated or did not exaggerate at all, the personal activity of a Mycenæan captain in battle: for the fancy has survived the facts. So the fancy of Podsnap may survive the facts of English commerce: and no one will know whether Podsnap was possible, but only know that he is desirable, like Achilles.
