The Everyman of the Middle Ages was a symbol of what man really was. Chesterton feels that every outside force that came to Everyman had to be abnormal--for instance, 'Death had to be bony'--so he contends in 'Pendennis' that the shapes that intrude on the life of Arthur Pendennis have aggressive and allegorical influences.
'Pendennis' is an epic because it celebrates not the strength of man but his weakness. In the character of Major Pendennis, Chesterton feels that Thackeray did a great work, because he showed that the life of the so-called man of the world is not the gay and careless one that fiction depicts. It is the religious people who can afford to be careless. 'If you want carelessness you must go to the martyrs.' The reason is fairly obvious. The worldling has to be careful, as he wants to remain in the world; the religious man, of whom the martyr was the true prototype, can afford to be careless; he is not necessarily careless of life, but he can put things at their proper value. The martyr facing the lions in the Roman arena knew what life really was; the worldly woman spending her life trying to be in the company of titled people has no real idea of the value of it. It is the religious people who know the world; it is the worldly people who know nothing of it.
With the publication of 'Pendennis' the reputation of Thackeray reached that position which is sought by all authors, that of being able to write a book that should not, on publication, be put to the indignity of being asked who the writer was. Thackeray was now in the delightful position of being well established, a position that very often results in careless and poor work. It has been said with some truth that once a writer is established he can write anything he likes. This is to an extent true, and such work may even be published and fairly popular, but he will find sooner or later that his influence is on the wane.
In the 'Newcomes' Thackeray drew a character in Colonel Newcome, to whom was given the highest of literary honours, that of being spoken of apart from the book--I mean in the way that people speak of Micawber or Scrooge, almost unconsciously, without really having the actual work in which the character appears in mind. Of this book Chesterton says 'the public has largely forgotten all the Newcomes except one, the Colonel who has taken his place with Don Quixote, Sir Roger de Coverley, Uncle Toby, and Mr. Pickwick.'
