A man writing such history is driving more horses abreast in his team

Hilaire Belloc, On the Decline of the Book. The lament for the decline of reading, the decline of the book is of course ageless.

It is an interesting speculation by what means the Book lost its old position in this country. This is not only an interesting speculation, but one which nearly concerns a vital matter. For if men fall into the habit of neglecting true books in an old and traditional civilization, the inaccuracy of their judgments and the illusions to which they will be subject, must increase.

To take but one example: history. The less the true historical book is read and the more men depend upon ephemeral statement, the more will legend crystallize, the harder will it be to destroy in the general mind some comforting lie, and the great object-lesson of politics (which is an accurate knowledge of how men have acted in the past) will become at last unknown.

This seems right.

The excellence of a book and its value as a book depend upon two factors, which are usually, though not always, united in varied proportions: first, that it should put something of value to the reader, whether of value as a discovery and an enlargement of wisdom or of value as a new emphasis laid upon old and sound morals; secondly, that this thing added or renewed in human life should be presented in such a manner as to give permanent aesthetic pleasure.

I have to agree with this assessment of writing history.

To read History involves not only some permanent interest in things not immediately sensible, but also some permanent brain-work in the reader; for as one reads history one cannot, if one is an intelligent being, forbear perpetually to contrast the lessons it teaches with the received opinions of our time. Again, History is valuable as an example in the general thesis I am maintaining, because no good history can be written without a great measure of hard work. To make a history at once accurate, readable, useful, and new, is probably the hardest of all literary efforts; a man writing such history is driving more horses abreast in his team than a man writing any other kind of literary matter. He must keep his imagination active; his style must be not only lucid, but also must arrest the reader; he must exercise perpetually a power of selection which plays over innumerable details; he must, in the midst of such occupations, preserve unity of design, as much as must the novelist or the playwright; and yet with all this there is not a verb, an adjective or a substantive which, if it does not repose upon established evidence, will not mar the particular type of work on which he is engaged.
