Joseph Andrews

From the text:

But as it often happens that the best men are but little known, and consequently cannot extend the usefulness of their examples a great way; the writer may be called in aid to spread their history farther, and to present the amiable pictures to those who have not the happiness of knowing the originals; and so, by communicating such valuable patterns to the world, he may perhaps do a more extensive service to mankind than the person whose life originally afforded the pattern.

In this light I have always regarded those biographers who have recorded the actions of great and worthy persons of both sexes.
