He is suggesting that the nobility of their style, or the quality of their writing, will be the reason for this. Stendhal is indicating that the writing style of authors in 1840 will not stand the test of time, and will not be able to be appreciated by future generations. He is suggesting that the composing style of authors in 1840 will be too outdated and too various from the composing design of the future to be understood. This quote speaks to the concept that writing designs are continuously changing and progressing, and that authors need to understand this in order to make sure that their writing is still appropriate and understandable in the future.
