The appeal to posterity springs from the pure, strong feeling of the existence of something imperishable; something that, even though it be not at once recognised, will in the end be gratified by finding the minority turn into a majority.
When a new literature succeeds, it obscures the effect of an earlier one, and its own effect predominates; so that it is well, from time to time, to look back. What is original in us is best preserved and quickened if we do not lose sight of those who have gone before us.
The most original authors of modern times are so, not because they produce what is new, but only because they are able to say things the like of which seem never to have been said before.
Thus the best sign of originality lies in taking up a subject and then developing it so fully as to make every one confess that he would hardly have found so much in it.
There are many thoughts that come only from general culture, like buds from green branches. When roses bloom, you see them blooming everywhere.
