There are many great authors of the past who have survived centuries of oblivion and neglect, but it is still an open question whether they will be able to survive an entertaining version of what they have to say.
Meaningful writing has a purpose beyond that of simple entertainment or of generating conversation. Its purpose is to improve society, to improve our life, by teaching us certain truths that the author has learned. John Ruskin puts it well in his essay on books, Of Kings' Treasuries, by saying that good books give us sight. By teaching us what to look for, and the value of those things, we learn to tell apart the good from the bad, to pass better judgements using our sharpened vision. We grow and become wiser. And that is the only sort of writing that ever improves us as people because all the rest, information and entertainment, it just passes by and leaves us in the same state that we are when we first come into contact with it.
