Those were the days in this country where H. G. Wells, Bernard Shaw and Conan Doyle could have influence, and thats gone, thats true. But I dont think we have less influence in the hearts and minds of readers. I think, if anything, we have just as much, if not more.
There is a German word, Sehnsucht, which has no English equivalent; it means 'the longing for something'. It has Romantic and mystical connotations; C.S. Lewis defined it as the 'inconsolable longing' in the human heart for 'we know not what'. It seems rather German to be able to specify the unspecifiable. The longing for something - or, in our case, for someone.
One of the troubles is this: the heart isn't heart-shaped.
