The classic writers of course, Arthur C. Clarke, H.G. Wells, Frank Herbert, Stanislav Lem, William Olaf Stapledon, Isaac Asimov, Philip K. Dicks, etc. There are also a few not so well known “hybrid” writers, as Edgar calls them. Writers who are also looking far beyond speculation and random experiments, some who’re using their knowledge and consciousness to open doors beyond our normal everyday reality, like Gustav Meyrink, E.B.-Lytton, E.Haich, and Maria Szepes to name a few.
