A web novel from around 2008 had an interesting theme:
intelligence, thought, ideas and coherent information are all aspects of a superdimensional force, existing alongside gravity and electricity. Information is substance, and can be manipulated.
However, a similar idea (in a completely different way) appeared as far as in 1971 in Stanisław Lem's Star Diaries (Professor Donda, a short story where it is found out that information can have a critical mass).
What is the origin, or first appearance of this idea in sci-fi, that information is a substance, or a fundamental force?
