The late, great Sir Arthur C. Clarke wrote about hope in the 1984 introduction of his book, Profiles of the Future. Specifically, Clarke wrote of his hope for a future without concern for politics and economics. An excerpt from his introduction appears below.
I also believe - and hope - that politics and economics will cease to be as important in the future as they have been in the past; the time will come when most of our present controversies on these matters will seem as trivial, or as meaningless, as the theological debates in which the keenest minds of the Middle Ages dissipated their energies. Politics and economics are concerned with power and wealth, neither of which should be the primary, still less the exclusive, concern of full-grown men.
