"Dark times" is what they call it in Norway when the sun remains below the horizon all day long: the temperature falls slowly but surely at such times.A nice metaphor for all those thinkers for whom the sun of mankind's future has temporarily disappeared.

Giorgio Colli and Mazzino Montinari, Berlin, de Gruyter (1980). The Wanderer and His Shadow, aphorism 191, "Dark Times," (1880).)
[Man's] life consists in a relation with all things: stone, earth, trees, flowers, water, insects, fishes, birds, creatures, sun, rainbow, children, women, other men. But his greatest and final relation is with the sun.

To speak truly, few adult persons can see nature. Most persons do not see the sun. At least they have a very superficial seeing. The sun illuminates only the eye of the man, but shines into the eye and the heart of the child.
(Ralph Waldo Emerson (1803-1882), U.S. essayist, poet, philosopher. Nature, ch. 1 (1836, revised and repr. 1849).)
If I venture to displace ... the microscopical speck of dust... on the point of my finger,... I have done a deed which shakes the Moon in her path, which causes the Sun to be no longer the Sun, and which alters forever the destiny of multitudinous myriads of stars.
(Edgar Allan Poe (1809-1849), U.S. author. Eureka, George P. Putnam (1848).
