do we need to see in order to feel darkness?
how much light do people need in order to live, and how much darkness?
are there things we can experience only in dark, shaded places, in the darkness of night?
is it even possible to imagine things without light?
is there such a thing as bad light?
what do we want to illuminate, and how long for?
can we see something without interacting with it?
