Wether is addressing his friend and letting him know of his love that he has discovered, in a letter dated June 16th.

“I am a happy and contented mortal, but a poor historian.”

Werther addresses his friend, Wilhelm, in a letter dated July 18th. 

“Wilhelm, what is the world to our hearts without love? What is a magic-latern without light?”

Besides the obvious connection of love being equal to light, brighting and warming, there can be an alternate thought to this quote. In a later light is one single fleeting flame. The flame is not constant and can often times feel as though it is fleeing or hiding from you. This light can create phantom objects as well with the shadows that are created, constructing an almost imaginary word.
