"lesson of the moth"

Given to me by Elodie Via email with the following context:

"Archy is a cockroach with the soul of a poet...

'expression is the need of my soul,' declares Archy, who labored as
a free-verse poet in an earlier incarnation. At night, alone, he dives
furiously on the keys of Don Marquis' typewriter to describe a
cockroach's view of the world, rich with cynicism and humor. It's
difficult enough to operate the typewriter's return bar to get a fresh
line of paper; all of Archy's dispatches are written lowercase, and
without punctuation, because he is unable to hit both shift and letter
keys to produce a capital letter."
