Bachelard, I realized, is correct. The contemplation of words themselves leads to reverie, to thinking about thinking, to making dreamlike concatenations that chug through the consciousness and lead to imagination. His example involves contemplations and imaginings about the genders of words and how they suggest all kinds of interweavings and reactions, but noun gender need not be the motivating inspiration. For me, etymology accomplishes the same ends.
Reverie Ann E. Michaels on Bachelard and reverie
In The Poetics of Reverie, Bachelard writes of reveries on words, then moves to reveries on reveries themselves, which brings him to books. Books (philosophy, fiction, and poetry books in particular) are, for Bachelard, a kind of dream made real. Books are places to dawdle and to dream as one reads, places in which the reader can interact with imagination: the reader’s imagination, not the author’s imagination. The author’s work, if it is great, tempts readers into reverie. For this reason, Bachelard says he likes to read his favorite books many times. Each reading produces new reverie.
