How does Gaston Bachelard use imagery in The Poetics of Space?

In Bachelard's theories, poetry has dimensions of imagination that touch one's soul without apparent cause or scientific reason. Poetic imagery in itself stimulates a response in the reader that seems to be a forgotten image. The author claims other scientists, i.e., psychoanalysts and psychologists interpret these images from their own analytic, hence biased, points of view. In contrast, Bachelard proposes that imagination is a major power of human nature. The fact that poetic imagery is not subject to the rules of logic does not lessen its reality. The author uses the idea of a house, which is full of sensations and subjective imagination native to anyone who lives in one, as a vehicle to illustrate the reality of poetic imagery. He uses the term "topophilia" to describe his comments on happy spaces.
