存在と無
In addition to epistemology, Bachelard's work deals with many other topics, including poetry, dreams, psychoanalysis, and the imagination. "The Psychoanalysis of Fire" (1938) and "The Poetics of Space" (1958) are among the most popular of his works: Jean-Paul Sartre cites the former and Bachelard's "Water and Dreams" in his "Being and Nothingness" (1943), and the latter had a wide reception in architectural theory circles. In philosophy, this nocturnal side of his work is developed by his student Gilbert Durand.
