“By now you will not be surprised to learn that Gaston Bachelard had a few things to say about the element of air. In a book called "Air and Dreams". he points out that we categorize many of our emotions by their relative weight; they make us feel heavier or lighter. Perhaps because uprightness is the human quality, we imagine human emotions arranged on a vertical scale from ground to sky. So sadness is weighed down and earthbound. joy is aerial, and the sensation of freedom defies the bonds of gravity. "Air," Bachelard writes, "is the very substance of our freedom, the substance of superhuman joy." Elation, effervescence, elevation, levity, inspiration: air words all, alveolated with vowels, leavening the dough of everyday life.”
