Gaston Bachelard said this quote
“ Words are little houses, each with its cellar and garret. Common-sense lives on the ground floor, always ready to engage in foreign commerce on the same level as the others, as the passers-by, who are never dreamers. To go upstairs in the word house, is to withdraw, step by step; while to go down to the cellar is to dream, it is losing oneself in the distant corridors of an obscure etymology, looking for treasures that cannot be found in words. To mount and descend in the words themselves - this is a poet's life. To mount too high or descend too low, is allowed in the case of poets, who bring earth and sky together. ”
