Lightness is a philosophical concept most closely associated with continental philosophy and existentialism, which is used in ontology. The term "lightness" varies in usage but is differentiated from physical weight, such as "the lightness of balsa wood". In other words, "light like a bird," as Paul Valéry wrote, "and not like a feather".
