Two hypotheses associated with Benjamin Lee Whorf, W1, or the linguistic relativity hypothesis, and W2, or the linguistic determinism hypothesis, have overshadowed a third, W3, that champions ethnolinguistic diversity for the benefit of pan–human creativity, problem solving and mutual cross-cultural acceptance. With respect to W3, Whorf is a disciple of Johann Gottfried Herder (1744–1803) with whom he shares many themes and basic perspectives. It may be that different basic methodologies and philosophies of science, particularly those that distinguish linear, quantitative experimentalism from the reborn holistic and ethnographic stress on meaning, will ultimately make it just as difficult to conclude what has been empirically demonstrated with respect to W3 as it already is with respect to W1 and, particularly, W2. Nevertheless, W:3 has a valuable humanizing and sensitizing effect on the language-related disciplines. Indeed, in that respect it may well have value above and beyond its scientific validity.
