 Linguistic determinism is historically associated with the writings of Benjamin Lee Whorf (Whorf 1956). Whorf was especially interested in the languages of the indigenous people of America. He famously argued that the Hopi both speak and think about time in ways that are incongruent with European languages and thought. Rather than viewing time as a continuum that flows evenly throughout the universe and that can be broken up into countable events occurring in the past, present, and future, the Hopi are supposed to focus on change as a process. Their conceptual system is also supposed to differ from ours in that it embodies a distinction between things that are or have been accessible to perception versus things that are not, where the latter category includes things in the future as well as mythical and mental constructs.
