The Neo-Warfian Hypothesis

i was kind of afoo calling back to an aristotelian a scholasticism. Is the like, strong version of this warfian hypothesis, thoug it's very popular in the sixties and englbart here wants to put together his own neomorpian hypothesis. So if you don't have a term for something, if if your language doesn't have certain tenses, you can't think these thoughts. He says that both the language used by the culture and the capability for effective intellectual activity are directly effected during their evolution by the means by which the individuals control the external manipulation of symbols. Can you give me a nice clean take of that one? Yes
