There are quite a few studies to refute this highly ignorant comment. I'd suggest some reading [0].
From the abstract:
"Is thought possible without language? Individuals with global aphasia, who have almost no ability to understand or produce language, provide a powerful opportunity to find out. Astonishingly, despite their near-total loss of language, these individuals are nonetheless able to add and subtract, solve logic problems, think about another person’s thoughts, appreciate music, and successfully navigate their environments. Further, neuroimaging studies show that healthy adults strongly engage the brain’s language areas when they understand a sentence, but not when they perform other nonlinguistic tasks like arithmetic, storing information in working memory, inhibiting prepotent responses, or listening to music. Taken together, these two complementary lines of evidence provide a clear answer to the classic question: many aspects of thought engage distinct brain regions from, and do not depend on, language."
The resources that the brain is using to think -- whatever resources those are -- are language-based. Otherwise there would be no way to communicate with the test subjects. "Language" doesn't just imply written and spoken text, as these researchers seem to assume.
There’s linguistic evidence that, while language influences thought, it does not determine thought - see the failure of the strong Sapir-Whorf hypothesis. This is one of the most widely studied and robust linguistic results - we actually know for a fact that language does not determine or define thought.
How's the replication rate in that field? Last I heard it was below 50%.
How can you think without tokens of some sort? That's half of the question that has to be answered by the linguists. The other half is that if language isn't necessary for reasoning, what is?
We now know that a conceptually-simple machine absolutely can reason with nothing but language as inputs for pretraining and subsequent reinforcement. We didn't know that before. The linguists (and the fMRI soothsayers) predicted none of this.
Read about linguistic history and make up your own mind, I guess. Or don’t, I don’t care. You’re dismissing a series of highly robust scientific results because they fail to validate your beliefs, which is highly irrational. I'm no longer interested in engaging with you.
I've read plenty of linguistics work on a lay basis. It explains little and predicts even less, so it hasn't exactly encouraged me to delve further into the field. That said, linguistics really has nothing to do with arguments with the Moon-landing deniers in this thread, who are the people you should really be targeting with your advocacy of rationality.
In other words, when I (seem to) dismiss an entire field of study, it's because it doesn't work, not because it does work and I just don't like the results.
