There could be functional redundancies or alternative systems at play that we haven't identified, systems that allow thought to access linguistic capabilities even when the specialized language areas are offline or unnecessary. The question of what "language in thought" looks like remains open, particularly in tasks requiring comprehension. This underscores the need for further exploration into how thought operates and what role, if any, latent or alternative linguistic functionalities play when conventional language regions aren't active.
In short, we may have a good understanding of language in isolation, but not necessarily in its broader role within the cognitive architecture that governs thought, comprehension, and meaning-making.
All other things being equal, its is a reason to provisionally reject the hypothesis that those kinds of thought use language as introducing entities (the ties between those kinds of thought and language) into the model of reality being generated that are not needed to explain any observed phenomenon.
The parent article is mostly about thinking without "words", not necessary without a "language".
Some thoughts might be completely different from sentences in a language, probably when they have a non-sequential nature, but other thoughts are exactly equivalent to a sentence in a language, except that they do not use the words.
I can look and see to things that I recognize, e.g. A and B, and I can see that one is bigger than the other and I can think "A is bigger than B" without thinking at the words used in the spoken language, but nonetheless associating some internal concepts of "A", "B" and "is greater than", exactly like when formulating a spoken sentence.
I do not believe that such a thought can be considered as an example of thinking without language, but just as an example that for a subset of the words used in a spoken language there is an internal representation that is independent of the sequence of sounds or letters that compose a spoken or written language.
