A counterargument to the claim that language is not sufficient for thought could be that while individuals with intact language abilities may exhibit impairments in reasoning and problem-solving due to brain damage or disorders like schizophrenia, these impairments might not be a direct result of language function itself. Instead, they could be caused by damage to other cognitive systems that interact with language, or by the disorder's broader impact on cognitive function. For instance, schizophrenia is a complex disorder affecting various cognitive domains, including attention, memory, and executive functions, which are crucial for reasoning and problem-solving. Therefore, the observed impairments might stem from these broader cognitive deficits rather than a lack of language proficiency. Brain damage can affect multiple brain regions and their connections, leading to a wide range of cognitive impairments. It is possible that the observed deficits in reasoning and problem-solving are due to damage to specific brain regions responsible for these functions, rather than a disruption of language processing itself. While the presence of intact language abilities does not guarantee intact thinking abilities, it is necessary to consider the potential confounding factors, such as broader cognitive deficits or damage to other brain regions, before concluding that language is not sufficient for thought. Further research is needed to disentangle the complex relationship between language and thought and to determine the specific contributions of language to various cognitive processes.
