> Even the question whether one can 'think' of something without having a linguistic representation is a topic of active debate.

This seems fairly trivially true just based on how common it is for someone to have 100% full understanding of a concept and then be completely incapable of remembering the word describing it, or even a phrase that conveys a decent approximation.

Linguistic representation can deal with what's-the-word-again place holders though. So, not being able to recall the name of an object or concept does not prevent linguistic thinking.
