Sure, but that's a non-sequitur. Sight and hearing are the most important human senses that practically inform consciousness in the sense of where we live, and what we can do. The other 3 (touch, smell and taste) are at best secondary and cannot provide the groundedness in our world experience - you are the easiest prey in the animal kingdom. Language is primarily a tool for communication, not thought [0], and "thought" is a slippery concept when you're lacking a guidance that informs you of the world if you can't see or hear it.

Super interesting quote and link though!
