Those aren't mutually exclusive, stimulus and bodily perception enable higher-level thoughts about the physical world. Once I was driving a big cheap pickup with a heavy load on an interstate, and a rear tire violently blew out, causing the truck to sway violently. I operated entirely by feel + my 3D mental model of a moving truck to discern what and where went wrong and how to safely pull over. It was too fast and too difficult for any stupid words to get in the way.

I am glad humans are meaningfully smarter than chimps, and not merely more vocal. Helen Keller herself seemed to think that learning language finally helped her understand what this weird language thing was:

  I stood still, my whole attention fixed upon the motions of her fingers. Suddenly I felt a misty consciousness as of something forgotten—a thrill of returning thought; and somehow the mystery of language was revealed to me. I knew then that w-a-t-e-r meant the wonderful cool something that was flowing over my hand. The living word awakened my soul, gave it light, hope, set it free!

It is not like she was constantly dehydrated because she didn't understand what water was. She realized even a somewhat open-ended concept like "water" could be given a name by virtue of being recognizable via stimulus and bodily perception. That in and of itself is quite a high-level thought!
