I suppose a lot of the difference of opinion on whether we think in a language is dependent on what our definition of thinking is. If you believe, e.g., that what we do when we direct our legs while crossing a stream on stepping stones is thinking then, no, we'd best not be thinking in any language or we'd slip and fall on the first stone. With this definition any linguistic connection is just following along with the non-linguistic thinking we do. If helen or Elizabeth Creith were to stop and vocalize about what they were doing when knitting it might resemble what TEd was doing when he was deciding where to set his saw.
