David Werdegar asserts we have an “absolute dependency on the signs and symbols of language” (Letters, 20 July). That is questionable: not everybody thinks in the same way.
Composers clearly think in musical terms that are sometimes difficult if not impossible to verbalise. Roger Penrose, in his 1989 book , uses his own experience, and that of other distinguished scientists, to argue that much scientific and mathematical thought is non-verbal.
