Abstract
My essay contains three main chapters (2-4). In chapter 2, I put forward a row of queations to which I (an amateur theoretical physicist) haven't found - or understood - the answers. In chapter 3, I explain my doubts about the (self-)sufficiency of mathematics in theoretical physics. Hasn't there been comparably too little conceptual reflection and too much calculation since the mid seventies? A similar question might be asked - but on completely different grounds - about the use of mathematics and language in quantum mechanics, which I discuss in chapter 4.
