A theory can accordingly be seen as an attempt to simplify things.Such an observation may come as a surprise to those who have often heard remarks to the effectthat such and such a theory is difficult, or at the least terribly complicated. We should neverthelessremind ourselves that a theory involves an attempt to simplify things – it is the world out there thatis the complicated entity.
