 Finally, how to put together the ‘local’ and ‘methodological’ styles with what is found in Chevalley and de Lorenzo? In the case of mathematics there is good evidence that the most natural locus for ‘styles’ falls, so to speak, in between these two categories. Indeed, by and large, mathematical styles go beyond any local community defined in simpler sociological terms (nationality, direct membership in a school etc.) and are such that the support group can only be characterized by the specific method of enquiry pursued. On the other hand, the method is not so universal as to be identifiable as one of the six methods described by Crombie or in the extended list given by Hacking. Here are some possible examples, where the names attached to each position should not mislead the reader into thinking that one is merely dealing with ‘individual’ styles.
