The former, which includes logical analysis together with many demonstrations that have given mathematicians much trouble, such as that of the 25th proposition of the seventh book of Legendre's Éléments de géométrie, that the sum of the numbers of faces and vertices of an ordinary polyhedron exceed the number of edges by two. (This particular proposition is included under Listing's Census Theorem.) It is not that these propositions are intrinsically particularly difficult: quite the contrary. But mathematicians, being unaccustomed to logistic deduction, have usually attacked them in an unsuitable way.
