Federalism in the narrow sense is thus one (but only one)
method of preserving the pleasures of diversity while enjoying the
strength of unity. Viewed from this angle its basic problem is
not so much that from which Prof. Wheare sets out-what are
the conditions for the establishment of successful federal government
?-but the more general one of what relations between
general and regional governments are necessary in order to secure
the continuance of both the strength and diversity sought by the
federal form of government. When we are considering the
financial side, it is particularly important to look at the problem
in this more general manner.
