By advocating an enlightened method of theorizing committed to thinking in terms of a system of differences, Luhmann has contributed to the development of sociology in a manner that cannot be praised enough. Nonetheless, he does not succeed in giving an account of his own position that satisfies the very logical preconditions that he himself has formulated for it. Instead, his systems theory paradigm of sociology is based on metaphysical premises characteristic of the identity-logical thought of "Old Europe." In fact, (...) the only way to make Luh mann's approach truly comprehensible is to reconstruct it as a new version of Hegel's dialectic. (shrink)
