Book excerpt: These essays by the brilliant historian of political science Juan Linz comprise a remarkable intellectual review of the life and work of Robert Michels, his major book Political Parties, and the dimensions of democracy as a functioning system.Linz elucidates the importance of Michels in a way that offers more than a mechanical view of political parties as some sort of precisely ordered system of authority and influence. Instead, Michels offers a view of politics that is bottom up and untidy, what he calls a "reciprocal deference structure." Michels is not simply the father of the iron law of oligarchy, but the idea of politics as a less than orderly network of responsiveness, responsibility, and accountability. Linz demonstrates, with magisterial power, why Michels must be ranked as a foremost thinker in classical political sociology. The remaining three segments of the volume cover areas with which Linz has also long been identified. Each in its own way illumines aspects of Michels as well.

The next essay explains why Spain is neither a traditional society nor a successful modern nation. The reliance upon central authority displaced the hoped for evolution of a society based on representative democratic institutions. The final section.

This segment provides a bridge between Michels and Weber--not to mention both of these major figures with Linz himself. The role of state power in mediating intellectual freedom is the leitmotif that blankets the twentieth century. The work is graced by a full-length bibliography o
