"Robert C. Tucker begins this invaluable book with an analytical look at politics, leadership, and the effect each has on the other. Aligning himself with Plato's view of politics as leadership, Tucker argues that politics is more usefully defined from this perspective than from the more familiar stance of the exercise of power. He maintains leaders must define collective problems, prescribe actions or policies, and finally seek support for their diagnoses and policy prescriptions. Tucker contends that political science must take account not only of leadership by those in state authority, but also of sociopolitical movements for change as vehicles of attempted leadership of political communities. Dividing such movements into those for reform and those for revolution, he illustrates this distinction with examples, including Martin Luther King Jr. as a reform leader and Lenin as a revolutionary one." -- Amazon.com.
