Developments in the United States

Some of the most important developments in political science since it became a distinct academic discipline have occurred in the United States. Politics had long been studied in American universities, but usually as part of the curricula of law, philosophy, or economics. Political science as a separate discipline in universities in the United States dates from 1880, when John W. Burgess, after studying at the École Libre in Paris, established a school of political science at Columbia University in New York City. Although political science faculties grew unevenly after 1900, by the 1920s most major institutions had established new departments, variously named political science, government, or politics.

Political science in the United States in the last quarter of the 19th century was influenced by the experience of numerous scholars who had done graduate work at German universities, where the discipline was taught as Staatswissenschaft (“science of the state”) in an ordered, structured, and analytic organization of concepts, definitions, comparisons, and inferences. This highly formalistic and institutional approach, which focused on constitutions, dominated American political science until World War II. The work of American political scientists represented an effort to establish an autonomous discipline, separate from history, moral philosophy, and political economy. Among the new scholars were Woodrow Wilson (1856–1924), who would be elected president of the United States in 1912, and Frank Goodnow, a Columbia University professor of administrative law and, later, president of Johns Hopkins University, who was among the first to study municipal governments. Their writing showed an awareness of new intellectual currents, such as the theory of evolution. Inspired by the work of Charles Darwin (1809–82), Wilson and others led a transformation of American political science from the study of static institutions to the study of social facts, more truly in the positivist temper, less in the analytic tradition, and more oriented toward realism.

Arthur F. Bentley’s The Process of Government, little noticed at the time of its publication in 1908, greatly influenced the development of political science from the 1930s to the 1950s. Bentley rejected statist abstractions in favour of observable facts and identified groups and their interactions as the basis of political life. Group activity, he argued, determined legislation, administration, and adjudication. In emphasizing behaviour and process, Bentley sounded themes that later became central to political science. In particular, his insistence that “all social movements are brought about by group interaction” is the defining feature of contemporary pluralist and interest-group approaches.

Although Bentley’s effort to develop an objective, value-free analysis of politics had no initial consequence, other movements toward this goal enjoyed more immediate success. The principal impetus came from the University of Chicago, where what became known as the Chicago school developed in the mid-1920s and thereafter. The leading figure in this movement was Charles E. Merriam, whose New Aspects of Politics (1925) argued for a reconstruction of method in political analysis, urged the greater use of statistics in the aid of empirical observation and measurement, and postulated that “intelligent social control”—a concept reminiscent of the old Comtean positivism—might emerge from the converging interests of politics, medicine, psychiatry, and psychology. Because Merriam’s basic political datum at this stage was “attitude,” he relied largely on the insights of psychology for a better understanding of politics. An important empirical work of the Chicago school was Merriam and Harold F. Gosnell’s Non-voting, Causes and Methods of Control (1924), which used sampling methods and survey data and is illustrative of the type of research that came to dominate political science after World War II. Merriam’s approach was not entirely new; in 1908 the British political scientist Graham Wallas (1858–1932) had argued in Human Nature in Politics that a new political science should favour the quantification of psychological elements (human nature), including nonrational and subconscious inferences, a view similarly expressed in Public Opinion (1922) by the American journalist and political scientist Walter Lippmann (1889–1974).

Harold Lasswell (1902–78), a member of the Chicago group, carried the psychological approach to Yale University, where he had a commanding influence. His Psychopathology and Politics (1930) and Power and Personality (1948) fused categories of Freudian psychology with considerations of power. Many political scientists attempted to use Freudian psychology to analyze politics, but none succeeded in establishing it as a firm basis of political science, because it depended too much on subjective insights and often could not be verified empirically. Lasswell, for example, viewed politicians as unbalanced people with an inordinate need for power, whereas “normal” people had no compulsion for political office. Although intuitively insightful, this notion is difficult—if not impossible—to prove scientifically.

Merriam’s Political Power (1934) and Lasswell’s classic Politics: Who Gets What, When, How (1936)—the title of which articulated the basic definition of politics—gave a central place to the phenomenon of power in the empirical study of politics. Merriam discussed how power comes into being, how it becomes “authority” (which he equated with power), the techniques of power holders, the defenses of those over whom power is wielded, and the dissipation of power. Lasswell focused on “influence and the influential,” laying the basis for subsequent “elite” theories of politics. Although the various members of the Chicago school ostensibly sought to develop political science as a value-free discipline, it had two central predilections: it accepted democratic values, and it attempted to improve the operation of democratic systems. Power approaches also became central in the burgeoning field of international relations, particularly after World War II. Hans Morgenthau (1904–80), a German refugee and analyst of world politics, argued succinctly in Politics Among Nations (1948) that “all politics is a struggle for power.”

The totalitarian dictatorships that developed in Europe and Asia in the 1920s and ’30s and the onset of World War II turned political science, particularly in the United States, away from its focus on institutions, law, and procedures. The constitution of Germany’s post-World War I Weimar Republic had been an excellent model, but it failed in practice because too few Germans were then committed supporters of democracy. Likewise, the Soviet Union’s 1936 constitution appeared democratic but in reality was merely an attempt to mask the brutal dictatorship of Joseph Stalin. Works of this period focused on the role of elites, political parties, and interest groups, on legislative and bureaucratic processes, and especially on how voters in democracies make their electoral choices. This new interest in actual political behaviour became known as “behavioralism,” a term borrowed from psychology’s behaviourism. Whereas most earlier thinkers had focused on the “top” of the political system—its institutions—behavioralists instead explored the “bottom,” especially that which could be quantified. The result was that much of political science became political sociology.
