Anglo-American philosophers had grown increasingly suspicious of the speculative nature of the metaphysics associated with German idealism. Beginning in the 1930s and continuing well into the 1950s, analytic philosophy, particularly logical positivism, dominated most major philosophy departments in the United States. Analytic philosophers came to view the aims of philosophy as akin to those of the sciences, and thus sought to narrow the range of philosophical inquiry to raise only those questions that could produce verifiable results.
