Logical empiricism of the 1930s was quite different from logical empiricism as it thrived in the 1950s. This later version is better known in part because it was codified by Thomas Kuhn's influential book The Structure of Scientific Revolutions (1962). Kuhn attacked “that image of science by which we are now possessed” (1962, 1) - an image of theories as logically transparent structures reaching from observations to abstract theory and changing in time by acquiring or modifying concepts and statements. This image of science went hand in hand with logical empiricism's interests in the logical structure of theory and procedures such as explanation and confirmation.

Yet the project that Kuhn attacked was itself very young. Kuhn wrote Structure in the late 1950s after a transformation had taken place, specifically, a narrowing in the scope, of the values and goals of logical empiricism. For Kuhn, logical empiricism was a philosophy of science concerned mainly with logic and using logic to understand science.
