Programming language theory: Thinking the unthinkable
1. Incommensurability Science is often distinguished from other human activities by its progressive nature. It has standards for identifying improvements and methods for accumulating them into an ever improving body of sound knowledge. Such traditional view has been challenged by many philosophers. The most significant blow to the idea of progressive science is incommensurability the idea that two theories do not share a common basis that would allow evaluating them using a common metric. Incommensurable theories do not only have different basic assumptions, but they also ask incompatible questions.
