Logical Positivism is an influential philosophical movement from the first half of the twentieth century. The movement was founded around 1920 by a group of philosophers, scientists, and intellectuals in Vienna and is known as the Vienna Circle. At the heart of logical positivism (also called, albeit less frequently, logical empiricism) lies the principle of verifiability.
The only significant messages are those that are generally open for verification. Based on this criterion of cognitive significance, much of traditional philosophy and theology is denied as nonsense.
According to logical positivists, the views of most of their philosophical predecessors were not wrong, their failure was more fundamental. They were meaningless.
