I want to know the answer to the following question:
When was logical empricism formulated?
All the background I'm provided with is that "Logical empiricism (also logical positivism or neopositivism) was an early 20th-century attempt to synthesize the essential ideas of British empiricism (e.g. a strong emphasis on sensory experience as the basis for knowledge) with certain insights from mathematical logic that had been developed by Gottlob Frege and Ludwig Wittgenstein.". Is that enough to answer the question?
Answer: yes
