Remember that in the US, we didn't have a King, or a strong central Church, so folks had no one to dictate what was to be. As a result, in the US various groups had various ideas, often divergent. Pragmatism developed: what can we agree to, in order to get something done? This was not the case in Europe.
I hardly agree that analytical philosophy was an American movement. It was an English speaking countries movement. Why? It was in the English speaking countries that language was viewed as word thoughts that meant what they said: Plain talk. Other countries had languages that used implied or inferred meanings. If you ever whisper secrets to a "friend" in France, or Italy, it is what you imply what is the message. In English speaking countries, you have to say it.
HOW ARE PRAGMATISM AND ANALYTIC PHILOSOPHY UNIQUELY AMERICAN MOVEMENTS? AND WHAT ARE SOME IDEAS THAT MAKE THEM DIFFERENT FROM THE WAY EUROPEANS OF THE SAME PERIOD WERE THINKING?
