"Always there has been some terrible evil at home or some monstrous foreign power that was going to gobble us up if we did not blindly rally behind it"

This quote by Douglas MacArthur talks with the idea of thoughtlessly following a leader or a reason without doubt it. He is suggesting that often times, individuals are presented with a situation where they are told that there is a terrific wickedness in your home or an international power that is threatening them, and they are expected to rally behind it without question. MacArthur is advising against this kind of blind obedience, as it can result in people being made use of and adjusted. He is recommending that individuals should put in the time to inquiry and analyze the scenario before thoughtlessly complying with a leader or a reason. He is also suggesting that individuals need to know the possible effects of thoughtlessly complying with a leader or a reason, as it can result in disastrous results.
