Quoting General Lionel Max Chassin on the definition of skeptics

Obsessed with the notion of his own omniscience, it enrages him to be confronted by phenomena that do not agree with this conviction. Finding in his limited armoury no explanation that satisfies him, he chooses to doubt rather than himself, and rejects the most obvious facts in order to avoid putting his faith to the test. The mistaken pride and anthropocentrism that supposedly went out with Copernicus and Galileo make him a peril to science, as history abundantly proves. … That strange things have been seen is now beyond question, and the “psychological” explanations seem to have misfired. The number of thoughtful, intelligent, educated people in full possession of their faculties who have “seen something” and described it grows every day. Doubting Thomases among astronomers, engineers and officials who used to laugh at “saucers” have seen and repented. To reject out of hand testimony such as theirs becomes more and more presumptuous.
