Nothing is inherently and invincibly young except spirit. And spirit can enter a human being perhaps better in the quiet of old age and dwell there more undisturbed than in the turmoil of adventure...
~ George Santayana
All words have a history. But some are particularly interesting to explore when it comes to psychology—because they're directly born from it. How many times have you been mesmerized by something, so captured by it that it was like you were in a trance? The word "mesmerize" dates back to an 18th century Austrian physician named Franz Anton Mesmer (1734-1815). He established a theory of illness that involved internal magnetic forces, which he called animal magnetism. (It would later be known as mesmerism.)
