Love is not primarily a relationship to a specific person; it is an attitude, an orientation of character which determines the relatedness of a person to the world as a whole, not toward one "object" of love... If I truly love one person, I love all persons, I love the world. I must be able to say, "I love in you everybody. I love through you the world, I love in you also myself."
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.)
