Much of our work is invisible and intangible. You cannot measure it by human means; and sometimes a period of silent reflection will accomplish more good than if the time had been spent in outward activity. Our work is immaterial where we are and what we do; the thing that matters is who we are and what we intend. Constant preoccupation with exterior work handicaps our knowledge of ourselves and of our intentions.
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.)
