We all make mistakes, that is, those of us who are human.
But have you ever been asked to explain a mistake? Ultimately, the only way to explain a mistake is to circularly say "I made a mistake," which is not really an explanation.
Can you explain why you accidentally knocked over a glass of milk? Clumsy? Clumsy is just another word for "prone to making mistakes."
Forget an appointment? "I got mixed up." In other words, I got mixed up because I got mixed up.
So, what is a mistake? Something you did that you did not mean to do? That suggests that the left side of the brain doesn't know what the right side is doing. A circuitry problem.
And there are those who contend that there are no mistakes; that actions are a response to unconscious urges. Calling Dr. Freud.
Mistakes are a key aspect of atonement, as in the day of atonement, or Yom Kippur, which is observed by Jews next month. In this context anything done in violation of God's law must be atoned for.
Life would be easier without mistakes.
But, a large majority of us are human.
