Who Contains Himself Goes Seldom Wrong.

Only The Wisest And Stupidest Of Men Never Change.

To See What Is Right And Not To Do It Is Want Of Courage, Or Of Principle.

The Strongest Memory Is Not As Strong As The Weakest Ink.

Who Keeps The Old Akindle And Adds New Knowledge Is Fitted To Be A Teacher.

To Know, Is To Know That You Know Nothing. That Is The Meaning Of True Knowledge. When You Say Something, Say What You Know. When You Don't Know Something, Say You Don't Know. That Is Knowledge.
