Further thoughts on Dale Carnegie's book

Also, on further examination, this book should come as no surprise to all who read it: from Wikipedia “The ethic of reciprocity was present in certain forms in the philosophies of ancient Babylon, Egypt, Persia, India, Greece, Judea, and China” in other words this is something that people discovered a long time ago, and Dale Carnegie helped to position it for our modern understanding.   It was true then as it is today, people want to be appreciated and treated fairly, therefore I feel that there exists, a correlation between these concepts: the Golden Rule and Dale Carnegie’s principles.
