Following the concept of "Quenching the Devil's Darts in the book of Proverbs", I used words from each scripture of the book Ecclesiastes for making a Table of Contents, then categorized the words into different subjects associated with things well known in our life. You can find out what the book tells about Government, who is a Speaker, what is Feminism all about, Geography, Measurements, Natural Sources, Our Body, Optimism, Pessimism, Computers, and many other matters.
