People in medieval times used to like to organize and categorize and enumerate things. They were very tidy. There’s a book called “The Kalendar and Compost of Shepherds”, which was published by Guy Marchant in Paris in 1493, and was translated into English c. 1518, and was republished by H & J Pillans & Wilson, Edinburgh, in 1931. Which I say because there’s also a book called “The Calendar of Shepherds” which is totally different.
So, one of the things they did in this book was look at the seven deadly sins. All right, you have something like Pride-- what falls under Pride? What’s the worst kind of Pride? What’s the lesser forms of Pride? What are examples of each kind of Pride?
Over-confidence and insecurity are often two sides of the same coin— “I’m the greatest and you’re not going to tell me that there’s a better way to do x” vs “Oh, I’m so awful, I need you to tell me that I’m the greatest so that you don’t let me keep thinking I’m awful.” It’s an exaggeration, but you know what I mean.
