1. Should we focus on Euclid’s Elements if the text we use today is a “product of many hands”? 

2a. Does it bother you no matter how many zeros you add up it's always going to be zero? 

2b. Is this a mathematical argument or is it not an argument at all (an intuitive:having the ability to know or understand things without any proof or evidence)? 

3. The book does not want to attempt to define “common sense” but is there a way to define common sense? If there is, what is it? 

4. Do you find it interesting that the book is having a conversation in it? (it starts on page 23 and goes on) 

5. Is figure 8 on page 29 what you had in your mind when they were talking about positive diameter and points AB?
