We are particularly interested in how the book affected your perspective.

1. If Abraham Lincoln had written a book explaining his use of the six elements of a proposition in speech and writing, how would the world be different today?

2. One hundred years from now, what effect will the knowledge of Lincoln's Euclidean technique have on the world? How may the world change from the effect of 100 years of open knowledge of Lincoln's use of the six elements of a proposition?

3. If Lincoln had never lived (or his Euclidean technique never revealed), and you were in a profession or situation where the technique would be useful, and you figured it out, would you reveal the technique, or keep it proprietary for your own use? Why?

4. What can be learned from Lincoln’s self-education that you can apply to yourself, to your family, or to your friends?
