Book about thinking

This book was written in the 19th century by Nathan C. Schaeffer.
This book is very interesting, but it was last published at the beginning of the 20th century. It does not attract the reader with its appearance and design, so I decided to change the look and design of this book to make it attractive to the eyes. Now reading it, you will not understand that it was written in the 19th century.
