I never saw a book without wanting to read it,' said a Cerebral friend to us the other day. This expresses the interest every person of this type has in the printed page. 'I never see a library without wishing I had time to go there and stay till I had read everything in it.' The most essential thing in the world to any individual is to understand himself. The next is to understand the other fellow. From this course you are going to learn which of the 5 types you are and how to get the best out of it. The Cerebral type or The Thinker is discussed in this volume as well as all key principles of human analysis. Read in English (unabridged).
