bullet1 4 - The Practice of this Art

INTRODUCTION TO SECTION FOUR
On The Practice of this Art

All science consists in theory and practice, and since the theory of this Art has been very adequately covered in a compendious way in the previous sections, this fourth and final section deals with the practice of the Art as given in this book. This section is divided into ten parts, for the ten figures of this Art with ten modes of propositions and questions, one mode for each figure, and each part is subdivided into two halves, the first contains the propositions of its figure and the second contains the questions. Now let us first deal with the first half, beginning with the first figure, and the other figures follow in turn.
