A Word from the Publisher:

The question of fate and destiny that forms the subject matter of this book is a philosophical question, and should normally be looked for in the books of philosophy. But here in this book it has been taken out of its proper context and placed along with some other questions.

All scientific and philosophical questions are classed in accordance with the subject with which they deal or the purpose for which they are studied.

The reason why the philosophical questions form one class, the mathematical another and the physical a third, is that there is a special common link between the questions dealt with by each set of these questions or at least there exists some common theoretical or practical objects which may be achieved by its study.
