This book is about evidence. Its purpose is to shed light on the nature of evidence and to do away with the mystique associated with the meaning of the word. Concepts falling within the subject are defined and explained, as are the different categories of evidence. Without dealing with the question of causation, an explanation of the nature of evidence would not be complete. Part of a complete treatment of the subject is to explain the place and importance of causation. This, the book does, showing the reader how to identify causal relationships and how to answer the question of causation according to the context at hand. Whether you are a student of law, a debater, or someone interested in assessing the evidentiary value of claims or arguments, this book, I trust, will be an indispensable aid to you.
