Unfortunately, there is no book I know of that gives adequate treatment even to the role of cryptography in computer security, let alone to the entire subject of computer security, so we learn the hard way, from our mistakes. The only book I know that places this topic in proper perspective is "Cryptography's Role In Securing The Information Society" created in 1996 by the Computer Science and Technology Board of the National Research Council, and published by the National Academy Press. This latter book is kind of interminably boring, and it raises far more questions than it answers, but it's the best we've got; it's well balanced, and was prepared by a group of hard-bitten scientists and engineers with lots of practical experience (plenty of it bad.) So if you want to know how cryptography relates to computer security (maybe), read this latter book, not Seberry and Pieprzyck.

Certainly the subject matter (von Sternberg) is of importance to film and photography buffs but the reader of von Sternberg's life and works would be better served reading von Sternberg's "Fun In A Chinese Laundry." The information contained in Weinberg's book is sufficient for a 2 star rating, but not more.

Actually belief is one of the "classical" modes of possible attitudes: doubting, supposing, knowing and believing. These attitudes as the insight into a subject matter will make the distinction between knower and believer. The latter is able to regard a subject as true and real even without knowing the subject at all. It seems essential that two elements are presented when someone acts as a believer: unfamiliarity (lack of knowledge) with the subject matter and unconditional conviction of the truth. In other words, content cannot be verified but it's accepted. Also believing involving a person on whom the believer relies on.
The author discusses the importance of other two elements: to believe in something and to believe someone. The condition of believing in someone gives to belief a meaningful human act. Besides the fact of believing in something or someone, the author states that belief is driven by willing and love, it can't be demanded or be-stowed. The believer is placed in a condition of seeing something that would never be attainable by his/her own unaided sight, of seeing with the eyes of whom he/she believes.
Another idea shared by the author is seeing and knowing takes precedence over belief. Before someone accepts the testimony of another person, normally called witness, he/she must be sure that this person has authentic knowledge of those things, which are accepted in faith. In this sense, people's credibility and knowledge are judged as part of the believing process.
The author relates belief to freedom. No one who believes must believe, it's naturally a free act. The believer has an alternative of choice, believe or not believe, that is based on a set of processes that the author defines as "mental unrest". These processes are searching investigation, probing consideration, conferencing with oneself before deciding and being on the track of.
As a climax of the discussions presented, the author presents belief in two concepts: "acceptance of the principles of a religion" and Karl Jasper's concept of belief as a modern thought. In the former concept, the witness is God Himself. There is a revelation from God to man where He is conceived as a personal being capable of speech and the man is conceived as a being by nature receptive to God. In the latter concept, the author criticizes the arguments used by Karl Jaspers that leads to the questioning of the traditional religion belief. The author explores in more details how the belief assumes the actuality of revelation and how the modern experience of the "absence" of God leads to the "troubled atheism".
After discussing all the concepts above, the author digs into the principles of the Christianity believes: Trinity and Incarnation. He finishes the book with the question: Is it good to believe? The answer is based in the following: If God has really spoken, it is not only good to believe Him; rather the act of believing generates those things which in fact are goodness and perfection for man.
I think the book is well organized covering the topic from different angles and the author mentions opinions of people with different thoughts. At the end, the author biases the conclusion telling his believes in Christianity.
The book is easy to read because the author explains the ideas and "tries" to prove them in a logical way. Definitively this is not a scientific book. It deals with a controversial theme giving different thoughts based on religion and philosophical principles.
