Description du produit

Revue de presse

Splendidly pellucid. (Steven Poole, The Guardian)

Présentation de l'éditeur

We live an information-soaked existence - information pours into our lives through television, radio, books, and of course, the Internet. Some say we suffer from 'infoglut'. But what is information? The concept of 'information' is a profound one, rooted in mathematics, central to whole branches of science, yet with implications on every aspect of our everyday lives: DNA provides the information to create us; we learn through the information fed to us; we relate to
each other through information transfer - gossip, lectures, reading. Information is not only a mathematically powerful concept, but its critical role in society raises wider ethical issues: who owns information? Who controls its dissemination? Who has access to information?

Luciano Floridi, a philosopher of information, cuts across many subjects, from a brief look at the mathematical roots of information - its definition and measurement in 'bits'- to its role in genetics (we are information), and its social meaning and value. He ends by considering the ethics of information, including issues of ownership, privacy, and accessibility; copyright and open source.

For those unfamiliar with its precise meaning and wide applicability as a philosophical concept, 'information' may seem a bland or mundane topic. Those who have studied some science or philosophy or sociology will already be aware of its centrality and richness. But for all readers, whether from the humanities or sciences, Floridi gives a fascinating and inspirational introduction to this most fundamental of ideas.
ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

L. Floridi est une chercheur bien connu de ceux dont les réflexions mêlent philosophie et information. Ce petit livre a donc pour but d'introduire le lecteur aux différents questionnements qui portent sur l'information. Qu'est-ce qu'une information? Qu'est-ce qu'une donnée (data)? Quels sont les types d'informations? Quelles sont les théories de l'information?

De manière concise mais efficace et intéressante, l'auteur permet à son lecteur d'avoir en main une ébauche de réponse, et de voir où la réflexion en la matière se situe aujourd'hui.

5.0 étoiles sur 5 Comparing Floridi to Seife and Luenberger 18 juin 2013
Par Let's Compare Options Preptorial - Publié sur Amazon.com
Format: Format Kindle Achat vérifié
This great little book is a quickly readable survey of information science, with an emphasis on philosophy and ethics rather than problem solving or business. Two other extremes (not counting the dozen wonderful Dover titles on information theory for under $5 which are certainly worthwhile) include:

1. Luenberger: Information Science

David's book is about $90 US and our databases show it to be the most used IS textbook, even though it is a 2006 edition. In about 450 pages, it covers the practical applications as well as theory of the entire field of information science, from Shannon to smart phones and economics, minus the "wow how cool is IS" as well as the "we're drowning in info and can't get up" spins.

2. Seife: Decoding the Universe: How the New Science of Information Is Explaining Everything in the Cosmos, from Our Brains to Black Holes

Also from 2006, available used for a penny on some Amazon third party offers, 296 pages.

Very Short Intro (VSI- Floridi) fits nicely between the two. Seife is a wonderful page-turner and a must have if you're into information and math. His "zero" book (Zero: The Biography of a Dangerous Idea was a best seller, and also is about 50c used-- an awesome survey of math. Seife covers both practical problem solving and "meta" issues, but is much less thick and ponderous than Floridi, which has to be studied a little more carefully to get the nuances (not a bad thing). But Floridi isn't all "heavy" -- he talks about a researcher in the "near future" (a million years from now) evaluating our current information leaps!

All three texts cover Shannon, but Floridi and Luenberger do so more with generality and reverence, whereas Seife goes into DEEP detail about redundancy, logarithms, the relationship of amplitudes/ signals to codecs (as in Shannon's connecting log forms to entropy), etc. including a great appendix ON logs. If you enjoy math as well as story telling, Seife delivers.

Floridi is of course much more "up to date" in stats (zettabytes!) etc. since he's more current, but you don't really gain or lose anything there, since much of Floridi is about challenging and re-defining at the conceptual, ideational and definitional levels. If you want detailed, applied, usable problem solving, get Luenberger, if you want a "can't put it down" fun read that touches on the fact that we're "really" living in the Matrix, 13th floor, Tron, etc.-- Seife is the ticket. Both Seife and Floridi give that "wow" feeling that we are really information living in information for the sake of, well, information! They both adequately portray the revolutionary wonder of moving from matter to energy to information in our world view, getting more and more universal (or at the risk of induction, which they both trash-- general), at each leap.

The difference is, Floridi is dry and methodical, Seife is fun and amazing, but you need a little more "math love" with Seife on the other hand. Luenberger is, well, a text. Yes, the best text BUT I include him here mostly for the readers that are looking for less wonder and philosophy and more practical "What does all this mean for careers, business, applications, search engines... etc. All three rate 5 stars, for what they intend to be.

Library Picks reviews only for the benefit of Amazon shoppers and has nothing to do with Amazon, the authors, manufacturers or publishers of the items we review. We always buy the items we review for the sake of objectivity, and although we search for gems, are not shy about trashing an item if it's a waste of time or money for Amazon shoppers. If the reviewer identifies herself, her job or her field, it is only as a point of reference to help you gauge the background and any biases.
4.0 étoiles sur 5 A Useful Beginning for My Exploration of the Information Age 19 juillet 2016
Par fitzalling - Publié sur Amazon.com
Format: Broché Achat vérifié
I decided to explore the Information Age with 3 books. Since I hoped that Professor Floridi's book would provide foundational knowledge, it was first. The next two will be Adam Segal's "The Hacked World Order" and Thomas Davenport's and Julia Kirby's "Only Humans Need Apply." I will review these books as I finish them.

Professor Floridi explores information in its various forms - largely digital, but also analogue, quantum, genetic, biological systems, economic (with a brief exposure to game theory) and the ethics of information. Claude Shannon plays an early, and important, role in the development of the mathematical theory of communication. But, if you experience an involuntary cautionary response to the word "math," don't worry, the book doesn't contain much of it. I wish that the book included a little more of the math underlying Claude Shannon's theory of communication, but perhaps Professor Floridi realized that this would be too much for a reader such as me.

The book provides a useful overview of the field. Some of the observations will seem self-evident and little more than common sense. Some I had not encountered before such as "information minus meaning equals data" or said another way "data plus meaning equals information." What algorithms or models that one uses to impose meaning on data is left to the reader.

Igave the book 4 stars and not 5 because of his approach to the ethics of information. Some of the ethics arise from law, which seemed relatively unremarkable. However, he also make the claim that information embodied, for example, in paintings or the environment seem to have ethical rights. The Professor and I could find common ground in agreeing that defacing the Mona Lisa or dumping harmful chemicals into streams and rivers is a very bad idea. I am not sure that I am ready to go as far as he does in extending the concept of independent ethical rights.

The book served the purpose that I described above. Much of the book visited areas with which I had prior familiarity and some of it explored new territory. I occasionally had to review portions of the book to draw out its meaning. It provided a useful foundation for my investigation of the current status of the Information Age. I recommend it.

3.0 étoiles sur 5 Typographical errors 16 octobre 2015
Par Michael Rose - Publié sur Amazon.com
Format: Format Kindle Achat vérifié
Although I consider this a worthwhile book, it is spoilt by many typographical errors.
For someone without a mathematical background, the errors might cause confusion, putting them completely off the text.
I would appreciate receiving a corrected version of the Kindle book. Please remember, there may be more typographical mistakes.
Here are 17 I found:
1. Chapter 1, page 6, location 233: “1 exabyte corresponds to 1018 bytes”. An exabyte is 2^60 bytes, which is about 10^18 bytes.
2. Chapter 2, page 28, location 528 “byte (by eigh £)” Is the word “eight” intended?
3. Chapter 2, page 28, location 528 “256 (28) characters.” The number 28 should be 28.
4. Chapter 2, page 28, location 530 “128 (27) characters.” The number 28 should be 27.
5. Chapter 2, page 33, location 589 “a and 6”. Should be “a and b”.
6. Chapter 2, page 33, location 600 “battery (6) being flat (G).” “(6)” should be “(b)”.
7. Chapter 3, page 40, location 685 “when [275e] once it is written”. What should “[275e]” be?
8. Chapter 3, page 41, location 701 “In the AS system”.”AS” should be “AB”.
9. Chapter 4, page 50, location 813. I think the term “[DBF]” and subsequent occurrences should be “[DEF]”.
10. Chapter 4, page 56, location 916. “2) P-+ S” should be “2) P-> S”.
11. Chapter 5, page 67, location 1056. In “23, where 2 is the number of states and 3 the number of coins.”, “23” should be “23”.
12. Chapter 5, page 67, location 1056. In “all 23 states simultaneously”, “23” should be “23”.
13. Chapter 5, page 67, location 1056. In “containing 2n possible states”, “2n” should be “2n”.
14. Chapter 6, page 81, location 1230. Should “Merries” be “Memes”?
15. Chapter 7, page 100, location 1487. Should “PG4)” be “P(4)”?
16. Chapter 7, page 102, location 1503. The following occurrences of “P(B\AC)” should be “P(B/AC)”.
17. Chapter 8, page 112, location 1653. In “fomg/ information”, should “fomg” be “inforg”?

For the record, I've communicated these errors to Professor Floridi

4.0 étoiles sur 5 Thanks for the information 19 juillet 2012
Par Richard LeComte - Publié sur Amazon.com

Floridi has written a lucid, compact and at times funny examination of the state of thinking about information in the 21st century, in all its manifestations -- from the Internet to economics to reality itself. Floridi is a philosopher, and his much more detailed book on the philosophy of information will take you much deeper into a few of these topics. I like his approach here -- for information to be transmitted and received, it has to be true, which narrows the focus of the study of information. The chapters on economics and ethics are particularly useful to business majors.

5.0 étoiles sur 5 Groundbreaking and visionary, but very short indeed 28 mai 2010
Par Camber - Publié sur Amazon.com
Format: Broché Achat vérifié
Leaving aside the possibility of minds, souls, and the like, people used to think that the ultimate "stuff" of the universe is matter. Then thermodynamics matured during the 19th century, culminating with Einstein's theoretical demonstration that matter can be converted to energy, thus rendering energy apparently even more fundamental than matter. Now, as a result of multiple streams of developments during the 20th century, we live in an age when information is increasingly being viewed as the true ultimate stuff. This is at once both immensely stimulating and perplexing: stimulating because the concept of information has far greater interdisciplinary unifying power than any concept which came before, but perplexing because the concept of information is very abstract and thus elusively slippery.

In this book, Luciano Floridi clearly makes an earnest effort to navigate the difficult terrain presented by the manifold concept of information, and I think he does commendably well. The flow of the book makes sense. He sets the stage by describing how information-saturated our lives have become, to the point where we can be described as "inforgs" living in an "infosphere." He then looks at the concept of information by progressing through increasingly wider contexts: information as data, the mathematical theory of communication of data, semantic aspects of information, physical information (laws of thermodynamics, Maxwell's demon, etc.), biological information (a nicely nuanced discussion), economic information (emphasizing game theory and also touching on Bayes' theorem), a rather creative effort (even if not quite convincing) to reformulate ethical theory from an informational perspective, and finally an epilogue arguing for both the necessity and possibility of merging the natural and manmade worlds.

This broad scope properly reflects most of the key contempary perspectives on information. The follow-up question is whether this breadth comes at the expense of depth, and I think the answer is both yes and no. On one hand, Floridi writes at a fairly high level and thus manages to pack in a good bit of detail; this demands significant concentration by the reader and will make the book hard to follow for readers without at least a little background in the topics discussed. But on the other hand, I did find that the majority of the topics cried out for a much deeper treatment, to the extent that it was sometimes difficult to clearly grasp Floridi's key points because his discussion was simply too brief. In that sense, the book whets the appetite rather than serving up a full meal, so I'm tempted to deduct a star. But it can be argued that the book has fulfilled its mandate of providing a "very short introduction," so let's be generous and stick with 5 stars.

Since this book does a good job of introducing a fundamentally important topic in a groundbreaking and visionary way, and since I don't know of any better book for that purpose, I highly recommend it.
