Order An Introduction to General Systems Thinking, Silver Anniversary edition

If I had to describe the message that this book gets across in three words, I would say “Context is important”. This should be familiar to any Perl programmer.

The book is based on a course that the author ran, and he admits that many people don’t get a lot out of it. I must admit, a lot of the ideas in the book left me thinking “well, I knew that anyway”. I thought the same from time to time about The Pragmatic Programmer, but as with that book, it’s good to have it all in one place, and to be forced to think about the issues again, and in new ways.

Systems Thinking is a meta-discipline (my description) that studies all kinds of systems. Financial, architectural, social, software development, scientific, artistic, ST has something to say about them all. It attempts to identify rules that apply in many disciplines, and even rules about rules. For example, “The principle of indifference: Laws should not depend on a particular choice of notation”.

The author’s style is witty and clear, a joy to read. One of the most memorable examples points out a problem with analysing English grammar:

“Time flies like an arrow.”
“Fruit flies like a banana.”

It is difficult to explain the attraction of this book. All I can say is, I enjoyed it immensely, and I feel that it will bring benefits to my thinking, even if I am not aware of them. I highly recommend this book.

This review is based on the original 1975 edition, which I acquired just before I found out that the book was to be re-released in a Silver Anniversary edition.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
