CSI for Dummies
CSI stands for Complex Specified Information
Complex meaning it is not simple. Complex meaning it is intricate. And complex because it contains many parts or facets.
(Wm. Dembski takes that meaning and gives it a mathematical form. He does so, because like Galileo before him, he sees science as incomplete without the mathematics. You put something in mathematical form and then someone else can check it. But dummies can't understand this and that is why I created this post)
Specified meaning something is indicated or defined, in detail. A good set of assembly instructions specifies what part goes where and as well as the order to put them together.
Information meaning it is communicated data.
IOW complex specified information is a term to differentiate between Shannon Information and information that has a specific meaning.
Shannon information does not care about content or meaning, ie it does not care about specification. All the weight goes to the number of characters transmitted..
