Project : Pragmatic Theory Of Information
The pragmatic theory of information (PTOI) is a set of concepts and principles for defining, measuring, and tracking the time evolution of information that derives from Charles Sanders Peirce's general theory of signs and inquiry. Peirce explored a number of ideas about information from the beginning to the end of his career. One set of ideas about the "laws of information" have to do with the logical properties of information. Another set of ideas about "time and thought" have to do with the dynamic properties of inquiry. All of these ideas contribute to the pragmatic theory of inquiry.
Peirce set forth many of these ideas very early in his career, periodically returning to them on scattered occasions until the end, and they appear to be implicit in much of his later work on the logic of science and the theory of signs, but he never developed their implications to the fullest extent.
