The philosophy of information (PI) is the area of research that studies conceptual issues arising at the intersection of computer science, information science, information technology, and philosophy.
It includes:
The philosophy of information (PI) has evolved from the philosophy of artificial intelligence, logic of information, cybernetics, social theory, ethics and the study of language and information.
The logic of information, also known as the logical theory of information, considers the information content of logical signs and expressions along the lines initially developed by Charles Sanders Peirce.
One source for the philosophy of information can be found in the technical work of Norbert Wiener, Alan Turing (though his work has a wholly different origin and theoretical framework), William Ross Ashby, Claude Shannon, Warren Weaver, and many other scientists working on computing and information theory back in the early 1950s. See the main article on Cybernetics.
Some important work on information and communication was done by Gregory Bateson and his colleagues.
Later contributions to the field were made by Fred Dretske, Jon Barwise, Brian Cantwell Smith, and others.
