Abstract
This is the first volume in the tetralogy on the foundations of the philosophy of information. The reader interested in an introduction to its topics may find Information - A very Short Introduction helpful. The book fulfils three goals. The first is metatheoretical. The book describes what the philosophy of information is, its open problems, and its methods. The second goal is introductory. The book analyses the complex and diverse nature of informational concepts and phenomena, and defends the veridicality thesis and a theory of strongly semantic information. The third goal is constructive. The book tackles some classic philosophical questions in information-theoretical terms, such as how symbols acquire their semantics (the symbol-grounding problem), whether knowledge may be something different from justified true belief (the Gettier problem), or what kind of realism may be more plausible in philosophy of science (the debate on structural realism). The essential message is quite straightforward. Semantic information is well-formed, meaningful and truthful data; knowledge is relevant semantic information properly accounted for; humans are the only known semantic engines and conscious informational organisms who can develop a growing knowledge of reality; and reality is the totality of information (notice the crucial absence of "semantic").
