The philosophy of information is a new area of research. We didn’t study it when we were students, partly because we didn’t realise that the glasses were on our noses. There’s a lot of philosophy from the ancient Greeks to the present day that discusses what we now think of as the philosophy of information, it’s just that it wasn’t called that, and the focus of our society, our cultural interest, wasn’t on this particular concept. But in ethics, for instance, when you discuss what it takes to make the right decision, it takes a well-grounded rational, well-informed agent. In Epistemology the foundation of knowledge requires some initial of information that you need to justify, warrant, and support. And so on. The philosophical discourse has always included an interest in what we would today call information.
