“Information” as the disposition to inform, i.e., as a capacity of an object to inform an agent. When the act of teaching me Pythagoras’ theorem leaves me with information about this theorem, it is only natural to assume that a text in which the theorem is explained actually “contains” this information. The text has the capacity to inform me when I read it. In the same sense, when I have received information from a teacher, I am capable of transmitting this information to another student. Thus information becomes something that can be stored and measured. This last concept of information as an abstract mass-noun has gathered wide acceptance in modern society and has found its definitive form in the nineteenth century, allowing Sherlock Homes to make the following observation: “… friend Lestrade held information in his hands the value of which he did not himself know” (“The Adventure of the Noble Bachelor”, Conan Doyle 1892). The association with the technical philosophical notions like “form” and “informing” has vanished from the general consciousness although the association between information and processes like storing, gathering, computing and teaching still exist.
