ABSTRACT
Summary: Information is anything but a simple concept; ongoing debates are still characterized by rather conflicting opinions. In
what follows information will be considered a basic resource
for any effective theory, whether in physics, biology, or other
fields of research. Designed to provide a powerful description
of certain aspects of reality, effective theories implement the so-
called Peircean triad: object-sign-interpretant. The sign becomes
information about the object for the interpretant. Information is
inherently contextual.
