Abstract
Given a set of requirements for a definition of communication, we can
define a communication as information that enters a process and eventually
leaves its inverse process. For example, information is transmitted by speaking
and received after processing by its inverse, hearing. This definition can
be used to precisely describe and explain communication phenomena in an
inclusive and exact manner. The nature of processes and their development
is considered. Communication processes may support other processes, including
non-communicative, evolutionarily adaptive processes supporting
survival and reproduction. Communication is expected to develop in selforganizing
systems, given certain assumptions. Receiving processes may be
understood as information filters and their performance described, predicted,
and understood. These precise definitions of communication and information
can serve as the basis for a science of librarianship.
